Precautions:

1. Protection of gas: the use of pure Ar; flow: current in the 100 ~ 200A 9 ~ 14L / min, the current in the 200 ~ 300A 14 ~ 18L / min.

2. Tungsten pole extension length: 3 ~ 5mm; arc length: 1 ~ 3mm.

3. Wind speed limit of ≤ 1.0m / s; Proposed in the welding area on the back of the argon protection.

4. In the welding, the welding line energy directly affects the size of the weld metal mechanical properties and crack resistance, etc., should be more attention.

5. The welding parts of the rust layer, moisture, oil, dust, etc. in addition to the net.The above recommend ations are for reference only, in the specific operation of the prevailing situation prevail. If necessary, first process evaluation and then determine the welding program.
