Optimisation of welding conditions for heat exchanger tube plates by computer simulation methods

摘要

A mathematical model was developed for the non-stationary two-phase problem of heat conductivity in pulsed arc welding of tubes to tube plates. Experimental verification of the model confirmed the adequacy of the latter. The model of the process of welding of tube to tube plates may be used for the determination of the parameters of the process of pulsed welding resulting in the maximum depth of penetration and the size of the internal bead not exceeding the required value.
