What are the defects of welding quality of pipe welding machine?

1. Cracks

The reasons for the cracks are very complicated, and the following analyses are made from the aspects of raw materials, forming, and process parameters.

Raw material: There are deviations in the composition of the strip, and there are cracks, interlayers in the strip, uneven strip width, large thickness changes, uneven edges, excessive burrs, and burrs outward during forming.
