Emva kokugqitywa kwe-welding ye-nut projection, kubalulekile ukuqhuba uhlolo olunzulu ukuvavanya umgangatho we-weld kunye nokuqinisekisa ukuba ihlangabezana nemigangatho efunekayo. Eli nqaku lijolise kubuchule bokuhlola kunye neenkqubo eziqhelekileyo ezisetyenziswayo ukuvavanya ingqibelelo ye-weld kwi-welding ye-nut projection welding.
- Ukuhlolwa okubonakalayo: Ukuhlola okubonakalayo yindlela yokuqala nelula yokuvavanya umgangatho we-weld. Ibandakanya uviwo olubonakalayo lwendawo ye-weld kuzo naziphi na iziphene ezibonakalayo ezifana nokuqhekeka, i-voids, okanye i-fusion engaphelelanga. Umsebenzisi uhlola umphezulu we-weld joint, ubeke ingqalelo kwimilo kunye nobukhulu be-nugget, ubukho baso naziphi na izitenxo, kunye nokubonakala ngokubanzi kwe-weld.
- Ukuhlolwa koMda: Ukuhlolwa komgangatho kubandakanya ukulinganisa imilinganiselo engundoqo yejoyini ye-weld ukuqinisekisa ukuhambelana kwayo nokunyamezela okukhankanyiweyo. Oku kubandakanya ukulinganisa i-diameter kunye nobude be-weld nugget, ubude beprojection, kunye nejometri epheleleyo yejoyini. Imilinganiselo ithelekiswa nemilinganiselo efunekayo ukuqinisekisa ukubunjwa okufanelekileyo kwe-weld.
- Uvavanyo olungabhubhiyo (NDT): Ubuchule bokuvavanya obungonakalisi bunokubonelela ngolwazi oluxabisekileyo malunga nokunyaniseka kwangaphakathi kwe-weld ngaphandle kokwenza umonakalo kwi-joint. Iindlela eziqhelekileyo ze-NDT ezisetyenziswa kwi-welding ye-nut projection ibandakanya:
- Uvavanyo lwe-Ultrasonic (UT): Amaza e-Ultrasonic asetyenziselwa ukufumanisa iziphene zangaphakathi ezifana nokuqhekeka okanye i-voids ngaphakathi kwe-weld joint.
- Uvavanyo lweRadiographic (RT): I-X-rays okanye imisebe ye-gamma isetyenziselwa ukuvelisa imifanekiso ye-weld, evumela ukufunyanwa kweziphene zangaphakathi okanye ukudibanisa okungaphelelanga.
- Uvavanyo lweMagnetic Particle (MT): Amasuntswana omagnetic asetyenziswa kumphezulu we-weld, kwaye nakuphi na ukuvuza kwamagnetic okubangelwa ziziphene kuchongiwe kusetyenziswa izinzwa zemagneti.
- Uvavanyo lwe-Dye Penetrant Testing (PT): I-dayi ye-penetrant ifakwe kwi-weld ye-weld, kwaye naziphi na iziphene eziqhekezayo zibonakaliswe yidayi ephuma kwiiphene.
- Uvavanyo loomatshini: Uvavanyo lomatshini kubandakanya ukubeka ijoyinti ye-weld kwiimvavanyo ezahlukeneyo zoomatshini ukuvavanya amandla kunye nokuthembeka kwayo. Oku kunokubandakanya ukuvavanywa koxinzelelo, apho i-weld iphantsi kolawulo olulawulwayo lokutsala ukuvavanya ukuchasana kwayo nokwahlula. Olunye uvavanyo olunjengovavanyo lokugoba okanye uvavanyo lobulukhuni lunokubonelela ngolwazi oluxabisekileyo malunga neempawu zomatshini we-weld.
Ukuhlolwa kwe-post-weld kwi-weld projection welding idlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokuthembeka kwamalungu e-weld. Ngokusebenzisa uhlolo olubonakalayo, uvavanyo olungonakalisi, kunye nobuchule bokuvavanya oomatshini, abaqhubi banokuchonga naziphi na iziphene okanye izitenxo kwaye bathathe amanyathelo afanelekileyo okulungisa. Oku kunceda ukugcina ukuthembeka kunye nokusebenza kwee-weld joints, ukuqinisekisa ukuba bahlangabezana nemigangatho efunekayo kunye neenkcukacha.
