海底管线环焊缝的双丝焊接及无损检测
Double Wire Welding and Automatic Ultrasonic Testing of Girth welds of Submarine Pipeline
【摘要】 介绍了双丝焊接技术和自动超声波检测技术在海底管线环焊缝焊接施工中的应用。指出双丝焊接技术不仅可以提高焊接效率和焊接质量,而且有利于改善焊接接头的拉伸性能和断裂韧性;自动超声波检测技术具有检测效率高和成本低的特点,可满足海底管线铺设的时效性要求和焊缝质量控制要求。
【Abstract】 Double wire welding and automatic ultrasonic testing(AUT) applied in construction of submarine pipeline were introduced.It indicated that double wire welding technique not only advanced the efficiency of welding and quality of weld seam but also improve the tensile strength and facture toughness of the welded joints.AUT has the characters of high efficiency and low costs of testing.So AUT can meet the requirement of real time and quality control of welds for the construction of submarine pipeline.
