Johdanto:
When people talk about “riveting and welding processing”, they often wonder to which industry it belongs. In fact, rivet welding processing is not an independent industry, but a modern industrial system is a crucial cross-field, basic processing links. It is accurately positioned in the “metal products industry” and “equipment manufacturing industry” at the intersection, is an indispensable support technology for many industries.

I. Core attribution: metal products industry
In terms of the National Standard Industrial Classification of the National Economy, the category that most directly corresponds to riveting and welding processing is “C33 Fabricated metal products industry”. Specifically, it belongs to:

C3311 Manufacture of metal structures: This refers to the production activity of metal components for buildings, bridges, towers and masts, using metals such as iron, steel and aluminium as the main materials. This is the most typical application area for rivet welding processes.

II. Key players: the “bones and muscles” of the equipment manufacturing industry
Rivet welding processing is the core component of “equipment manufacturing”. Almost all large-scale equipment manufacturing can not do without it:

Specialised equipment manufacturing: e.g. chemical vessels, boilers, pressure pipes, etc.

General equipment manufacturing: e.g. machine tool bodies, pump bodies, valves, etc.

Automotive manufacturing: Welding of body-in-white, frame and chassis structures.

Railway equipment manufacturing: Manufacture of car bodies for high speed railways and subways.

Aerospace manufacturing: aircraft frames, rocket fuel tanks, etc. (very high process requirements).

It can be said that riveting and welding processing is for all kinds of equipment manufacturing “bone” and “muscle” process, determines the structural strength, stability and safety of the product.

III. Service model for riveting and welding processing
In the industry chain, riveting and welding processing enterprises usually exist in two modes:

Auxiliary processing plant: Provide professional structural welding and component matching services for large-scale OEMs.

Professional Service Provider: Directly facing end customers, we undertake customised production of non-standard equipment, metal frames, jigs and fixtures.

Yhteenveto:
In short, riveting and welding processing is a basic process spanning the metal products industry and equipment manufacturing industry. It is not an isolated industry, but a core technology that is deeply integrated into and serves almost all heavy industries such as machinery manufacturing, construction engineering, energy and power, and transport. With the development of intelligent manufacturing, automation, robotic riveting is becoming a new trend in this field, but its core position as the industrial “skeleton division” has never changed.

What is the category of rivet welding? A comprehensive analysis from the perspective of both the type of work and the process
Meta Description: Confused about “what category does riveting belong to”? This article will help you to clearly classify the concept of riveting and welding from two dimensions, namely the type of work (riveter/welder) and the process (joining technology).

What category does rivet welding belong to?What’s the best way to do this? A comprehensive analysis from the perspective of both trades and processes
Johdanto:
“The term ”riveting“ often begs the question: does it refer to a trade or a craft? The answer is: both. In order to understand exactly ”what category rivet welding belongs to”, we need to look at it from two different dimensions: the occupational category and the technical process.

I. Classification from the perspective of occupational groups
In the factory and labour system, “riveting and welding” usually refers to two closely related technical trades with different responsibilities:

worker with rivets

Classification: A trade that belongs to the assembly category.

Primary job: To release, lay out, set up, assemble and straighten structural metal parts. They are the “building block builders”, putting the metal parts together accurately according to the drawings and preparing them for welding. Riveters focus more on overall structural accuracy and assembly.

welder

Classification: A joining type of work.

Primary Job: Responsible for permanently joining pairs of parts together using welding equipment and materials. They are the “seamstresses” who form strong welds from molten metal. Welders focus more on the quality, strength and aesthetics of the weld.

Conclusion: At the level of trades, “riveting and welding” is a collective term for the two trades of riveters and welders, who work together to manufacture structural metal parts. One is responsible for “moulding” and the other for “joining”.

II. Classification from the point of view of technical process
From a manufacturing technology perspective, riveting is a non-removable joining process.

Position in the broad category of connectivity technologies:

Removable connections: threaded, keyed, pinned, etc.

Non-removable connections: welding, riveting, gluing, etc.

“The term ”riveting“ itself encompasses the two main non-removable joining methods, welding and riveting. Although welding has become absolutely dominant in modern industry, the historic term ”riveting” is still widely used to refer to this process of permanent joining by heat or pressure.

Position in the material machining process:

Thermal processing: Casting, forging, welding, heat treatment, etc.

Welding (the core of riveting) is explicitly categorised as a type of thermal processing because the process involves the melting and solidification of metal.

Yhteenveto:
So when someone asks, “What category does rivet welding belong to?”, you can answer:

Occupationally, it is a skilled trade in industrial manufacturing, subdivided into riveters and welders.

Technically, it is a non-detachable joining of materials and is an important form of thermal processing.

Understanding these two dimensions of classification helps us to gain a fuller and deeper understanding of the role and value of riveting in industrial production.

NiittihitsausProsessin perusprosessi selitetään yksityiskohtaisesti: 8 keskeistä vaihetta piirustuksesta valmiiseen tuotteeseen | [Sivuston nimi]
Meta Description: Tämä artikkeli on yksityiskohtainen analyysi niittauksen ja hitsauksen perusprosessista, joka kattaa materiaalin, viistämisen, ryhmittelyn, hitsauksen, tarkastuksen ja muut 8 keskeistä vaihetta, jotta voit ymmärtää täysin niitattujen ja hitsattujen osien koko tuotantoprosessin.

Niittaus- ja hitsausprosessin perusprosessi: luettu piirustuksista koko prosessin valmiiseen tuotteeseen asti
Johdanto:
Oletko koskaan miettinyt, miten vahvoja metallirunkoja, suuria laitteita ja rakenneosia valmistetaan niittaamalla ja hitsaamalla? Niittihitsaus ei ole pelkkää "hitsaamista", vaan se on tiukka ja järjestelmällinen prosessi. Niittauksen ja hitsauksen perusprosessin ymmärtäminen on ratkaisevan tärkeää tuotteiden laadun varmistamiseksi ja tuotantokustannusten hallitsemiseksi. Tässä artikkelissa annamme yksityiskohtaisen selityksen jokaisesta keskeisestä vaiheesta suunnittelupiirustuksista lopputuotteeseen.

I. Piirustusten ja teknisten asiakirjojen tarkastelu
Tämä on kaiken työn lähtökohta. Prosessi-insinöörien on tutkittava asiakkaan toimittamat suunnittelupiirustukset ja ymmärrettävä tekniset vaatimukset, kuten materiaalityypit, mittatoleranssit, hitsausstandardit jne. Tämän jälkeen pidetään tuotantotiimin kanssa tekninen tiedotustilaisuus, jossa varmistetaan, että kaikki ovat selvillä työstövaatimuksista ja laatutavoitteista.

II. Hinnan alittavuus
Alaleikkaus on prosessi, jossa raaka-aineet (esim. teräslevyt, profiilit) leikataan piirustusten mukaiseen muotoon ja kokoon. Yleisesti käytettyjä menetelmiä ovat mm:

Liekkileikkaus: Paksuille levyille.

Plasmaleikkaus: nopea, soveltuu keskikokoisille ja ohuille levyille sekä ei-rautametalleille.

Laserleikkaus: Laserleikkaus: Korkea tarkkuus ja hyvä leikkauslaatu.

Leikkuri leikkauskone: Säännöllisesti muotoilluille levyille.

III. Viistäminen
Hitsin tunkeutumisen varmistamiseksi ja hyvän hitsaussauman muodostamiseksi on yleensä tarpeen työstää hitsattavaan reunaan tietyn muotoinen viiste. Yleisiä viisteiden muotoja ovat I-, V-, X-, U- ja niin edelleen. Työstömenetelmiä ovat muun muassa reunojen höyläys, jyrsintä ja liekkiviiste.

IV. Ryhmittely ja pisteiden vahvistaminen
Kokoaa ja yhdistää leikatut ja viistetyt osat piirustusten mukaisesti. Osien suhteellisen sijainnin ja mittatarkkuuden varmistamiseksi käytetään kiinnikkeitä tai jigejä. Kun kokoonpano on valmis, osat "kiinnitetään" lyhyillä hitsaussaumoilla, jotka pitävät osat tilapäisesti paikallaan myöhempää muodollista hitsausta varten.

V. Hitsaus
Tämä on niittihitsauksen keskeinen osa. Valitse sopiva hitsausmenetelmä tuotteen vaatimusten, materiaalin ominaisuuksien ja muiden tekijöiden mukaan:

Elektrodikaarihitsaus: Joustava ja laajalti käytetty.

Kaasusuojahitsaus: Kaunis hitsaussauma.

Uppokaarihitsaus: Pitkät suorat hitsit, joiden laatu on vakaa.

Argonkaarihitsaus: ruostumattomalle teräkselle, alumiinille ja muille materiaaleille, jotka vaativat korkeaa suojausta.

VI. Hitsauksen jälkeinen käsittely
Kun hitsaus on valmis, tuotteen ulkonäköä ja suorituskykyä voidaan joutua parantamaan:

Kuonan poisto ja hionta: Poista kuona ja roiskeet ja hio hitsaussauma sileäksi ja kauniiksi.

Kalibrointi: Kalibrointi: Hitsausprosessin aikana syntyneiden jännitysten ja vääristymien poistaminen.

Lämpökäsittely: Lämpökäsittely: Kriittisille komponenteille suoritetaan jännityksenpoistohehkutus mittojen ja ominaisuuksien vakauttamiseksi.

VII. Laadun tarkastus
Tarkastus on viimeinen keino varmistaa tuotteen laatu. Siihen kuuluvat pääasiassa:

Ulkonäön tarkastus: Tarkasta, onko hitsissä pintavikoja.

Rikkomaton testaus: kuten röntgentarkastus, ultraäänitarkastus, hitsin sisäisen laadun havaitsemiseksi.

Mittatarkastus: Tarkista, että valmiit mitat ovat piirustusten mukaiset.

Painetestaus: Säiliötyyppisille tuotteille on tehtävä vesi- tai ilmanpainekoe.

VIII. Pintakäsittely ja ruosteenesto
Asiakkaan vaatimusten ja käyttöympäristön mukaan valmiille tuotteille tehdään pintakäsittelyjä, kuten hiekkapuhallus, maalaus, galvanointi jne., korroosionestokyvyn ja esteettisyyden parantamiseksi.

Yhteenveto:
Niittaus- ja hitsausprosessin perusprosessiSe on toisiinsa liittyvä järjestelmällinen hanke. Jokainen vaihe vaikuttaa suoraan lopputuotteen laatuun, turvallisuuteen ja käyttöikään. Ammattimainen niittihitsauksen käsittelytehdas valvoo väistämättä tiukasti jokaista linkkiä.

I. Advanced Operating Tips and Experience Sharing Riveting in Space Restricted Positions: Problem: In corners, inside walls of barrels, and other locations that are difficult to reach by sight and tools. Tips: Use a bent-neck headstock or shaped head. Use “blind rivets” (blind rivets) but be aware of their low load capacity. Practise in a simulated position to find the optimum force angle. Riveting of workpieces of different thicknesses: Problem: When joining a thin plate to a thick plate, it is easy to cause deformation of the thin plate or poor riveting. Tip: Use a larger diameter washer on the thin side or special rivets such as “high lock rivets” to spread the pressure. Tips to improve riveting efficiency: teamwork: heating, nail passing, top nail, riveting the seamless integration of the various processes, the formation of assembly line operations. Tooling Improvement: Customise special top handles and riveting moulds to suit specific products. Pre-assembly: Fast and accurate pre-assembly using fixtures and spot welding wherever possible.

Second, the common troubleshooting and solutions Trouble phenomenon Possible causes Solutions Gap around the rivets

1. workpiece is not clamped 2. nail hole diameter is too large 3. rivet length is insufficient 1. increase fixture strength or spot weld density

2. machine holes to standard tolerances 3. recalculate and select rivets of appropriate length Cracked headers

1. quality of rivet material 2. overheating (hot riveting) 3. excessive riveting force (cold riveting) 1. replacement of qualified rivets

2. strictly control the heating temperature and time 3. adjust the air pressure of the rivet gun or the pressure of the riveting machine Rivet head falling off 1. insufficient upsetting height 2. too small clearance between the rivet and the hole 3. injuries at the transition between the original head and the rod 1. ensure that the riveted joint is in place 2. appropriately enlarging the hole or reducing the diameter of the rivet

3. check and replace the defective rivets Compression injury on the surface of the workpiece 1. uneven or dirty surface of the top handle 2. unsuitable riveting gun cover mould 1. grinding the top handle work surface and keep clean 2. select and rivet head matching cover mould 3. special materials and working conditions of the coping strategy Aluminium alloy riveting: very susceptible to cold work hardening, usually use cold riveting. If it must be hot riveting, the heating temperature should be strictly controlled at 200 ° C or less. Stainless steel riveting: high strength, riveting force demand. Pay attention to prevent the rivet and the workpiece to occur “bite” phenomenon, can be appropriate use of lubricants. Riveting in vibration environment: Ensure that the riveted joint is full, if necessary, interference fit riveting, that is, the diameter of the rivet is slightly larger than the diameter of the hole, in order to obtain a very high stability of the connection.

Fourth, from good to excellent: cultivate craftsman thinking Record work log: Record each encountered special cases and solutions to form their own knowledge base. Continuous learning: pay attention to new riveting technology and equipment, such as automatic drilling and riveting technology. Quality Awareness: Always put “quality first” in mind, and be responsible for each rivet. Conclusion The only test of skill is in the field. The techniques and solutions in this manual are based on the experience of countless front-line craftsmen. We hope that it will become a reference tool that you will always have at hand, and that it will serve as a beacon of light for you when you encounter a difficult problem. If you want to review it systematically, you can always turn to our Rivet Welding Basics and Rivet Welding Practices for consolidation.

get itBasics of Rivet WeldingAfter that, the next step is to put it into practice. A standardised method of operation is the key to ensuring riveting quality, improving efficiency and safeguarding personal safety. This article will be like an experienced master at the side, hand in hand to take you through each key step of the riveting operation, whether it is hot riveting or cold riveting, you can find a clear guide.

First, the operation of the pre-preparation: to do a good job, you must first sharpen their tools and equipment check: hot riveting: heating furnace (oil, gas or electric furnace), rivet gun, top handle (top iron), clamps, spanners and so on. Cold riveting: riveting machine, rivet gun (for blind rivets), hand hammer, top handle, etc.. Common tools: pneumatic drill or electric drill, drill, scribe, hammer, magnifying glass, sample plate. Rivet selection: According to the drawing requirements, select the correct material, diameter and length of rivets. Rivet length calculation formula: L = δ + (1.3 ~ 1.5)d, where δ is the total thickness of the plate stack and d is the rivet diameter. Preparation of workpiece: Clean the connection surface of oil, rust and burrs. Position the workpiece according to the scribed line or sample plate and fix it temporarily with jig or spot welding.

Second, the core operation steps (to hot riveting as an example) Clean the hole and heating: use the air drill to clean the rivet hole, make sure the hole wall is smooth. Put the rivets into the heating furnace and heat them evenly until bright orange-red (about 1000-1100°C). Heating should be rapid and even to avoid overcooking or heavy oxidation. Threading and Topping: Quickly insert the heated rivets into the nail holes with a clamp. One worker immediately use the top handle to tighten the rivet at the original end of the rivet. Rivet shaping: Another worker uses the rivet gun to aim at the sticking out end of the rivet rod to impact, first light and then heavy, to upset the rod and fill the nail hole. Then swing the rivet gun around the centre of the nail rod and crush the end of the rod into a semi-circular upsetting head. The action should be rapid, accurate, in the rivet temperature drops to the loss of plasticity before completion. Cold riveting operation points: rivets do not need to be heated, directly into the hole. The header is formed by a single press using a riveting press, or by pulling the mandrel off using a rivet gun. Simpler operation, but requires equipment and rivet strength.

Third, quality inspection and defect analysis after riveting is completed, must be strictly checked: Appearance check: the header should be regular, smooth, no cracks; and the original header should be concentric, there shall be no skew. Dimension check: Use sample plate to check whether the diameter and height of the header meet the standard. Tightness check: Use 0.1mm tape measure to check the fitting surface of the workpiece, and the insertion depth should not be more than 20mm. Common defects: Crooked header: the top handle is not top positive or the angle of the rivet gun is not right. Rivet cracks: poor material quality or improper heating (overcooking). Burying the head is not solid: improper processing of the nail hole or riveting force is insufficient. Safety regulations must wear protective glasses, heat-insulating gloves, earplugs and overalls. Hot riveting pay attention to fire prevention, and to prevent high-temperature rivet burns. When using the rivet gun, the muzzle is strictly prohibited to people. Keep the workplace neat and tidy, and tools are placed in an orderly manner.

Conclusion Following standard operating methods is a sure way to become a competent riveter and welder. Theory combined with practice, more observation, more practice, you will be able to master this skill. Once you have accumulated enough experience, you will be able to cope with a variety of complex working conditions, which is exactly what we will discuss in our next article, “Rivet Welding Handbook: Advanced Techniques and Solutions to Troubleshooting Problems”.

johdanto
Rivet welding is a time-honoured and vital permanent joining technique in modern industrial manufacturing and the joining of metal structures. Whether you are a mechanical student, a new mechanic, or a hobbyist interested in metal fabrication, understanding the basics of rivet welding is the first step toward mastery. This article will systematically introduce you to the core concepts of riveting, providing a solid foundation for further study and practice.

I. What is riveting? Core principle analysis
Riveting, in layman’s terms, is the use of rivets to connect two or more workpieces (usually sheet metal or profiles) in a non-removable manner. The core principle is that the plastic deformation (upsetting) of the rivet stem creates a large axial pressure inside the stem, which tightly presses the connected parts together, thus transmitting and sealing the force.

II. Main types and characteristics of rivet welding
Depending on the operating temperature, process and structural form, rivet welding can be divided into the following categories:

hot riveting

Process: The rivets are heated to a red-hot state (approx. 1000°C) and then riveted.

Advantages: Good plasticity of the rivets, the required riveting force is small, the connection is tight and reliable, especially for large diameter rivets and heavy structures (such as bridges, ships).

Disadvantages: Complicated process, requires heating equipment, high energy consumption, fire risk, high labour intensity for workers.

cold riveting

Process: Direct riveting of rivets at room temperature.

Advantages: Simple process, high efficiency, no thermal influence, good labour conditions.

Disadvantages: High plasticity requirements for riveting materials, riveting force, usually used for smaller diameter (generally less than 10mm) rivets and aluminium alloys and other soft materials.

Classification by riveting method

Impact Riveting: Forming headers using the impact of a pneumatic or hydraulic rivet gun. Most widely used, but noisy.

Pressure riveting: Riveting is done by static pressure using pressure riveting machine. No noise, stable riveting quality and flat surface.

III. Advantages and disadvantages of rivet welding

Pros:

High reliability: Reliable connection, good vibration resistance, commonly used in structures subject to shock and vibration loads.

The quality of the riveted joints can be initially judged by visual inspection.

Suitable for dissimilar materials: Can be used to join different types of metallic or non-metallic materials.

Drawbacks:

High structural weight: Increased structural weight due to the need for lap plates and rivets.

Stress concentrations: Riveted holes weaken the cross-section of the workpiece and are prone to stress concentrations.

Noisy: Especially for impact riveting, the working environment is harsh.

High demands on workers’ skills: High-quality riveting requires experienced craftsmen.

IV. Application areas of rivet welding
Despite the growing popularity of welding technology, riveting still occupies an irreplaceable position in the following areas:

Aerospace: The connection of the aircraft skin to the skeleton, taking advantage of its excellent fatigue resistance.

Steel structure buildings: large-scale factory buildings, stadiums, bridges, etc.

Heavy machinery: frame connections for cranes, excavators and other equipment.

Shipbuilding: Joining of hull structures.

Some high quality leather goods, bags and jeans (metal rivets).
