Straightening with induction heating

Induction straightening

Our time-saving deck and bulkhead straightening solutions are found in the shipbuilding industry (deck straightening), construction industry (straightening of bridges) and trains/trucks industry (production and repair of locomotives, rolling stock and heavy goods vehicles).

What is induction straightening?

Induction straightening uses a coil to generate localized heat in pre-defined heating zones. As these zones cool, they contract, "pulling" the metal into a flatter condition. 


What are the benefits?

Induction straightening is extremely fast. When straightening ship decks and bulkheads, our customers often report minimum 50% time savings compared to traditional methods. Without induction, straightening on a large vessel can easily consume tens of thousands of man-hours. The precision of induction also boosts productivity. For example, when straightening truck chassis, there is no need to remove heat-sensitive components. Induction is so precise it leaves adjacent materials unaffected.  

Where is it used?

Induction heating is widely used to straighten ship decks and bulkheads. In the construction industry it straightens beams. Induction straightening is increas-ingly used in the manufacture and repair of locomotives, rolling stock and heavy goods vehicles.

Straightening with induction heating

Induction heating is widely used to straighten ship decks and bulkheads.

An EFD Induction Terac system ensures failsafe operation—it makes it impossible to overheat magnetic steel.

Induction heating for bulkhead straightening

Terac works just as well on bulkheads and other vertical structures as it does on decks.

For added ergonomic comfort, the handheld transformercan be attached to a balancer and suspended from a magnet or wire rope.

Operators can work with Terac within a 45m radius of the base unit. An optional extension unit lengthens the work area to a 60m radius.

EFD Induction Terac systems are specially designed for ship straightening. Each Terac includes a frequency converter, cooling system, operator panel and deck-heating unit..

A handheld unit replaces the deck unit when straightening bulkheads.

Straightening with induction heating

The handheld transformer lets operators heat bulkheads and hard-to-reach areas.

Note the easy-to-use controls placed on the handle.. It usually takes only a couple of hours to train an operator to use a Terac system..

Terac components are designed and built to last in tough shipyard environments.
