Friction Welding Systems

Friction stud welding is a solid phase (no melting of materials) process where the stud is rotated at high speed and forced against the parent material producing heat from friction and forge, welding the stud to the metal surface.

This method produces higher quality stud welds with excellent fatigue life, far better than can be achieved by arc welding.  Proserv Offshore's portable Friction Stud Welding systems are used for special applications such as welding underwater and welding safely topside in explosive environments. 

Studs from 3mm to 25mm diameter can be welded in a very wide range of materials including stainless steels, high strength steel, titanium, aluminium and armour plate.   

Our Friction Stud Welding system includes a welding head, a reaction clamp and either compressed air or hydraulic power. 

Systems available weld from 3/16" to 1 ½" diameter studs and tubular up to 2 ½" diameters.  

Friction Welding underwater

When welding underwater, the stud is encapsulated in a protective shroud that prevents quenching by the surrounding water.
