• ERNiCu-7 Details

  
  
  

  ERNiCu-7 is a commonly used filler metal in the welding of Monel 400 pipeline materials. It is designated as UNS N04060, also known as Monel 60, with a nominal composition of 65Ni-30Cu-3Mn-2Ti. ERNiCu-7 bare electrode/electrode can be used for GTAW (TIG), GMAW, SAW, and PAW processes, for welding Monel 400 (UNS N04400) materials of ASTM B127 (plate) and ASTM B163 (seamless pipe), ASTM B165 (seamless pipe), and ASTM B164 (bar, bar, and wire). Add titanium content through these welding processes to control porosity. The weld metal has similar characteristics to Monel 400. It has good strength and corrosion resistance in many media, including seawater, salt, and reducing acid.

  Welding precautions for ERNiCu-7 nickel copper alloy welding wire:
  

  1. The welding area must be thoroughly cleaned of surface impurities such as oil stains, rust, and moisture.

  2. When welding, small line energy should be used, and it is recommended to use a lower interpass temperature.

  3. The purity of the argon gas used should be above 99.99% and the gas flow control should be appropriate. Usually, when the welding current is 100-200A, the gas flow rate is about 10-15L/min.

  4. During welding, appropriate wind protection facilities must be in place, otherwise the protective gas is susceptible to the influence of wind, resulting in poor gas protection and deterioration of the weld bead, leading to the occurrence of pores.

  5. Properly select the nozzle and control the appropriate extension length of the tungsten electrode.
