铸件-超声波探伤-第三部分:球墨铸铁件 a — Scanning position A(探测位置A) b — Scanning position B(探测位置B)
c — A scan from scanning position A(在探测位置A处所得波形) e — A scan from scanning position B(在探测位置B处所得波形)
Dimension in through-wall direction d=t (s1+s2)
总壁厚方向的尺寸d=t (s1+s2)
Where(式中):
s1, s2 are the lengths of the sound-beam paths(s1, s2为声波束路径的长度)
t is the wall thickness(t为壁厚)
