Cov txheej txheem Vuam: Resistance Vuam

Resistance welding yog ib pawg ntawm cov txheej txheem vuam nyob rau hauv uas lub tshav kub thiab siab generated los ntawm kev ua hauj lwm ntawm lub workpieces mus rau tam sim no nyob rau hauv ib tug hluav taws xob Circuit Court tsim lub fusion. Muaj tsawg kawg yog xya qhov tseem ceeb ntawm cov txheej txheem welding. Cov no yog flash welding, siab zaus kuj welding, cuam tshuam vuam, projection welding, kuj seam vuam, kuj qhov chaw vuam, thiab sab saum toj vuam. Lawv zoo sib xws nyob rau hauv ntau txoj kev, tab sis kuj txawv heev.
Resistance spot welding (RSW) yog cov txheej txheem vuam tsis kam uas ua rau fusion ntawm qhov sib koom ua ke ntawm ib qho chaw los ntawm cov cua sov uas tsim los ntawm kev ua haujlwm ntawm cov khoom ua haujlwm tuav ua ke nyob rau hauv siab los ntawm electrodes mus rau tam sim no.
Qhov loj thiab cov duab ntawm cov weld tsim ib tus zuj zus yog tsuas yog txwv los ntawm qhov loj thiab qhov profile ntawm cov electrodes. Resistance chaw vuam cov cuab yeej tuaj yeem ua tau yooj yim thiab pheej yig, tab sis kuj tuaj yeem ua ntau qhov chaw welders loj heev. Tsau ib qho chaw welder feem ntau yog ob hom: horn lossis rocker hom thiab nias hom.
Resistance seam welding (RSEW) yog cov txheej txheem welding tsis kam uas fuses qhov sib koom ua ke los ntawm kev tsim cov cua sov los ntawm kev ua haujlwm ntawm cov khoom ua haujlwm tuav ua ke los ntawm electrodes nyob rau hauv siab rau cov hluav taws xob tam sim no.
Lub resulting weld yog ib tug series ntawm overlapping kuj qhov chaw welds uas tsim maj mam nyob rau hauv lub sib koom tes ntawm lub rotating electrode. Thaum qhov chaw welds tsis sib tshooj txaus los tsim cov roj teeb vuam, qhov no yog qhov hloov pauv hu ua rolling resistance spot welding. Cov txheej txheem sib txawv ntawm qhov chaw vuam nyob rau hauv uas cov electrodes yog lub log. Ob lub sab sauv thiab qis electrode log yog energized. Lub siab yog siv nyob rau hauv tib yam li nyob rau hauv ib tug yob welder. Cov log tuaj yeem ua rau hauv kab nrog caj pas ntawm lub tshuab lossis transversely. Yog tias lawv nyob hauv kab, nws feem ntau hu ua longitudinal seam welder. Lub vuam tam sim no kis tau los ntawm cov bearings ntawm cov menyuam electrode log. Tsis muaj dej txias rau sab hauv, yog li qhov chaw vuam yog dej nyab nrog cov dej txias kom cov electrode log txias.
