Background Art

Its main purpose is to weld the workpiece and ensure the welding quality. Usually, the grooves cut on pipe fittings have sharp edges, which can easily cut workers during welding. If the outer and inner sides of the part to be welded near the groove of the pipe fittings are not polished, the dirt on the outer and inner sides of the pipe fittings will dissolve into the welding position, resulting in the problem of reduced welding quality.
