Abstract
The model describing the behavior of resistance brazing process developed here is a one-dimensional, explicit, finite difference model. The finite difference method uses a central difference scheme for the spatial approximation and a forward difference scheme for the transient iteration. The complex geometry of the contact is reduced to simple element via conformal mapping. The model incorporates joule heating, interfacial resistance, forced convective cooling of the electrodes. Radiation and ambient convection are neglected. The model simulates resistance brazing of powder metallurgy contacts to copper terminal quite well. The anticipated transient response is reproduced. The model, in conjunction with an experimental reference, could be used to troubleshoot or develop similar processes. As a result, it is concluded that the method is successful.
