Resistance Welding Vs Arc Vuam: Vim li cas Qhov Kev Tiv Thaiv Vuam Zoo Tshaj Rau Nyias Phaj Vuam?

Hauv kev lag luam welding, tsis kam vuam thiab arc vuam yog ob txoj kev vuam. Thaum peb tsom mus rau nyias phaj welding, kuj welding feem ntau nyiam dua. Vim li cas qhov no?

Cia wb mus saib qhov ua haujlwm vuam ua ntej. Nws lub hauv paus ntsiab lus yog siv cov hluav taws xob tiv thaiv hluav taws xob los ntawm qhov tam sim no dhau los ntawm kev siv vuam thiab kev sib cuag kom yaj cov hlau, yog li ua tiav vuam. Cov txheej txheem vuam yog nrawm thiab feem ntau tuaj yeem ua tiav hauv ib qho tam sim, ib yam li muab cov hlau 'flash weld', qhov twg cov cua sov yog concentrated ntawm qhov chaw vuam thiab cov khoom nyob ib puag ncig tsis tshua muaj kev cuam tshuam los ntawm tshav kub. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov phaj nyias nyias vim tias cov phaj nyias nyias yog qhov muag heev thiab tsis tuaj yeem tiv taus ntev los yog kub dhau, txwv tsis pub lawv yuav ua rau deformation thiab hlawv. Kev tiv thaiv vuam tuaj yeem tswj hwm lub zog, ib yam li siv lub ntsej muag 'thermal scissor' los siv cov cua sov kom meej ntawm qhov chaw vuam, tiv thaiv cov duab thiab kev ua haujlwm ntawm cov phaj nyias.

Tsis tas li ntawd, kev siv vuam vuam yog qhov yooj yim rau kev khiav lag luam, thiab feem ntau tsis tas yuav tsum tau ntxiv cov ntaub ntawv muab tub lim xws li vuam hlau, txo kev siv thiab nqi ntawm cov khoom siv ntxiv. Cov tsos ntawm cov welded sib koom tom qab vuam kuj yog tus du thiab zoo nkauj, nrog tsawg dua cov kauj ruam tom ntej. Piv txwv li, hauv kev tsim tsheb, ntau cov phaj nyias nyias xws li lub qhov rooj ntawm lub tsheb thiab lub cav hoods tau txuas nrog cov vuam tsis kam. Cov welded qhov chaw tsis yog tsuas yog ruaj khov thiab txaus nyiam, tab sis kuj txhim kho kev tsim khoom.

Cia wb mus saib lwm qhov arc vuam. Nws tsuas yog tso siab rau lub arc cua sov uas tsim los ntawm lub vuam pas nrig lossis hlau thiab cov khoom ua haujlwm kom yaj cov hlau. Txawm hais tias arc vuam siv dav thiab hloov tau yooj yim hauv cov phaj tuab welding, nws yog qhov tsis txaus nyob rau hauv nyias phaj vuam. Vim hais tias cov cua sov tsim los ntawm arc vuam yog sib cais thiab kav ntev, xws li siv lub 'loj torch' ci nyias daim hlau, nws yog ib qho yooj yim ua rau lub zos overheating ntawm daim hlau nyias, ua rau deformation, undercutting, thiab txawm hlawv los ntawm, uas cuam tshuam rau lub vuam zoo.

Txawm li cas los xij, arc vuam kuj muaj nws qhov zoo. Nws tuaj yeem muaj txiaj ntsig zoo hauv cov cheeb tsam nyuaj xws li tuab phaj vuam thiab kev tsim kho, tab sis nws yog me ntsis qis dua nyob rau hauv cov xwm txheej tshwj xeeb ntawm nyias phaj vuam.

Hauv cov ntsiab lus, xaiv cov vuam vuam rau nyias phaj vuam zoo li tsim kom muaj qhov tseeb thiab ua tau zoo 'tsuas yog vuam lub rooj zaum' rau nyias daim hlau, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm nyias daim hlau nyob rau hauv cov nqe lus ntawm kev ua tau zoo, kev ua tau zoo, zoo li, thiab lwm yam. Tsis xav tias nws tau dhau los ua cov kev daws teeb meem rau nyias phaj vuam.
