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 yokufudumala ukuthambisa, ukuchasana kuyancipha, ngoko ijika liyancipha 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.
