Welding AN348A flux

Flux - a impahla ngobuningi lwekhemikhali ukuthi isetshenziselwa lula izinqubo yazo zonke izinhlobo zokushisela. Siyabonga kuye, exhunywe weld izinto. Omunye izinhlobo ethandwa kakhulu okokusebenza AN348A yokucucuza.

Kungani kufanele usebenzise le nto?

Flux AN348A (GOST 9078-81) isetshenziswa Welding arc. He biyela the arc futhi weld pool emiphumeleni yizici zemvelo. Ngaphezu kwalokho, ecucuza uyakwazi ukusiza ukucutshungulwa welds Metallurgical.

Lapho Welding (ambozwe) ecucuza ihlanganisa wire. Lokhu kwandisa ukusebenza kahle ezishisayo. AN348A ecucuza isicelo ngesikhathi Welding kagesi, ukuvikela endaweni ukusebenza kusukela emoyeni kanye nezinye amagesi. Lokhu kudala izimo ezidingekile ukusebenza kahle komsebenzi enikezela izinga imfundo weld.

Indlela yokufaka isicelo

Buyisela imishini ephukile izingxenye ngokuvamile ingaba nge Welding. Le ndlela ikuvumela ukuba imali kanye nesikhathi. Inqubo ngeke kuthathe isikhathi. Siyabonga kuye, akudingekile ukuba ulinde isikhathi eside ngoba izingxenye ezisele, okumele "ngokushesha" ukuza.

Phakathi Welding AN348A ecucuza kanye wire ezidla ndawonye zibe zone arcing. Kube kwenzeka ukuncibilika metal isizinda imiphetho, izintambo futhi yokucucuza. Ngenxa yalokho, i-bubble emhlabeni arc livela, ehlanganisa igesi zensimbi izinto yokucucuza. Yokuhamba yokucucuza arc ncibilika antante phezulu wechibi weld. Lokhu yakha slag. Lokhu kwenzelwa ukuvikela ebusweni kusukela emoyeni, okuyinto ayidingeki. Ukushisela ubushelelezi eliphezulu. Ngemva epholisa ikhekhe slag isuswe kalula.

Ngaphandle izakhiwo ngenhla echazwe, ongavikela yokucucuza UWelder asebenza ezintweni ezivela amagesi ayingozi nothuli.

AN348A Flux: Ukucaciswa

Lokhu kwaziswa kuyinto brown okusanhlamvu amnyama. usayizi yabo imayelana 0.35-0.5 ml. Grain e isakhiwo zabo zifane izingcezu ingilazi. ngobuningi yabo ukuminyana ungaphakathi uhla 1.3-1.8 kg / DM ^3. Uma usebenzisa izinto kufanele abe sesimweni ezomile. Uma kungenjalo, khona-ke kuyoba ezomile njalo. Ngenxa yale njongo, it is omisiwe ihora at + 300-400 ⁰ C.

Omunye izici ezibaluleke kakhulu fluxes kuyinto reactivity yabo. Ngo AN348A lesi silinganiso ungaphakathi uhla 0.7-0.75 Af. Lokhu kusho ukuthi AN348A ecucuza iphathelene isigaba kakhulu asebenzayo. Phakathi nenqubo Welding usebenzisa izinto radiative ovelele ekushayweni, ukubaluleka okuhambelana omisiwe kwezinkambiso amazinga (hhayi ningi than 18 Mr / hr).

Ukwakheka ecucuza kuhlanganisa Silicon oxides (kufika ku-44% wabantu ivolumu isamba impahla), manganese (kufika ku-38%), i-calcium (kufika ku-12%), i-magnesium (kufika ku-7%), i-aluminiyamu (kufika ku-13%) nensimbi (kufika ku-2.2 %). Ngaphezu kwalokho, kukhona sulphur ne phosphorus. Futhi iqukethe izinhlayiya angaphandle okusalayo asendabeni ngesikhathi senqubo yokukhiqiza (ezifana amalahle izinsalela, coke, graphite, metal chips, njll).

AN348A ecucuza ingasetshenziswa ezimweni ezahlukene kanye anhlobonhlobo okushisa kuma. It is hhayi Kunconywa ukuba sisisebenzise North kwamazinga okushisa aphansi kakhulu (ngezansi -30 ⁰ C).
