Description of argon arc welding wire

Argon arc welding wire is a kind of inert gas shielded welding, which has the following characteristics:
1. Argon has good protection effect and can obtain high-quality welds.
2. Stable arc combustion and shallow melting depth, especially suitable for welding thin plates.
3. Easy operation, all position welding, single side welding and double side forming can be realized.
4. The weld formation is beautiful without splashing.

Precautions for product use

1. Protective gas: pure Ar; flow rate: 9-14L/min when the current is 100-200A, 14-18L/min when the current is 200-300A.

2. Tungsten electrode extension length: 3-5mm; arc length: 1-3mm.

3. The wind speed is limited to ≤1.0m/s; it is recommended to pass argon protection on the back of the welding area.

4. In welding, the magnitude of the welding line energy directly affects the mechanical properties and crack resistance of the weld metal, and more attention should be paid to it.

5. Make sure to remove the rust layer, moisture, oil, dust, etc. on the welding part.

The above suggestions are for reference only, and the actual situation shall prevail in the specific operation. If necessary, process qualification should be carried out before determining the welding plan.
