Induction Heating: Safer. Simpler. Faster.

Day in and day out, you work hard to complete heating jobs on time and on budget. While open flame and resistance are common go-to heating methods, they tend to complicate your schedule, stress your budget and create safety concerns. Thankfully, there's a better and safer option: induction. With an induction heating system, the metal part you're heating actually becomes its own heating element. Easy to set up, induction delivers exceptional accuracy and efficiency, faster time-to-temperature and true temperature uniformity across the workpiece.

Induction vs. Other Heating Methods

Induction Heating Flame Resistance
Reduce Injury EXCEPTIONAL
  • Only the part gets hot
 POOR
  • Open flame causes burns and exposure to toxic fumes
 POOR
  • Accidental touching can cause burns, broken pads can cause shocks
Reduce Labor GOOD
  • Fast setup/teardown
  • No operator required during heating process
 POOR
  • Operator required to handle torch
  • Often requires fire watch
 POOR
  • Slow and complex setup and teardown in many cases
Reduce Inefficiencies GOOD
  • Easy to self-perform
  • Heating efficient with utility use
 POOR
  • Most heat is wasted into the air
  • Inefficient with utility use
 POOR
  • Bad electrical power factor causes inefficient use of utility
  • A lot of heat wasted in the process
Reduce Time to Heat GOOD
  • Heat is generated within base material
  • Focused heat over the entire part speeds heating process
 POOR
  • Torch needs to be continually moved to heat entire part, resulting in slower heating speeds
 POOR
  • Heat is generated in the element instead of the part
  • Unfocused heat results in slower heating speeds

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.
