The cladding on the valves produced by overlay welding is to be tested for bonding flaws and inclusions.
对阀门堆焊的覆盖层进行粘接缺陷和夹杂物的检测
Solution:方案
Immersion testing mostly using only one track.
水浸法检测大部分时候只用一个方向就可以
In case of larger welding widths the probe should be shiftable to enable more than one track.
对于较大的焊缝宽度，探头应可以移动以至于能从多个方向检测
Remark:
注意
When testing smaller numbers of valves, e.g. large diesels, manual testing can be carried out in the direct contact mode.
当检测阀门数量较少时，例如大的柴油机，手动直接接触法可以使用
