Kev tiv thaiv vuam yog cov txheej txheem siv dav hauv kev tsim khoom, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas qhov tseeb, siab -welds zoo yuav tsum tau. Nws cuam tshuam txog kev tsim hluav taws xob los ntawm kev hla cov hluav taws xob tam sim no los ntawm cov khoom ua haujlwm, nrog rau qhov tsis kam ntawm cov khoom siv welded hloov hluav taws xob hluav taws xob rau hauv tshav kub, yog li tsim kom muaj kev sib raug zoo. Cov txheej txheem no muaj ntau yam, tsim nyog rau ntau yam khoom siv, thiab muaj ntau yam zoo ntawm kev ceev, tus nqi - efficiency, thiab precision. Kab lus no delves rau hauv cov hauv paus ntsiab lus, kev siv, qhov zoo, thiab kev txwv ntawm kev siv vuam tsis kam.
Lub hauv paus ntsiab lus ntawm Resistance Vuam
Nyob rau hauv lub hauv paus ntawm kuj welding lies lub hloov dua siab tshiab ntawm hluav taws xob zog mus rau hauv tshav kub los ntawm hluav taws xob kuj. Cov txheej txheem feem ntau suav nrog cov kauj ruam hauv qab no:
Kev siv lub siab: Ob lub electrodes tau muab tso rau ntawm ob sab ntawm cov ntaub ntawv yuav tsum tau koom nrog. Lub siab yog siv los tuav lub workpieces ua ke thaum lub sij hawm vuam txheej txheem. Lub siab no ua kom cov ntaub ntawv tseem nyob hauv kev sib cuag thiab pab tsim kom muaj kev sib txuas hluav taws xob zoo.
Passage ntawm Hluav Taws Xob: Ib qho hluav taws xob siab dhau los ntawm cov khoom siv, thiab vim muaj qhov tsis kam ntawm cov ntaub ntawv, cua sov yog tsim los ntawm qhov sib cuam tshuam ntawm lawv. Qhov cua sov no ua rau cov hlau ntawm cov ntsiab lus sib cuag kom yaj, ua rau lub weld nugget.
Cooling thiab Solidification: Tom qab qhov hluav taws xob tau muab tua, cov cua sov dissipates, thiab cov hlau molten solidifies, tsim kom muaj kev ruaj khov, ruaj khov. Cov txheej txheem cua txias yog qhov tseem ceeb rau qhov zoo ntawm cov vuam, vim nws txiav txim siab lub zog thiab ua haujlwm ntev ntawm kev sib koom ua ke.
Peb hom tseem ceeb ntawm cov txheej txheem welding yog:
Spot Vuam: Ib txheej txheem uas cov vuam yog ua ntawm cov chaw me me.
Seam Vuam: Zoo ib yam li qhov chaw vuam tab sis muaj kev txuas txuas txuas ntxiv raws li cov seam.
Butt Vuam: Kev sib koom ua ke ntawm ob lub workpieces los ntawm kev siv lub siab thiab tam sim no hla qhov kawg ntawm cov ntaub ntawv.
Cov cuab yeej siv hauv kev ua haujlwm vuam
Kev tiv thaiv vuam xav tau cov cuab yeej tshwj xeeb los xyuas kom muaj kev ua tiav ntawm cov txheej txheem vuam. Cov khoom tseem ceeb muaj xws li:
Cov hluav taws xob: Ua los ntawm siab -cov ntaub ntawv conductivity zoo li tooj liab, electrodes yog siv los siv lub siab thiab ua hluav taws xob tam sim no rau cov khoom ua haujlwm. Kev tsim thiab cov khoom siv ntawm cov electrodes ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo ntawm qhov vuam.
Hloov pauv: Ib kauj ruam -down transformer feem ntau yog siv rau hauv kev sib txuas vuam kom txo tau qhov hluav taws xob nkag mus rau qib tsim nyog rau vuam thaum nce qhov tam sim no. Lub transformer yuav tsum tau ua tib zoo tsim los tswj cov kev xav tau ntawm lub zog ntawm cov txheej txheem.
Tswj System: Lub kaw lus tswj yog qhov tseem ceeb los tswj lub sijhawm, tam sim no, thiab lub zog siv thaum lub sijhawm vuam. Cov tshuab niaj hnub no yog siv computer thiab muaj peev xwm muab kev tswj xyuas kom meej, ua kom muaj -welds zoo.
Txias System: Txij li cov electrodes tuaj yeem ua kom sov sai, lub tshuab ua kom txias (feem ntau siv dej) yog kev sib xyaw kom tsis txhob muaj cua sov thiab ua kom lub neej ntev ntawm cov khoom siv.
