ABSTRACT:
Conventional beam-welding methods have disadvantages in that the total energy efficiency is low and that the bonding zone and HAZ spread due to indirect heating of the weld zone. In the present invention, a wedge-shaped space is formed between the non-contact parts of the articles, and an energy beam, such as a laser beam, an ion beam, and a plasma arc, is projected into the wedge-shaped space so as to heat the weld zone or the parts of articles which will later be joined. The controlling apparatus of the present invention controls the power of, for example, a laser beam based on the detecting of travelling speed of sheets and the like.
