What is riveting welding

In many sites of mechanical manufacturing and metal processing, the key technology for connecting heavy metal parts relies on the riveting welding process. This process relies on a basic tool called a riveting welding platform. It can be said that this basic tool is the cornerstone of the riveting welding process.

Technical characteristics of riveting welding process

Riveting welding is a specific application of electric welding. The key is to use the welding rod to melt it and penetrate it deeply into the workpiece to be welded, thereby forming a stable connection. This method is particularly suitable for joining thicker metals such as steel plates and large structural parts because it can provide sufficient penetration depth and weld strength to ensure the stability of the structure. In the field of shipbuilding, heavy machinery and steel structure engineering, riveting and welding technology has been widely used. It can effectively cope with working conditions of large loads and strong vibrations, and is an indispensable link in the manufacturing process of many heavy equipment.

Core functions of riveting welding platform

This is a workbench specially designed for riveting welding operations. It is called a riveting welding platform. Its primary function is to provide a reference plane, which must be stable and accurate. Its working surface is generally designed with through holes and T-shaped slots. These structures are of great practical use. Through holes can facilitate the cleaning of oxide scale, welding slag and other waste generated during welding, thereby keeping the work surface clean. T-shaped slots can be used to install positioning blocks, clamps and other fixtures to quickly and firmly fix the workpieces to be welded on the platform, thereby creating conditions for precise welding.

Platform structure and materials

In order to ensure the load-bearing capacity and long-term stability, most of the riveting and welding platforms adopt a ribbed or box-type structure with reinforced ribs inside. This design ensures very high rigidity while reducing its own weight. Its material is usually HT200-250 grade high-strength cast iron, which is wear-resistant and has small deformation. The working surface is finished by scraping and other finishing, and the hardness is controlled between Brinell hardness HB160 and 210, which makes it resistant to scratches from welding tools and maintains long-lasting plane accuracy.

Platform manufacturing and aging processing

After the casting is completed, a qualified riveting welding platform must undergo a strict heat treatment process. Usually, artificial annealing is performed at a temperature of 600 to 700 degrees Celsius to eliminate the internal stress of casting. Subsequently, two to three years of natural aging treatment is required to allow the internal structure of the cast iron to slowly stabilize in the natural environment. This can minimize future deformation of the stress relief platform and maintain accuracy for a long time.

Standards and accuracy levels followed

The production and manufacturing of riveting welding platforms is not carried out randomly. It strictly follows the national machinery industry standard JB/T 7974-2000 and is manufactured in accordance with relevant national standards. The platform is divided into multiple levels according to its flatness accuracy, such as 00, 0, 1, 2, 3, etc., among which level 00 accuracy is the highest. In addition, in addition to the common scraping working surface, there are also platforms using precision planing technology. Users can choose according to different accuracy requirements and budgets.

Platform specifications and selection applications

The riveting and welding platforms have various specifications, including small ones of 100 mm × 100 mm, and large ones of 3000 mm × 6000 mm. Is it profitable to process riveting welding parts ? It can even be customized according to the user’s special design drawings. Its working surface includes rectangular, square or circular, equipped with processable V-shaped, T-shaped grooves and various round holes and long holes. It can adapt to work fixation and welding needs of different shapes, and is widely used in various fields from equipment maintenance to large component assembly.
