介绍相控阵超声检测(PAUT)对T形接头焊缝依据断裂力学验收标准做工艺评定试验的方法。用DNV RP-F118[1]作为缺陷检测和定量评价的导则。本文简要介绍评定过程,概述验证结果,并给出模化验证示例,期盼为国内开展PAUT工艺评定提供有用借鉴。
This paper introduces the method of phase - controlled array ultrasonic testing (PAUT) to make process qualification test on T - joint weld according to the acceptance standard of fracture mechanics. Use DNV RP-F118 [1] as a guideline for defect detection and quantitative evaluation. This article briefly introduces the evaluation process, summarizes the verification results, and gives examples of mold verification, looking forward to provide a useful reference for the domestic PAUT process evaluation.
