Kutheni kukho amaqamza kwiindawo zokuwelda kumatshini we-welding we-intermediate frequency spot? Ukubunjwa kwamaqamza kuqala kufuna ukubunjwa kwesiseko seqamza, ekufuneka sihlangabezane neemeko ezimbini: enye yeyokuba intsimbi engamanzi inerhasi eyi-supersaturated, kwaye enye kukuba inamandla afunekayo kwi-nucleation. Uhlalutyo kunye nezisombululo kwingxaki yamaqamza adibeneyo e-solder:
I-supersaturation kwintsimbi engamanzi iphezulu kakhulu, kwaye iphezulu i-supersaturation, iyancipha ngakumbi. Irhasi kunokwenzeka ukuba imvula kwaye yenze amaqamza. Ngoko ke, i-pool etyhidiweyo kwi-welding ineemeko eziyimfuneko ze-supersaturation ukwenza ama-bubbles. Njengenkqubo yekristali yesinyithi, i-nucleation ye-bubble inokwenzeka ngeendlela ezimbini: i-nucleation ezenzekelayo kunye ne-nucleation engabonakaliyo. Ukuba i-bubble core yenziwa, iqamza kufuneka loyise uxinzelelo lolwelo kwaye lenze umsebenzi wokwandisa
Ngenxa yokwanda kwamandla angaphezulu okubangelwa kukwenziwa kwezigaba ezitsha, ukuba undoqo weqamza onobungakanani obubalulekileyo wenziwa kulwelo, kufuneka kunikwe amandla awoneleyo ukwenza amandla enyukliya. Ngokucacileyo, okukhona amandla e-nucleation ephezulu, anqabile ukuba enze i-bubble core. Ngokuchaseneyo, kulula ukwenza i-bubble core.
