How to learn second welding?

Double-sided shielded welding (full name carbon dioxide gas shielded welding) process is suitable for welding various large steel structures of low carbon steel and low alloy high strength steel. High welding productivity, good crack resistance, small welding deformation and wide deformation range, which can be used to weld thin and medium plates.

Whether the secondary welding can be welded well depends on the cooperation of current and voltage, which can make the weld smooth, beautiful and high strength.
