Nyob rau hauv tus txheej txheem ntawm nruab nrab zaus inverter qhov chaw vuam, tsim ntawm fusion nugget plays lub luag haujlwm tseem ceeb hauv kev ua tiav qhov muaj zog thiab txhim khu kev qha.Qhov tsab xov xwm no aims los piav qhia lub tswvyim ntawm ib tug fusion nugget thiab delve rau hauv cov txheej txheem ntawm nws tsim nyob rau hauv nruab nrab zaus inverter chaw welding.
- Fusion Nugget: Lub fusion nugget yog hais txog thaj chaw hauv cheeb tsam ntawm cov khoom molten uas tsim thaum lub sij hawm vuam txheej txheem.Nws yog qhov tshwm sim ntawm cov cua kub hnyav uas tsim los ntawm hluav taws xob tsis kam ntawm cov khoom ua haujlwm thiab cov khoom siv vuam tam sim no.Lub fusion nugget yog lub luag haujlwm rau kev koom nrog cov khoom ua haujlwm ua ke, tsim kom muaj kev sib koom ua ke thiab ruaj khov.
- Cov txheej txheem ntawm Fusion Nugget Tsim: Kev tsim ntawm fusion nugget nyob rau hauv nruab nrab zaus inverter chaw vuam muaj ntau theem:
a.Kev sib cuag thiab Compression: Cov workpieces yuav tsum tau welded yog coj mus rau hauv kev sib cuag thiab compressed ua ke los ntawm electrode quab yuam.Qhov no ua kom muaj kev sib cuag zoo thiab tsim txoj hauv kev rau cov vuam tam sim no.
b.Cua sov: Thaum lub workpieces nyob rau hauv kev sib cuag, ib tug siab vuam tam sim no dhau los ntawm lawv.Cov hluav taws xob tsis kam ntawm lub interface ua kom sov, nce qhov kub thiab txias ntawm qhov chaw sib cuag.Cov cua sov ua rau cov khoom muag muag thiab thaum kawg yaj, tsim lub pas dej molten.
c.Kev sib xyaw thiab kev sib xyaw ua ke: Raws li cov vuam tam sim no txuas ntxiv mus, cov khoom siv molten los ntawm ob qho tib si workpieces sib xyaw ua ke hauv lub pas dej molten.Qhov no txhawb nqa qhov sib txawv ntawm cov atoms thiab pab txhawb kev tsim cov hlau nplaum ntawm cov khoom siv ua haujlwm.Lub pas dej molten ces pib solidify thaum tshav kub dissipates, tsim cov fusion nugget.
d.Cooling thiab Solidification: Tom qab lub vuam tam sim no raug tua, fusion nugget pib txias thiab solidify.Tus nqi cua txias cuam tshuam rau microstructure thiab mechanical zog ntawm vuam.Kev tswj cua txias tso cai rau kev tsim cov txheej txheem metallurgical uas xav tau thiab ua kom muaj zog vuam zoo.
- Cov yam ntxwv cuam tshuam rau Fusion Nugget Tsim: Ntau yam tuaj yeem cuam tshuam qhov tsim ntawm fusion nugget hauv nruab nrab zaus inverter qhov chaw vuam:
- Vuam tam sim no: Qhov loj ntawm qhov vuam tam sim no ncaj qha cuam tshuam rau lub tshav kub tiam thiab, yog li, qhov loj thiab qhov tob ntawm fusion nugget.
- Electrode quab yuam: Lub siab thov txiav txim qhov chaw sib cuag ntawm cov khoom ua haujlwm, cuam tshuam rau kev faib hluav taws xob thiab tsim nugget.
- Vuam lub sij hawm: Lub sijhawm ntawm cov txheej txheem vuam cuam tshuam rau cov khoom siv hluav taws xob thiab qhov loj ntawm fusion nugget.
- Cov khoom siv: Cov conductivity, thickness, thiab muaj pes tsawg leeg ntawm cov ntaub ntawv workpiece cuam tshuam lawv cov tsis kam mus rau tam sim no ntws thiab, yog li ntawd, lub tshav kub tiam thiab fusion nugget tsim.
Lub fusion nugget yog ib qho tseem ceeb hauv kev ua tiav qhov kev vam meej hauv nruab nrab zaus inverter qhov chaw vuam.Nkag siab txog cov txheej txheem ntawm fusion nugget tsim thiab cov yam ntxwv cuam tshuam nws tuaj yeem pab txhim kho vuam tsis zoo, tswj cov vuam zoo, thiab ua kom lub zog thiab ua haujlwm ntev ntawm cov vuam sib txuas.Los ntawm kev ua tib zoo tswj cov vuam tam sim no, electrode quab yuam, vuam lub sij hawm, thiab cov khoom siv, cov welders tuaj yeem ua tiav thiab txhim khu kev qha fusion nugget tsim, ua rau qhov zoo tshaj plaws welds.
