Objective To compare the ultimate tensile strength of the soldering joint from conventional torch technique and the welding joint from laser technology in three types of alloy, gold-palladium (Au-Pd) alloy, nickel-chrome (Ni-Cr) alloy and cobalt-chrome (Co-Cr) alloy using the ISO standard model. Materials and methods Fifty four specimens were prepared in accordance with ISO 6892 from three different alloys, Au-Pd alloy, Ni-Cr alloy and Co-Cr alloy. Six specimens of each alloy were cut and either soldered with gas propane-oxygen torch or welded with laser. The control group was six specimens without cutting (as cast specimens) of each alloy. All specimens …
