FAQ

When welding steel workpieces with MIG/MAG gas protection (GMAW) and flux cored wire gas shielded welding (FCAW), how will it be treated if the plate thickness of the workpiece exceeds the maximum welding current that the welder can reach?


The solution is to preheat the metal before welding. Propane, standard gas or acetylene welding torch is used to preheat the welding area of the workpiece, and the preheating temperature is 150~260 °C, and then welded. The purpose of preheating the weld area metal is to prevent the weld area from cooling too quickly and not causing the weld to crack or not fuse.
