Abstract
PURPOSE: To perform good welding by so radiating charged particle beams as not to assume an overhead state from the inner and outer sides of the welding works of hollow form in section which are fixed approximately horizontally.
CONSTITUTION: At the time of fixing the hollow welding works approximately horizontally and performing their beam welding, they are so positioned as not to assume an overhead state and their welding ends are lapped. More specifically, at the time of welding the welding works 1, 1 of circular section at their butt portions 2, their axial center is made the turning center of electron beam and the A portion from (a) up to (b) is inside-welded and the B portion from (c) up to (d) is outside- welded by moving the electron beam so that the weld ends of the inside and outside are lapped. In addition, the A1, A2 portions from (a) to (b) and from (c) to (d) are inside-welded and the outside surfaces of the B1, B2 portions from (e) to (f) and from (g) to (h) are up-welded. In the case of rectangular form in section, the lower part of the inside surface from (a) to (b) is flat-welded and the outside surface B1, B2 portions from (e) to (f) are up-welded, then the outside surface B3 portion from (g) to (h) is flat-welded. Thereby, the butt circumferential portions are surely welded.
