奥氏体不锈钢焊缝,由于组织粗大,一般认为使用通常的横波斜射法探伤是很困难的. 日本木村胜美等根据试验研究,在《非破坏检查》杂志上载文认为,如选用合适的探头,能够提高信噪比.可选用的探头型式如下: (1)纵波斜射式探头:(2)聚焦式或分割式探头;(3)高分辨力式探头. Austenitic stainless steel weld, due to coarse tissue, is generally believed that the use of the usual shear wave oblique test is very difficult.Japakura Kimura Japan based on experimental studies, in the “non-destructive inspection” magazine that if the use of the appropriate probe , Can improve the signal to noise ratio.The optional probe types are as follows: (1) longitudinal wave oblique probe: (2) focus or split probe; (3) high resolution probe.
