Fusion45: New Rugged Induction Heater Improves Weld Quality

Welding Induction Heater
New Welding Induction Heater
Heat treating isn’t done in a laboratory, or a clean room. Applications are out in the real world, where dirt, grease and grime are normal. Hotfoil’s new induction heater is designed to work in the toughest conditions, and continue to run shift after shift.

Induction heating works very quickly, and since there is no contact with the target piece, there are far less concerns about part contamination. Many industrial processes use induction heating when very high temperatures and uniform control is desired.

Pre and post-weld heat treating (stress relieving) is a growing market for induction heating systems because it offers significant benefits such as excellent heat placement and distribution, lower cycle times, safety, ease of use, and efficiency.

Induction heating can improve your bottom line by decreasing weld failures, and decreasing setup and tear down times. The technology allows for accurate temp control, without heavy electrical service or complicated controls. The portability and ease of use will allow you to heat more welds faster.

Important Event: Canweld Expo

On October 4th and 5th Canada's largest welding, fabricating, and metal finishing conference is taking place in Edmonton, Alberta.

The CanWeld Expo is described as "the only Canadian-made major exhibition dedicated to welding, metal fabricating and finishing. Held in partnership with the Canadian Welding Bureau’s award-winning CanWeld Conference, this annual event will visit the centre of Alberta’s manufacturing heartland – Edmonton. This location also aims to service the region’s active oil & gas, petrochemical, agriculture and general manufacturing supply chains."

Hofoil-EHS will in exhibiting as a guest of Stein Industries in London, Ontario. Stein will be exhibiting its high quality, custom designed, affordable induction heaters built to withstand harsh environments with wide applications.

This is a great opportunity to see major welding equipment vendors and new technologies being introduced. If you plan on being at CanWeld, please stop by the Stein Industries at booth 820 in the Main Hall.

Diagram of Equipment for Typical Weld Heat Treating

Weld preheating involves heating a section of, or the entire part, to a specific desired temperature, generally referred to as the preheat temperature.

The heating may or may not continue during welding, dependent on the heat generated by the arc. The goal is to maintain a certain temperature from the first weld pass to the last.

Preheating produce several very beneficial effects, including producing a more ductile metallurgical structure that cracks less, helps in releasing trapped hydrogen, and reduces stress cracking during cooling.

It is always recommended that you should consult with weld heating experts and learn the fundamentals of this process in order to avoid costly errors in preparation or wasting money on the using the wrong equipment.



Here is a very general diagram of the typical welding pre-heat equipment layout.
