Numerical Simulation and Experiment Analysis of MIG Welding for Aluminum Alloy Extrusion

摘要：

　　Welding characteristics of MIG welding for aluminum alloy extrusions are studied.In this article,the aluminum alloy is EN AW-6005A.The welding heat source and the welding processing of aluminum alloy extrusions are discussed.A three dimensional finite element model has been developed to dynamically simulate the welding process.The investigations focus on the comparison the welding heat resource of simulation and section of the experiments parts.And the residual stress of numerical simulation and tests are compared.Its help to optimize the MIG welding processes and improve the welding quality for aluminum alloy extrusion.

关键词： Numerical simulation of welding process FEM Heat source Residual stress
