Abstract
Mathematical modelling of the metal-arc spot welding process was carried out by the thermoplasticity method combined with the finite element method to estimate the possibility of improving the welding technology. Performance of a spot welded joint under static and alternating loads was evaluated based on the data on size of the fusion zone and level of residual stresses within the weld spot zone.
