When selecting electrode materials for dual pulse lithium battery spot welding machines, multiple factors need to be considered. Firstly, electrode materials should have good electrical and thermal conductivity to ensure effective transfer of electrical energy and heat during the welding process.

Secondly, electrode materials should have high wear resistance and corrosion resistance to ensure that they are not easily damaged or corroded during long-term use.

In addition, when selecting electrode materials, their compatibility with welding materials should also be considered to ensure good welding results. Common electrode materials include copper, molybdenum, tungsten and other metal materials, among which copper is the most commonly used choice due to its good conductivity and thermal conductivity.

In general, the selection of electrode materials requires comprehensive consideration of factors such as conductivity, thermal conductivity, wear resistance, and corrosion resistance to ensure the stability and welding quality of the dual pulse lithium battery spot welding machine.
