Kwinkqubo ye-welding ye-intermediate frequency spot welder, ukuxhathisa kuhlanganiswe ukuchasana koqhagamshelwano phakathi kwe-welds, ukuchasana koqhagamshelwano phakathi kwee-electrode kunye ne-welds kunye nokumelana kwee-welds ngokwazo.Njengoko iqondo lokushisa linyuka, ubukhulu bokumelana buhlala buguquka.
Ngexesha le-welding, umahluko woxinzelelo lwe-electrode, yangoku kunye nezinto ezinokuthi zifakwe kwi-welding zonke zichaphazela utshintsho oluguqukayo lokumelana.Xa izixhobo zetsimbi ezahlukeneyo zidityanisiwe, ukuchasana okuguquguqukayo kutshintsha ngokwahlukileyo.Ekuqaleni kwe-welding, isinyithi kwindawo ye-welding ayincibiliki kodwa ishushu ngaphambili, kwaye ukuchasana koqhagamshelwano kwehla ngokukhawuleza.Njengoko iqondo lokushisa linyuka, ukunyuka kwe-resistivity kuyanda, ngelixa ukuchasana kuncipha ngenxa yokunyuka kwendawo yoqhagamshelwano ebangelwa ukufudumeza, apho ukwanda kwe-resistiveivity kunamandla, ngoko ke ijika liphakama.
Xa ubushushu bufikelela kwixabiso elibalulekileyo, ukukhula kokumelana kuncipha kwaye okuqinileyo kuba lulwelo.Ngenxa yokunyuka kwendawo yoqhagamshelwano ngenxa yokufudumeza ukuthambisa, ukuchasana kuyancipha, ngoko i-curve iyancipha kwakhona.Ekugqibeleni, ngenxa yokuba intsimi yeqondo lokushisa kunye nentsimi yangoku ngokusisiseko ingena kwisimo esizinzileyo, ukuchasana okuguquguqukayo kudla ukuzinza.
Ukusuka kwindawo yokujonga idatha yokumelana, utshintsho ukusuka malunga ne-180μΩ ekuqaleni kwe-welding ukuya malunga ne-100μΩ ekugqibeleni inkulu kakhulu.Kwithiyori, i-curve yokumelana ne-dynamic ihambelana kuphela nezinto eziphathekayo, kwaye ineempawu zendalo yonke.Nangona kunjalo, kulawulo lwangempela, kuba ukuchasana kunzima ukukubona, kunzima ukulawula ngokokutshintsha kokumelana.Ukufunyanwa kwe-welding yangoku kulula, ukuba i-curve yokumelana ne-dynamic iguqulwa ibe yi-curve yangoku eguquguqukayo, ikulungele kakhulu ukuphumeza.Nangona igophe langoku eliguquguqukayo linxulumene namandla kunye neempawu zomthwalo we-intermediate frequency spot welder, xa iimeko ze-hardware (i-intermediate frequency spot welder) ziqinisekile, i-curve yangoku eguquguqukayo kunye ne-curve eguquguqukayo yokumelana nemithetho ehambelanayo.
