(1) The weld has high crack resistance. The weld is low in hydrogen and contains less nitrogen.

(2)Less deformation after welding. The angular deformation is five thousandths, and the unevenness is only three thousandths.

(3)The welding splash is small. Reduce the weld spatter when using ultra-low carbon alloy wire or flux cored wire, or by adding Ar to CO2
