Abstract
The efficiency of application of narrow-gap nonconsumable-electrode argon-arc welding of titanium alloys of > 20 mm thickness is noted. It is shown that in order to provide a reliable fusion in the joints when using a transverse variable magnetic field, the value of magnetic inductance in the arc zone should be equal to 8–9 mT. Minimum penetration of the side walls is achieved at the field frequency of 10 Hz.
Keywords: argon-arc welding, narrow gap preparation, titanium alloy, tungsten electrode, penetration, side wall, magnetic induction, field frequency
