Abstract

To improve the quality of a joint composed of metallic micro-structural parts, a novel resistance brazing method called the "two-step resistance brazing method" has been developed. In this method, filler metals plated on the surface of base metals are butted and alloyed due to the Joule's heat by performing two-step energizing. In this study, the numerical simulation of the joining process for the two-step resistance brazing method has been performed.
A mathematical formulation and corresponding calculation scheme, which is derived from using the control-volume method, are developed for a model based on contact resistance between the filler metals plated on the surface of the base metals, and transient two-dimensional heat conduction with the Joule's heat generation.
The calculated result, based on a base metal of type 304 stainless steel and plated filler metals of gold and copper, is discussed and compared with experimental data.
