Titanium MIG Weld Wires, TIG welding rods to the titanium welding process are available with us. Titanium welding wire and rod is covered by AWS A5.16-70 Specification (“Titanium and Titanium-Alloy Bare Welding Rods and Electrodes”). It is generally good practice to select a filler metal matching the properties and composition of the titanium base metal grade. However, for both commercially pure grades and alloys, selecting a weld wire one strength level below the base metal is also practiced.
