Laser cladding with various methods have been utilized for some years with increasing quantity. Powder has been traditional type of consumable, but some usage of wires has been reported as well. There are also a number of cladding reports with preheated wire deposition. The aim has been to increase the low productivity of laser cladding. The preheating has been produced by various methods, for instance induction, plasma flame and resistance of the wire. This study compares the different deposition techniques with powder, cold wire and resistance heated wire processes. Hot wire cladding increases the deposition rate substantially keeping similar properties of powder and cold wire laser cladding.
