Sefahleho se thata Manual electrode weld fabrication stuff
GEH-547 ke electrode ea letsoho bakeng sa valve ea tšepe e holim'a tšepe tlas'a maemo a Chinese GB/T984 EDCrNi-A-15.E sebelisoa haholo-holo bakeng sa li-valve le likarolo tse ling tsa ho tiisa tsa lisebelisoa tse phahameng tsa boiler liteisheneng tsa motlakase tlas'a 570 ℃.Surfacing welding ke tjheseletsa e khethehileng alloy holim'a karolo efe kapa efe ea workpiece, morero oa eona ke ho ntlafatsa ho hanyetsa kutu, ho hanyetsa kutu le ho hanyetsa mocheso oa sebaka se sebetsang, e le ho fokotsa litšenyehelo, ho ntlafatsa ts'ebetso e pharaletseng le bophelo ba tšebeletso. ts'ebetso ena ea eleketrode bakeng sa eleketrode e thibelang ho roala holim'a metsi, e tsejoang hape e le "electrode" e holimo.
Kopo & Maemo
GEH-547 elektrode ea letsoho e sa khoneng ho roala sefahleho se thata e sebelisoa haholo ho phahamisa le ho lokisa likarolo tse tsofetseng tsa lisebelisoa tsa lik'hemik'hale le lisebelisoa tse fapaneng tsa mochini.Joalo ka likarolo tse tlokotsing tsa slag crusher (joalo ka hamore ea crusher, hamore plate, counter plate), sesebelisoa sa ho laolla samente (tray, spire, grate), mochini oa ho lokisa litene, li-mixer blades, li-blades tsa mochini o phunyang, likhaba tsa fene ea semela sa motlakase, ho phatloha ha leloala la tšepe. sebopi chute lesela poleiti, rolara, khoune robehileng, mochine oa mashala joalo-joalo.Phello e holimo e bolela ho thatafala, ho hanyetsa le ho hanyetsa mocheso oa lera la welding, 'me tshebetso ea eona e amana le lintlha tse latelang:
1. Boholo ba hona joale ba welding, bolelele ba arc.E kholo ea hona joale, arc e telele, lisebelisoa tsa alloying tse bonolo ho chesa, ho seng joalo, phetoho ea likarolo tse ntle tsa alloying.2. Mocheso oa preheating le maemo a pholileng a liehang a khetholla boleng ba lera le holimo.3. Mekhoa e fapaneng ea phekolo ea mocheso e ka sebelisoa ho fumana boima bo fapaneng ba litšepe tse ling tse holim'a metsi.
Likaroloana
GEH-547 ke mofuta o tlase oa sodium hydrogen mofuta oa chromium-nickel butt welding electrode, opereishene e ntle, ho phatloha ho fokolang, ho bonolo ho slag, sebopeho se setle, ho bonolo ho etsa ts'ebetso ea mochini;Ho matlafatsoa ha silicon ho matlafatsa ho thatafala, ho hanyetsa ha abrasion, ho hanyetsa kutu le khanyetso ea oxidation ea tšepe e holim'a metsi.Bothata bo atileng haholo bo hlahang holim'a metsi ke ho petsoha.Mekhoa e ka sehloohong ea ho thibela ho phunyeha ke e latelang: 1. Preheat pele ho welding, laola mocheso pakeng tsa lihlopha, ho lieha ho pholile ka mor'a ho cheselletsa;2. 2. Kalafo ea mocheso ho felisa khatello ea kelello ka mor'a tjheseletsa.3, qoba ho phatloha ho nang le mekhahlelo e mengata, u sebelisa elektrode e holimo ea mofuta oa haedrojene.4. Pele ho welding, e hloka ho omisoa ka 300-350 ℃ bakeng sa hora e le 'ngoe;Ho hlokahala ho tlosa lintho tse bonahalang motheo holim'a mongobo, mafome litsila tse teng, oli, joalo-joalo Hape lokela ho ela hloko tsela ea arc le arc.
