ERTI-1

AWS A5.16 ERTi-1

ERTi-1 is a TIG and MIG filler metal used for welding commercial pure

titanium alloys commonly found in applications requiring high temperature resistance and resistance to chemical reagents. Although there are four grades of

Commercial Pure Titanium filler metals, C.P. Grade 2 (ERTi-2) is the most popular because of its good balance of strength, formability and weldability. The most common application of

Commercial Pure Titanium is the aircraft industry, where tensile strength

and weight ratios are so critical. Other uses would include cryogenic and petrochemical applications such as chemical process heat exchangers, pressure

vessels and piping systems, pulp bleaching systems, electro

chemical and chemical storage tanks.
