H1Cr18Ni9
Description:
The main wire is 18Cr-9Ni, stainless steel TIG wire. Smooth welding, smooth and smooth weld, deposited metal corrosion resistance.
use:
Widely used in food machinery, medical equipment, fertilizer equipment, textile machinery and other components such as 12Cr18Ni9 (SUS 302) welding of materials, or similar base metal austenitic stainless steel welding.

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.
