Recently, the laser welding has gradually been applied as a joining method for dental alloys. Therefore, this study was conducted to develop a welding method for preventing laser welding deformation. In this study, the influence of the fixed strength on the prevention of welding deformation was examined by fixing Ag-Pd-Cu-Au alloy specimen with a soldering investment or silicone rubber. Moreover, the effectiveness of post-heat treatment after welding on the welding deformation prevention was examined. In addition, the deformation result of the laser welding was compared with that of soldering.<BR>The conclusions were as follows:<BR>1. It was effective to compensate for transverse shrinkage to expand joint gap considering the degree of the shrinkage by setting expansion of soldering investment on fixing specimens there with.<BR>2. The strong fixation of specimens with soldering investment could reduce welding deformation.<BR>3. Post-heat treatment of the specimen fixed by investment was effective in preventing the deformation.
