The rapid development of design technology and strong marketcompetition have prompted us to look into the field of production of steel pipes with a process that perfectly meets industrial requirements, which is high frequency (HF) induction welding, which is the most common welding process to produce steel pipes. This process is currently better known for the manufacture of pipes of different diameters at the Tube Gaz unit in Tebessa (Algeria). Among the various known destructive tests, the Vickers hardness test is used to control the pipe. This test will allow us to determine the evolution of hardness in the longitudinal and transverse directions of the welded joint. The objective of our study is based on the characterization of the processes controlling the mechanical behavior of steel pipes (type S235) with a thickness of 2.2 mm and an outside diameter of 70.70 mm, welded by HF induction. The analysis shows the existence of very diverse microstructures in the studied welded joint. |
