摘　　要：采用高效药芯焊丝CO2气体保护焊进行了低压薄壁容器筒体纵缝机动焊的单道单面焊双面成形焊接工艺试验研究,结果表明,焊缝成形美观,焊接接头力学性能良好,RT射线结果合格,能够满足容器设计要求。将该焊接工艺应用到低压薄壁容器的焊接,简化了焊接工序,提高了生产效率,为以后类似低压薄壁容器焊接提供了一些借鉴。Welding with flux cored wire CO2 gas shielded are welding, to test the single side welding molding welding process for low pressure container tube longitudinal seam mobile wehling, weht forming is good, the mechanical properties of welded joints is good, RT ray result is qualified. And it can fully meet the design requirements of the container. The welding process is simplified, the production efficiency is improved. This article provides the reference for future similar wehling pressure container.
