Nickel and nickel alloy welding rods are special welding rods specifically used for welding nickel and nickel alloys. It can be used not only for welding of the same metal, but also for welding and surfacing of dissimilar metals. Due to the tendency of nickel and nickel alloys to overheat during welding, resulting in grain growth and strong sensitivity to porosity, special care should be taken during operation.
To ensure welding quality, a smaller welding current should be used to avoid material overheating. Meanwhile, controlling the arc length is crucial, as excessively long arcs can increase the risk of porosity. In addition, the control of interlayer temperature is also crucial, as a low interlayer temperature can help avoid welding defects. In practical operation, welders need to flexibly adjust parameters according to specific situations to ensure the smooth progress of the welding process.
