Better Pipe and Tube - T&H Lemont

In the HFI tube welding process, high frequency current is induced in the open seam tube by an induction coil located ahead of (upstream from) the weld point, as shown in Fig. 1-1. The tube edges are spaced apart when they go through the coil, forming an open vee whose apex is slightly ahead of the weld point. The coil does not contact the tube.(pipe) Boosting efficiency in solid state welders(steel) High-frequency induction (HFI) welding is used widely by the tube producing industry, but a large number of variables need to be controlled to perform the operation successfully.
