View DetailsTitanium Tig Wire
A dedicated filler wire for Gas Tungsten Arc Welding (GTAW/TIG) of titanium alloys, designed to ensure weld integrity and corrosion resistance.
Product Overview
Bokang's Titanium Tig Wire is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
Titanium TIG wire is a non-consumable electrode welding process used specifically for joining titanium and its alloys. The wire serves as the filler material, melted by the heat of the tungsten arc to form the weld joint.
This wire is manufactured to match the composition of base titanium metals such as Grade 1, 2, 5 (Ti-6Al-4V), and others, ensuring the resulting weld possesses mechanical and corrosion-resistant properties equivalent to the parent material. Successful welding with titanium TIG wire requires strict atmospheric shielding, typically with argon gas, both from the torch and often via a trailing shield or purge chamber, to prevent contamination by oxygen, nitrogen, or hydrogen at elevated temperatures. It is commonly supplied in straight lengths, with surface cleanliness and precise diameter tolerances being critical for consistent feedability and weld pool stability.

Key Advantages of Bokang Titanium Tig Wire
Discover why our titanium wire stands out in the industry
Precise Composition Control
Chemistry is tightly controlled to match base metal specifications, ensuring weld metal properties like strength and ductility meet required standards.
Optimized Surface Finish
A clean, smooth, and grease-free surface minimizes the introduction of impurities into the weld pool, which is critical for reactive metals like titanium.
Consistent Feedability
Accurate diameter and straightness allow for smooth manual feeding during the TIG process, contributing to uniform bead appearance and penetration.

Material Selection Guide
How to choose the right titanium wire for your application
1
Match Base Metal Grade
Select a filler wire grade that matches or is compatible with the base titanium alloy. For pure titanium (Grade 1,2), use ERTi-1/2. For Ti-6Al-4V (Grade 5), use ERTi-5.
2
Consider Joint Design and Diameter
Choose wire diameter based on material thickness and joint geometry. Thinner materials (below 1.5mm) typically use 0.8-1.0mm wire, while thicker sections may require 1.6-2.4mm wire.
3
Assess Service Environment
For applications requiring enhanced corrosion resistance or high-temperature stability (e.g., chemical processing), consider grades like ERTi-7 (Pd stabilized) or ERTi-12.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Raw Material Preparation
High-purity titanium sponge and alloying elements are pressed into electrodes under inert atmosphere to prevent contamination.
→
Vacuum Arc Melting
The electrode is melted in a Vacuum Arc Remelting (VAR) furnace, often multiple times, to achieve a homogenous and impurity-free ingot.
→
Hot & Cold Forming
The ingot is forged, rolled, and drawn through a series of dies at controlled temperatures to reduce it to the target wire diameter.
Surface Finishing & Cleaning
The wire undergoes pickling, grinding, or polishing to remove surface scale and oxides, followed by ultrasonic cleaning.
Straightening, Cutting & Packaging
The wire is straightened, cut to precise lengths, inspected, and immediately vacuum-sealed in protective packaging to maintain cleanliness.
Frequently Asked Questions
Common questions about pure titanium wire
Titanium is highly reactive and begins to form an oxide and nitride layer upon exposure to air at room temperature, and rapidly at welding temperatures. This layer can compromise weld integrity. Vacuum packaging prevents this atmospheric contamination during storage and transport, ensuring the wire surface remains clean for welding.
While pure argon is common for both, titanium welding demands more rigorous gas shielding. In addition to the standard torch cup, a larger gas lens and a trailing shield are often recommended to protect the hot, solidifying weld bead and heat-affected zone from air. Back purging of the weld root is also essential for full-penetration welds.
