Abstract

The invention provides an MIG (Metal-Inert Gas) and TIG (Tungsten Inert Gas) combined welding process for longitudinal seam welding of an aluminum material. A barrel body is involved; the surface A of the barrel body is an outer side surface, and the surface B is an inner side surface. The welding process comprises the following steps: I, milling a "V"-shaped outer groove in the surface A of the barrel body; II, performing dual-pulse bottoming by adopting MIG welding to form an automatic welding MIG bottom region at the middle part of the barrel body, and performing automatic electron argon arc welding on the outer side, wherein a welding wire is a DW-309L flux-cored wire, during welding, protective gas which is 100 percent of carbon dioxide is fed, and MIG and TIG synchronous welding regions are formed on the surface A of the barrel body; and III, completing self-fluxing of automatic welding TIG at one time, and forming an automatic welding remelting region on the surface B of the barrel body. The number of procedures of the novel process disclosed by the invention is reduced; on the basis of guaranteeing the welding quality, the production time is shortened, and the production efficiency is improved; and meanwhile, by the adoption of the combined automatic welding mode, the product welding quality can be fully guaranteed.

Description

technical field [0001] The invention relates to the technical field of aluminum material welding, in particular to a combined MIG and TIG welding process for longitudinal seam welding of aluminum materials. Background technique [0002] In the traditional aluminum manual welding process, such as figure 2 As shown, the main steps are: [0003] The first step: milling double "V" grooves on the inner and outer sides of the cylinder; [0004] Step 2: Carry out manual welding on the inner side of the cylinder, which are respectively bottoming, filling and covering; [0005] Step 3: Carry out manual welding root removal, self-melting, wire filling and covering on the outside of the cylinder. [0006] This traditional process has many steps, requires a long production time, and its efficiency is low. At the same time, the aesthetics of the welding area is not enough. Therefore, we propose a combined MIG and TIG welding process for aluminum longitudinal seam welding. . Content...
