Kwindawo ye-medium-frequency spot welding ye-DC, indima yoxinzelelo lwe-welding ihlala ingumxholo obaluleke kakhulu. Eli nqaku lijonga ukubaluleka koxinzelelo lwe-welding, iziphumo zalo kwinkqubo ye-welding, kunye nezinto ezifuna ukuqwalaselwa ngenyameko.
I-Welding yinkqubo enzima ebandakanya ukudityaniswa kweziqwenga ezimbini zetsimbi ngokusetyenziswa kobushushu kunye noxinzelelo. Nangona ukubaluleka kobushushu kule nkqubo kuqatshelwa ngokubanzi, indima yoxinzelelo lwe-welding ihlala ingaphantsi. Kwi-medium-frequency spot welding ye-DC, uxinzelelo olusetyenziswayo ngexesha lenkqubo ye-welding inokuchaphazela kakhulu umgangatho kunye nokunyaniseka kwe-weld joint.
Esinye sezizathu eziphambili zokuba kutheni uxinzelelo lwe-welding lubalulekile yimpembelelo yalo kuqhagamshelwano lombane phakathi kwezinto zokusebenza. Kwi-medium-frequency ye-DC spot welding, ukuhamba rhoqo kwangoku ngokuthe ngqo kudlula kwiindawo zokusebenza, kudala ukuxhathisa kunye nokuvelisa ubushushu. Umgangatho woqhagamshelwano lombane phakathi kwee-workpieces uchaphazeleka ngokuthe ngqo kuxinzelelo olusetyenzisiweyo. Uxinzelelo olungonelanga lunokukhokelela ekudibaneni kombane okungalunganga, okukhokelela ekufudumezeni okungalinganiyo kunye nelungu le-weld elibuthathaka.
Ngaphezu koko, uxinzelelo lwe-welding ludlala indima ebalulekileyo ekufezekiseni i-weld nugget engaguqukiyo, eyidama lesinyithi elityhidiweyo elakhiwe kwindawo yokuwelda. Uxinzelelo lunceda ukuqinisekisa ukuba i-workpieces ibanjwe ngokuqinileyo, ivumela ukusabalalisa okufanayo kobushushu kunye noxinzelelo kwi-joint. Oku kufana kubalulekile ukuvelisa iiwelds ezomeleleyo, ezihlala ixesha elide ezihlangabezana nemigangatho yoshishino kunye neemfuno zokhuseleko.
Impembelelo yoxinzelelo lwe-welding ayiphelelanga kumgangatho we-weld joint. Kwakhona kuchaphazela ukusebenza kakuhle kwenkqubo ye-welding. Uxinzelelo olungonelanga lunokukhokelela kwixesha elide le-welding kunye nokunyuka kokusetyenziswa kwamandla, ekugqibeleni kuchaphazela indleko-ukusebenza kwe-welding.
Izinto ezininzi kufuneka zithathelwe ingqalelo xa kumiselwa uxinzelelo oluphezulu lwe-welding kwisicelo esinikiweyo. Ubukhulu bezinto eziphathekayo, uhlobo lwesinyithi oludityanisiweyo, ubungakanani be-electrode kunye nokumila, kunye noseto lomatshini we-welding zonke zidlala indima ekuchazeni iiparamitha zoxinzelelo ezifanelekileyo. Abaqhubi be-welding kufuneka baqeqeshwe ukuba baqaphele iimpawu zokungonelanga okanye uxinzelelo olugqithisileyo kwaye benze uhlengahlengiso oluyimfuneko ukufezekisa umgangatho ofunekayo we-weld.
Ukuqukumbela, uxinzelelo lwe-welding lubalulekile ngokungathandabuzekiyo kwi-medium-frequency spot welding ye-DC. Ichaphazela ngokuthe ngqo uqhagamshelwano lombane, i-weld nugget formation, kunye nokusebenza kakuhle kwenkqubo ye-welding. Ukufezekisa umgangatho ophezulu kunye nokuthembeka kwe-welds, abaqhubi be-welding kufuneka baqonde indima yoxinzelelo kunye nokusebenzisana kwayo kunye neeparitha ezahlukeneyo ze-welding. Ngokwenza njalo, banokuqinisekisa ukuba imisebenzi yabo ye-welding ihlangabezana nemigangatho efunekayo kwaye ivelise i-weld joints eqinile, ehlala ixesha elide.
