Conventionally, in this type of automatic electron beam welding control device, one method is to take advantage of the fact that the electron beam of a given electron beam welding machine can be arbitrarily deflected to perform a welding process according to a prespecified shape. Welding is in practical use. Also, recently, due to advances in sensing technology, a control method has been adopted in which the joint position is detected by a sensor during welding and the electron beam deflection amount is corrected.

In the above-mentioned conventional electron beam automatic welding control device, in the former case, absolute positioning of the welded object is required, so if the welded object has a complicated shape, a control program is required. The disadvantage is that it is extremely complicated. In the latter case, the positioning is simplified and a program to follow changes in the shape of the workpiece is not required, or, although it is extremely simple, the positioning is simplified and the joint is simultaneously welded. It is not possible to avoid errors due to feedback delays caused by the method of position detection, and there is also a drawback that accurate welding cannot be performed because the welded part emits light and its shape changes.
