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

Immersion testing mostly using only one track.
水浸法檢測(cè)大部分時(shí)候只用一個(gè)方向就可以
In case of larger welding widths the probe should be shiftable to enable more than one track.
對(duì)于較大的焊縫寬度，探頭應(yīng)可以移動(dòng)以至于能從多個(gè)方向檢測(cè)

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(dāng)檢測(cè)閥門數(shù)量較少時(shí)，例如大的柴油機(jī)，手動(dòng)直接接觸法可以使用
