Cov pa roj carbon hlau siab vuam yog tus luag kom tawg. Cov khoom siv dab tsi tuaj yeem daws qhov teeb meem no?

Nyob rau hauv cov teb ntawm cov neeg kho tshuab tsim, pwm ua, thiab tshuab hluav taws xob siv tau los ua cov cuab yeej tseem ceeb xws li cov cuab yeej roj carbon monoxide (nrog rau cov cuab yeej roj carbon monoxide (nrog rau cov cuab yeej roj carbon monoxide (nrog rau cov cuab yeej roj carbon monoxide (nrog rau cov cuab yeej roj carbon monoxide) xws li cov cuab yeej muaj roj ntsha Txawm li cas los xij, vuam ntau-carbon hlau ib txwm muaj kev sib tw kev lag luam, raws li nws tsis tshua muaj kev cuam tshuam rau lub neej ua haujlwm tab sis kuj yuav ua rau muaj kev nyab xeeb. Kab lus no yuav tshuaj xyuas cov laj thawj tseem ceeb rau cov khoom xaiv uas muaj cov kws xaiv vuam, thiab muab cov khoom xaiv xaiv vuam los pab cov neeg siv hluav taws xob sib tsoo los ntawm cov khoom siv hlau hluav taws xob.

I. Xaiv cov cuab yeej txoj hauv kev yog qhov tseem ceeb, thiab peb hom vuam tshuab yog haum rau cov roj carbon steel vuam

1. Pulsed Tig Vuam Tshuab: Tsim rau precision vuam ntawm nyias-walled high-carbon steel
• Lub pulsed Tig vuam tshuab twb ua tiav 'kev tswj hwm ntawm tshav kub kub ' los ntawm cov mem tes ua kom muaj kev tawm tshiab. Lub ncov tam sim no ntawm cov mem tes yog siv los melt cov hlau los ua lub pas dej muaj qhov ruaj khov, thaum pib txo qhov loj me ntawm cov cua sov-cuam tshuam nrog kev sib cav sib ceg. Nws tau txais txiaj ntsig zoo nyob rau hauv lub ntsej muag weld zoo nkauj weld thiab tsis muaj lub ntsej muag. Nws yog qhov tsim nyog rau nyias-walled high-carbon steel seem nrog ib thickness ntawm tsawg dua 3 hli (xws li precision pwm ntxig thiab tej cuab yeej me me). Ntxiv mus, Argon Uldle tuaj yeem txo cov hydrogen ingress thiab txo qis kev pheej hmoo ntawm hydrogen-inducts cracking.
• Txawm li cas los xij, kev sib tw vuam ntawm pulsed Tig vuam tshuab yog tus nqi qis. Lawv xav tau kev siv cov hlau pub thiab muaj cov kev xav tau siab rau cov neeg ua haujlwm, ua rau lawv tsis haum rau cov loj-pob tuab vuam.
2. Low-hydrogen txhais tes arc vuam tshuab (nrog preheating muaj nuj nqi): haum rau cov pa hluav taws xob ntawm cov paib nruab nrab-thickness
• Lub tshuab hluav taws xob qis-hydrogen ar welး welding, siv ua ke nrog cov tshuab hluav taws xob, ua rau muaj kev pheej hmoo ntawm hydrogen-inducts cracking ntawm qhov chaw. Qee qhov qauv siab kawg tau nruab nrog kev ua haujlwm preheating uas tuaj yeem ua kom preheat qhov kev ua haujlwm txias, thiab tso qee qhov kev ntxhov siab thermal. Hom welding no muaj qhov ua haujlwm tau ua hauj lwm qis thiab haum rau nruab nrab-tuab cov pa roj carbon hlau nrog lub zog ntawm 5-20 mm (xws li cov zog ntawm 5,20 mm (cov khoom siv. Ntxiv mus, cov cuab yeej siv tau yog ib nrab, muab txiaj ntsig zoo rau nyiaj.
3. Roj Hlau Arc Vuam Tshuab (Mig / Mag, Nrog Dual-Kev Muaj Peev Xwm Dual): Haum rau Loj-Batch Think Think
• Mig / Mag Vuam tshuab nrog DUAL-PEM TES muaj ua haujlwm hloov chaw los ntawm kev siv cua sov ntau dhau los thiab nce vuam siv nrawm kom tau raws li qhov kev xav tau ntawm cov kev xav tau loj. Thaum lub sij hawm vuam, muaj cov roj sib xyaw ua ke, uas muaj kev tiv thaiv zoo dua li cov neeg muaj ntxhiab tsw qab argon thiab tuaj yeem txo cov roj av hydrogen. Qee cov qauv kuj tseem muaj ib qho 'ntxhov siab nyem ' kev pab cuam uas pab tso cov kev ntxhov siab vuam los ntawm kev kho cov nthwv dej tam sim no.
• Hom vuam welding no yog haum rau tuab high-carbon steel seem nrog ib thickness ntawm ntau tshaj 8 mm (cov kab ke-cov kab ntawv thiab lub iav loj loj). Txawm li cas los xij, cov cuab yeej siv tau yog qhov tseem ceeb, thiab nws yuav tsum tau siv ua ke nrog tshwj xeeb ntawm cov xaim hluav taws xob vuam.

Ii. Cov cuab yeej xaiv yuav tsum yog raws cov xwm txheej, thiab cov txheej txheem yuav tsum tau ua ke rau kev tiv thaiv txuas ntxiv tawg

• Rau me-batch precision nyias-walled seem, lub pulsed kiv vuam tshuab yog thawj qhov kev xaiv. Nws yuav tsum tau siv nrog kev tiv thaiv kev sib cav thiab tom qab weld tsawg-ntsuas kub npau taws rau kev tshem tawm kev ntxhov siab ntxiv.
• Rau nruab nrab thiab me me batch nruab nrab-tuab qhov chaw, lub qis-hydrogen txhais tes arc vuam tshuab muab tus nqi zoo dua rau nyiaj. Nws yuav tsum tau ua ke nrog cov txheej txheem xws li electrode ziab, workpiece preheating (kom tuab weld cua txias (npog nrog Asbestos daim ntaub).
• Rau loj-batch tuab phaj, lub dual-multion mig / Mag Vuam tshuab yog qhov haum ntau. Nws tuaj yeem siv nrog cov hlau pub tsis siv neeg thiab tom qab Weld dehydrogenation kev kho mob txhawm rau txhim kho kev ua tau zoo thiab zoo.

Yog tias koj muaj vuam tshuab yuav tsum tau, thov hu rau Ms. Zhao
