Abstract
A thick steel plate assembly welded by laser welding and a laser welding method thereof are disclosed. The thick steel plate assembly comprises two steel plates and a filler region. A joint face of the steel plates extends along a joint line. At least one portion of the joint face of one of the thick plate steels is formed with a groove along a grooving line. The filler region is formed by feeding a filler into the groove and using a laser to weld the joint face having the groove through the filler. After the filler region is cooled and solidified, the thick steel plates are combined with each other. A thickness of each filler layer in the filler region is between 4 and 6 mm. Thus, the process can be simplified greatly and the cost can be reduced.
