Summary: High power direct diode lasers [HPDDL] are highly suited for cladding surface areas traditionally clad by means of typical arc welding processes. This paper investigates the advantages and disadvantages of using the HPDDL for cladding when compared to the Gas Tungsten Arc Welding [GTAW], Gas Metal Arc Welding [GMAW], and Submerged Arc Welding [SAW] cladding processes. Deposition rate, heat input, base material dilution, bead profile, operating conditions and cost comparisons are all discussed.
