Low-cycle Fatigue of Post Weld Treated Butt Welds Made of High-strength Steels

Hrabowski, Jennifer; Herion, Stefan; Ummenhofer, Thomas

Abstract:
The low-cycle fatigue behaviour of butt welded plates made of S960QL, and S1100QL is presented in this paper. Specimens in as welded condition and post-weld treated specimens are considered as well as the influence of yield strength on the low-cycle fatigue behavior. Summarized evaluation and comparison with regard to different post weld treatment methods such as TIG-dressed, high frequency hammer peened and ground welds are worked out. The results are discussed referring to fatigue class classification of Eurocode 3 and the recent IIW guideline.
