Shipbuilding capability

Shipbuilding capability

PROTEM equipment are used for the shipbuilding industry for the manufacturing and ship repair.

They cover a tube diameter range from 3 mm (0,07”) to 2235 mm (88”) as standard. Possibility to go up to 4267 mm (168”) on demand.

They provide great gains in productivity and ensure perfect quality of welded assemblies.

Submarines : Beveling machine for submarine Hulls

Protem designed and manufactured a milling machine with an adjustable machining head which will work on the upper and lower end of the hull section.

The work to be performed is compound bevels on the inner and outer edge of a circular pressure hull section.

Thickness of section varies between 55 and 100 mm

Submarines : Automated Machine for welding submarine hulls

Protem designed and manufactured 3 automated machines using a MIG/NARROW GAP welding heads (10 mm gap. 100mm deep).

The weld is performed in two simultaneous passes though diametrically opposed welding heads in multiple passes using an oscillating wire feeder.

Weld fusion problems are eliminated.

High quality welds are achieved in both vertical and horizontal position.


The work to be performed is to weld thick plates ( 120 mm) using MIG/NARROW GAP process (horizontal and vertical).
