Copper Welding yog qhov nyuaj, Lub Tshuab Vuam Tshuab tuaj yeem tuav nws? Koj puas xav tau cov txuj ci tshwj xeeb?

I. Cov tshuab vuam ib txwm yog qhov nyuaj los tuav txoj haujlwm, thiab lawv qhov tsis zoo yog qhov pom tseeb

1. Ordinary Manual Arc Vuam Tshuab: Yuav luag tsis muaj txiaj ntsig
• Hom vuam tshuab no tso siab rau cov cua sov uas tsim los ntawm qhov kub ntawm qhov vuam pas nrig. Lub tshav kub input tsis txaus rau yaj los ntawm cov khoom siv tooj liab. Ntxiv mus, yuav luag tsis muaj vuam rods tshwj xeeb tsim rau cov ntaub ntawv tooj liab nyob rau hauv kev ua lag luam. Yog hais tias koj yuam siv lwm yam vuam rods, lub resulting weld seam yuav tsis muaj kev ruaj ntseg los yog tag nrho ntawm slag. Nws tsuas yog siv tau los kho lub qhov me me ib ntus. Rau qhov zoo tooj liab vuam, nws yog kiag li unreliable.
2. Basic DC TIG Vuam Tshuab: txwv rau nyias ntshiab tooj liab
• Qhov yooj yim DC TIG vuam tshuab tuaj yeem tsis tshua muaj vuam nyias-walled ntshiab tooj liab nrog lub thickness ntawm 1-3 hli, xws li me me tooj liab davhlau ya nyob twg connectors. Txawm li cas los xij, muaj ntau yam teeb meem: nws tsis muaj cathode tu muaj nuj nqi, uas txhais tau hais tias nws tsis tuaj yeem tshem tawm cov oxide zaj duab xis ntawm cov khoom siv tooj liab, ua rau nws yooj yim rau slag rau hauv qhov vuam seam. Lub tshav kub input tswj tsis meej. Thaum welding cov ntaub ntawv tuab dua, nws yuav 'dhau.' Nws kuj tsis tuaj yeem welded tooj dag (lub zinc hauv tooj dag yooj yim evaporates ntawm qhov kub siab, ua rau lub vuam seam ua nkig).
3. Ordinary MIG Vuam Tshuab: Yooj yim rau Burnthrough thiab lwm yam teeb meem
• Thaum vuam cov ntaub ntawv tooj liab nrog lub tshuab MIG zoo tib yam, yuav tsum muaj tam sim no loj los yaj cov ntaub ntawv tooj liab. Txawm li cas los xij, lub siab tam sim no tuaj yeem hlawv tau yooj yim los ntawm cov khoom siv tooj liab nyias. Tsis tas li ntawd, siv cov roj ntshiab argon rau kev tiv thaiv tsis zoo hauv inhibiting oxidation thiab gas absorption ntawm cov ntaub ntawv tooj liab. Thaum welding tooj dag, evaporation ntawm zinc yog hnyav heev. Qhov no tsis yog tsuas yog ua phem rau ib puag ncig xwb tab sis kuj txo lub zog ntawm vuam seam, ua tsis tau raws li qhov yuav tsum tau ua.

Hauv cov ntsiab lus, cov tshuab vuam zoo tib yam tuaj yeem tsuas yog siv me me ntawm qhov xav tau qis-walled ntshiab tooj liab vuam. Yuav kom vuam cov ntaub ntawv nruab nrab-tuab tooj liab, tooj dag, lossis tooj liab qhov chaw nrog lub zog thiab hluav taws xob conductivity, cov khoom siv xws li cov tshuab vuam tshuab, laser vuam tshuab, thiab cov tshuab laser vuam tshuab, nrog rau cov txheej txheem tshwj xeeb, yog qhov tsim nyog.

II. Cov cuab yeej tshaj lij yog qhov tsim nyog, thiab qhov kev xaiv yog nyob ntawm qhov xwm txheej

1. Spot Welding Tshuab: Thawj Kev Xaiv rau Batch Spot Vuam ntawm nyias-walled tooj liab cov ntaub ntawv
• Lub tooj liab qhov chaw vuam tshuab tso siab rau lub siab ntawm electrodes thiab siv kev sib cuag tiv thaiv kom sov thiab yaj cov ntaub ntawv tooj liab hauv zos los tsim cov ntsiab lus vuam. Nws qhov zoo dua yog ceev; txhua qhov weld point tsuas yog siv 0.1-1 vib nas this. Nws yog tshwj xeeb tshaj yog haum rau batch welding ntawm nyias-walled tooj liab cov ntaub ntawv (0.1-2 hli), xws li kev twb kev txuas ntawm tooj liab leads nyob rau hauv cov khoom siv hluav taws xob thiab kev sib dhos ntawm cov tooj liab me me.
• Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias koj yuav tsum xaiv lub tshuab tooj liab tshwj xeeb vuam tshuab. Vim tooj liab muaj hluav taws xob conductivity siab, nws yuav tsum tau welding tsis muaj siab tam sim no thiab lub sij hawm luv luv kom tsis txhob welding cuav. Cov electrodes kuj xav tau kev saib xyuas tsis tu ncua los tiv thaiv oxidation thiab hnav los ntawm kev cuam tshuam vuam zoo.
2. Laser Vuam Tshuab: Qhov tseem ceeb rau High-Precision Copper Vuam
• Lub tshuab laser vuam siv lub tshuab hluav taws xob muaj zog laser los yaj cov khoom siv tooj liab. Lub tshav kub cuam tshuam yog qhov me me, thiab nws tuaj yeem tswj tau qhov vuam seam. Lub resulting weld seam yog du thiab yuav luag tsis xav tau tom qab ua tiav. Nws muaj ntau yam kev hloov pauv thiab tuaj yeem txuas cov tooj liab thiab tooj dag nrog cov tuab ntawm 0.05 txog 6 hli. Nws yog qhov tsim nyog rau cov xwm txheej uas muaj qhov tseeb thiab qhov yuav tsum tau ua, xws li cov khoom siv tooj liab hauv cov khoom siv hluav taws xob precision thiab tooj liab txuas hauv cov khoom siv kho mob.
• Thaum vuam cov ntaub ntawv tooj liab, nws raug nquahu kom xaiv lub tshuab laser vuam nrog cov mem tes ua haujlwm, uas tuaj yeem txo cov cua sov thiab tsis txhob deformation ntawm cov khoom tooj liab. Nyob rau tib lub sijhawm, nws yuav tsum tau siv nrog kev tiv thaiv roj argon los tiv thaiv oxidation thiab roj nqus, kom ntseeg tau qhov zoo ntawm cov vuam seam.
3. Robotic Laser Vuam Tshuab: Qhov Kev Xaiv Rau Loj-Batch Standardized Copper Vuam
• Cov neeg hlau laser vuam tshuab yog kev sib txuas ntawm lub tshuab laser vuam thiab lub caj npab neeg hlau, uas tuaj yeem ua tiav vuam vuam thiab tuaj yeem ua haujlwm tsis tu ncua rau 24 teev. Nws qhov vuam precision yog ruaj khov thiab yuav tsis cuam tshuam los ntawm tib neeg kev ua haujlwm sib txawv. Nws yog tsim rau loj-batch tooj liab welding, xws li vuam ntawm tooj liab hlau harnesses nyob rau hauv kev lag luam automotive thiab batch vuam ntawm tooj liab terminals nyob rau hauv cov khoom siv fais fab.
• Nws muaj qhov zoo sib xws ntawm kev hloov pauv mus rau laser vuam tshuab nyob rau hauv cov nqe lus ntawm cov khoom siv tooj liab tuab thiab tuaj yeem tswj cov kev sib tw vuam, xws li cov voj voog ncig ntawm qhov tsis sib xws ntawm tooj liab. Nws yog tshwj xeeb tshaj yog haum rau cov lag luam nrog cov khoom loj, uas tuaj yeem txhim kho kev ua haujlwm zoo thiab txo cov nqi zog.

III. Cov txheej txheem tshwj xeeb yog xav tau rau kev siv tooj liab, thiab peb kauj ruam kom ua tau zoo

1. Ua ntej Vuam: Kev tu kom huv yog qhov tseem ceeb
• Cov roj thiab oxide zaj duab xis nyob rau saum npoo ntawm cov khoom siv tooj liab yog qhov muaj peev xwm vuam phom sij thiab yuav tsum tau ntxuav kom huv si. Siv acetone los yog cawv kom tshem tawm cov roj, cov ntawv xuab zeb rau polish los yog sulfuric acid kom tshem tawm cov oxide zaj duab xis los ntawm cov tooj liab ntshiab, thiab cov tshuaj ntxuav tshwj xeeb los kho cov tooj dag. Yog tias vuam tuab cov ntaub ntawv tooj liab (ntau tshaj 8 hli), preheat rau 200-400 ° C ua ntej vuam kom txo qis cua sov thiab zam tsis tiav vuam.
2. Thaum lub sij hawm Vuam: Parameters thiab kev tiv thaiv yuav tsum nyob rau hauv qhov chaw
• Kho qhov tsis haum raws li cov khoom siv thiab hom khoom siv tooj liab. Piv txwv li, thaum siv lub tshuab laser vuam rau vuam 3 hli ntshiab tooj liab, lub zog ceev yuav tsum tau kho kom haum rau ntau yam. Kev tiv thaiv roj kuj tseem ceeb. Siv cov khoom sib xyaw ntawm argon thiab helium rau kev siv tooj liab ntshiab, thiab sib xyaw ntawm argon thiab 5% -10% nitrogen rau tooj dag vuam, nrog tus nqi ntws tswj ntawm 20-25 L / min los tiv thaiv oxidation thiab gas nqus.
3. Tom qab Vuam: Kev txias qeeb thiab kev tshuaj xyuas yog qhov tseem ceeb
• Tom qab welding, npog lub weld seam nrog asbestos daim ntaub kom cia cov khoom siv tooj liab kom txias maj mam, txo cov kev ntxhov siab sab hauv thiab tsis txhob deformation thiab tawg. Rau cov tooj liab tuab, qhov kub thiab txias (250-300 ° C rau 1 teev) tuaj yeem tshem tawm kev ntxhov siab ntxiv. Thaum kawg, tshuaj xyuas cov vuam seam los xyuas qhov porosity, tawg, thiab ua cov kev ntsuam xyuas hluav taws xob raws li qhov xav tau los xyuas kom meej qhov zoo raws li cov qauv.
