High-Frequency Induction Welding
A continuous process for tube manufacturing where induction coils introduce high-frequency currents into slit-tube edges to bring them to welding heat prior to pressure rolls.
In high-frequency induction welding, you heat the edges of the pipe slot without contact via an induction coil. The current flows directly in the workpiece and generates the necessary heat there until the steel melts and the edges are welded together under pressure. This process is well suited for thin-walled pipes and produces clean, tight seams. If you don't set the frequency or power properly, the heat becomes uneven, and you get cracks or deformations. Make sure the coil sits exactly and the process runs stable, then the seam will be uniform and crack-free.
