ERTI2-1/16 - ERTi-2 Grade 2 Titanium TIG Welding Rod 1/16"

Technical Overview of ERTi-2 Titanium TIG Rods

The ERTi-2 Titanium TIG Rod is a premium-quality filler metal designed for the Gas Tungsten Arc Welding (GTAW) of commercial pure (CP) titanium alloys. Classified under AWS A5.16, this Grade 2 titanium rod is widely recognized as the "workhorse" of the industrial titanium market. It provides an optimal balance of moderate strength and excellent ductility, making it the most commonly specified grade for general corrosion-resistant applications. The 1/16-inch (1.6mm) diameter allows for precise heat control and bead placement, essential when welding reactive metals like titanium.

Metallurgically, ERTi-2 is unalloyed titanium with controlled levels of oxygen and iron to ensure consistent mechanical properties. It exhibits outstanding resistance to corrosion in highly oxidizing environments, including wet chlorine, nitric acid, and metallic chlorides. This makes it indispensable in chemical processing and marine environments. When welding with ERTi-2, strict attention must be paid to gas shielding; the weld pool and the cooling heat-affected zone (HAZ) must be protected by high-purity argon or helium to prevent embrittlement caused by atmospheric contamination (oxygen, nitrogen, hydrogen).

This 5lb tube of cut-length rods (36") is manufactured to rigorous standards to ensure a clean surface finish, free from oils or oxides that could introduce porosity. It is compatible with welding ASTM Grade 2 base metals and can also be used to weld Grades 1, 2, 3, and 4, provided the design requirements match the filler properties. It is not recommended for welding high-strength titanium alloys like Grade 5 (Ti-6Al-4V) unless ductility is the primary concern over strength.
