由沪东造船厂研究的 FCB 法压力架式双丝单面埋弧自动焊工艺,于1987年12月由中国船舶工业总公司技术部组织召开了鉴定会与会的专家、教授和代表对此项工艺给予较高的评价。此 FCB 法是以12米长的压力架形式,配以专用的 MZ—2(1)×1500—JP_2型双丝埋弧自动焊机和专用焊剂焊接板厚为12～20毫米的一般船用钢板拼板工艺。该项工艺经多 By Hudong Shipyard research FCB method pressure frame double wire single-sided submerged arc automatic welding technology, in December 1987 by the China State Shipbuilding Corporation Technical Department held a meeting identified experts, professors and representatives of this Process to give a higher rating. The FCB method is based on a 12 m long pressure frame with a special MZ-2 (1) × 1500-JP_2 double wire submerged arc welding machine and a special flux for welding general marine steel plates with a thickness of 12 to 20 mm Puzzle craft. The process by much
