High Frequency Induction (HFI) Welded Pipe - Sunny SteelIn High Frequency Induction (HFI) Welded Pipe production process, hot rolled steel coils are fed with a high capacity accumulator in order to achieve continuous welding. HIGH-FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating.

What is induction welding?

The speed and accuracy of induction welding makes it ideal for edge welding of tubes and pipes. In this process, pipes pass an induction coil at high speed. As they do so, their edges are heated, then squeezed together to form a longitudinal weld seam. Induction welding is particularly suitable for high-volume production.See all results for this questionWhat is high frequency induction welding?High frequency induction welding is used to make pipe or tube from strip which is fed into rolls which form the strip into a cylindrical shape.See all results for this questionWhat is high frequency (HF) induction welding? - TWIHigh frequency induction welding is used to make pipe or tube from strip which is fed into rolls which form the strip into a cylindrical shape. The faying edges are brought together between squeeze rolls to produce a V at the point of welding, with an included angle of typically 2-5° for steel. A high frequency coil introduces current into the tube ahead of the squeeze rolls.
