Paper Abstract

A novel laser processing system for industrial surface engineering has been developed. It consists of wide-band laser scanner and wide-band powder feeder. It is used to laser cladding, alloying and surface hardening on the larger area, as well as welding. The system can provide single pass quenching or cladding widths with adjustable from 10 - 35 mm. The system was designed for delivering powder at precisely measured tolerance limits less than 2% and adjustable fed rate 0.5 - 200 g/min to produce the continuous, uniform and controlled laser cladding of 0.2 - 10 mm thickness, emphasis has been placed on repeatability, reliability as well as high powder utilization factor over 90%. All kinds of powders including not only Ni, Fe, Co and Cu base, but also ceramics powders ZrO2, Al2O3, WC and TiC can be fed. Without the carrier gas the powder flow depends mainly on gravity. It is successfully used to some surface engineering for metallurgical, automobile, oil and mechanical industries.
