Meet: GB / T15620-2008 SNI6625 AWS A5.14 ERNICrMo-3 Description: ERNICrMo-3 is a nickel-chromium-molybdenum alloy TIG welding wire. With excellent welding performance, stable arc welding, beautiful weld appearance, good anti-porosity, weld metal has good heat resistance, corrosion resistance and excellent overall mechanical properties. Weld metal ray detection requirements: Ⅰ level Matters needing attention and operation points: 1, the weld should be completely removed oil, rust, moisture and other surface impurities. 2, welding, using a small line of energy, it is recommended to use a lower temperature between the road.
