A parallel multi-frontal solver is developed for finite element analysis of arc-welding process, which entails phase evolution, heat transfer, and deformations of structures. We verify the code, which is implemented using the hyper-elastoplastic formulation based on Simo and Miehe, via comparison to a commercial code, SYSWELD. Attention is focused on the implementation of the parallel solver using MPI library, on the speedup by parallel computation, and on the effectiveness of the solver in welding applications.
