Several methods to solve the cracks in gas shielded welding
The reason: Slotting Angle is too small, resulting in pear shape and weld bead cracks during high current welding. Preventive measures: Pay attention to the appropriate grooving Angle and current match, if necessary to increase the grooving Angle. The reason: Excessive carbon and other alloys in the base metal (weld pass and thermal shadow zone).…
