为解决螺旋埋弧焊管传统一步法工艺生产效率低下、质量不稳定等问题,结合企业现有生产设备,根据产品特点,对生产线进行了预精焊工艺改造,研制了一种螺旋埋弧焊管精焊工作站,大幅度提高了产品质量和生产效率,满足了生产需求,同时为螺旋焊管精焊设备的国产化做了有益的尝试。 In order to solve the problems of low production efficiency and unstable quality in the conventional one-step process of spiral submerged arc welded pipe, the pre-smelting process of the production line was modified according to the existing production equipment of the submerged- Welding workstations, a substantial increase in product quality and production efficiency, to meet the production needs, at the same time for the spiral welded pipe welding equipment localization made a useful attempt.
