Example Embodiment

[0020] A CFA6470G front lower arm assembly welding process, which includes the following steps:

[0021] 1) First pick up the materials from the warehouse: front lower arm body, front lower arm liner, stabilizer bar bracket, A, B, C, D stiffeners, welding nuts, pipes and other parts, then go to the washing machine for cleaning, after cleaning Blow clean with an air gun to ensure that the parts are clean and free of oil.

[0022] 2) Install the front lower arm body, stabilizer bar bracket, A, B, C, D reinforcement ribs and welding nuts on the welding tooling for welding. The welding current is 160~180A, the voltage is 21~23V, and the KR350 model is used for welding. The machine performs spot welding on each welding part to ensure uniform spot welding and firm spot welding.

[0023] 3). Manually fully weld the spot-welded front lower arm body, stabilizer bar bracket, A, B, C, and D stiffeners. The welding current is 180-200A, and the voltage is 23-25V.

[0024] 4) Put the parts welded ...

Abstract

A CFA6470G front lower arm assembly welding process, which includes the following steps: 1) cleaning each accessory on a washing machine; 2) spot welding the stabilizer bar bracket, spot welding A, B, C, D reinforcement ribs and welding nuts ;3), all-welded stabilizer bar bracket, all-welded A, B, C, D reinforcement ribs; 4), drilled the φ46 hole on the parent body of the front lower arm; 5), spot-welded conduit, spot-welded reinforcing gasket and front lower Arm liner; 6), full welded conduit, spot welding reinforcement gasket and front lower arm liner; 7), boring φ36 hole and drilling φ18.8 hole on the front lower arm welding assembly, φ15.2 and 2‑ 12.7 holes; 8) Correct the opening size of the welding assembly of the front lower arm; the invention can effectively improve product precision, have good coaxiality at both ends, low production cost, strong applicability, and high production efficiency.

Description

technical field [0001] The invention relates to a welding process, in particular to a CFA6470G front lower arm assembly welding process. Background technique [0002] The front lower arm assembly is a part of the front suspension assembly of the automobile chassis. It is welded by several parts. Due to the high assembly size requirements, the total deformation required during welding is small, not greater than 1mm. The welding method is difficult to meet the technical requirements. Contents of the invention [0003] The purpose of the present invention is to provide a CFA6470G front and lower arm assembly welding process, which can effectively improve product quality, have good coaxiality of the holes at both ends, low production cost, strong applicability and high production efficiency. [0004] The technical solution of the present invention is: a CFA6470G front lower arm assembly welding process, characterized in that it comprises the following steps: [0005] 1) Clea...
