摘要
介绍了自保护药芯焊丝半自动焊与焊条电弧焊联用的焊接工艺。由于此种焊接工艺具有生产成本低、生产效率高、一次焊接合格率高等特点,因此在大、中型直径管道施工中具有较好的推广应用价值。
A combined welding technique, which is the application of semiautomatic welding protected by flux cored wire combined with electrical rod arc welding in the long distance transmission pipeline, is introduced in this article. The technique is worthy of being popularized in the construction of pipelines with large or middle diameter because of its low cost, high efficiency and high qualified rate.
