Abstract
This paper presents a modernized installation for impacting a workpiece with electric current pulses whereby ensuring high quality of parts manufactured from titanium alloys. Electrical processes that occur when using a new method of switching an active-inductive load using a three-phase contactless thyristor starter are examined. The use of such a device can eliminate long transient processes during switching, improve control of the heating parameters of the workpiece and provide plasticization of the metal in short periods of time. Other positive effects of the three-phase contactless thyristor starter include the elimination of defects in the structure of the material, increase in the thermodynamic stability of the metals as well as in the structural strength and endurance, reduction of the anisotropy of the metals and the level of residual stress.
