Resistance Heating Mats for Welding Pre and Post Heat Treatment

Ceramic Mat Heater
Resistance heating mats (or pads) are constructed of ceramic beads strung on nichrome or Kanthol wire. These resistance heating elements accurately heat the workpiece to the proper temperature before, during, and after welding, assuring compliance with recommended preheat, interpass, and PWHT practices. Designed as semi-flexible ceramic heater pads, with interlocking beads and high temperature wire, so a proper fit to the workpiece. Capable of temperatures up to 1,850 degrees F., ceramic mat (pad) heaters have an additional benefit in that they can withstand welding temperatures and don’t have to be moved during welding.
