FORMATION OF NARROW-GAP WELDED JOINTS ON TITANIUM USING THE CONTROLLING MAGNETIC FIELD

Abstract
The mechanism of formation of welded joints in a narrow groove under the external effect of the controlling magnetic field is suggested. Dependence of the argon plasma flow rate and gas-dynamic pressure of the arc on the weld pool surface upon the welding process parameters and tungsten electrode geometry was established by the experimental-calculation method.
