The joint parts' of bus frame are mostly made up of welding joint. By the impact and fatigue load, cracks initiate in the welding joint part, thus the frame come to final failure. So, it is necessary to improve the welding performance and fracture resistance of welding part in structure. In this study, the constant load fatigue test was carried out about the bus underbody frame, and it was studied how the fatigue life was affected by the influence of the plug welding method and dimensions.<br/> <br/>
