A welding electrode has a body having a shank and a contact region for placement against a workpiece during welding. A portion of the body may be formed on a parabolic profile. A coating is formed on the contact region. The coating may have a first layer, and a second layer formed over the first layer. The first and second layers may have different compositions. The electrode may have internally formed cooling finwork for interaction with a liquid cooling system.
