Stainless steel welding issues?
Thread Content
The company wants to acquire several 304 stainless steel steam distributors. The company’s welding specialist said that it’s not possible to weld them, as the company’s welders have no experience with welding stainless steel. I think that as long as the welding parameters are chosen correctly, even if the welder has no experience welding stainless steel, a little training should be sufficient for successful welding, after all, stainless steel has excellent weldability. I wonder if what I’m saying is correct?
First, confirm whether the welder’s certificate from the company includes welding stainless steel as one of the skills listed.
Wait for the expert’s reply! If they can eat 8 bowls of rice, can you eat 8 bowls too? The welding process differs slightly; when welding stainless steel, inert gas shielding is required, not only at the welding area but also at the areas that are heated.
First, confirm whether the welder’s certificate from the company includes welding stainless steel as one of the skills listed. I’m not sure what the value is of these devices of yours – how many do you have? I assume that your company’s welding engineers have taken into account the welding tasks performed by the welders, as well as the risks associated with the manufacturing process (such as the need for rework due to defective welds).
Theoretically, as long as there is a welding qualification for Fe IV and qualified PQR support, welding is possible. Ordinary 304 welding is quite common, with TIG welding or manual welding being the methods primarily used.
Can’t stainless steel be welded using submerged arc welding?
Can you guarantee product quality and control deformation?
A welder who has never welded stainless steel really can’t do it. Do you want to practice with products? Forget it; 507 is not easy to weld. Stainless steel is even more difficult to work with than 507
Yes. It can be welded. For welding, preparations include: 1) welding procedure qualification and welding procedure specifications; 2) obtaining the welder’s certificate by passing the relevant welding assessment tests.
As long as your company has support for weld procedure qualification and the welders have the appropriate welding qualifications, there will be no problem.
