China Customized Titanium Welding Wire Wholesale Suppliers Factory

Titanium Welding Wire for TIG, MIG and Plasma Welding: ERTi Grades, 0.4–6.0 mm, Pickled or Bright Surface

Shaanxi Chuanghui Daye Metal Material Co., Ltd. supplies filler metal for titanium and titanium alloy parts. One product in that line is Titanium Welding Wire. It comes in eight grades: Gr1, Gr2, Gr3, Gr4, Gr5, Gr7, Gr9 and Gr23. The wire is made to ASTM B863 and AWS A5.16. Diameters start at 0.4 mm. They go up to 6.0 mm. Straight wire is one order option. Natural coil is another. D100/D300 coil is a third choice. Pickled finish is available. Bright finish is also available. TIG welding is an everyday use. MIG welding is another. Plasma welding uses it too. Laser welding does as well. Send the grade of your base metal and the joint details. The team will then confirm the right wire for your order.

What Is Titanium Filler Wire?

Weld titanium and titanium alloy parts, and you add a filler metal to the joint. That filler is this product. Both AWS A5.16 and ASTM B863 classify it. GTAW (TIG) and GMAW (MIG) are the common processes for it. Plasma Arc Welding (PAW) also uses it, and so does Laser Beam Welding.

The filler has to match the base metal's strength, ductility and corrosion resistance. Plain steel filler cannot do that job on titanium. Titanium picks up oxygen and nitrogen at high temperature, and hydrogen as well. Low interstitial impurities and a clean surface are therefore what the wire needs.

Grade Guide: Match the Wire to the Base Metal

Pick the filler grade by looking at the base metal first. The standard that applies matters too, and so does what the joint has to do. ERTi-2 is a commercially pure (CP) filler. Its microstructure is single-phase alpha. You run it with ASTM Grade 2 base metal, and with other unalloyed grades as well.

Corrosion-resistant fabrication often uses the commercially pure grades. ERTi-2 gives moderate strength. It also has good ductility. One place it shows up is wet chlorine service. You also see it in seawater lines. Nitric acid lines are another spot.

Aerospace buyers often look at ERTi-5. Crevice corrosion is a worry in some chemical piping. There, ERTi-7 is a common pick. You can also get Gr1, Gr3, Gr4, and Gr9 wire. Send your base metal grade. Our team will help match the wire.

Why Wire Cleanliness Matters

Titanium does not stay inert for long. Heat makes the affected zone (HAZ) pull gases out of the air quickly. That leads to two big issues.

First comes alpha case. Oxygen builds up in this surface layer and makes it brittle. The second is hydrogen embrittlement. Cracks from it may only appear much later. Surface oxide and hydrogen picked up by the wire can also bring on weld porosity.

Clean titanium welding wire with low interstitial content keeps the weld ductile. Its corrosion resistance holds up too. Aerospace and chemical processing parts rely on this. In those sectors, weld quality counts above all.

Applications

Aerospace and aviation: engine parts and turbine components land here. Airframe structures do too. Most of them are built from ERTi-5.
Chemical and petrochemical processing: heat exchangers and condensers are common. So are reactor vessels, and piping that meets wet chlorine or acids. For the piping side, ERTi-7 often comes up.
Automotive and marine: exhaust parts belong in this group. So do boat fittings mounted where chloride levels run high.

Surface Finish and Supply Forms for Titanium Welding Wire

You can order either pickled wire or bright surface wire. Think about how you clean and how you weld, then choose the finish that suits it.

Our sizes run from 0.4 mm to 6.0 mm. Straight wire is available. Natural coil is the other choice. D100 and D300 are the two coil options. Each order sets its own length. Tell us your packaging needs when you send the inquiry.

FAQ

Q: What is titanium filler wire?

A: This is the filler metal that joins titanium and titanium alloy parts. AWS A5.16 and ASTM B863 are the standards it follows.

Q: What is Gr2 wire, also called ERTi-2?

A: This filler is made of commercially pure titanium. It suits Grade 2 base metal. Strength stays moderate, and ductility holds up well.

Q: Which welding processes can be used with this product?

A: GTAW (TIG) and GMAW (MIG) are used. So are Plasma Arc Welding and Laser Beam Welding.

Q: Which grade suits my industry?

A: Aerospace buyers often consider ERTi-5. Chemical processing buyers often consider ERTi-7. General corrosion-resistant fabrication often uses ERTi-2. The final choice depends on your base metal and specification.

Q: What sizes and forms can you supply?

A: Diameters are 0.4–6.0 mm. Forms are straight wire, natural coil and coil in D100 or D300. Length is set per order.

Q: Which surface finish should I choose?

A: Both pickled and bright surfaces are available. Email your process details to info@chdymetal.com and the team will advise.
