Abstract
Conditions providing defect-free welds on low titanium alloys by using narrow-gap magnetically controlled arc TIG welding were experimentally studied. The mechanisms causing deflection of the welding arc at different parameters of the welding process were established.
 
 
Keywords: titanium alloys, TIG welding, tungsten electrode, magnetic control of the arc, deflection of the arc, weld metal
