Abstract

The invention discloses a welding tooling support for carbon dioxide arc welding. The welding tooling support comprises a base and an adjusting device for adjusting a welding torch, wherein one end of the adjusting device is fixed on the base, and the other end of the adjusting device is connected with the welding torch. The invention further discloses a welding method in which the welding tooling support is utilized. The welding method comprises step 1 adjusting the position of the welding tooling support, positioning the welding torch, and adjusting an angle formed by the welding torch and a product to be welded; step 2 preheating the product; step 3 subjecting the product to surfacing; and step 4 subjecting welding seams formed by surfacing to hydrogen relief heat treatment and dye penetrant inspection. The welding tooling support for carbon dioxide arc welding reduces labor intensity of welders and improves welding quality and production efficiency. According to the welding method, short time is required, continuous welding is achieved, time of replacing welding electrodes is decreased, and welding cycle is shortened.

Description

technical field [0001] The invention relates to a welding tool frame, in particular to a welding tool frame for carbon dioxide gas shielded welding and a welding method thereof. Background technique [0002] Surfacing anti-corrosion layer on the inner wall of chemical container cylinder is a special process method in the manufacturing process of large chemical container. For example, the 560-ton hydrocracking reactor manufactured by Shanghai Boiler Factory is one of them. This product is the core equipment of the 800,000-ton / year hydrocracking unit of Zhenhai Petrochemical General Plant. The three types of pressure vessels with the heaviest parts are one of the major national technical equipment projects. Stainless steel stacking is required for the joints of the inner surface of the container, the cylinder and the cylinder, the cylinder and the head, the cylinder and the connecting pipe after welding, the end face of the connecting pipe, the sealing surface of the flange c...
