Gr1 Titanium Welding Wire

Titanium Grade 1 is the softest, unalloyed grade of titanium with the lowest strength and highest ductility. It's weldable, cold formability and an impact-resistant alloy. Titanium Grade 1 has good resistance to mildly reducing conditions and very good resistance to strong oxidizing environment with or without chlorides. The alloy is used for a variety of applications, including for plate heat exchangers, chemical equipment, chlorine production, desalination and anodes.

Titanium welding wire is a high purity titanium alloy material. The main uses of titanium wire include: welding wire, production of springs, rivets and so on. It is widely used in aviation, marine, petrochemical, medicine and other fields.

 

Shielding Gas:

Primary shielding: 100% Argon or Argon/Helium mixtures

Purity requirement: ≥ 99.995%

Trailing shield and backup gas recommended for critical applications

 

Precautions:

Clean surface thoroughly before welding

Remove all oxides, oils, and contaminants

Use dedicated stainless steel brushes for titanium only

Maintain inert gas coverage until temperature drops below 300°C (572°F)

 

Typical Parameters (TIG Welding):

Thickness	Diameter	Current (A)	Voltage (V)	Gas Flow Rate

Q1: What is the difference between Gr1 and Gr2 welding wire?

Gr1 has lower oxygen and iron content than Gr2, resulting in higher ductility and slightly lower strength. Gr1 offers maximum formability and corrosion resistance, while Gr2 provides a balance of strength and ductility. Gr1 is preferred for applications requiring maximum flexibility and corrosion performance.

 

Q2: Is Gr1 welding wire suitable for welding other titanium grades?

Yes, Gr1 wire is suitable for welding Gr1 and Gr2 base metals. For welding higher-strength alloys like Gr5 (Ti-6Al-4V), Gr5 filler wire is typically recommended.

 

Q3: How should titanium welding wire be stored?

Store in a clean, dry environment at room temperature. Keep in original sealed packaging until use. For opened spools, store in a sealed container with desiccant to prevent moisture absorption.

 

Q4: What shielding gas is recommended?

100% argon with minimum 99.995% purity is standard. Argon/helium mixtures can be used for deeper penetration. Trailing and backup shielding is required for critical applications.

 

Q5: Do you provide spool sizes for automated welding?

Yes, we supply precision-wound spools compatible with most automated TIG and MIG welding systems. Please specify your equipment requirements.

 

Q6: What certifications are available?

Each shipment includes a Mill Test Report (MTR) certifying chemical composition and mechanical properties. Additional certifications (EN 10204 3.1/3.2, NORSOK, etc.) are available upon request.
