Resistance spot welding yog ib txoj kev tsim khoom siv dav siv uas koom nrog ob lossis ntau cov ntawv hlau ua ke los ntawm kev siv cua sov thiab siab ntawm cov ntsiab lus tshwj xeeb.Txhawm rau ua qhov haujlwm no kom zoo, qhov chaw vuam tshuab yuav tsum muaj kev ntseeg siab ntawm lub zog hluav taws xob.Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog ntau yam kev siv hluav taws xob uas feem ntau ua haujlwm hauv cov khoom siv vuam tshuab.
- Direct Current (DC) Fais fab mov:
- DC fais fab tuag yog txoj kev siv ntau tshaj plaws thiab ib txwm siv hauv qhov chaw vuam.Nws muaj kev tswj xyuas meej tshaj qhov ntsuas qhov ntsuas.
- Hauv DC qhov chaw vuam, ib qho ncaj qha tam sim no dhau los ntawm cov vuam electrodes.Qhov tam sim no ua kom sov ntawm qhov chaw vuam, ua rau cov hlau yaj thiab fuse ua ke.
- Alternating Current (AC) Fais fab mov:
- AC fais fab mov tsis tshua siv tab sis muaj nws qhov zoo, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas xav tau ib qho softer weld.
- AC qhov chaw vuam muab cov cua kub zoo sib xws, uas tuaj yeem txo qhov kev pheej hmoo ntawm overheating thiab warping nyob rau hauv tej yam ntaub ntawv.
- Inverter-based fais fab mov:
- Inverter thev naus laus zis tau dhau los ua neeg nyiam nyob rau hauv qhov chaw vuam tshuab vim nws lub zog ua haujlwm thiab ntau yam.
- Inverter-raws li cov khoom siv hluav taws xob hloov hluav taws xob AC nkag mus rau hauv cov zis DC tswj, muab cov txiaj ntsig ntawm ob qho tib si DC thiab AC vuam.
- Capacitor Discharge Vuam (CDW):
- CDW yog ib txoj kev tshwj xeeb uas tsim nyog rau kev ua haujlwm me me thiab me me vuam.
- Hauv CDW, lub zog yog khaws cia hauv lub txhab nyiaj capacitor thiab tom qab ntawd tawm sai sai los ntawm cov vuam electrodes, tsim kom muaj luv luv tab sis khaus vuam arc.
- Pulsed vuam:
- Pulsed welding yog ib qho kev tsim kho tshiab niaj hnub uas sib txuas qhov zoo ntawm DC thiab AC vuam.
- Nws cuam tshuam nrog kev sib tsoo ntawm lub zog uas tso cai rau kev tswj xyuas meej ntawm cov txheej txheem vuam thaum txo cov cua sov nkag.
- Medium-Frequency Inverter Vuam:
- Txoj kev no feem ntau siv hauv kev tsim tsheb thiab lwm yam kev siv vuam ceev.
- Medium-frequency welding muab lub zog hloov pauv sai, txo lub sijhawm tag nrho lub sijhawm rau qhov chaw vuam.
Txhua txoj kev siv hluav taws xob no muaj nws qhov zoo thiab qhov tsis muaj zog, ua rau lawv tsim nyog rau kev siv vuam tshwj xeeb.Qhov kev xaiv ntawm cov khoom siv hluav taws xob yog nyob ntawm yam xws li hom khoom siv welded, qhov xav tau weld zoo, ntau lawm ceev, thiab kev siv hluav taws xob xav tau.
Hauv kev xaus, qhov chaw vuam tshuab tuaj yeem siv tau los ntawm ntau txoj hauv kev, txhua qhov muab cov txiaj ntsig tshwj xeeb kom tau raws li cov kev xav tau sib txawv ntawm kev tsim khoom.Kev xaiv ntawm txoj kev siv hluav taws xob tsim nyog yog qhov tseem ceeb hauv kev ua kom zoo thiab ua haujlwm ntawm qhov chaw vuam txheej txheem.
