1. Titanium welding filler rod is a metal filler welding wire for Tig welding, it has excellent welding process performance, and beautiful weld formation and its weld metal has excellent comprehensive mechanical properties. It is mainly used for the welding of titanium and titanium alloys.
2. Available criteria and grades
ERTi-1, ERTi-2, ERTi-4, ERTi-5, ERTi-7, and ERTi12 are the grades.
Size: 1.6, 2.0, 2.5, 3.2, 4.0, 5.0, 6.0, 8.0.
Surface treatment: pickling surface, bright surface
State: Annealed state (M) Hot working state (R) Cold working state (Y) (annealed, ultrasonic flaw detection)
Standards: AWS.A5.16
3. What is the characteristic of a titanium welding filler rod?
Surface quality: extremely accurate, well-finished, free of oxidation, and without flaws like peeling, inclusions, thorns, or stains. It's acceptable to have minor localized abrasions, stains, pits, and other imperfections as long as they don't go beyond the wire diameter's authorized deviation.
Surface finish: clean, dust-free, better acid-resistant service life.
Physical characteristics: excellent strength and elongation characteristics; no deformation after cold bending. Wires with a diameter of more than 3mm should be free of shrinkage, pores, delamination, cracks, and metallic or non-metallic inclusions.
