Cov khoom siv vuam siv feem ntau yog AC thiab DC vuam tshuab, argon arc vuam tshuab, tsis siv vuam tshuab, carbon dioxide shielded vuam tshuab, thiab lwm yam. Cov khoom siv vuam ntau dua kuj suav nrog arc vuam, electroslag vuam, brazing, txhuam vuam, argon arc vuam, Cov pa roj carbon dioxide shielded vuam, thiab lwm yam.
Dab tsi yog cov yam ntxwv ntawm cov khoom siv vuam?
Kuv yuav tsum xyuam xim rau dab tsi thaum siv cov khoom siv vuam?
Cov cuab yeej siv vuam ua haujlwm li cas?
Dab tsi yog cov yam ntxwv ntawm cov khoom siv vuam?
1. Cov khoom siv vuam yuav tsum ruaj khov thiab ruaj khov, nrog cov yam ntxwv ua haujlwm ruaj khov thiab kev ntseeg tau zoo.
2. Ntau yam kev ntsuas cov yam ntxwv ntawm cov khoom siv vuam yuav tsum ua raws li cov kev cai sib xws ntawm cov tshuab kev lag luam kev lag luam tus qauv thiab ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem vuam siv.
3. Cov khoom siv vuam vuam tsis tuaj yeem hloov kho yooj yim thiab intuitively, thiab tuaj yeem ua kom ruaj khov thaum lub sijhawm vuam ntev.
4. Cov khoom siv vuam muaj peev xwm them nyiaj zoo dua rau qhov kev hloov pauv ntawm kev lag luam fais fab.
5. Cov khoom siv vuam yog kev lag luam, siv tau thiab yooj yim los tswj.
6. Raws li kev siv ib txwm siv thiab kev saib xyuas kom zoo, lub neej ua haujlwm ntawm cov khoom siv vuam yuav tsum muaj ntau tshaj 10 xyoo.
Kuv yuav tsum xyuam xim rau dab tsi thaum siv cov khoom siv vuam?
Cov kev xav tau ntawm kev siv cov cuab yeej siv vuam muaj xws li cov khoom siv, cov yam ntxwv ntawm cov qauv, qhov ntev, qhov xav tau precision thiab siv cov qauv ntawm cov qauv yuav tsum tau welded.
Yog tias cov khoom siv vuam yog cov hlau tsis tshua muaj hlau, arc vuam transformer tuaj yeem siv tau; Yog tias cov qauv vuam yuav tsum muaj siab thiab tsis tshua muaj hydrogen electrode vuam, yuav tsum xaiv DC arc vuam tshuab.
Rau tuab thiab loj vuam, electroslag vuam tshuab siv tau; rau bar taub qab vuam, txias siab vuam tshuab thiab kuj taub qab vuam tshuab yuav siv tau. Rau cov khoom siv hlau lossis cov hlau, cov khoom siv hluav taws xob tiv thaiv hluav taws xob thiab corrosion-resistant alloys, inert gas shielded welders, plasma arc welders, electron beam welders, thiab lwm yam tuaj yeem xaiv raws li cov xwm txheej tshwj xeeb.
Rau vuam cov qauv nrog cov qauv ruaj khov thiab qhov ntev ntawm cov khoom loj, cov tshuab vuam tshwj xeeb tuaj yeem siv tau.
Cov cuab yeej siv vuam ua haujlwm li cas?
Lub seam uas txuas ob lub cev sib txuas tsim thaum lub sij hawm vuam ntawm cov khoom siv vuam yog hu ua weld seam. Ob sab ntawm lub vuam yuav raug vuam thaum lub sij hawm vuam, thiab cov qauv thiab cov khoom yuav hloov. Thaj chaw no yog hu ua thaj chaw muaj kev kub ntxhov. Thaum vuam, vim cov khoom sib txawv ntawm cov khoom siv, cov khoom siv vuam, vuam tam sim no, thiab lwm yam, overheating, embrittlement, hardening los yog softening yuav tshwm sim nyob rau hauv lub weld thiab kub cuam tshuam cheeb tsam tom qab vuam, uas kuj txo cov kev ua tau zoo ntawm vuam thiab deteriorates lub weldability. Qhov no yuav tsum tau hloov kho ntawm vuam tej yam kev mob. Preheating ntawm qhov sib txuas ntawm cov vuam ua ntej vuam, kev txuag hluav taws xob thaum vuam thiab tom qab vuam cua sov tuaj yeem txhim kho qhov vuam zoo ntawm cov vuam.
