The cladding on the valves produced by overlay welding is to be tested for bonding flaws and inclusions.
對閥門堆焊的覆蓋層進行粘接缺陷和夾雜物的檢測
Solution:方案

Immersion testing mostly using only one track.
水浸法檢測大部分時候只用一個方向就可以
In case of larger welding widths the probe should be shiftable to enable more than one track.
對于較大的焊縫寬度，探頭應可以移動以至于能從多個方向檢測

Remark:
注意
When testing smaller numbers of valves, e.g. large diesels, manual testing can be carried out in the direct contact mode.
當檢測閥門數(shù)量較少時，例如大的柴油機，手動直接接觸法可以使用
