Project description

In this project friction welding technology will be optimised for production of girth welds for long (18m) pieces of pipelines. The welds will be realised between two stationary pipe ends and a rotating weld ring in between. Different welding parameters (rotation speed, friction pressure, forgeing pressure, geometry of intermediate ring, heat balance) will thoroughly be investigated in order to obatin otimal weld quality. Welds will be characterised by means of traditional mechanical testing (tesile test, Sharpy test)
