Induction heating

The Lincoln Electric Company is set to launch its first ever induction heating equipment, the Thermal Wave®, in January of 2026. Prior to launch, a technical program was piloted with Lincoln Electric’s Application Engineering department to gain a thorough understanding of how induction heating can be deployed into three common industries: power generation, transmission pipelines, and structural welding.

To do so, three welding experiments were conducted to be representative of a power generation application governed by the requirements of ASME IX and ASME B31.1, a transmission pipeline application governed by the requirements of API 1104, and a structural application governed by the requirements of AWS D1.1. The program studied and documented practical uses of induction heating and provides guidance to optimize setup and operation of induction heating systems for preheat, interpass maintenance, and post weld heat treatment.
