Welding Process in roll forming machine: Welded profile applications increasing over the last 10 to 15 years, driven mainly by the automotive industry.
though many welding technologies use on tube and pipe mills, three have come to the front:
1.tungsten inert gas (TIG) such as gas tungsten arc welding (GTAW)
2. laser beam welding (LBW)
3.high-frequency induction (HFI) such as resistance seam welding (RSEW-I).
These Welded technologies can divide into two groups, fusion welding and forge welding. GTAW and laser are fusion welding technologies and HFI is a forge welding technology.
