Four piston crowns can be cycled at the same time on four different operating units. Repair welding approved by ISO 9002. Dimensions are taken and recorded and Dye check inspection is carried to diagnose condition of parts.

Piston heads grit blasted and machined to remove defective areas. All the parts are preheated to a temperature of 200°-300°C. Welding of groover, diameter and top is carried out by the submerged arc.

Welded parts follow the annealing process in automatically controlled furnace

Reconditioning of Valves

Various sizes and seats of valves and types, from B&W MC - SULZER RTA - MITSUBISHI - HANS1N etc are reconditioned to original dimension with Inox and Stelite and Nimonic. We are fully automatic, semi-automatic plus TIG, MIG-MAG PTA. Also aluminium for pistons.

Plasma PTA

The PTA Technology guarantees high efficiency, quality and speed in welding. Excellent surface at low coating volume, high thermal energy of plasma arc using powders as filler material.

Special Welding

This Technology is the best welding solution for valves seats etc.
For Stelite, Nimonic Inconel and Hasteloy. Plasma technology solves a number of welding problems
