Abstract
PURPOSE:To reduce the welding cost and to improve the welding quality by tack-welding long-sized side plates without making edge preparation and then carrying an article to be tack-welded into a vacuum chamber and welding a diaphragm and weldlines on the side plates by an electron beam. CONSTITUTION:An airtight pressure box 1 is provided and connected by suction ducts 22 with a vacuum pump chamber 21. A truck 15 for mounting the article 14 to be welded is provided movably on a rail 13 in the box 1. The long-sized side plates 29-31 are tack-welded without making edge preparation to arrange patches 33, 34. This long-sized weldment 14 is loaded on the truck 15, the inside of the box 1 is kept at a high vacuum and then, the diaphragm 28 and the side plates and the weldlines of the side plates 29-31 are electron-beam-welded by an electron gun 7. Since all of the weldlines are electron-beam-welded, heat necessary for welding is small and the material cost necessary for welding is reduced. Therefore, the welding cost is reduced and the welding quality is improved.
