- Ukubaluleka koMlinganiselo wangoku: Umlinganiselo wangoku ubalulekile kwi-welding ye-nut spot njengoko ichaphazela ngokuthe ngqo ubushushu obuveliswa ngexesha lenkqubo ye-welding.Ukubeka iliso kwi-welding current ivumela ulawulo oluchanekileyo kunye nokulungelelaniswa, ukuqinisekisa ukuhambelana kunye nomgangatho ophezulu we-welds.Umlinganiselo ochanekileyo wangoku ukwanceda ukuchonga nakuphi na ukutenxa okanye ukungahambi kakuhle okunokuthi kuchaphazele ingqibelelo ye-weld, evumela ukuba kuthathwe amanyathelo okulungisa ngokukhawuleza.
- Isixhobo soVavanyo lwangoku: Isixhobo sovavanyo lwangoku sisixhobo esibalulekileyo sokulinganisa i-welding yangoku kumatshini we-welding nut spot.Yenzelwe ukubonelela ngokuchanekileyo kunye nokufundwa kwexesha langempela lombane ojikelezayo kwisiphaluka se-welding.Ezi zixhobo zikholisa ukubonisa isiboniso sedijithali ukwenzela ukufunda lula kwaye zibonelela ngeendidi ezahlukeneyo zokulinganisa ukulungiselela iimfuno ezahlukeneyo ze-welding.
- Iimpawu zeZixhobo zoVavanyo lwangoku: a.Umlinganiselo ochanekileyo: Izixhobo zokuvavanya zangoku zenzelwe ukubonelela ngokuchaneka okuphezulu kunye nesisombululo, ukuvumela umlinganiselo ochanekileyo wangoku ngexesha lenkqubo ye-welding.b.Iindlela zokuLinganisa ezininzi: Ezi zixhobo zibonelela ngeendlela ezahlukeneyo zokulinganisa, ezifana ne-current ngqo (DC) kunye ne-alternating current (AC), ukulungiselela izicelo ezahlukeneyo ze-welding.c.Uvavanyo olungaPhambilili: Uninzi lwezixhobo zokuvavanya zangoku zisebenzisa iindlela zokulinganisa ezingabonakaliyo, ukuphelisa isidingo sokuphazamisa i-welding circuit okanye ukuphazamisa inkqubo ye-welding.d.Iimpawu zoKhuseleko: Izixhobo zokuvavanya zangoku zixhotyiswe ngeempawu zokhuseleko ukukhusela umqhubi kunye nesixhobo, kubandakanywa ukugquma, ukukhuselwa ngokugqithisileyo, kunye nokufumanisa i-short-circuit.e.Ukurekhodwa kwedatha kunye noHlalutyo: Ezinye izixhobo eziphambili zibonelela ngezakhono zokungena kwedatha, ukuvumela ukurekhoda kunye nohlalutyo lokufundwa kwangoku ngexesha.Le datha ingasetyenziselwa ukulungiswa kwenkqubo, ukulawula umgangatho, kunye nokusombulula ingxaki.
- Izibonelelo zeZixhobo zoVavanyo lwangoku: a.Ukuqinisekiswa koMgangatho: Umlinganiselo ochanekileyo wangoku uqinisekisa ukuba inkqubo ye-welding isebenza ngaphakathi kweeparitha ezifunwayo, okubangelwa ukuhambelana okuhambelanayo kunye nomgangatho ophezulu we-welds.b.Ukulungiswa kweNkqubo: Ngokubeka iliso kwi-welding yangoku, abaqhubi banokuchonga nayiphi na inguqu okanye izitenxo kwaye benze uhlengahlengiso oluyimfuneko ukuze kuphuculwe inkqubo ye-welding yokuphucula ukusebenza kakuhle kunye nokusebenza.c.Ukusombulula iingxaki kunye noLondolozo: Izixhobo zovavanyo lwangoku zinceda ekuxilongeni nasekuxazululeni imiba ye-welding ngokubonelela ngengqiqo ekuhambeni kwangoku kunye nokufumanisa naziphi na iziphazamiso ezinokubonisa ukungasebenzi kakuhle kwesixhobo okanye ukunxitywa kwe-electrode.d.Ukuthotyelwa nokuBhaliswa: Iirekhodi zangoku zemilinganiso zisebenza njengamaxwebhu abalulekileyo okuthotyelwa kwemigangatho nemimiselo yoshishino, kunye nophicotho lolawulo lomgangatho kunye neenjongo zokuqinisekisa i-weld.
Izixhobo zangoku zokuvavanya zidlala indima ebalulekileyo ekuqinisekiseni ukuchaneka, ukuthembeka, kunye nomgangatho weenkqubo ze-nut spot welding.Ngokulinganisa ngokuchanekileyo i-welding current, ezi zixhobo zibonelela ngolwazi oluxabisekileyo lokuphucula inkqubo, ukulungisa iingxaki, kunye nokuqinisekiswa komgangatho.Utyalo-mali kwizixhobo zokuvavanya ezikumgangatho ophezulu zenza ukuba abaqhubi bafezekise i-welds engaguqukiyo kwaye ethembekileyo, ukuphucula imveliso, kunye nokugcina ukuthotyelwa kwemigangatho yoshishino.
