When welding stainless steel pipes, you need to pay attention to the following points:
1. Clean the surface of the stainless steel pipe: Before welding stainless steel pipes, you must ensure that the surface of the steel pipe is clean, oil-free, dust-free, and oxide-free.
2. Choose suitable welding materials: In general, the welding material should be the same stainless steel material as the steel pipe to ensure the stability and firmness of the welding point.
3. Control the heat input: During the welding of stainless steel pipes, it is necessary to control parameters such as voltage level, current intensity, welding rate, and electrode diameter to control the heat input.
4. Avoid excessive welding: Excessive welding will cause deformation of the steel pipe, generate stress, and affect the quality of the weld. When welding stainless steel pipes, excessive welding should be avoided to minimize excess welds.
5. Use appropriate welding methods: Different welding methods have different applicable conditions. When welding stainless steel pipes, appropriate welding methods should be selected according to actual needs, such as TIG welding, MIG welding, or manual arc welding.
6. Do a good job of post-weld treatment: After welding, the stainless steel pipe needs to be treated with subsequent treatment, such as heat treatment, annealing, polishing, etc., to ensure the durability of the welding results.
