| Research Abstract |
Change of properties and deformation of theree dental metals after laser welding were examined. As a result, the metals were hardened and the metallograph was changed in the fusion zone. Besides, the deformation of the metal farames was smaller when the joint part prepared to bevelled edge compared with square edge and that was smaller when the laser was irradiated with the main pulse and the sabsequent weak addition pulse compared with the only main pulse. In three kinds of the metals, pure titanium was shown the smallest deformation, then Au-Ag-Pd alloy, Co-Cr alloy in that order.
