Dual Induction and Contact Welders

With the ever increasing energy costs worldwide, more large diameter pipe producers have been selecting Thermatool’s Solid State Dual Induction Welders. This provides the producer the knowledge of significant power cost savings upon welding larger diameters, with this more efficient process. Thermatool, the inventor of the HF contact welding process, has met the evolving requirements of API pipe production with Solid State Dual Induction Welders. With recent advances in power supply design, Thermatool has combined the best of both welding processes into one system.
