Abstract

The invention discloses a welding device and method for argon arc welding with a double-weld seam expansion support. A double-layer expansion structure is adopted. The lower expansion mechanism is provided with a long rod nut, and the long rod nut extends out of the upper expansion mechanism for operation. Control the opening and closing of the lower expansion mechanism; the upper expansion mechanism uses a hollow positioning shaft plus a layer opening and closing nut to control the opening and closing of the upper expansion mechanism. This setting can effectively separate the operation of the upper expansion mechanism and the lower expansion. heart agency. The invention solves the problem of assembling the welding assembly, makes the cylindrical part that is easily deformed into an elliptical ring rounded by expansion blocks, ensures fast assembly, greatly reduces the manual adjustment time, ensures fast welding assembly, convenient operation, and good welding quality , overcame the difficulty of welding, so that the cylindrical parts that were easy to deform into elliptical rings are rounded by expansion blocks, ensuring fast assembly, greatly reducing the time for manual adjustment, and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of engine component welding, and in particular relates to a welding device and a method for double-weld expansion core support argon arc welding. Background technique [0002] When welding the front shell of an engine, there are two circular welds that need to be welded, but there are many difficulties in welding. First, the welding parts are large thin-walled annular parts, and the cylindrical parts in the middle part belong to sheet metal. It is very easy to deform; second, the quality of the weld is relatively high, and the level is required to be Class II. X-ray inspection is required for flaw detection. It is required that the welding seam on the inner flow channel surface does not protrude from the surface of the base by more than 0.4 mm; Butt seam welding, but because the wall of the cylindrical part is thin, the shape is not controlled during welding, and it is easy to become elliptical, resulting in...
