摘要： A gap is provided at joining faces of a pair of metal works with an uneven shape when the metal works contact one another for joining. An adhesive agent having a chain-reacting curing reaction function is disposed within the gap. The adhesive agent is cured by an autogenously-generated curing reaction heat caused by an outer energy and an additional heat that is successively generated by the autogenously-generated curing reaction heat within the adhesive agent. A welding portion, where the works contact one another substantially directly, is welded by a laser beam, and the above-described energy for causing the autogenously-generated curing reaction heat for the adhesive agent is provided by the laser beam. Accordingly, a joining structure and method of metal works that can have less limitation in a joining location is provided.

摘要： A laser welding method including a step of welding upper and lower metal plates, a step of picking up an image of a molten pool near a molten hole from the side of the upper metal plate during an execution of the welding step, a step of determining whether a welding state of the metal plates is proper or not by analyzing a generation state of the molten pool based on the image picked up in the picking-up step, and a step of adjusting at least one of a parameter of the irradiated laser beams and a feeding speed of the filler wire so that the welding state of the metal plates becomes proper in case the welding state determined in the determining step is not proper.
