Yuav kom nkag siab txog lithium roj teeb qhov chaw vuam tshuab, ces peb yuav tsum pib los ntawm nws qhov chaw tiv thaiv vuam tshuab.
Txhais cov ntsiab lus ntawm kev siv vuam vuam: txoj kev vuam los ntawm kev siv lub zog los ntawm cov electrode tom qab vuam sib xyaw ua ke, thiab cov cua sov ua haujlwm tau tsim los ntawm qhov tam sim no dhau los ntawm kev sib cuag ntawm qhov sib koom tes thiab qhov chaw nyob ib sab kuj hu ua kev sib cuag vuam. Thaum ua hauj lwm, ob lub electrodes nyem lub workpiece, kom ob txheej hlau (hlau thiab roj teeb zoo thiab tsis zoo electrodes) tsim ib tug tej yam kev tiv thaiv nyob rau hauv lub siab ntawm ob electrodes. Thaum lub vuam tam sim no ntws los ntawm ib lub tshuab hluav taws xob mus rau lwm qhov, cov vuam thermal tam sim no yog tsim los ntawm ob lub ntsiab lus tiv thaiv, thiab cov vuam tam sim no ntws tam sim ntawd raws li ob lub tshuab ua haujlwm los ntawm lwm cov electrode, tsim lub voj tsis muaj kev puas tsuaj sab hauv ntawm lub workpiece. yuav tsum welded.
Cov yam ntxwv tseem ceeb ntawm kev tiv thaiv vuam:
(1) Lub vuam hluav taws xob tsawg heev (1 ~ 12V), qhov vuam tam sim no loj heev (txog ~ phav phav amps, amperes), thiab lub sijhawm vuam los ua kom tiav ib qho kev sib koom yog luv heev (0.01 ~ ob peb vib nas this), yog li cov khoom tsim tau siab.
(2) Thaum tshav kub kub, kev siv tshuab siab yog siv rau kev sib koom ua ke, thiab kev sib koom ua ke yog welded nyob rau hauv qhov kev txiav txim siab, yog li tsis tas yuav sau cov hlau thaum vuam.
Resistance welding yog muab faib ua qhov chaw vuam, seam welding, convex vuam thiab taub qab vuam raws li cov txheej txheem sib txawv.
Lub lithium roj teeb qhov chaw vuam tshuab kuj yog ib hom kev tiv thaiv vuam.
Spot welding yog ib txoj hauv kev ua haujlwm vuam uas cov vuam sib txuas sib txuas thiab nias ntawm ob lub electrodes, thiab siv cov kev tiv thaiv kom sov yaj lub hauv paus hlau los ua ib qho kev sib koom ua ke. Spot welding feem ntau yog siv rau kev sib txuas ntawm daim hlau nyias.
Txheej txheem ntawm qhov chaw welding:
(1) Pre-pressurization los xyuas kom meej kev sib cuag zoo ntawm workpiece.
(2) Tig rau hluav taws xob los ua ib qho molten core thiab ib lub nplhaib yas ntawm qhov vuam.
(3) Fais fab tuag forging thiab nias, kom lub molten core txias thiab crystallizes nyob rau hauv lub siab los tsim ib tug solder sib koom nrog ntom qauv, tsis muaj shrinkage qhov thiab tawg.
Spot vuam txheej txheem tsis xws li vuam tam sim no, electrode siab, lub zog ntawm lub sij hawm thiab electrode ua hauj lwm saum npoo loj muaj feem cuam tshuam rau vuam zoo.
