HS114 cobalt base surfacing wire
Description:
HS114 Cobalt-based welding wire High-carbon Co-Cr-W alloy welding wire, wear resistance, corrosion resistance. But poor impact toughness.
use:
Mainly used for roller bit bearings, rotating blades and other parts of the boiler surfacing

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.
