Cad Welding Connection is the accepted method of attachi
ng Cathodic Protection leads to pipes (Steel or cast iron), tanks and structures.
Cad Welding Connections is a function weld of the conductor to the surface. Therefore no galvanic corrosion can occur at the interface. (with Mechanical Connections, Surface Contacts are present, and can corrode resulting in a less effective current path)
Cad Welding Connections for Cathodic Protection use a special alloy to provide Minimum heat effect on the steel, especially important on thin wall, high stress pipes.
Cad Welding Connections are also used for header Cable taps, Conductor splices and terminations and ground rod connection.
