Abstract
A laser welding method for steel plates and a profile steel welded by laser welding are disclosed. The laser welding method comprises the following steps of connecting a first steel plate and a second steel plate to form a joint; and using a laser to weld the joint to form a profile steel. The laser has a laser power between 10,000 and 25,000 watts. A weld bead is formed at the joint. The weld bead has a weld depth and a weld width. The ratio of the weld depth to the weld width is between 1 and 5. Thus, the process can be simplified effectively, the welding time can be shortened, and the processing area can be reduced.
