Titanium welding wire is used for welding titanium reactors, storing acidic or alkaline substances in tanks, and titanium equipment.

Material: TA1, TA2, TA9, TC4. Specifications: φ0.8～φ7.0. Shape: coiled wire, straight wire. Implementation standard GB/T 3623-2007.

PRECAUTIONS

1. Construction workers and welders should wear clean white gauze gloves (cotton gloves are strictly prohibited).

2. It is strictly forbidden to touch or contact iron objects with hands in the treated welding area.

3. Welding work should be carried out indoors as much as possible, and the ambient wind speed should be ≤0.5m/s to avoid being affected by through wind.

4. Short arc welding should be used as much as possible during welding, with small welding heat input, and the nozzle and the weldment should maintain an angle of 70 to 80 degrees.

5. When positioning welding the butt pipe, the butt gap is generally about 0.5mm.

6. Each weld should be welded in one go as far as possible. For welds that must be welded, the interface should be cleaned before welding, and the weld overlap length should be 10-15mm.

7. During welding, the welding torch should not swing left and right, and the melting end of the welding wire should not be moved out of the gas protection zone.

8. Gas should be supplied in advance when welding and arcing. The welding torch should not be lifted immediately when the arc is extinguished. The gas supply should be delayed until the temperature drops below 250℃.

9. The distance between the gas shield and the welding torch should be as short as possible, and the gap in contact with the pipe wall should be minimized. When butt welding pipes, in order to achieve the requirements of single-sided welding and double-sided forming, welding is carried out in two times: one is bottom welding (no filling material is required for bottom welding), and the other is forming welding. When welding multiple layers, the previous weld must be completely cooled before welding the next weld.
