Why Induction Preheating is Essential for Welding

Why Induction Preheating is Essential for Welding: Benefits and Techniques. Induction preheating is a process in which an electrically conductive material is heated by inducing an electrical current in it. The heat is produced by the resistance of the material to the current flow. Induction preheating is widely used in the welding industry for enhancing … Read more
