摘　　要：高强钢管道在线焊接对管道抢修质量和安全服役有重要影响。分析了高强钢管道在线焊接存在的烧穿和氢致开裂等问题,梳理了影响高强钢焊接工艺评定的关键技术点,重点研究了环境、碳当量、壁厚、压力、介质流速、焊条选型等9个关键技术点对焊接工艺评定的影响,提出了针对高强钢管道焊接工艺评定的研究建议,为制定高强钢管道焊接工艺评定提供参考。On line welding of high strength steel pipeline has important influence on the urgent repair quality and security service of pipeline. Problems such as burning through and hydrogen induced cracking in welding process of high strength steel pipeline are ana- lyzed. The key factors influencing the welding process evaluation of high strength steel are combed, and the effects of 9 key factors, such as the environment, carbon equivalent, wall thickness, pressure, flow rate of the medium and the type of electrode, on the evaluation of the welding process are studied. Some suggestions for the evaluation of welding process of high strength steel pipeline are put forward, which can provide reference for the evaluation of welding process of high strength steel pipeline.
