METHOD OF WELDING PARTS WITH VIBRATORY WELDER HAVING LOW THERMAL CONDUCTIVITY TOOL AND HIGH MECHANICAL CHARACTERISTICS; CORRESPONDING VIBRATORY WELDER

摘要

In accordance with an aspect of the present disclosure, a vibratory welder for welding parts together has a vibratory tool made from a material having a low thermal conductivity of no greater than 5 watt/meter degree Kelvin and also having a sufficient strength and toughness for vibratory welding. In an aspect, the vibratory tool is made of a material having a compressive strength of at least 80 MPa (megapascals) tensile and a fracture toughness (Klc) of at least 3 MPa(m)1/2.
