H0Cr19Ni12Mo2
Description:
The main wire is 18Cr-12Ni-2Mo, stainless steel TIG wire. Weld metal corrosion, heat, cracking performance. Because of Mo, for acetic acid, sulfurous acid, phosphoric acid and salt corrosion resistance.
use:
For carbon steel and low alloy steel structure of the flat welding, fillet welding, such as 16Mn, 09Mn2Si and ships with A, B, D, E grade steel.

Precautions:
1. Protective gas: pure Ar; flow: 9 ~ 14L / min at current of 100 ~ 200A and 14 ~ 18L / min at current of 200 ~ 300A.
2. Tungsten extension length: 3 ~ 5mm; arc length: 1 ~ 3mm.
3. Wind speed limit ≤1.0m / s; it is recommended to pass argon gas protection on the back of welding area.
4. In welding, the size of the welding wire energy directly affects the mechanical properties of the weld metal and crack resistance, should pay more attention.
5. Welding parts of the rust layer, moisture, oil, dust, etc. in addition to net.
The above suggestions are for reference only, in the specific operation to the scene prevail. If necessary, process assessment and then determine the welding program.
