- ***READ THIS: Check Picture #2 for an approximate number of rods per pound. The main image is for reference only. These rods are shipped in a reusable plastic container with a cap that can be used to safely store and transport your rods. Read the description of this product below for a general guide on how to weld titanium.
- This ERTi-5 (Grade 5) Titanium Rod is commonly referred to as “6Al/4V” or simply “6-4” and its primary use is for TIG welding and has a composition alloy of 6% aluminum + 4% vanadium + Balance Titanium.
- Applications: Aerospace, marine, chemical plants, process plants, power generation, oil and gas extraction, medical and sports, aircraft industry components such as landing gear, wing spars, compressor blades as well as turbine engine parts. Other applications include cryogenic and petrochemical industries where higher strength welds in corrosive environments are required.
- ERTi-5 exhibits an ultimate tensile strength of 130,000 psi min, good weldability and can be heat treated to higher strength or toughness. Its corrosion resistance is generally comparable to Grade 2 and it is often used in corrosion service where higher strength is required, particularly in shafts, high strength bolting, and keys.
- Available Diameters: 0.035", 0.045", 1/16", 3/32" and 1/8" - Available Pack Quantities: 10 Rods, 1 Lb and 2 Lb - Select your option from the Size Menu.
Instructions for Welding Titanium: Titanium is generally welded using the same techniques like stainless steel, however, titanium requires much greater weld joint cleanliness along with extensive inert gas shielding. •Cleaning: Grind or file away mill scale. Remove surface oxides with Pickling Paste or 35% nitric – 5% hydrofluoric acid solution at room temperature. Remove any grease or oil with a nonchlorinated degreasing solvent, methanol acetone, or methyl-ethyl-ketone. Light oil can be removed by washing with a household abrasive or detergent. •Fitup: Clamp joints where possible. Tack welds require the same care as other welds. •Equipment: Use a constant-current power source (DCEN) for GTAW with a contactor for arc start and stop. High-frequency starter for manual welding, water-cooled GTA torch with gas lens and ¾-inch (#12) gas cup, 2% Thoriated, 2% Ceriated, 2% Lanthanum or Rare Earth tungsten Note: A reactive metal, titanium is sensitive to embrittlement by oxygen, nitrogen, and hydrogen. Consequently, the molten weld metal must be protected against atmospheric contamination by holding the shielding gas over the weld zone until it cools down to 600°F
