摘要: 某成品油管道换管改造中，需采用手工下向焊工艺，该工艺焊接效率高、操作简单，但根焊易引起裂纹。通过分析影响该工艺焊接质量的原因，制定出符合施工现场实际的质量保证措施，确保改造工作顺利完成。
Abstract: In the pipeline exchange and transformation of a Product Oil Pipeline, the technology of manual downward welding was needed; the technology was high efficiency in welding with easy operation, but cracks were easily induced in root welding. By analyzing the causes of affecting the welding technology, measures are provided for ensuring quality of field welding and as well as ensuring the smooth implementation of the transformation.
