Induction heating-assisted laser welding of stainless cylindrical pipes

A 3D model of induction-assisted laser welding of stainless cylindrical pipes is presented, incorporating two physical fields: magnetic field and temperature field in the welded pipe that influence one another. The model is solved in quasi-coupled formulation using software COMSOL Multiphysics&#x...
