Ukuqinisekisa umgangatho wokuwelda amandongomane kubalulekile ekuphumezeni amakhonkco athembekileyo kunye nesakhiwo esinesandi koomatshini bokuwelda amandongomane.Eli nqaku libonisa iindlela ezahlukeneyo zokuhlola ezinokuthi zisetyenziswe ukuvavanya umgangatho we-nut welds.Ngokusebenzisa obu buchule, abavelisi banokuchonga naziphi na iziphene okanye ukungafezeki kwi-welds kwaye bathathe amanyathelo afanelekileyo okugcina imigangatho ephezulu ye-welding.
- Uhlolo oluBonakalayo: Ukuhlola okubonwayo yindlela esisiseko yokuvavanya inkangeleko iyonke kunye nemeko yomphezulu we-nut welds.Abahloli bahlola indawo ye-weld ukubona iimpawu zokuqhekeka, i-porosity, i-fusion engaphelelanga, okanye naziphi na iziphene ezibonakalayo.Le ndlela ifuna abasebenzi abanezakhono abaqeqeshelwe ukuqaphela ukungafezeki kwe-welding kunye nokutenxa kwiprofayili ye-weld efunwayo.
- Uvavanyo lwe-Dye Penetrant: Uvavanyo lokungena kwedayi yindlela yokuhlola engonakalisi esetyenziselwa ukufumanisa iziphene eziqhekeza umphezulu kwi-nut welds.Isisombululo se-penetrant sisetyenziswe kwi-weld surface, kwaye emva kwexesha elithile lokuhlala, ukungena okungaphezulu kuyasuswa.Umphuhlisi uyasetyenziswa ke, atsale nawuphi na umngeneleli obambeke kwiziphene, ezenza zibonakale.Le ndlela inokuchonga iintanda, i-porosity, kunye nezinye iziphene ezingaphezulu ezinokubeka esichengeni ingqibelelo ye-weld.
- Uvavanyo lweRadiographic: Uvavanyo lweRadiographic, olwaziwa ngokuba yiX-reyi okanye ukuhlolwa kweradiyographic, yindlela esetyenziswa ngokubanzi yokuvavanya imfezeko yangaphakathi yee-nut welds.I-X-ray okanye i-gamma-ray ray idluliswa kwi-weld, kwaye umfanekiso ophumelayo ubonisa ukungaqhubeki kwangaphakathi njenge-voids, inclusions, okanye ukungabikho kokudibanisa.Le ndlela ibonelela ngovavanyo olubanzi lwesakhiwo sangaphakathi se-weld kwaye isebenzayo ngokukodwa ekuboneni iziphene ezifihliweyo.
- Uvavanyo lwe-Ultrasonic: Uvavanyo lwe-Ultrasonic lusebenzisa amaza omsindo aphezulu aqhelekileyo ukuhlola i-nut welds yeziphene zangaphakathi.I-transducer ifakwe kwi-weld surface, ekhupha amaza e-ultrasonic asasaza nge-weld.Nakuphi na ukungahambi kakuhle, okufana ne-voids, ii-cracks, okanye ukungabikho kwe-fusion, kuya kubangela ukubonakaliswa okanye utshintsho kumaza e-ultrasonic, anokufunyanwa kwaye ahlalutywe.Uvavanyo lwe-Ultrasonic lubonelela ngolwazi oluxabisekileyo malunga nesakhiwo sangaphakathi se-weld kwaye inokubona iziphene ezinokuthi zingabonakali kwiso lenyama.
- Uvavanyo lwe-Tensile kunye ne-Bend: Uvavanyo lwe-Tensile kunye nokugoba kubandakanya ukubeka iisampuli zovavanyo ezikhutshwe kwi-nut welds ukuya kumandla omatshini.Uvavanyo lwe-tensile lulinganisa amandla e-weld ngokusebenzisa amandla okutsala de i-weld joint break, ngelixa uvavanyo lwe-bend luvavanya i-ductility ye-weld ngokugoba i-specimen yokuvavanya ukuchasana kwayo nokuqhekeka okanye ukuguqulwa.Olu vavanyo lubonelela ngedatha yobungakanani kwiipropathi zomatshini we-weld, njengamandla okuqina, ubude, kunye nokumelana nempembelelo.
Umgangatho we-nut welds kumatshini we-nut welding unokuvavanywa ngokufanelekileyo usebenzisa iindlela ezahlukeneyo zokuhlola.Ukuhlolwa okubonakalayo, uvavanyo lokungena kwedayi, uvavanyo lweradiyographic, uvavanyo lwe-ultrasonic, kunye nobuchule bokuvavanya oomatshini bubonelela ngolwazi oluxabisekileyo malunga nemeko yomphezulu we-weld, imfezeko yangaphakathi, kunye neempawu zoomatshini.Ngokuphumeza ezi ndlela zokuhlola, abavelisi banokuqinisekisa ukuba i-nut welds ihlangabezana nemigangatho yomgangatho ochaziweyo kwaye igalelo ekuveliseni iindibano ezinamandla nezithembekileyo.
