21 years of experience in titanium metal manufacturing
Zirconium Wire Welding
XI AN LINHUI IMPORT AND EXPORT Co., LTD. manufactures high-purity Zirconium Wire Welding materials conforming to UNS R60702 and ErZr2 classification under ASME SFA 5.24 standard. With ISO9001 certification, two dedicated factories, and 30 titanium metal production lines, we bring 21 years of manufacturing expertise to reactive metal welding applications.
Our products serve critical corrosion-resistant joining operations where conventional filler metals fail. Each spool undergoes rigorous interstitial gas analysis and dimensional verification to ensure consistent feedability in automated GTAW/TIG and GMAW/MIG systems. Direct mill supply eliminates middlemen costs while maintaining full heat-number traceability.
Key Features & Benefits
Superior corrosion resistance in boiling sulfuric and hydrochloric acid environments. Self-healing oxide film prevents weld decay and intergranular attack.
Strict interstitial control (H<25 ppm) eliminates delayed hydride cracking risk. Oxygen, nitrogen, and carbon levels maintained within tight tolerances for maximum ductility.
Precision diameter tolerance of ±0.05mm ensures smooth wire feeding. Compatible with automated welding systems for high-volume production runs.

FAQ
Q: Can your wire weld Zirconium to stainless steel?
A: No. Divergent welding makes fragile intermetallics. Utilize hazardous holding or mechanical joints instead.
Q: What protecting gas immaculateness is required?
A: Least 99.999% Argon with dew point underneath -50°C. Trailing shields ensure cooling weld underneath 400°C.
Q: How do you avoid weld contamination?
A: Chemical cleaning expels all greases. Administrators wear clean gloves; indeed unique mark oils cause rejection.
Q: What does blue weld discoloration indicate?
A: Deficiently gas protecting amid cooling. Overwhelming oxidation requires weld evacuation and rework.
Q: What's the distinction between R60702 and R60705?
A: R60702 offers most extreme ductility. R60705 gives higher quality for Zr-Nb combination base metals.
