Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] figure 2 A schematic diagram of the welding position; Figure 4 The distribution diagram of the welding seams in the process of this embodiment is shown. After the welding process is improved, the new manual TIG welding process of the front and rear heads and the circular seam of the cylinder body is specifically:

[0021] a) Grinding the position of the weld seam before welding according to the requirements of the grinding process;

[0022] b) A gap of 2-3mm is reserved between the head and the cylinder body during spot-fixing, and the TIG welding method is used for spot-welding on the outside, and the length of the spot-welding seam is 20mm;

[0023] c) Turn the roller frame, as shown in Figure 2, adjust the welding position to the vertical upward welding position (PF), adopt the double-sided arc TIG welding method, the inner we...

Abstract

The invention relates to a welding technology of shell covers and a cylinder body of an aluminum alloy tank. The welding positions of the shell covers and the cylinder body are polished before welding; gaps are left between the shell covers and the cylinder body in advance, and then TIG is used for welding and fixing on the outer side; finally, the shell covers and the cylinder body adopt the two-side arc-alignment TIG for welding. The welding technology eliminates the situation that when a manual TIG welding method is used for welding the circular seams between the front shell cover and the cylinder body and between the back shell cover and the cylinder body, chain-shaped air hole welding defects exist at the longitudinal center positions of welding seams, the qualified welding seams canbe obtained, and the safety of a tank assembly is ensured.

Description

technical field [0001] The invention belongs to the field of aluminum alloy welding, and relates to a welding process for an aluminum alloy tank body head and cylinder body. Background technique [0002] The tank body assembly is an important part of the aluminum alloy oil truck and the aluminum alloy oil truck semi-trailer. figure 1 shown. Such as image 3 As shown, 1 is the head, 2 is the cylinder body, 3 is the inner side of the welding seam, 4 is the filler wire welding seam after root cleaning, and 5 is the cover surface. In the original welding process of tank head and cylinder body, the inner side is welded first, then the outer root is cleaned, and the outer side is filled and covered with welding. After welding with the above method, the weld cannot pass the radiographic inspection required by the design (radiographic inspection implementation standard is NB / T 47013.2, the transillumination grade is AB grade, and the rating standard is grade III), and the pass ra...
