Abstract

In this study was conducted welding) the type of “limited connectivity “(under atmospheric pressure using pulsed Nd:Glass laser to weld (silver, copper, tin) used in dentistry, ensure that research study the specifications of welding and which of them were measuring the breadth of the affected area, the depth of welding, diameter Interaction with energy. In addition to bullion subjected to several tests, including X-ray diffraction (XRD) and mechanical tests tensile and hardness and comparing the results obtained with results available in the reference standard (ASTM) to determine the characteristics of these stages bullion and through research was stressed that the process(γ-Ag3Sn), A percentage basis in the output methods and the presence of elements involved in bullion ((B and the disappearance of tin in bullion (A). results negatively on the mechanical specifications, as shown tensile strength and hardness tests conducted it.
