摘要
介绍了LNG项目中应用的Inconel625合金与低温碳钢，分析了母材的焊接性，就钨极氩弧焊（GTAw）＋焊条电弧焊（SMAW）进行焊接工艺评定，对相应的结果进行了分析，给出了焊接过程中的质量控制措施，开发成功GTAw＋sMAw的焊接工艺，积累了相关经验。
The Inconel 625 alloy and low temperature carbon steel （LTCS） used in Liquified-Natural Gas（LNG） were introduced. The weldability of parent material was analyzed, and the controlling measures of welding quality were given. The welding procedure qualification （WPQ） was carried out with GTAW＋ SMAW process, and welding procedure was achieved successfully through the analyzing of corresponding WPQ results, and also the relevant experiences were accumulated.
