Vertical plate welding using double bevel joint |
摘要 |
A method is provided of vertical gas metal-arc two-sided welding of thick plate in a single welding pass on each surface of the plate. The method includes providing a first weld groove on one surface of the plate into which a weld bead is deposited in a single pass. Thereafter, a second weld groove is formed on the opposite surface of the plates by removing base plate material along the joining line to a depth extending at least to the first weld bead penetrating from the welding pass in the first weld groove. The plates are further joined together by depositing a weld bead in a single pass along the second welding groove. The welding is provided by impressing a direct electric current of from 290 to 420 amperes between an electrode and the plates shielded primarily by argon gas. A metal article and a welded joint are also provided.
