In collaboration with the best companies in the industry and with selected and certified laboratories, GFM puts on its components all major finishing treatments: COATING; HEAT, PLATING, AND THERMOCHEMICAL TREATMENTS.
Coating with materials such as chromium carbide and stellite can be done by welding, spraying or using HVOF technology. They may also be in white metal, of varying degrees, for bearings.
GFM HEAT AND THERMOCHEMICAL TREATMENTS include: Vacuum Hardening, Quenching, Tempering, Stress Relieving, Normalization, Stabilization, Aging in Vacuum and Nitriding. The main SURFACE TREATMENTS are: Zinc Electroplating, Polishing, Phosphating, Nickel Plating, Chrome Plating and Silver Plating.
GFM staff is constantly brought up to date of cutting edge technology and thus has a considerable knowledge of building standards and welding of several products.
We perform tig, electrode, wire and submerged arc welding processes and our workers are qualified in accordance with ASME IX and EN standards.
The validation of the welding process is managed by:
• Qualification of the welding (PQR / WPAR)
• Issuance of special welding specifications (WPS: Welding Procedure Specifications)
• Qualification of the welding experts (WPQ)
• Appropriate management of welding materials
• Records of checks carried out
