Copper surface treatment process 2

4 Welding: Stainless steel parts must be carefully cleaned of oil, rust, dust and other debris before welding. When welding, argon arc welding should be used as much as possible. When using manual arc welding, small current and fast welding should be used to avoid swinging. It is strictly forbidden to start the arc in the non-welding area. The grounding wire is in proper position and connected firmly to avoid arc abrasion. Anti-splash measures (such as brushing white ash) should be taken during welding. After welding, use stainless steel (not carbon steel) flat shovel to thoroughly clean the slag and splash.

5 Multi-layer welding: When multi-layer welding, the interlayer slag must be cleaned. For multi-layer welding, the interlayer temperature should be controlled, generally not exceeding 60 ℃.
