MIG welding - ngokukhawuleza nangendlela efanelekileyo

Welding - kodwa inkqubo nanto uvumela kakhulu ngokuthembekileyo ngokuchanileyo ukwenza uqhagamshelwano isigxina iindawo okanye iinxalenye amanqaku ezenziwe ngeentlobo ezahlukeneyo zesinyithi. Ukuza kuthi ga ngoku, buphuhliswe buqaliswe buphenjelelwa ukuvelisa iindlela ezininzi ezahlukeneyo kunye nobuchule ukuwelda nokumanyana. Nganye kwezi ndlela zinezibonelelo nezingalunganga.

Enye ubuchwepheshe welding edume yi welding semi-ngokunokwayo ezahlukeneyo umoya igesi olukhuselayo. Oku uyakwazi ukwenza nkqu iingcali kunye emfundo asezantsi kunokuba ezifunekayo manual arc welding. Kulo mzekelo, inkqubo kuthatha ixesha ngaphantsi. Oku kubangela weld technology lwezifundo ekumgangatho ophezulu kwaye ayifuni zabo elandelayo ukusuka zeBlack. uqhubekeko phambili (primer, ipeyinti, njl) welding, iimveliso zingenziwa ngaphandle kokulibazisa. Ukusetyenziswa semi-oluzenzekelayo fusion welding ikuvumela izihlanganisi piece zesinyithi ezicekethekileyo kakhulu (0.1 - 1.5 mm), enze ingenamthungo ukudibanisa kunye beentanda wegophe, amalungu aphathe kangangoko encinane. Yeyona inkqubo iwelding ifanelekileyo ukuze amancinci okanye imveliso mass.

Igama "okuzenzelekayo" Lo bugcisa ingakumbi wire. Enyanisweni, yiloo arc efanayo ukuwelda ucingo electrode eyodwa oluqhutywa igesi egalelwe. Umgaqo kuyo esekelwe iwelding semi-automatic, ilula. lokondla feeder segesi ucingo kuveliswe kwisixhobo eso siwamkelayo umyalezo, uze - kwindawo weld. ezizodwa isixhobo ulawulo izixhobo yenzelwe ukulawula isantya wire electrode.

Ukuqala umzimba ukusebenza iquka izitshixo ngaxeshanye apho unikezelo irhasi kunye wire. Phambi kokuba ekuqaleni kwenkqubo isithuba ekujongwe weld ingenamthungo izaliswe yokumpompoza indlu okhethekileyo. Excitation lwenziwa pewa sliding phambili i electrode ecaleni iikona Imiphezulu welding xa inowuthi electrode ibandakanyiwe, okanye xa sele idityaniswe feed ligazi ukumpompoza kuhluthiswa. Kamva ke ndinkqonkqoza electrode tip eqina SLAG, ukuba arc kuhluthe kwaye kwakhona ephakamayo. Le nkqubo ngokuqhelekileyo luqhutywa nge alternating current, nangona kusenokwenzeka ukuba usebenzise ngokusisigxina.

MIG welding - inkqubo ngokuyinxenye ezenzekelayo. Ukuhambisa umnini ecaleni zentsimbi ingenamthungo senziwe ngesandla, nayiphi ubunzima ekuye kwagxininiswa kwi ngesebe lenkawu esisodwa kubekwa phezu kwimveliso. Zisetyenziswa ngogesi eziphathekayo nezinto zokubhala, ukhetho kuxhomekeka kumsebenzi iwelding ethile. I electrode zikhethwa ngokungqinelana iimpawu intsimbi welding, kwaye iimpawu weld ukuba ifunyenwe. Gesi uvikele, apho welding yenziwa semi wakhetha ngokusekelwe ngeempawu ngentsimbi welding. Kuba low steel carbon uvikele igesi kudala ikharbon dayokhsayidi (CO _2), argon kanga. Negesi inikezelwa ukusuka umlomo, kancinane umoya ukusuka kwindawo ukuwelda kunye nokukhusela umthungo.

Ngokuthenga izixhobo welding, abathengi abaninzi bafuna ukuba nako ukuvelisa kwakhona ukuwelda aluminiyam. Ngenxa yobume intsimbi, welding semi-oluzenzekelayo aluminiyam yobuchwepheshe nzima ngaphezu ambaxa iimveliso ngentsimbi. Ubunzima ezinxulumene umahluko omkhulu lobushushu ukunyibilika aluminiyam (660 ° C) kunye zokhuseleko umboniso kumphezulu wayo (2200 ° C). Fumana umthondo umgangatho weld kunye elungileyo semi-oluzenzekelayo kwindawo argon kunokwenzeka, kodwa apha zonke ziya kuxhomekeka izakhono, nangobungcibi kunye nobuchule le kopi ukwenza lo msebenzi.
