Study on welding process of aluminum alloy supporting frameword

The welding process of aluminum alloy support framework was studied, combined with the support framework structure, weld form and technical requirements, from the process design, welding parameters, welding sequence, welding deformation control and other aspects of analysis and control. By adopting the assembly design without marking positioning, the welding groove depth optimization, the size process volume, the welding reverse deformation, the rigid fixing method and the static pressure adjustment method, the support skeleton sample is trialproduced, and the technical index is reached, which can provide technical reference for the manufacturing of similar aluminum truck products.
