Some properties of laser claddings made with several
commercially available alloy 625 powders were
investigated. Nickel based alloy 625, generally
known also as Inconel 625, is widely used also on
laser claddings due to its good corrosion properties in
various environm...$28.00

Presented at ICALEO 2012
An investigation is described that studies the effect of angle of beam incidence using ytterbium fiber laser cladding of alloy 625 (UNS N06625) on matching substrate. The trials include single pass without powder feeding and single pass, 3 pass upslope and 3 pass downslope with powder feeding. Power is held constant in initial single pass trials and then adjusted to maintain constant power d...$28.00
