Titanium Welding Wire

In gas shielded tungsten arc welding (TIG/GTAW), gas melted electrode welding (MIG/GMAW) and tip plasma arc welding (PAW), titanium welding wire is not only a filling metal, but also a key to determine the physical properties of the entire weld and the integrity of micro-structure and grain boundaries. Because titanium easily absorbs interstitial elements such as hydrogen, oxygen, and nitrogen during drawing and welding at high temperatures, trace surface contamination will lead to weld Embrittlement and macroscopic hot cracks.

We launched high-end Engineered Titanium Welding Wires & Filler Metals, which strictly bench-marked and exceeded the international standard of AWS A5.16. The product uses titanium ingots remelted by high-purity electron beam or vacuum consumable furnace as the source, through advanced non-destructive surface peeling process (Peeled Process) and ultra-high vacuum annealing. While ensuring excellent wire feeding smoothness, it realizes ultra-low gas residue and zero microscopic pores, providing the ultimate material support for global high-barrier and high-load welding projects.

I. Excellent core advantages (Elite Engineering Advantages) U

ltra-Clean Peeled Finish-Zero Contamination: A trace amount of drawing lubricant or oxide film is often left on the surface of the drawn titanium wire, which is a fatal cause of welding pores and hydrogen embrittlement. We adopt special on-line mechanical Peeling (Peeling) or fine chemical pickling technology to completely peel off the porous layer and micro-cracks on the surface of the wire to ensure that the cleanliness of the welding wire surface meets photovoltaic and aerospace-grade compliance standards.

Precision Layer Wounding and Isotropic Winding The welding wires are arranged extremely evenly in the Spool state, and the wire diameter tolerance is strictly controlled within ± 0. 02 mm. Whether it is in high-speed automated robot (Robotic Welding) or manual TIG welding, it can guarantee perfect arc length stability and smooth and unimpeded wire feeding experience.

Interstitial Element Mastery (ELI) control technology: Through the absolute high vacuum blockade in the melting and drawing links, the content of deep-level embrittlement elements such as hydrogen (H), oxygen (O), and nitrogen (N) Compressed to an extremely narrow window far below the industry standard, ensuring the balance between impact toughness and plasticity after solidification of the welding pool.

V. Advanced Production Technology and Surface Treatment

Cold drawing of high-purity ingots: high-quality low-impurity titanium wire rods melted by EB (electron beam) for multiple times are selected, and Cold Drawing is carried out through precision super-hard multi-pass cemented carbide or natural diamond molds to precisely control the reduction rate.

Multi-pass ultra-high vacuum intermediate annealing: In order to eliminate drawing hardening, the wires are regularly sent into a 10-4Pa vacuum annealing furnace to complete softening and recrystallization, and the surface has absolutely no high-temperature oxidation color (bright silver).

High-end surface modification (chemical/mechanical peeling): use mixed acid leaching method or advanced scraper peeling process to remove the outermost layer of several microns of draw-hardened layer and oxygen-rich layer of the wire.

Surface treatment and cleanliness testing: Before leaving the factory, it is online ultrasonic degreasing and drying with high-purity alcohol to ensure the implementation of electronic-grade clean delivery of "white cloth without black marks".

VI. Global Cutting-edge Applications (High-Value Market Applications)

Aerospace Structural Welding: Widely used in aircraft fuselage titanium alloy frames, engine compressor blades, casings, and tank fuel tanks (taking advantage of ERTi-5ELI's excellent ultra-low temperature toughness).

Large pressure vessels and special chemical equipment (ASME Chemical Vessels): In the welding of PTA (purified terephthalic acid) plant, acetic acid synthesis tower, and heat exchanger tube sheet, pure titanium ERTi-2 welding wire is the lifeline to ensure the system to resist high-pressure corrosion.

Desalination and Marine Piping: Titanium has natural absolute immunity to seawater and chloride ions, and pure titanium welding wires are used for system docking of offshore drilling platform pipelines and ship pressure hulls.
