Titanium Grade 5 MIG Wire (AWS ERTi-5) Manufacturer, Supplier, and Stockist

titanium grade 5 MIG wire
A welder joining high-strength titanium components needs filler wire that can actually match the strength of the base metal once the joint cools, and that is the entire reason Grade 5 MIG wire exists as its own classification rather than buyers reaching for a general purpose filler. Titanium Grade 5 MIG wire is known under the AWS A5.16 specification ERTi-5, and it is specifically used for the gas metal arc welding of Ti 6Al 4V and spooled in a standard MIG feed system size. It also carries the UNS designation R56400, the same designation used for Grade 5 base metal, with controlled aluminium and vanadium content per AWS A5.16 so the welded joint reaches tensile and yield strength close to the base metal. Sachin Steel Centre sells Titanium Grade 5 MIG wire from its location in Mumbai with all spools being duly checked for compliance with all requirements before delivery.

Applications of Titanium Grade 5 MIG Wire

  • Aerospace Structural Welding. Titanium Grade 5 MIG wire produces welds that hold close to the full strength of the surrounding Ti 6Al 4V structure, which is essential for airframe and structural components.
  • Gas Turbine Components. Engine casings, rings and other turbine components welded with Titanium Grade 5 MIG wire retain high strength performance at elevated service temperature.
  • Chemical Processing Equipment. High strength reactors and process equipment welded with Titanium Grade 5 MIG wire keep both the corrosion resistance and structural strength of the base metal through the joint.
  • High-Strength Structural Fabrication. Titanium Grade 5 MIG wire is used wherever a welded joint needs to match Grade 5 base metal strength rather than settle for a softer weld.

Frequently Asked Questions About Titanium Grade 5 MIG Wire

Titanium Grade 5 MIG wire is the AWS A5.16 ERTi-5 filler metal classification, chemically matched to base metal Grade 5 with controlled aluminium and vanadium content so the weld deposit reaches close to the same strength. Both share the same UNS number, R56400, and the same Ti 6Al 4V base chemistry.
100% argon with a purity of 99.995% or higher is standard, with an argon helium blend sometimes used on thicker sections for deeper penetration. A trailing shield and back purge are required until the weld cools below 427 degrees Celsius. n thin sections until the weld cools below 427 degrees Celsius.
Titanium Grade 5 MIG wire carries the UNS number R56400, the same designation used for Titanium Grade 5 base metal and bar stock.
ERTi-2 is a commercially pure titanium filler chosen for ductility and easy weldability, with moderate strength. ERTi-5 is alloyed with aluminium and vanadium to match Grade 5 base metal, giving close to double the strength of ERTi-2 but requiring more careful welding technique.
Yes. ERTi-5 is the AWS A5.16 classification for Titanium Grade 5 filler wire, and Titanium Grade 5 MIG wire refers to that same filler metal wound specifically for the GMAW process.
