Informationen über plasma powder PTA welding
|
For armouring hard-face flight screws we employ the plasma powder arc welding process (PTA) . The animation demonstrates the production cycle. Special iron-based, hard-facing alloys, high in vanadium, can be welded on flawlessly as flight armour. The many years of expertise guarantees a subsequent perfect machining with the best results and highest wear resistance of the screw flights.Subsequent nitriding additionally protects the screw root and screw flank from wear.
