High frequency (HF) welding is a type of electric resistance welding in which metal strip edges are heated using induced current and then forged together during a roll forming process to create a continuous seam weld. The HF welding process relies on key process parameters such as welder power, frequency, precise heat input, raw material, and mill setup. With advancements in steelmaking, the process window for achieving a successful HF weld becomes smaller, making it important to closely control and monitor process parameters. This presentation summarizes the effects of HF welding parameters and mill setup and describes how to reduce costly scrap while achieving a better weld by optimization of process parameters.
