Straightening with induction heating

Our deck and bulkhead straightening solutions are found in the ship- building industry (deck straightening), construction industry (straightening of bridges) and trains/trucks industry (production and repair of locomotives, rolling stock and Heavy Goods Vehicles).  


Using induction for straightening means that you get the right heat, exactly where you want it. When repairing a steel chassis on a truck, for example, there’s no need to dismount heat-sensitive components such as brakes and cables.   Induction also makes life easier for staff and the environment. No gas flame to emit dangerous fumes. No flame to burn the skin. And, in addition, induction heating is easy to learn and safe to use.

Terac has been documented to cut straightening times by as much as 80 per cent compared to flame heating and other traditional methods.


EFD Induction Teracs can be found in shipyards around the world. Customers usually cite a dramatic reduction in straightening costs as the biggest benefit of switching to Terac.



The Terac 25 brings the cost, safety and environmental benefits of induction heating to shipyards. A proven, turnkey solution, the Terac only needs an electricity supply and it’s ready to start work. Terac is ideal for deck and bulkhead straightening.

Induction straightening

Induction straightening in the shipbuilding industry

EFD Induction equipment can be found in shipyards and dry docks around the world. In fact, it was EFD Induction who back in the early 1980s introduced induction straightening as the ultimate solution.


What is it then that makes induction so attractive for straightening assemblies that have been distorted by welding on a ship? One reason is precision—you get just the right temperature, just where it’s needed. The risk of overheating metals is much less than with a flame. In fact, it is impossible when heating magnetic steel.


Another reason is that induction generates heat directly in the material. You considerably reduce the risk of fire—crucial when working with straightening decks or bulkheads inside the ship. In addition, it’s easy to learn how to handle induction heating. Savings in working time can amount to 80 percent and energy efficiency is also greatly improved.

Induction straightening in the automotive industry

Our induction straightening solutions for the automotive industry focus on truck making and repair. Our mobile Minac system is especially suited to the latter, as it allows easy access to hard-to-reach parts, allowing rapid, concentrated heating of damaged profiles and chassis rails.


Induction straightening with EFD Induction equipment is superior in several key ways to traditional gas flame methods:

  • Induction heat delivery is accurate; only the workpiece itself is heated
  • The rapid, accurate heat results in high levels of shrinkage
  • Induction minimizes the risk of heat damage to surrounding cables, hoses, metals, etc.
  • Induction is safe, controllable, easy-to-use and environment friendly
Induction heating cuts deck and bulkhead straightening times by as much as 80 per cent compared to alternative methods.
