ERTI Titanium Welding Wire

Titanium welding wire is the "metal suture" of high-end manufacturing industry. ERTI Titanium Welding Wire is an industrial pure titanium welding material that meets ASTM/ASME standards and is divided into Gr1-Gr4 grades according to purity (such as ERTi-1 corresponds to Gr1).Its core advantages are super corrosion resistance (resistance to seawater/strong acid and alkali), extremely light density (4.5g/cm³, 43% lighter than steel) and medical-grade biosafety (Gr1 grade passed ISO 5832-2 certification).
Mainly used in: chemical reactor sealing welds, deep-sea pipeline repair, artificial joint implant device welding, nuclear power plant cooling system maintenance. Chenxin provides ±0.02mm titanium welding wire (Minφ0.8mm) and vacuum annealing process to ensure zero defects in welds.

 

 

 

 

Product Advantages

1. Low Impurity Content and Uniform Chemical Composition

The ingots are refined using Vacuum Arc Remelting (VAR) technology with multiple remelting cycles to ensure uniform chemical composition throughout.

Employs bright cold drawing with roller dies and inert gas-protected in-line annealing, eliminating issues such as hydrogen absorption and oxidation commonly associated with traditional hot drawing processes.

2. High Surface Cleanliness and Superior Surface Quality

Radial rolling creates a dense grain structure, reducing surface defects like pitting. The roller-die cold drawing process improves wear resistance and feeding stability, minimizing wire jamming and equipment wear during welding.

3. Argon-Filled Annealing and Straightening for Optimal Wire Form

Chenxin Titanium's annealing and straightening process (thermal tension annealing) enhances wire straightness to within 2 mm per meter, while maintaining a smooth surface free from deformation.

Resulting Welding Advantages
These features provide the following benefits during welding:

Reduced wire feeding resistance, preventing increased friction between the wire and feeding wheel due to excessive bending.

Eliminating wire vibration during feeding helps maintain stable arc length, preventing issues like long arcs that reduce shielding gas coverage-causing weld porosity or oxidation-and short arcs that lead to poor penetration, narrow welds, and spatter from short-circuiting.

Preventing wire bending helps avoid weld path deviation, which can disturb molten pool flow and result in inconsistent weld width, undercutting, or humped weld beads.

FAQ:

Q: How is the purity grade of titanium wire divided?

Chenxin Titanium: According to ASTM standards, it is divided into Gr1-Gr4 (industrial pure titanium), TC4 and other titanium alloys; Gr1 has an oxygen content of ≤0.18%, the lowest strength and the best ductility; Gr4 has the highest strength (≥550MPa).

Q: What is the surface finish that can be achieved?

Chenxin Titanium:Standard products Ra≤1.6μm, polished custom products can reach Ra0.8μm (medical grade requirements).

Q: What is the difference between cold-drawn wire and heat-treated wire?

Chenxin Titanium: Cold-drawn wire: high strength (tensile strength ↑15%), suitable for precision welding; heat-treated wire: good plasticity, suitable for bending and forming parts.
