H1Cr13
Description:
The main components of wire is 13Cr, martensitic stainless steel TIG wire. Smooth welding, beautiful appearance, deposited metal corrosion resistance is good.
use:
Often used in wear-resistant corrosion resistant martensitic stainless steel welding, such as 12Cr13 (SUS 410).

Welding current (A) | 50 ~ 100 | 100 ~ 200 | 200 ~ 300 | 300 ~ 400 |
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.
