Paper Title:
Experimental Assessment by Finite Elements Method of the Residual Stress State and of the Heat Flow from the Laser Weldings of the Alloys of CoCrMo Used in RPD (Removable Partial Dentures) Technology
  Abstract

The welded joints are used in the technology of the removable partial dentures for the rehabilitation of their metal component. The welding procedure and the adequate equipment are established according to the components dimension, the quality of the alloys used and the dentures section. The modifications within the welded structures can be investigated by means of non-destructive tests such as the radiography or the analysis with finite elements. The work was based on the experimental checking of the optimal procedures of welded joint of the alloys of CoCrMo in order to increase their durability. The welded joints were performed in a butt joint configuration with addition of material on the alloys of CoCrMo used in the technology of the framed dentures. The finite elements method was used (software Solid works 2007) in order to simulate the welding process (thermal analysis) and to assess the residual stress areas appeared after the various welding procedures.
