Schematic design of a submerged arc welding system

Usually it is welded with direct current with the positive pole at the wire electrode. Other polarities are also possible. The power supplies are usually rectifiers. It has to be considered that, due to the high stage of mechanism, there are high intensities of current placed at disposal at a duty cycle of 100 %. [...]

General Introduction to Submerged Arc Welding

General Introduction to Submerged Arc Welding

The arc burns invisibly between a melting electrode and the work piece, or between two melting electrodes. Arc and welding zone are covered by a layer of flux. The weld pool is protected from the admission of the atmosphere by slag developed by the flux. The shown cross-section shows that the weld pool is covered [...]
