  • Better Pipe and Tube - TH Lemont

    High Frequency Induction Welding. 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.

  • Flower Strip Width - JMC Rollmasters

    Tube roll design begins with the selection of the most appropriate breakdown roll forming type for the application. Then a sequence of shapes representing the desired amount of bending at each mill station is developed. When we stack these shapes on top of each other they look like a flower. Hence the term, "Forming Flower".
