Sažetak
Cobalt-chromium alloys are used as standard restorative material in prosthodontics. Some errors in laboratory procedure or breaks of metallic parts during functional period must be repaired. The purpose of this study was to compare joint quality, obtained by different thermal techniques on Co-Cr as cast alloy. Three samples (32x 10 x 1,5 mm) of each alloy were cut and joined by soldering, laser and Tungsten Inert Gas (TIG) welding. All samples were I-shaped. The connested surfaces were analysed by microscope, under 50 - 200 X magnification. From the macroscopic view, soldering of all specimens was successful. On the welded samples, either by laser or by TIG welding, overlapping of welding spots was insufficient, cracks and porosity were present. There is a need for proper handling and optimization of all parameters (impulse duration, voltage and power) for each applied method and for analysed alloys. It could be concluded that macroscopic analysis of the quality of joint, done by technician, is one of the aspects to predict the functional durability of
prosthetic construction.
