Abstrakt:	The effect of argonarc welding modes on the structure and phase composition of a pipe welded joint made of HP40NbTi alloy is studied by computer simulation and experimental methods. The reduction of heat input due to the use of pulsed welding was shown to be an effective method for inhibiting the phase transformation of niobium carbide and preventing the formation of an undesirable G-phase in the structure of the welded joint. The possibility of purposeful regulation of the structure and, as a consequence, properties of the welded joint by optimizing the parameters of the technological process using numerical simulation in the LS-DYNA software environment is demonstrated.
