Spiral steel pipe welding area common defects

Spiral welded pipe is a major transmission fluid welded steel pipe, spiral welded pipe production by a coil of width continuous molding welding is easy to implement production automation, and double-sided submerged arc welding automatic welding type, there are a variety of The testing method checks checks to ensure the quality of the welds, laying oil and gas pipelines, has been widely applied to the spiral welded pipe.

Special Welded Tubes

But in forming the welding process, due to operational mistakes or process due to mature etc., lead to the the welded pipe produces a wide variety of defects.

Spiral steel pipe welding area common defects porosity, hot cracking and undercut.
