Abstract
A steel plate assembly welded by laser welding and a laser welding method thereof are disclosed. The steel plate assembly comprises two steel plates and a molten region. The steel plates are joined. A joint face of the steel plates extends along a joint line. The molten region extends along the joint line. The molten region has a molten depth of between 20 and 50 mm. The molten region has a molten width of between 4 and 7 mm. The molten region is formed by welding the joint face using a laser. After the molten region is cooled and solidified, the steel plates are combined with each other. The molten depth is 20 to 50 millimeters, so the laser welding method is applicable to thicker steel plates.
