Article Preview

The application of fracture mechanics is being increased gradually to assess the safety of welding crack-containing structures. The joint parts of vehicle frame are mostly made up of welding joint. Due to the impact and fatigue load, cracks initiate and propagate in the welding joint part, as a result, the frame comes to a final failure. Therefore it is necessary to improve the welding performance and fracture resistance of welding part in structure. This study presents a most suitable way of welding process for lap joints by CO2 arc welding which is widely used in the the vehicle structure. Also this paper makes an evaluation to tensile strength and fatigue strength under various welding condition
