Hardening of slewing rings
Wind is the ideal energy source. It’s safe, it’s clean, and there’s an endless supply. But harvesting and converting it into electricity poses challenges. The large slewing bearings used in wind turbines, for example, are subject to extreme loads and near-constant operation. Such conditions mean the slewing rings must be hardened without producing so-called ‘soft spots’ or ‘soft zones’. These zones are caused by unintentionally heating already hardened areas—in effect tempering, or softening, the metal.

Induction hardening of camshaft lobes

EFD Induction is the world’s no.1 induction hardening company. That’s good news for us. But what’s more important is why?


One key factor is our proven success at ‘package hardening’—the simultaneous hardening of three closely spaced camshaft lobes.

Change from gas or arch heating to induction heating
One small but important step to help the environment is the change from gas or arc heating to induction heating.

EFD Induction expands into Canada and Romania
EFD Induction recently acquired 49% of Tekna Plasma Systems, Inc. The Quebec-based company develops and manufactures equipment that uses induction plasma technology in many areas. And Tekna is always on the lookout for novel ways to apply induction plasma technology, a quality we value.

Induction heating for the aerospace industry
Specialized applications. Stringent quality levels. Tight leadtimes. The global aerospace industry sets tough demands on its parts and equipment suppliers. But they are the kind of demands that induction technology is uniquely qualified to satisfy.

Coating of brake disc
What do more and more leading auto makers (including BMW, Audi and Volvo) have in common? They’ve all selected EFD Induction to heat treat brake discs against corrosion.

Seam Annealing with Horizontal Tracking
When producing welded pipes according to API specification or similar, the weld and the heat affected zone (HAZ) have to be normalized. EFD Induction has three solutions.

Heating of rivets
Every service call is unique. However, we received one recently that was truly extraordinary. Tom Smith, machinist for the 1925 steamship ‘Saltsjön’, rang. Could we help restore the old vessel by heating rivets for new, below-deck flooring?
