Isethulo somkhiqizo:
'U' ukugoba kwenziwa inqubo yokusebenza ebandayo.
Ukugoba u-'U' kwenziwa kurediyasi edingekayo ngokwemidwebo yamakhasimende.
Ingxenye yokugoba kanye nomlenze wamayintshi ayisithupha ingcindezi ekhululwe ukushisisa ukumelana.
Igesi ye-inert (i-Argon) idlula kuyo ngezinga lokugeleza elidingekayo ukuze kugwenywe i-oxidation ku-ID.
Irediyasi ihlolelwa i-OD yayo kanye nokuncipha kodonga ngokucaciswa okunconyiwe.
Izakhiwo ezibonakalayo kanye nesakhiwo esincane kuhlolwa endaweni emithathu ehlukene.
Ukuhlolwa okubonakalayo kokuphaphatheka nokuqhekeka kwenziwa nge-Dye Penetrant Test.
Ishubhu ngalinye libe selihlolwa i-hydro ngengcindezi enconyiwe ukuze kubhekwe ukuvuza.
Ukuhlolwa kwebhola likakotini kwenziwa ukuhlola ukuhlanzeka kwe-ID yeshubhu.
Ngemuva kwalokho zifakwe emanzini anosawoti, zomisiwe, ziphawulwe futhi zipakishwe.
