Welding device and welding method for aluminum alloy thin-wall water-cooled container

Abstract

The invention discloses a welding device and a welding method for an aluminum alloy thin-wall water-cooled container, and relates to the field of welding tools. The welding device comprises a heat dissipation core rod and an end fixing plate, the heat dissipation core rod is of a step shaft structure and comprises a large end and a small end, the diameter of the large end is larger than that of the small end, a screw hole is formed in the center of the end of the small end, and the end fixing plate is fixed to the end of the small end through a bolt matched with the screw hole. According to the aluminum alloy water-cooling container welding device and the welding method using the device, the defects that a thin-wall thin-diameter aluminum alloy water-cooling container is poor in welding seam forming, the welding seam is not fused, and the number of welding seam air holes is large are overcome, and the welding quality and efficiency of the thin-wall thin-diameter aluminum alloy water-cooling container are improved.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a welding device and a welding method for an aluminum alloy water-cooled container. Background technique [0002] Thin-walled water-cooled containers refer to thin-walled water-cooled containers with a wall thickness not greater than 1.75mm and a diameter not greater than 104mm. When welding common aluminum alloy water-cooled containers, it is difficult to weld well with traditional manual argon arc welding or gas shielded welding. Low, when the current is slightly too large, because the diameter of the water-cooled container is small, the heat conduction of aluminum alloy is fast, and the distance between the arc starting position and the arc ending position is small. If the input is too large, the grain structure will be coarse or pores will be generated or even burn through directly, and the weld cannot meet the watertight requirements. If the current is too small, the partia...

Problems solved by technology

[0005] The second object of the present invention is to provide a welding method for aluminum alloy thin-walled water-cooled containers. By using the aforementioned welding device and improving the welding method, the welding speed can be increased to control the energy input of the welding line, and the transitional increase in the grain structure of the weld can be solved. Big problem, at the same time control the welding temperature field so that it can reach a dynamic balance
