Abstract
The safety of deepwater or large offshore structures is distinctly important than ship and other ordinary marine structures. Welded steel structures have high crack risk,especially fatigue cracks.In some cases,except good design and additional quality requirements,it is a good solution that uses manufacturing process to improve weld detail fatigue strength.Based on some offshore codes and engineering practice,this paper introduce some usual weld detail fatigue strength improvement methods,including weld profiling by machining and grinding,Weld toe grinding,TIC dressing,Hammer peening.sum up some practical process details and matters need attention.At last of this paper discuses some problems need solving, and analyze the application prospect forecast of weld detail fatigue strength improvement technique in offshore engineering.关键词
