Golden Bridge ERNiCr-3 (JQ-MGNiCr-3) MIG Welding Wire
SKU:JQ-MGNICR-3-030-02.2
JQ-MGNiCr-3
MGNiCr-3 is a MIG welding wire. The bead has good crack resistance and excellent corrosion resistance.
The product is applicable for welding nickel-based and iron-nickel-based high-temperature corrosion-resistant alloys such as Inconel600 and Incoloy800, and can also be used for welding dissimilar steels.

1. Before welding, impurities such as pollutants and oxides on the welding edge of the work piece and the surface of the welding wire must be cleaned;
2. During the welding process, the weld gap should be cleaned in time to prevent slag inclusion;
3. Operating with small heat input as possible, and keeping the gap temperature below150℃.
