Abstract
A welding method using embodiments of electrodes () with coaxial power feed. The electrode comprises a metal cylinder () defining a hollow core (). The hollow core provides a conduit for delivering core feed materials () therebetween via a delivery means (). The cylinder may be formed of pure metals or extrudable alloys for forming a desired superalloy material composition; while the delivered core feed materials comprise a balance of compositional constituents for forming the desired superalloy material composition. The resulting deposit achieves the desired superalloy composition as a result of at least a combination of the cylinder materials and core feed materials. The electrode may further include a flux coating () surrounding the cylinder. The flux material may also contribute to the desired superalloy composition as a result of the weld operation.
