Abstract

The hardness and the dimension of micron-grained steel welding joint were studied with different laser energy inputting. The macroscopical configuration, grain size, hardness, and impact toughness of micron-grained steel joint that was acquired by different weld techniques with different energy inputting were investigated and compared. The research shows the micron-grained steel welded by laser has great superiority.
