Dec. 09, 2017

Welding crack is the most common type of weld defects. The weld crack of Spiral Steel Pipe production is affected by the chemical composition of welding raw material, internal welding spot location, eccentric center and so on. For the production of welding crack, analyzes the welding crack property, raw materials, process and forming process. The suitable welding wire and flux matching are selected for different materials. The welding spot position, partial center and the welding process parameters are fine and accurate in the welding. At the same time, we should improve the quality of steel tube forming, reduce he resilience of steel tube, and strictly control the process parameters in production.
