Laser Welding Optimization Procedure Applied to Cobalt Alloys for Removable Partial Dentures
Optimization of fractured or destroyed removable partial dentures realized from CoCrMo alloys are possible due to modern welding equipments. The aim of study was to offer the processing and welding optimal parameters for some long lasting prosthetic pieces. There are investigated two cobalt based alloys, used for dental applications, types CoCrMo. Laser welding equipments was a Mini Laser XXS (Orotig Italia) and the tested samples were welded in butt joint, without filler material. There are presented in comparison results concerning macro and micro structural analysis made on stereomicroscope OLYMPUS and Reichert microscope. Finally a correlation between different welding parameter values and structural features was made.
