Stainless steel equipment riveting and welding manufacturing > HD pictures
When purchasing CT frame stainless steel rivet weldments, what everyone fears most is that the batches are different, and the actual objects do not match the drawings at all. Moreover, if you purchase online now, the risk is also there, so many buyers only react after stepping through this pitfall.
Pictures are for reference only
This kind of thing is often written on the Weiku page, saying that the pictures are only for everyone to look at and play as a reference. They may not be consistent with the actual objects due to different production batches. This means that there may be subtle differences in the specific direction of the welds or the smoothness of the surface, so you must not use screenshots as the final acceptance criteria.
When it comes to precision components like CT gantry, only a few millimeters of welding deformation will affect positioning accuracy. Therefore, before placing an order, you must confirm the tolerance range and welding process parameters with the seller to be sure. It is best to get samples of the same batch to take a look.
The difference between gold membership and supreme VIP
The page of the platform specifically indicates the types of certifications, including gold membership, VIP, supreme VIP, etc. In addition, it also mentions the certification method of Baiwei Tong. As for the order of the review levels, it is from low to high. Among them, which one requires the most complete qualification documents is the supreme VIP category, but correspondingly, the annual fee standard will be the highest.
In the actual operation process, priority should be given to contacting factories with the Baiweitong label. Usually, these factories have ISO system certification and medical equipment supply records. Sellers need to be asked to present shipping documents for the past three years. This is often more effective and useful than checking membership levels.
Legal boundaries of commercial and trade activities
It is written on the page that the purchase is a commercial transaction and the content is the responsibility of the seller. The platform is only responsible for information release. As for quality disputes or delivery breaches, the buyer and seller need to bear the corresponding responsibilities themselves.
Before we sign the contract, we must clearly stipulate and write down the acceptance criteria. For example, weld flaw detection report, qualification certificate, medical equipment (such as CT frame) stainless steel precision riveting , and allowable dimensional deviation values. When disputes arise in the future, these documents will be used as the basis for rights protection. Please remember not to just make an oral agreement.
Process details of stainless steel riveting and welding
A set of CT frame parts must go through steps such as laser cutting, bending, assembly, TIG welding, grinding and pickling passivation. The riveting and welding process is the most critical. As long as there is a slight deviation in the current speed, pores or cracks will appear.
To judge the overall level of that factory, you can actually just look at the condition of the weld. A particularly good weld should be shaped like fish scales. Stainless steel equipment riveting manufacturing > High-definition pictures, and the joints should look smooth. Undercut edges are absolutely not allowed. If you want to see this more intuitively, you can ask the seller to provide relevant photos taken by X-ray inspection or penetrant inspection.
What is the difference between batches?
The nickel content of different heat numbers of 316L plate fluctuates between 10% and 14%. The corrosion resistance of the welding heat-affected zone will change with this situation. Medical equipment has high requirements on this point.
When placing an order, the specific furnace number must be locked so that the material report can mark the corresponding batch. When receiving the goods , medical equipment (such as CT racks) are precision riveted to stainless steel . You need to check whether the heat number and the contract match. Once you find anything wrong, reject the goods immediately. Don't just accept it.
Acceptance process after receiving the goods
Don’t be in a hurry to sign it after it arrives. Please use three-dimensional coordinates or calipers to re-measure the mounting holes of all parts individually, and also carefully measure the straightness of the welds. If the deviation exceeds 0.5 mm, objections must be raised immediately. At the same time, check whether the pickling and passivation treatment has been carried out, and absolutely no rust spots can be seen on the surface.
You need to keep all inspection records and photos so they can be used as proof of payment. If a problem is found, you should notify the seller in writing within the time limit of the contract to reissue or exchange the goods. Because if the delay exceeds the warranty period, you will have no way to make a claim.
