AWS 5.14 ERNi-1

ERNi-1 is a type of nickel welding wire, with the chemical composition code NiTi3. It has excellent welding process performance, and the weld seam has a beautiful shape. The deposited metal also possesses excellent comprehensive mechanical properties.
Application:

It is mainly used for welding industrial pure nickel.

Notes on usuage:

1. The welding area must be thoroughly cleaned of surface impurities such as oil, rust, and moisture.
2. During welding, use a small line energy and recommend a lower inter-pass temperature.
3. The purity of the argon gas should be above 99.99% and the gas flow rate should be appropriately controlled. Generally, when the welding current is between 100-200A, the gas flow rate is approximately 10-15L/min.
4. During welding, appropriate wind protection facilities must be in place. Otherwise, the protective gas is prone to be affected by the wind, resulting in poor gas protection and deterioration of the weld bead, leading to gas porosity.
5. Select the appropriate nozzle and control the appropriate extension length of the electrode appropriately.
