FATIGUE BEHAVIOURS OF FRICTION WELDED DRILL PIPES

16677

The drilling pipes are used under the different load in the service condition. In this study, N80-N80 similar drill pipes and N80-42CrMo4, N80-S355J2 dissimilar steel pipes were welded with friction welding process. The fatigue behavior of welded samples was investigated and the results were interpreted by considering the hardness values and tensile strength. It was found that the fatigue behaviour of friction welded samples recovered by the increasing tensile strength and hardness.
