Preheating in Welding Induction Heating Systems

Why Induction Heating?

Induction heating is a simple, cost-effective heating process that delivers fast and consistent heat in the following applications and industries: 

Applications

  • Preheating of welds and maintaining weld temperature
  • Post-weld heat treatment (PWHT) up to 1450° F
  • Hydrogen bake-out
  • Shrink-fit processes
  • Various other applications which requires heating

Industries

  • Shipyards
  • Oil and Gas
  • Mining
  • Structural
  • Power plants
  • Petrochemical/Refineries
  • Process/Power Piping
  • Pressure vessels

This highly efficient technology uses non-contact heating to induce heat electromagnetically rather than using a propane torch or resistant heating.  With induction, the part becomes its own heating element, heating from within.  This makes induction very efficient since little heat is lost in the process.
