WAFO-System Technology

The answer from WAFO with screw wear
Since 1997 we have a modern screw service centre, to enable screw regenerations with increase in value through abrasion resistant top surface armouring in the shortest processing time.
For the welding process we use a CNC controlled plasma powder welding plant (PTA) of the newest aggregate generation. The process allows qualitative high quality and reproducible top surface, flanks and full armouring.
The mechanical processing of the renewed screws occurs partially on self- developed machines.
