摘要
针对海上浮式生产平台高强度大尺寸铸钢件的焊接难点,根据焊接工艺规程(Welding Procedure Specification,WPS)进行铸钢件焊接工艺评定(Welding Procedure Qualification,WPQ)。采取一系列有效措施进行铸钢件焊接质量控制,采用相控阵超声波检测(Phased Array Ultrasonic Testing,PAUT)进行焊缝质量验收,最终获得良好的焊缝质量。研究结果可为海洋工程同类型材料焊接质量控制提供借鉴。
In view of the welding difficulties of high-strength and large-sized cast steel parts for offshore floating production platform,the Welding Procedure Qualification(WPQ)of cast steel parts is conducted in accordance with the Welding Procedure Specification(WPS).The welding quality control of cast steel parts is conducted with a series of effective measures,the weld quality acceptance is conducted with the Phased Array Ultrasonic Testing(PAUT),and finally the good weld quality is obtained.The research results can provide reference for the welding quality control of the same type of materials for offshore engineering.
