Pipe Making Machine/Tube Mill use different welding methods to join metal strips of parent pipes (coils) and produce pipes. The following are some common welding methods for pipe making machines:

1. High frequency induction welding:

This is one of the most commonly used welding methods for pipe making machines. It uses a high-frequency induced current to heat the edges of a metal strip and then joins the edges together through pressure. This welding method is suitable for making many types of pipes, including welded steel pipes and stainless steel pipes.

2.TIG welding (argon arc welding):

TIG welding uses an inert gas (usually argon) to protect the welding area to prevent oxygen contamination. This welding method is commonly used in the production of stainless steel and aluminum alloy pipes.

3. Laser welding:

Laser welding uses a high-energy laser beam to melt and join the edges of metal strips together. This method can provide high-precision and high-quality welding, suitable for demanding applications such as aerospace and high-tech fields.

In conclusion:

Choosing the appropriate welding method often depends on the pipe specification, material, quality requirements and budget. Different welding methods have different characteristics and advantages, so it is necessary to choose the appropriate method according to specific needs. At the same time, tube mill/pipe making machine manufacturers usually provide corresponding welding method options according to customer requirements.
