| Abstract: | On the basis of the process of development and production of stainless steel carbodies, the fatigue mechanism of spot welding and arc welding weld that are the most critical in fatigue is analyzed. The fatigue evaluation methods for spot welding and arc welding weld in the relevant standards abroad are compared and analyzed. And the evaluation of specific joint types is expounded according to the standard. |
