Ukubona umhlwa kombhobho kubhekiselele ekubhaqweni kombhobho ongaphakathi ngenjongo yokubona ilahleko yesinyithi enjengombhobho wodonga lomhlwa. Indlela esisiseko esetyenziselwa ukuqonda umonakalo wepayipi kwinkonzo kwindawo yokusebenza kunye nokuqinisekisa ukuba iziphene kunye nomonakalo zifunyenwe ngaphambi kokuba iingxaki ezinzulu zenzeke kumbhobho.

Kwixesha elidlulileyo, indlela yendabuko yokubona umonakalo wepayipi yayikukuhlolwa kokumba okanye uvavanyo loxinzelelo lwepayipi. Le ndlela ibiza kakhulu kwaye ifuna ukuvalwa. Okwangoku, ii-corrosion detectors zisebenzisa itekhnoloji yokuvuza kwamagnetic kunye netekhnoloji ye-ultrasonic ingasetyenziselwa ukubona ubungakanani kunye nendawo yomonakalo onje ngemingxuma ye-corrosion, i-stress corrosion cracks, kunye nokuqhekeka kokudinwa.
