Metal welding structural strength was affected by the quality of automobile welding structure. Many accidents of the machines are caused by welding defects of automobile structure. Many welding parts are applied in the automobile. Reliability of automobile welding structure is studied and discussed in this paper. Failure modes and ultimate strength of automobile welding structure are obtained with bench test. The results show that all the failures happen in the welded region between clutch hub and clutch hub axle. Finite element model is built, and automobile welding structural strength is analyzed. And simulation results are in line with that of the experiment. Based on stress and strength interference model, automobile welding structure reliability is studied and discussed with theory of probability and reliability. In accordance with matching working load with structural strength, a new method of improvement design is proposed with the aim of automobile welding structural strength reliability. It provides a theoretical basis for automobile welding structure improvement design. And similar methods can be used to develop automobile welding structure and laser welding processes in future.
