Weld me ntsis ua lub luag haujlwm tseem ceeb hauv nruab nrab zaus inverter chaw vuam, muab cov pob qij txha muaj zog thiab txhim khu kev qha ntawm ob qhov chaw hlau. Nkag siab txog cov txheej txheem ntawm kev tsim cov khoom siv vuam yog qhov tseem ceeb rau kev ua kom zoo dua cov vuam tsis zoo, ua kom cov welds zoo, thiab ua tiav cov khoom xav tau. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv lub mechanism tom qab tsim ntawm weld me ntsis nyob rau hauv nruab nrab-frequency inverter chaw welding.
- Kev sib cuag thiab Compression: Thawj kauj ruam hauv kev tsim qhov chaw weld yog tsim kev sib cuag thiab compression ntawm cov lus qhia electrode thiab cov khoom ua haujlwm. Raws li cov electrodes mus txog qhov chaw ua haujlwm, lub siab yog siv los tsim kev sib cuag nruj. Lub compression ua kom muaj kev sib raug zoo thiab tshem tawm txhua qhov khoob lossis cov hnab ntim cua uas tuaj yeem cuam tshuam nrog cov txheej txheem vuam.
- Resistance Heating: Thaum cov electrodes tsim kev sib cuag, ib qho hluav taws xob tam sim no tau dhau los ntawm qhov chaw ua haujlwm, ua kom muaj cua sov ua haujlwm. Lub siab tam sim no ceev ntawm qhov chaw sib cuag ua rau cov cua sov hauv cheeb tsam vim qhov hluav taws xob tsis kam ntawm cov khoom siv ua haujlwm. Qhov kub siab no nce qhov kub ntawm qhov chaw sib cuag, ua rau cov hlau muag muag thiab nws thiaj li ncav cuag nws qhov melting point.
- Hlau Melting thiab Bonding: Raws li qhov kub thiab txias, cov hlau ntawm qhov chaw sib cuag pib yaj. Thaum tshav kub kub yog kis los ntawm lub workpiece mus rau cov lus qhia electrode, uas ua rau lub zos melting ntawm ob lub workpiece thiab cov khoom siv electrode. Cov hlau molten tsim ib lub pas dej ua ke ntawm qhov chaw sib cuag, tsim kom muaj cov theem ua kua.
- Solidification thiab Solid-State Bonding: Tom qab lub pas dej molten hlau yog tsim, nws pib solidify. Raws li cov cua kub dissipates, cov kua hlau ua kom txias thiab nkag mus rau solidification, hloov rov qab mus rau nws lub zog. Thaum lub sij hawm no solidification txheej txheem, atomic diffusion tshwm sim, tso cai rau lub atoms ntawm lub workpiece thiab electrode cov ntaub ntawv rau intermix thiab tsim metallurgical bonds.
- Weld Spot Formation: Lub solidification ntawm cov hlau molten tshwm sim nyob rau hauv tsim ntawm ib tug solidified weld chaw. Qhov chaw weld yog thaj chaw sib koom ua ke uas cov khoom siv ua haujlwm thiab cov khoom siv hluav taws xob tau sib xyaw ua ke, tsim kom muaj kev sib koom ua ke muaj zog thiab ruaj khov. Qhov loj thiab cov duab ntawm qhov chaw vuam yog nyob ntawm ntau yam xws li vuam tsis, tsim electrode, thiab cov khoom siv.
- Tom qab Weld Cooling thiab Solidification: Tom qab qhov chaw vuam tau tsim, cov txheej txheem txias tseem txuas ntxiv. Lub tshav kub dissipates los ntawm qhov chaw weld mus rau qhov chaw ib puag ncig, thiab cov hlau molten solidifies tag nrho. Qhov txias txias thiab solidification theem no yog qhov tseem ceeb rau kev ua tiav cov khoom siv hlau xav tau thiab ua kom muaj kev ncaj ncees ntawm kev sib koom ua ke.
Kev tsim cov chaw vuam hauv nruab nrab zaus inverter qhov chaw vuam yog cov txheej txheem nyuaj uas muaj kev sib cuag thiab compression, tiv thaiv cua sov, hlau melting thiab kev sib txuas, solidification, thiab tom qab vuam txias. Kev nkag siab txog cov txheej txheem no yuav pab txhim kho vuam tsis zoo, tswj qhov zoo ntawm qhov chaw vuam, thiab xyuas kom muaj zog thiab kev ncaj ncees ntawm cov pob qij txha. Los ntawm kev ua tib zoo tswj cov vuam tsis zoo thiab ua kom muaj kev tsim hluav taws xob tsim nyog thiab xaiv cov khoom siv, cov tuam ntxhab tuaj yeem tsim cov khoom siv vuam zoo nyob rau hauv nruab nrab zaus inverter qhov chaw vuam daim ntaub ntawv.
