<p>Structures such as a conventional heat exchanger, a truss, or the like which are formed through conventional friction stir welding or arc welding in the conventional invention are welded by using an electromagnetic purse in accordance with the characteristic of a junction material and the like. According to the present invention, reliability may be more improved than when conventional friction stir welding or arc welding is performed, while saving the time required to form a structure. Moreover, the failure rate can be reduced by hand to significantly increase productivity.</p> |
