摘要：

This paper has mainly concentrated on the abutting joints corner joints and lap joints of TCS stainless steel, which are produced by TaiYuan steel plant. It has used group method and fluctuation method to test the fatigue limits and p-S-N curves under 95 percent degrees of confidence and 90 and 50 percent degrees of fraction surviving of the six types of joints. These will give technique assurance and data support to welding bogie design. It has also used scanning electronic microscope to observe the typical specimen. The fatigue source and cracking reason of the specimen which will provide reference for welding methods for increasing fatigue strength of such welded joints and establishing the welding procedure were analyzed. The research in this paper will provide basic data for the applications of TCS stainless steel in new heavy load wagons.
