Ukuqinisekisa ukomelela kwewelding koomatshini bokuwelda bamandongomane kubalulekile ukuqinisekisa ukuthembeka kunye nokuqina kwamalungu adityanisiweyo. Kweli nqaku, siza kuphonononga iindlela zokuvavanya amandla okuwelda koomatshini bokuwelda bamandongomane. Ngokuqhuba iimvavanyo ezifanelekileyo, abavelisi banokuqinisekisa umgangatho kunye nokunyaniseka kwee-welds, okubenza bakwazi ukuhlangabezana nemigangatho efunekayo kunye neenkcukacha.
- Uvavanyo lwe-Tensile: Uvavanyo lwe-tensile yindlela esetyenziswa ngokubanzi yokuvavanya amandla e-welding ye-weld spot nut. Olu vavanyo lubandakanya ukufaka umthwalo we-axial kwi-joint welded de ufikelele ekuhlulekeni. Amandla aphezulu anyamezelwa yi-weld abonisa amandla ayo okuqina. Uvavanyo lwe-tensile lunokwenziwa kusetyenziswa izixhobo zokuvavanya ezikhethekileyo, njengomatshini wokuvavanya jikelele, olinganisa umthwalo kunye neempawu zokuguqulwa kwe-weld.
- Uvavanyo lwe-Shear: Uvavanyo lokucheba yenye indlela eqhelekileyo yokuvavanya amandla e-welding ye-weld spot nut. Kolu vavanyo, i-shear force isetyenziswe ngokuhambelana ne-weld interface ukumisela umthwalo omkhulu odibeneyo unokumelana phambi kokungaphumeleli. Uvavanyo lokucheba lufaneleke ngokukodwa usetyenziso apho i-weld ifumana kakhulu uxinzelelo lokucheba, olufana noqhagamshelo lwe-fasteners.
- Uvavanyo lwePeel: Uvavanyo lwe-Peel lusetyenziselwa ukuvavanya amandla e-welding yamalungu adityanisiweyo, afana nalawo akhiwe ngamandongomane e-welding kwiphepha lesinyithi. Olu vavanyo lubandakanya ukufaka umthwalo we-tensile perpendicular kwi-plane ye-joint, ebangela ukuba i-weld ihlukane. Amandla afunekayo ukuqalisa kunye nokusabalalisa i-peel ibonisa amandla e-weld. Uvavanyo lwe-Peel lunokwenziwa kusetyenziswa izixhobo ezikhethekileyo, ezifana ne-peel tester, elinganisa ukuxhathisa i-peel ye-weld.
- Uhlolo oluBonakalayo: Uhlolo olubonwayo ludlala indima ebalulekileyo ekuvavanyeni umgangatho kunye nentembeko yee-weld spot nuts. Abahloli bajonga ngokubonakalayo iiweld kwiziphene ezahlukeneyo, ezinje ngokudityaniswa okungaphelelanga, iporosity, iintanda, okanye isitshizi esigqithisileyo. Ukuhlolwa okubonakalayo kufuneka kwenziwe ngokwemigangatho emiselweyo kunye neenkcukacha zokuqinisekisa ukuvavanywa okuhambelanayo kwamandla we-welding.
- Uvavanyo olungangonakalisiyo (NDT): Iindlela zovavanyo ezingonakalisiyo, ezinje ngovavanyo lwe-ultrasonic okanye uvavanyo lweradiyographic, zinokuqeshwa ukuvavanya amandla e-welding ye-nut spot welds. Obu buchule busebenzisa ubuchwepheshe obuphezulu bokubona iziphene zangaphakathi okanye ukungahambi kakuhle kwi-weld, ukubonelela ngolwazi oluxabisekileyo malunga nomgangatho we-weld ngaphandle kokwenza umonakalo.
Ukuvavanya amandla okuwelda koomatshini bokuwelda bamandongomane kubalulekile ekuqinisekiseni ukuthembeka kunye nokuthembeka kwamalungu adityanisiweyo. Ngokusebenzisa iindlela ezinje ngovavanyo lokuqina, uvavanyo lokucheba, uvavanyo lwamaxolo, uhlolo olubonakalayo, kunye novavanyo olungonakalisi, abavelisi banokuvavanya amandla kunye nomgangatho we-welds. Oku kubavumela ukuba bahlangabezane nemigangatho efunekayo kunye neenkcukacha, ukubonelela ngokuzithemba ekusebenzeni kwezicelo ze-nut spot welding.
