This paper provides an overview of the commonly used processes and equipment for laser cladding, including pre-set powder feeding, simultaneous wire feeding coaxial cladding nozzles. By comparing above related nozzles, coating characteristics are summarized selection appropriate methods in different working environments. Meanwhile, morphology properties clad layers shaft parts processed with pr...

Abstract In order to know the influence of laser power on steel (27SiMn) used for repairing column with Inconel 718 powder materials, and obtain optimal parameters best mechanical properties cladding layer, microstructure, tensile fracture morphology alloy under three powers (1800 W, 2100 W 2400 W) were investigated by using single-factor variable method, keeping scanning speed, feeding amount ...
