3.2mm carbon steel welding electrode aws e7018 alloy steel electrode
Ho hlahisa electrode ea welding aws e7018 - tharollo ea mantlha ea litlhoko tsohle tsa hau tsa welding.Hore na o sebetsa morerong o moholo oa kaho kapa o sebetsana le mesebetsi e menyenyane ea ho tjheseletsa, o hloka electrode e tšepahalang le ea boleng bo holimo e fanang ka liphetho tse ikhethang.The aws e7018 ke sehlahisoa se joalo seo u ka se tšepang le ho itšetleha ka sona.
Sena se tjheseletsa eleketrode aws e7018 ke eleketrode tsohle-morero e loketseng ho tjheseletsa ka thepa e sa tšoaneng.Lisebelisoa tsena li kenyelletsa tšepe e bonolo, tšepe e tlaase ea alloy le tšepe e phahameng, e leng se etsang hore e be electrode e nang le mefuta e mengata bakeng sa merero ea li-welding tsa mefuta eohle.Li-aws e7018 li na le lintho tse fokolang tsa haedrojene, tse ntlafatsang ts'ebetso ea eona le ho tšoarella, ho etsa bonnete ba hore manonyeletso a hau a ho tjheseletsa a lula a le matla a bile a sireletsehile.
Ntle le litaba tsa eona tse tlase tsa hydrogen, li-electrode tsa aws e7018 le tsona li bonolo ho li sebelisa ka lebaka la litšobotsi tsa eona tse tsitsitseng tsa arc.Karolo ena e bohlokoa haholo ha o cheselletsa motlakase o nang le mohloli oa matla a sa feleng.Ho tsitsa ha arc ho u thusa ho fumana weld e boreleli, esita le e se nang spatter, e etsang hore ho hloekisoe kapele le ho se na mathata.
The welding electrode aws e7018 e boetse e sebetsa hantle haholo, ka sekhahla se phahameng sa deposition se u lumellang hore u phethe merero ea hau ea ho cheselletsa ka nako.Ts'ebetso ena e hlahelletseng e bakoa ke lisebelisoa tse ntle tsa ho kolobisa le ho qala li-arc, tse etsang hore ho be bonolo ho uena ho qala welding hang-hang.Ts'ebetso ena e ntseng e eketseha e bolela hore o ka boloka nako, chelete le ho fokotsa litšenyehelo tse akaretsang tsa tjheseletsa.
E etselitsoe ho finyella litekanyetso tsa indasteri, electrode ea welding aws e7018 e fana ka ts'ebetso e tsitsitseng le e ka tšeptjoang e finyellang kapa e fetang litebello.E boetse e behiloe tekong e matla ho netefatsa hore e khona ho mamella khatello ea maikutlo le maemo a feteletseng.Ho tšepahala hona ho etsa hore e be khetho e nepahetseng bakeng sa mesebetsi ea li-welding masimong a boima joalo ka liindasteri tsa kaho le tsa boenjiniere.
Qetellong, haeba u le 'marakeng bakeng sa electrode ea boleng bo phahameng ea welding e kopanyang ho tšepahala, ho feto-fetoha ha maemo, le ts'ebetso e phahameng, joale motlakase oa welding aws e7018 ke khetho e ntle ka ho fetisisa.Electrode ena e loketse merero e mengata ea li-welding, ho tloha ho litokiso tse bonolo ho ea ho merero e rarahaneng ea kaho kapa ea boenjiniere.Tsetela ho li-welding electrode aws e7018 kajeno 'me u rue molemo ts'ebetsong le boleng bo ke keng ba lekanngoa.
