Submerged Arc Welding of Titanium.

Abstract

Studies of flux shielded welding of titanium indicate that acceptable submerged arc weld bead shape may not be attained with pure CaF2 flux. Addition of chlorides to the CaF2 flux improves the weld bead shape but reduces the deoxidizing potential of the flux. Use of cored electrodes containing chloride salts produces the most acceptable weld beam profiles. Preliminary studies of titanium weld penetration in the presence of several fluoride salts indicate that changes in flux chemistry may be useful in modifying the weld bead profile. Economic analysis indicates that SAW of titanium can only be competitive with gas metal arc welding if the flux cost can be reduced significantly. A possible method of reducing flux cost may be recycling of the fused slag. (Author)
