There are many ways to weld stainless steel pipes. The following are some common ways:
1. Welding butt girth seam: After the butt of two steel pipes, girth seam welding is performed, usually using TIG argon arc welding or MIG gas-shielded welding.
2. Weld the butt ends: After the two pipes are butt together, the ends are welded, usually using TIG argon arc welding or MIG gas-shielded welding.
3. Pipe cap welding: Welding a pipe cap on one end of the steel pipe, usually using TIG argon arc welding or MIG gas-shielded welding.
4. Induction welding: Induction heating technology is used to bring the inner wall surface of the stainless steel pipe to the welding temperature, and then pressure is applied to weld the two steel pipes together.
Common welding methods include circumferential seam welding, end welding, pipe cap welding, and induction welding.
