Understanding the AWS A5.16 Standard
The American Welding Society (AWS) A5.16 specification prescribes the chemical and mechanical requirements for titanium and titanium-alloy wire and rods. Because titanium is highly reactive at elevated temperatures, the purity of the filler metal is paramount.AWS A5.16 ensures that consumables like ERTi-2 and ERTi-5 maintain ultra-low interstitial elements (Oxygen, Nitrogen, Hydrogen, and Carbon). High-purity wire prevents hydrogen embrittlement and weld porosity, the two most common failures in titanium fabrication. TSM Technology Co. utilizes Vacuum Arc Remelting (VAR) to guarantee the metallurgical stability required by this stringent standard.
Key Classifications of Titanium Welding Wire
Choosing the right grade of AWS A5.16 titanium wire depends entirely on the base metal being joined and the intended environment of the finished product.
Commercially Pure (CP) Grades
ERTi-1: The softest and most ductile grade. It is used where maximum formability is required and strength is a secondary concern.
ERTi-2: Often called the "workhorse" of the industrial world. It offers an excellent balance of strength and corrosion resistance, making it the most popular choice for chemical processing and marine applications.
ERTi-3 & ERTi-4: These grades offer progressively higher strength due to increased oxygen content but at the cost of reduced ductility.
Titanium Alloy Grades
ERTi-5 (Ti-6Al-4V): The most widely used titanium alloy globally. It provides high tensile strength and is heat-treatable, making it indispensable for aerospace and defense.
ERTi-7: Enhanced with palladium, this grade offers superior resistance to crevice corrosion in acidic chloride environments.
ERTi-23 (Ti-6Al-4V ELI): The "Extra Low Interstitial" version of Grade 5. It is the gold standard for medical implants due to its superior fracture toughness and biocompatibility.
Mechanical Properties of AWS A5.16 Wire
While the filler metal itself has measurable properties, the performance of the final weldment is the ultimate metric. However, the wire's inherent strength and ductility provide the foundation.
Table 2: Typical Mechanical Properties (Annealed State)
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HV) |
| ERTi-1 | ≥ 240 | ≥ 170 | ≥ 24 | 120 |
| ERTi-2 | ≥345 | ≥ 275 | ≥20 | 160 |
| ERTi-5 | ≥ 895 | ≥825 | ≥ 10 | 330 |
| ERTi-23 | ≥ 860 | ≥ 795 | ≥ 10 | 310 |
