Induction Heating Products You Can Count On to Get the Job Done

Day in and day out, you have been using open flame and resistance as your go-to heating method. But these tend to complicate your schedule, stress your budget and create safety concerns. There is a better option: induction heating. With an induction heating system, the metal part you’re heating becomes its own heating element. Easy to set up, induction delivers exceptional accuracy and efficiency, fast time-to-temperature with true temperature uniformity across the workpiece. That’s why now is the time to trade in your torches—and seize the upside of heating with induction.

Induction Heating On-Site

The company saw significant gains with the switch. Previously, welding a 48-inch pipe approximately 1 inch thick with a F3/F4 weld, passes took about 11 and half hours to complete (including flame preheating). With the change to wire processes and induction heating rather than open flame, that same weld takes five and a half hours to complete — a 52% increase in productivity.
