Induction heating for marine and shipbuilding
Shipbuilding involves some of the largest steel structures in industrial manufacturing, and induction heating is used to straighten, bend, weld and join them. ENRX builds the machines for the work, led by Terac, its system for controlled deck and bulkhead straightening, alongside mobile and stationary systems for pre-heating, post-heating and brazing.
Why shipyards choose ENRX machines
- Faster straightening: localised induction heat can cut deck and bulkhead straightening times by up to 80%
- Precise correction: heat goes only where it is needed, so the material is adjusted without damaging the surrounding areas
- Repeatable results: Terac supports safe, accurate and repeatable straightening, with operator control
- Built for the yard: Terac is designed for demanding industrial environments, with mobile systems available for work in the yard
Straightening
- Deck and bulkhead straightening with the Terac system
- Panel correction and structural alignment
- Straightening of steel sheet
- Straightening of welded T-beams with compensating heating
- Straightening of large steel structures
Plate bending, pre-heating and post-heating
- Pre-heating of steel plate for bending
- Pre-heating of plate before welding
- Post-heating of plate after welding
Paint and coating removal
- Heating of steel plate for paint removal
Brazing
- Brazing of copper tube and brass fittings for piping systems

-
Induction heating is widely used to straighten ship decks and bulkheads.
-
An ENRX Terac system ensures failsafe operation—it makes it impossible to overheat magnetic steel.
-
Terac works just as well on bulkheads and other vertical structures as it does on decks.
-
Operators can work with Terac within a 45m radius of the base unit. An optional extension unit lengthens the work area to 60m radius.
-
ENRX Terac systems are specially designed for ship straightening. Each Terac includes a frequency converter, cooling system, operator panel and deck-heating unit.
-
Terac components are designed and built to last in tough shipyard environments.
-
Note the easy-to-use controls placed on the handle. It usually takes only a couple of hours to train an operator to use the Terac system.
