Instructions for Welding Titanium: Titanium is generally welded using the same techniques as stainless steel， however， titanium requires much greater weldjoint cleanliness along with extensive inert gas shielding. •Cleaning: Grind or file away mill scale. Remove surface oxides with SÜA 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

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.
• ERTi-1. Grade 1 is the lowest strength unalloyed (or Commercially Pure) grade. Grade 1 is used in applications where ductility is paramount， such as explosive cladding， loose linings， expanded metal， and deep drawing applications.
• Commonly used in cryogenic and petrochemical applications such as chemical process heat exchangers， pressure vessels and piping systems， electrochemical storage tanks. It is also used in electrolytic applications like coated anode substrates for the production of chlorine and sodium chlorate.
• The weld deposit is ductile and offers excellent corrosion resistance in oxidizing environments. ERTi-1 is the purest grade and is suitable for welding Titanium grade 1， 2， 3， and 4. These rods comply with AWS A 5.16 : ERTi-1， UNS : R50100， EN ISO 24034 : STi-0100 and DIN 1737 : SG Ti 1.
• 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.
