Emva kokugqiba inkqubo ye-welding usebenzisa umatshini we-welding welding, kubalulekile ukwenza uhlolo lwe-post-weld ukuqinisekisa umgangatho we-weld kunye nokuthobela imigangatho ethile.Iindlela ezininzi zokuhlola zisetyenziselwa ukuvavanya ingqibelelo kunye nokomelela kwamalungu e-weld.Eli nqaku libonisa isishwankathelo seendlela ezahlukeneyo zokuhlola ezisetyenziselwa uviwo lwe-post-weld kwimisebenzi ye-nut spot welding.
- Ukuhlolwa okubonakalayo: Ukuhlolwa okubonakalayo yeyona ndlela isisiseko kunye neyokuqala yokuvavanya umgangatho we-weld.Umhloli onamava uvavanya amajoyinti e-weld esebenzisa iliso lenyama ukuze abone iziphene ezibonakalayo ezifana nezitenxo zomphezulu, ukufana kwee-weld bead, kunye neempawu zokudibanisa okungaphelelanga okanye i-porosity.Le ndlela yokuhlola ingonakalisi ibonelela ngengxelo ebalulekileyo kwimbonakalo ye-weld iyonke kwaye ingabonisa ubukho beziphene ezinokubakho.
- Iindlela zoVavanyo olungaNciphisi (NDT): a.Uvavanyo lwe-Ultrasonic (UT): I-UT isebenzisa amaza omsindo we-high-frequency ukuze ihlole i-welds yeziphene zangaphakathi.Iyakwazi ukuchonga ukungaqhubeki, njengokuqhekeka okanye ukungabikho kokudibanisa, ngaphakathi kwe-weld joint ngaphandle kokubangela umonakalo kwicandelo.I-UT iluncedo ngakumbi ekuboneni iziphene ezifihliweyo kwii-welds ezibalulekileyo.
b.Uvavanyo lweRadiographic (RT): I-RT ibandakanya ukusetyenziswa kwe-X-rays okanye imisebe ye-gamma ukufumana imifanekiso yesakhiwo sangaphakathi se-weld joint.Ubuchwephesha buvumela abahloli ukuba bachonge iziphene zangaphakathi, i-voids, kunye ne-inclusions enokuthi ingabonakali ngexesha lokuhlola okubonakalayo.
c.Uvavanyo lweMagnetic Particle (MT): I-MT isetyenziswa ikakhulu ukuhlola imathiriyeli ye-ferromagnetic.Ibandakanya ukusetyenziswa kwemagnethi kunye namasuntswana emagnethi kwindawo yeweld.Amasuntswana aya kuqokelelana kwiindawo ezineziphene, ezenza ukuba zibonakale lula.
d.Uvavanyo lwe-Liquid Penetrant Testing (PT): I-PT iqeshwe ukuchonga iziphene eziqhekeza phezulu kwizinto ezingenayo i-porous.Ulwelo lwe-penetrant lusetyenziswa kwi-weld surface, kwaye ukungena okugqithisileyo kuyacinywa.I-penetrant eseleyo ityhilwa ngokusetyenziswa komphuhlisi, iqaqambisa naziphi na iziphene zomhlaba.
- Uvavanyo olutshabalalisayo (i-DT): Kwiimeko apho umgangatho we-weld kufuneka uvavanywe ngokungqongqo, iindlela zokuvavanya ezonakalisayo zisetyenziswa.Olu vavanyo lubandakanya ukususa inxalenye ye-weld joint ukuhlola iimpawu zayo zomatshini kunye namandla.Iindlela eziqhelekileyo zeDT ziquka: a.Uvavanyo lwe-tensile: Ilinganisa ukomelela kunye nokudumba kwelungu le-weld.b.Uvavanyo lwe-Bend: Uvavanya ukuxhathisa kwe-weld ekuqhekekeni okanye ukwaphuka phantsi koxinzelelo lokugoba.c.Uvavanyo lweMacroscopic: Ibandakanya ukwahlula kunye nokupholisha i-weld ukuvavanya ubume bayo kunye nokungena kwe-weld.
Ukwenza uhlolo lwe-post-weld usebenzisa iindlela ezahlukeneyo kubalulekile ukuqinisekisa ukuthembeka kunye nomgangatho we-weld joints owenziwe ngumatshini we-nut welding.Ukudityaniswa kokuhlolwa okubonakalayo, iindlela zokuvavanya ezingonakalisi, kwaye, ukuba kuyimfuneko, uvavanyo olutshabalalisayo lubonelela ngemibono ebanzi kwintembeko ye-weld kunye nokuthotyelwa kwemigangatho yoshishino.Ngokuphumeza ezi ndlela zokuhlola, iingcali ze-welding zinokuqinisekisa ukhuseleko kunye nokusebenza kwamacandelo adibeneyo kwizicelo ezahlukeneyo.
