Description and Application
AMPCO-CORE® 200 is an aluminum bronze flux core wire for use with the Gas Metal Arc Welding process.
AMPCO-CORE® 200 is primarily an overlay filler metal. The high strength values of the deposit combined with excellent wear-resisting characteristics make this alloy unsurpassed for bearing overlays where extreme wear and high pressures are encountered in service.
High speed bearings
Welding position and deposits
The flat welding position is recommended. Backhand (trailing) welding is preferred rather than forehand (pushing) to make either stringer or weaved beads.
