Peb lub ntsiab tseem ceeb ntawm Resistance Spot Welding

Resistance chaw vuam yog ib qho kev siv dav hauv kev tsim khoom, paub txog nws cov txiaj ntsig thiab kev ntseeg tau.Txhawm rau ua tiav cov welds zoo, peb lub ntsiab lus tseem ceeb ua lub luag haujlwm tseem ceeb hauv cov txheej txheem: tam sim no, lub sijhawm, thiab lub zog.

1. Tam sim no: Thawj lub ntsiab lus, tam sim no, yog hais txog lub zog hluav taws xob muab rau kev ua haujlwm vuam.Nyob rau hauv qhov chaw tsis kam vuam, ob lub electrodes clamp lub workpieces ua ke, thiab cov hluav taws xob siab dhau los ntawm lawv.Qhov tam sim no generates tshav kub vim hluav taws xob tsis kam ntawm cov ntaub ntawv raug koom.Tus nqi ntawm cov ntaub ntawv tam sim no yuav tsum tau ua tib zoo tswj, raws li nws ncaj qha cuam tshuam qhov kub ntawm qhov vuam cheeb tsam.Tam sim no ntau dhau tuaj yeem ua rau overheating thiab puas, thaum me me tuaj yeem ua rau tsis tiav welds.
2. Sijhawm: Lub ntsiab tseem ceeb thib ob yog lub sijhawm, uas sib haum rau lub sijhawm ntawm cov dej ntws tam sim no los ntawm cov khoom ua haujlwm.Lub sij hawm tam sim no yog siv los txiav txim qhov nyiaj ntawm cov cua sov tsim thiab, yog li ntawd, qhov tob ntawm vuam.Daim ntawv thov raws sij hawm tam sim no ua kom cov ntaub ntawv yaj thiab fuse ua ke kom raug.Lub sijhawm luv luv tuaj yeem ua rau cov welds tsis muaj zog, thaum lub sijhawm ntau dhau tuaj yeem ua rau muaj cua sov ntau dhau thiab ua rau cov khoom puas tsuaj.
3. Siab: Thaum kawg, lub siab yog lub zog siv rau lub workpieces thaum vuam.Lub siab yog qhov tseem ceeb los xyuas kom muaj kev sib raug zoo ntawm cov ntaub ntawv uas tau koom nrog.Lub siab zoo pab tshem tawm cov kab mob thiab oxides los ntawm qhov chaw vuam, tso cai rau kom muaj qhov huv thiab ruaj khov.Kev tsis txaus siab tuaj yeem ua rau tsis zoo weld zoo, thaum lub siab ntau dhau tuaj yeem ua rau deformation lossis txawm tias perforation ntawm workpieces.

Hauv kev xaus, qhov chaw vuam tsis kam tso siab rau kev ua tib zoo tswj tam sim no, lub sijhawm, thiab lub siab los tsim cov pob qij txha muaj zog thiab txhim khu kev qha.Peb lub ntsiab lus no yuav tsum raug ntsuas kom meej kom haum rau cov ntaub ntawv tshwj xeeb thiab cov thicknesses raug welded.Thaum ua tiav kom raug, qhov chaw welding muaj qhov ua tau zoo thiab muaj txiaj ntsig zoo rau kev koom nrog ntau yam hlau, ua rau nws yog cov txheej txheem tseem ceeb hauv kev tsim khoom niaj hnub.
