Induction Heating

Induction heat treatment equipment has greatly improved the speed and ease of the heating of large scale metal pieces for construction, weld preheating/post-heating and the maintenance of industrial equipment.  Red-D-Arc has become known for our expertise in the application of induction heat using induction heat blankets, coils and ovens in a diverse variety of applications.

Induction Heating with Submerged Arc Welding

When one of our customers was tasked with an electrical motor shaft rebuild that required them to weld new fins onto a 7” diameter shaft, they called on Red-D-Arc’s team of experts for assistance. The job required the shaft to be preheated to a temperature of 400°F and welded using a submerged-arc process (SAW). Using the Miller Proheat 35 and Lincoln’s LT7 sub arc package, a job that was originally bid at 40 hours took just 3 hours to complete.

This innovative solution saved our customer a substantial amount of time and money.  Our customer was able to keep a project —which would normally be outsourced— in house.  As an added benefit, they now have a new service they can promote to their customers.

Preheating Applications in Welding

Importance of Preheating in Welding – Equipment Options

Preheating pipe for welding

Why preheat?

Preheating reduces the risk of cracking in weld metal and heat-affected zone (HAZ) by:

  • Lowering the cooling rate of the weld – prevents formation of brittle weld metal/HAZ, allows more time for hydrogen to escape the molten weld.
  • Removing moisture (hydrogen source) from the part.
  • Reducing shrinkage by lowering the temperature differential.

Preheat or not?

The requirement and level of preheating for steel is determined by the relevant welding code and is dependent on the weld heat input, chemical composition of steel (carbon equivalent), thicknesses, diffusible hydrogen etc. Non-ferrous materials generally require preheat because of their high thermal conductivity.

Induction Heating Speeds up Repair of the World’s Largest Rock Crusher

Red-D-Arc staff at the Moncton, New Brunswick branch recently helped a customer save time and money repairing the world’s largest rock crusher through the use of induction heat. The hydraulic cylinder that operates the pressure plates used by the enormous rock crusher needed to be brought to a temperature of 500 °F and that temperature needed to be maintained for 3 full days. This was required in order to allow welders to repair the lifting tabs on the cylinder. Normally 3 workers would have used blow torches to heat the metal which would have taken 2 weeks or longer. Red-D-Arc Induction Heating Equipment allowed them to get the job done in less than half the time. Induction heating has many applications in construction, shipbuilding, hydro dam maintenance and bridge building. Red-D-Arc technicians are recognized in the industry for their innovative application of this technology, ready to meet any variety of customer challenges.
