Hauv nruab nrab zaus inverter qhov chaw vuam tshuab, daim ntawv thov ntawm siab yog ib qho tseem ceeb hauv cov txheej txheem vuam. Lub siab siv nruab nrab ntawm cov electrodes thiab workpieces cuam tshuam qhov zoo thiab lub zog ntawm qhov sib koom ua ke. Kab lus no tham txog cov theem koom nrog hauv cov txheej txheem kev thov siab hauv nruab nrab zaus inverter chaw vuam tshuab.
- Kev Sib Txuas Thaum Pib: Thawj theem ntawm daim ntawv thov siab yog thawj zaug sib cuag ntawm cov electrodes thiab cov khoom ua haujlwm:
- Cov electrodes raug coj mus rau hauv kev sib cuag nrog cov workpieces, kom ntseeg tau tias kev sib raug zoo thiab qhov chaw.
- Lub teeb pib siab yog siv los tsim kev sib cuag hluav taws xob thiab tshem tawm cov kab mob los yog oxide txheej.
- Pre-Compression Stage: Lub pre-compression theem yuav maj mam nce lub siab thov:
- Lub siab yog nce tsis tu ncua kom ua tiav qib txaus rau kev siv vuam zoo.
- Cov theem no ua kom muaj kev sib cuag ntawm electrode-to-workpiece thiab npaj cov ntaub ntawv rau cov txheej txheem vuam.
- Lub pre-compression theem yuav pab tshem tawm tej huab cua sib txawv los yog irregularities ntawm lub electrodes thiab workpieces, kom ntseeg tau ib tug zoo ib yam weld.
- Vuam Theem: Thaum lub siab xav tau mus txog, lub vuam theem pib:
- Cov electrodes ua kom zoo ib yam thiab tswj kev ua haujlwm ntawm cov khoom ua haujlwm thoob plaws hauv cov txheej txheem vuam.
- Lub vuam tam sim no yog siv, ua kom sov ntawm electrode-rau-workpiece interface, uas ua rau lub zos melting thiab tom qab weld tsim.
- Lub vuam theem feem ntau muaj lub sijhawm teev tseg raws li qhov ntsuas vuam thiab cov khoom siv.
- Post-Compression Stage: Tom qab vuam theem, ib theem tom qab compression raws li nram no:
- Lub siab yog tswj xyuas lub sijhawm luv luv kom tso cai rau kev sib koom ua ke thiab txias ntawm qhov sib koom ua ke.
- Cov theem no yuav pab kom muaj kev sib xyaw ua ke thiab kev sib koom ua ke ntawm cov hlau molten, txhim kho lub zog thiab kev ncaj ncees ntawm cov vuam.
Daim ntawv thov siab nyob rau hauv nruab nrab zaus inverter qhov chaw vuam tshuab koom nrog ntau theem, txhua tus ua haujlwm tshwj xeeb hauv cov txheej txheem vuam. Thawj theem kev sib cuag tau tsim kev sib cuag electrode-rau-workpiece, thaum lub sij hawm ua ntej compression ua kom muaj kev sib raug zoo thiab tshem tawm cov pa tawm. Lub vuam theem siv lub siab sib xws thaum lub vuam tam sim no ua kom sov rau kev tsim vuam. Thaum kawg, tom qab-compression theem tso cai rau solidification thiab txias ntawm lub vuam sib koom ua ke. Kev nkag siab thiab ua tiav txhua theem ntawm kev thov siab yog qhov tseem ceeb rau kev ua tiav cov vuam zoo nrog lub zog zoo thiab kev ncaj ncees hauv nruab nrab zaus inverter qhov chaw vuam tshuab.
