Through induction heating Topp’s Mechanical has found a solution that meets and exceeds the quality standards of its heat treatment applications while also providing strong operational benefits, including faster time-to-temperature, consistent heating throughout the entire part, easier to apply/wrap heat, greater reliability and lower consumable costs, more efficient use of labor, and improved safety for employees.
An overview of the work performed by Topp's Mechanical and its work with induction heating technology.
Topp's Mechanical's Eric McDonald discusses the ease-of-use of Miller's ProHeat 35.
With an induction heating system, heat is created electromagnetically in the pipe wall rather than by surface heating, as is done with an open flame or resistance heating. Topp's Mechanical uses Miller's ProHeat 35 Induction Heating System.
After bringing the header up to temperature, welders place a TIG root in the o-let.
Topp's Mechanical has built custom jigs that allow for the header to be set right on top of the induction cables. This helps heat the piece from the bottom and minimize wrapping time.
Once the TIG root is placed, welders switch to a gas-shielded Flux-Cored wire before eventually switching to sub-arc welding.
Maintaining temperatures is key, which is much easier and more efficient to do with induction heating compared to propane heating.
