Abstract
A continuous welding electrode suitable for short circuit welding is provided. The electrode has a continuous metal core with a welding flux material coated on its entire outer surface and circumscribing gaps are formed at regular interval over its entire length to expose a portion of the metal core. The gaps are adaptable for applying the welding current to the electrode in the welding operation. The melting temperature of the welding flux material is about 0.8 to 0.9 times the melting temperature of the metal core; and the unit weight of the welding flux material coating is about 0.37 to 0.48 times the unit weight of the metal core.
