Piston Head and Piston Ring Groove Reconditioning
Piston Crown Reconditioning Procedure
Detailed inspection carried out, aplied crack test and taken / reported all measurement, that will advise us the piston crown is within reconditioning limits and what we must to do
Reconditioning Piston Crown Topland:
Cracks and burned area stripped out. Cracks and cavities repaired / filled up by mig welding( with basic material ) under suitable process and controled conditions. The piston crown machined to prepare for last layer of Nikel base welding. After last layer mig welding and stress relieving under controlled conditions. Last crack test applied and piston crown machined to the original measurement.
Reconditioning Piston Crown Ring Grooves:
Cracks and burned material stripped out. Cracks and cavities welded / filled up with basic stainless stell
material under suitable process and controlled conditions. And piston crown machined to prepare for last layer ( ¾ -1 mm ) of hard face co balt base Satellite welding under suitable proces,controlled conditions. After stress relieving, applied last crack test and piston crown machined to the original measurement and taken / reported last measurement. And we quarantied 10000 working hours.
