中文摘要：采用药芯焊丝对奥氏体不锈钢管道进行打底焊接、MAG填充及盖面焊、立向上水平固定全位置焊接，具有工艺性能良好、操作方便、焊接质量稳定的特点，在复杂的现场管道施工及高空作业时其优点更为突出。
英文摘要：Flux-cored wire was applied to back-weld austenitic stainless steel pipe, MAG was used for filling and cosmetic welding, horizontal fixed round welding in vertical. The welding process has the characteristics of good performance, easy operation and stable quality, especially for the operation of the complicated pipelines and upper air operation.
