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
Induction Preheating Before Welding For Stress Relieving Heater Why use Induction Preheating Before Welding ?Induction preheating can slow down the cooling rate after welding. It is beneficial to escape the diffused hydrogen in the weld metal and avoid hydrogen-induced cracks. At the same time, It also reduces the welding seal and heat-affected zone hardening level, … Read more
Induction Preheating Before Welding Steel Pipe This induction heating application shows the preheating of steel pipe before welding with 30kW air-cooled induction power supply and air-cooled coil. Inductively preheating of the pipe section to be welded ensures faster welding time and a better quality of the welding joint. Industry: Manufacturing Equipment: HLQ 30kw air cooled … Read more
