Intshayelelo
Kwintsimi ebanzi yokulungiswa kwesinyithi kunye nokuveliswa, okuphakathioomatshini bokuwelda indawo rhoqoziye zaba yimfuneko ngenxa yokusebenza kwazo okugqwesileyo kunye noluhlu olubanzi lwezicelo. Nangona kunjalo, ukuphakamisa ngokupheleleyo izibonelelo zaba matshini, kubalulekile ukuqonda nzulu amanqanaba ahlukeneyo enkqubo yokuwelda. Eli nqaku liphonononga lo mbuzo: "Zingaphi izigaba ezenziwayo kwinkqubo ye-welding ye-mediumumatshini indawo welding frequencyIbandakanya?" kwaye inika ingcaciso eneenkcukacha.
Okuninzi -Uhlalutyo lwenqanaba leNkqubo yeWelding
Inkqubo ye-welding ye-mediumumatshini indawo welding frequencyinokwahlulwa ngokuchanekileyo ngokwala manqanaba angundoqo alandelayo:
Inqanaba 1: Phambi{1}}Inqanaba loxinzelelo
Le yindawo yokuqala yenkqubo ye-welding kunye nesiseko sokuqinisekisa umgangatho we-welding. Ngeli nqanaba, i-electrodes ye-welding yenza uqhagamshelwano oluqinileyo kunye ne-workpiece surface phantsi koxinzelelo olufanelekileyo, yenze indawo yokudibanisa ezinzileyo. Olona sukelo luphambili-loxinzelelo kukuphelisa izithuba phakathi kwemiphezulu yoqhagamshelwano, qinisekisa ukunamathela ngokusondeleyo phakathi kwezinto zokusebenza, kunye nokwaphula iifilimu zeoksidi emphezulu ukunciphisa ukuxhathisa. Phambi{4}uxinzelelo luqinisekisa ukuba i-welding current ihamba kakuhle xa sele inamandla, ibeka isiseko sokufudumeza nokunyibilika okulandelayo.
Inqanaba lesi-2: iNqanaba lokuFuthumala okuMandla
Emva kokuba {0}inqanaba loxinzelelo ligqityiwe, i-electrodes ye-welding inikwa amandla ukutshisa indawo ye-welding. Ngeli nqanaba, i-welding current ivelisa ukushisa okukhulu kwiindawo zoqhagamshelwano, ngokukhawuleza ukuphakamisa izinga lokushisa kunye nokunyibilikisa isinyithi ukwenza i-nugget. Ulawulo oluchanekileyo lweeparamitha ezifana ne-welding current, i-voltage, kunye nexesha kubalulekile ukuqinisekisa iifom ze-nugget ngesantya kunye nobukhulu obufunwayo. Kwakhona kubalulekile ukukhusela ukushisa kunye ne-spatter ukukhusela zombini izixhobo kunye ne-workpiece.
Inqanaba lesi-3: Ukuqulunqa (Ukupholisa iCrystallization) iSigaba
Emva kokuba i-nugget ifikelele kwisimo esifanelekileyo kunye nobukhulu, i-welding current inqunyulwe, kwaye inkqubo ingena kwisigaba sokubumba (i-crystallization epholileyo). Ngeli nqanaba, i-electrodes ye-welding iyaqhubeka ifaka uxinzelelo kwindawo yokudibanisa, ivumela i-nugget ukuba ipholile kwaye ikhanye phantsi kwamandla. Injongo ephambili yokubumba kukuqinisekisa ukuba iibhondi zentsimbi ezicwebezelayo ziqinisiwe, ukuphepha iziphene ezifana ne-shrinkage cavities okanye ii-cracks, ngelixa uphucula amandla kunye nokutywinwa kwe-welded joint. Ulawulo oluchanekileyo loxinzelelo kunye nexesha lubalulekile ukuze kuqinisekiswe uqina olupheleleyo kunye nokwenziwa komgangatho ophezulu{3} we weld.
Ukuqukumbela
Inkqubo ye-welding ye-mediumumatshini indawo welding frequencyluninzi-inqanaba, ngokuchanekileyo{1}}umsebenzi olawulwayo. Ngeempembelelo ze-synergistic zangaphambili{3}uxinzelelo, ukufudumeza amandla, kunye nokubumba, umgangatho kunye nozinzo lwamalungu adityanisiweyo aqinisekisiwe. Kwizicelo ezisebenzayo, iiparamitha ze-welding kunye neenkqubo kufuneka zihlengahlengiswe ngokuguquguqukayo ngokusekelwe kwiimfuno ezithile kunye neempawu ze-workpiece ukuze kuphunyezwe iziphumo ezilungileyo.
Ukongeza, ukugcinwa rhoqo kunye nokhathalelo lwezixhobo kubalulekile ukuqinisekisa ukusebenza okuzinzileyo-kwexesha elide.
