Plasma transferred arc process

The plasma transferred arc process has been developed to apply a metallic bond high-alloy surface coating. The cladded surface allows the life span of worn and new parts to be extended and replacement costs to be decreased. Cladding new parts has also the advantage of increasing the output of machinery or lowering its maintenance costs. Plasma cladding increases the long-term productivity of parts which are exposed to extreme temperatures, corrosion and strong erosion by applying layers of Cobalt, Nickel and Chrome alloys (Stellite, Inconel).

Features 

• Hardness varies depending upon the selected alloy, up to 700 HV 30.
• The process is fully automatic. This results in high quality and homogeneous deposits without porosity or inclusions.
• Low rate of dilution, the lowest possible with arc welding.
• Layer thickness from 2 to 5 mm.
• Internal welding up to minimum of 50 mm diameter.
• External welding process up to a maximum of 2000 mm.
• PLC controlled arc correction.
• Registration of all welding parameters.

Applications 

• Valve and seats for control equipment with high flow speed gasses and liquids.
• Mechanical seats.
• Cold/hot forming and cutting tools.
• Parts for use in highly corrosive environment.
• Glass forming tools.
