3. Description and Applications

1. ERNiCrCoMo-1 is a nickel-chromium-cobalt-molybdenum alloy welding wire.

The deposited weld metal offers excellent elevated-temperature strength, corrosion resistance, and metallurgical stability.

2. Suitable for welding low-carbon nickel-chromium-cobalt-molybdenum alloys, weld overlay on steel, and joining dissimilar high-temperature alloys.

X-ray radiographic inspection: Grade I

4. Available Diameters

	MIG
Diameter (mm)	1.0、1.2、1.6

5. Welding Precautions

1. Remove all oil, rust, lubricants, moisture, marker ink, and other surface contaminants from the weld area before welding.

2. Keep heat input as low as practicable to reduce the risk of hot cracking. A low interpass temperature, preferably below 100°C, is recommended.

3. For outdoor welding, provide wind protection when wind speed exceeds 1.5 m/s; inadequate shielding gas coverage may cause weld bead deterioration and porosity.
