Yintoni iNqanaba lokuFundisa laMandla leNdawo yokuWelder ePhakathi?

I-Medium frequency spot welding yindlela esetyenziswa ngokubanzi kumashishini okuvelisa ukudibanisa iintsimbi kunye. Inqanaba elinye elibalulekileyo ekusebenzeni kwe-medium frequency spot welder sisigaba sokufudumeza samandla. Kule nqanaba, izixhobo ze-welding zihambisa umthamo olawulwayo wamandla ombane kwiindawo zokusebenza, ukudala indawo yendawo yokushisa okukhulu kwiindawo zoqhagamshelwano.

Ngexesha lesigaba sokufudumeza samandla, i-medium frequency spot welder isebenzisa i-alternating current (AC) enezandi ezisuka kwi-1000 ukuya kwi-10000 Hz. Le frequency ephakathi i-AC ikhethwa ngenxa yokuba ibetha ibhalansi phakathi kwe-high-frequency kunye ne-low-frequency alternatives. Ivumela ukuhanjiswa kwamandla okusebenzayo kunye nokulawula ngokuchanekileyo inkqubo yokufudumala.

Isigaba sokufudumeza samandla sisebenza kwiinjongo ezininzi ezibalulekileyo kwinkqubo ye-welding. Okokuqala, ifudumeza iindawo zetsimbi, ukunciphisa ukutshatyalaliswa kwe-thermal xa i-welding yangoku isetyenziswa. Oku kufudumeza ngokuthe ngcembe kunciphisa ukuphazamiseka kwezinto kwaye kunceda ukugcina ingqibelelo yesakhiwo somdibaniso odibeneyo.

Okwesibini, ukufudumeza kwendawo kuthambisa iindawo zetsimbi, ukukhuthaza ukuhanjiswa kombane okungcono phakathi kwezinto zokusebenza. Oku kubalulekile ekufezekiseni i-weld engaguqukiyo nethembekileyo. Isinyithi esithambileyo sikwanceda ukususa izinto ezingcolisa umphezulu ezifana neeoksidi, ukuqinisekisa i-welding interface ecocekileyo.

Ngaphezu koko, isigaba sokufudumeza amandla sidlala indima ekufezekiseni ukuguqulwa kwe-metallurgical. Njengoko isinyithi sitshisa, i-microstructure yayo iyatshintsha, ikhokelela ekuphuculeni amandla e-weld kunye nokuqina. Esi sigaba esilawulwayo siqinisekisa ukuba izinto eziphathekayo ziyaphuculwa, kunokuba ziphazamiseke.

Ubude besigaba sokufudumeza amandla buyahluka ngokusekelwe kwizinto ezifana nodidi lwentsimbi oludityanisiweyo, ubukhulu bayo, kunye neeparitha ezifunwayo ze-welding. Oomatshini bokuwelda bamabala aphakathi banamhlanje baxhotyiswe ngeenkqubo zolawulo eziphucukileyo ezilungelelanisa ixesha lokufudumeza kunye negalelo lamandla ngokweemfuno ezithile zomsebenzi wokuwelda ngamnye.

Ukuqukumbela, inqanaba lokufudumeza amandla kwi-medium frequency spot welder linyathelo elibalulekileyo kwinkqubo ye-welding. I-preheats i-workpieces, iphucula ukuhanjiswa kombane, icoca iindawo ezingaphezulu, kwaye igalelo ekuphuculeni i-metallurgical. Esi sigaba sibonisa ukuchaneka kunye nokuguquguquka kweendlela zokuvelisa zanamhlanje, ukuqinisekisa i-welds eqinile kwaye ethembekileyo yoluhlu olubanzi lwezicelo.
