| Abstract: | In order to enhance the fatigue life of the metal structure,the stress amplitude theory has been adopted.This paper introduces the structure detail and structure form of the welding structural piece,the welding form and structural technique.It proves the influence of the welding joint detailed structure to the fatigue strength of the welding piece and puts forward a few improving measures,which shows fine anti-fatigue performance in the welding seam of large metal structural piece and the whole structural piece,and has got good results. |
