The guide die is very important for stainless steel pipe welding machine or high-frequency pipe welding machine. If the design of the guide die is unreasonable, the steel strip will have undercut and overlap defects during welding, and the welded pipe will not meet the standard.

The guide molds of stainless steel pipe welding machine are generally 3 pairs, belonging to the precision forming part. Sometimes there are 4 groups of layout design. Sometimes when producing small thick pipes, the most group of guide molds will be designed in the form of circular arc, and the spacer in the middle is canceled, which is to better align the edge of the steel strip.

The important role of the guide die of the stainless steel pipe welding machine is to control the pipe forming steps and the size of the opening angle through the middle spacer to ensure the welding effect.
