Use an electric heating strip to handle it yourself!
Stainless steel is not necessary! Just control the welding process!
Stainless steel is susceptible to stress corrosion in media. Therefore, post-weld heat treatment (high-temperature solution treatment) is required to eliminate the chromium deficiency in the heat-affected zone after welding. :lol
