Pre-Ground Sharpened TIG Tungsten Needle Electrode
1. Application: tungsten needle electrode suitable for inert gas arc welding and plasma welding, cutting, spraying, melting electrode.
2. Features: high melting point, arc stability, no self - consumption.Add 0.03 ~ 4% Th02, Zr02, La02 and Ce02 in tungsten to reduce the burning loss of tungsten electrode, increase its service life and avoid polluting welding seam: increase the electron emission ability of tungsten electrode, make it arc starting current, stable arc current is small, arc starting gap and arc breaking gap are big, so the quality of welding seam is high.
3. The exported tungsten needle electrode is in accordance with the international standard is06848-2004, ANSI/AWS, awsa5.12-98 and other standards.
4. Specification range and dimensional deviation of top quality tungsten needle electrode.
Dia:Φ0.5~15mm Or other specifications customized by the customer.
Dia:≤Φ2.0.mm Tolerance zone:士0.05mm
Dia:≥Φ2.4mm Tolerance zone:士0.1mm
Length deviation:士 1mm
5. Flatness: no more than 0.5% of electrode length.
6. Surface quality: smooth, clean, without defects (cracks, cracks, peeling), no oil and other impurities.
7. top quality Tungsten needle electrode two end faces should be neat, smooth, no burr, no internal defects (loose, impurities) section.
