Kwilizwe lemveliso kunye nobunjineli, ukuwelda yinkqubo esisiseko esetyenziselwa ukudibanisa amaqhekeza amabini okanye ngaphezulu esinyithi. Enye into ebalulekileyo kule nkqubo kukwenziwa kwechibi leweld, elinika umdla ngakumbi xa kufikwa koomatshini bokuwelda amantongomane. Kweli nqaku, siza kuphanda kubuchwephesha bendlela eyenziwe ngayo i-weld pool kwaba matshini bakhethekileyo.
Ukuqonda Inkqubo ye-Nut Spot Welding
Phambi kokuba siphonononge ukubunjwa kwe-weld pool, makhe sizuze ukuqonda inkqubo ye-nut spot welding. Obu buchule busetyenziswa ikakhulu ukudibanisa i-nati okanye i-fastener kwi-workpiece yesinyithi, rhoqo kwi-automotive kunye ne-industrial applications. Yindlela ekhawulezayo nesebenzayo, eqinisekisa uqhagamshelo olukhuselekileyo olunokumelana nomthwalo omkhulu.
Indima yobushushu kunye noxinzelelo
Kwi-nut spot welding, izinto ezimbini eziphambili ezidlalwayo bubushushu kunye noxinzelelo. Umatshini usebenzisa umthombo wokushisa wendawo kwi-nut kunye ne-workpiece. Obu bushushu, obusoloko buveliswa ngumsinga wombane odlula kwizinto, bubangela ukuba isinyithi esikulo mmandla sinyibilike. Ngaxeshanye, uxinzelelo lusetyenziswa ukuqinisekisa unxibelelwano olufanelekileyo phakathi kwe-nut kunye ne-workpiece.
Ukuqulunqwa kwe-Weld Pool
Idama le weld, ummandla wesinyithi otyhidiweyo okhoyo ngexesha lenkqubo, isitshixo sempumelelo ye-nut spot weld. Idalwe xa umthombo wobushushu, ngokuqhelekileyo i-electrode, idibana ne-nut kunye ne-workpiece. Ubushushu bunyusa ngokukhawuleza ubushushu bentsimbi kule ndawo, bubangela ukuba bunyibilike.
Isinyithi esityhidiweyo siqokelela kwi-interface phakathi kwe nut kunye nomsebenzi. Eli linqaku elibalulekileyo kwinkqubo, njengoko kulapho kudityaniswa kwezi zinto zimbini kwenzeka. Idama kufuneka libe nobukhulu obufanelekileyo kunye nobushushu ukuze kuqinisekiswe i-weld eyomeleleyo, ehlala ixesha elide.
Ulawulo kunye nokuchaneka
Ubungakanani kunye nokumila kwe-weld pool ilawulwa ngononophelo kwi-nut spot welding. Ubude bexesha lokusetyenziswa kobushushu, ukusetyenziswa kwangoku, kunye noxinzelelo olusetyenzisiweyo zonke zidlala indima ekumiseleni iimpawu ze-weld pool. Injongo kukudala ichibi elilingana nobukhulu obufanelekileyo ukuququzelela ibhondi eyomeleleyo ngaphandle kwe-splatter egqithisileyo okanye ukugqwetheka.
Ukuqinisa kunye nokudibanisa
Emva kokuba i-weld pool yenziwe, ivumelekile ukuba ipholile kwaye iqiniswe. Njengoko isinyithi esityhidiweyo siqina, sidibanisa i-nut kwi-workpiece, ukudala ibhondi eyomeleleyo yomatshini. Olu nxulumano luphunyezwa ngenxa yokuba ezi zinto zimbini, kwiindawo zazo ezityhidiweyo, zixuba kwaye zidibanise kwinqanaba le-athomu. Njengoko zipholile kwaye ziqina, ngokufanelekileyo ziba yinto enye.
Kumatshini we-nut welding, ukubunjwa kwe-weld pool linyathelo elibalulekileyo ekudaleni uxhulumaniso olomeleleyo noluhlala luhleli phakathi kwe-nut kunye ne-workpiece yentsimbi. Ngolawulo oluchanekileyo lobushushu, uxinzelelo, kunye nexesha, abavelisi banokuqinisekisa ukuba i-weld pool yenziwe ngokuchanekileyo, okukhokelela ekudibaneni okuthembekileyo kunye nokuqina. Ukuqonda le nkqubo kubalulekile kwabo babandakanyeka ekusebenzeni kwesinyithi, ukuwelda, kunye nobunjineli, njengoko ixhasa izicelo ezininzi zemizi-mveliso, ngakumbi kumacandelo eemoto kunye neyokuvelisa.
