When welding with ceriated tungsten, which material requires the highest amperage?

Ceriated tungsten electrodes are specifically designed for use in welding processes that require higher amperage settings. They exhibit excellent performance across a range of materials due to their ability to maintain a stable arc at elevated temperatures. Among the materials listed, nickel requires the highest amperage during GTAW.

Welding nickel often involves thicker sections and requires significant heat input to achieve proper penetration and fusion. The high thermal conductivity and melting point of nickel make it essential to use a higher amperage to ensure the weld pool remains fluid and manageable. The ceriated tungsten's properties help maintain a consistent arc and allow for the necessary heat to be effectively applied.

This characteristic makes ceriated tungsten particularly suitable for applications involving nickel, which has distinct melting and welding characteristics compared to other materials such as carbon steel, titanium, and stainless steel. Each of these may have varying amperage requirements, but for achieving optimal results with nickel, the higher amperage capability of ceriated tungsten is key.
