- Tshaj tam sim no ua rau tawg thiab cov khoom puas tsuaj
- Cov khoom siv - cov cai tshwj xeeb: 12-14A / mm² rau stainless hlau vs 8-10A / mm² rau cov hlau me me
2.Lub sijhawm vuam zoo
- Cov ntaub ntawv nyias (cov ntawv galvanized): 15-30ms cycles
- Cov ntaub ntawv tuab: 50-100ms nrog ntau theem tswj
- Advanced mus kom ze: Preheat-weld- temper sequences txo thermal stress
3.Electrode Pressure Management
- Tsis tshua muaj siab ua rau muaj kev tiv thaiv tiv thaiv thiab overheating txaus ntshai
- Kev kub siab collapses nuggets thiab txo lub zog
- Cov lus qhia tswv yim: Siab (N)=Khoom thickness (mm) × 50
Cov khoom siv kho mob thiab kho
Kojqhov chaw vuam tshuabxav tau kev saib xyuas zoo ib yam rau kev ua haujlwm zoo:
1.Electrode kev ncaj ncees
- Qhov chaw paug ua rau muaj hluav taws xob tiv thaiv
- Kev tu thiab hloov tsis tu ncua ua kom muaj kev ruaj ntseg tam sim no
- Ua raws li kev teem caij hnav khaub ncaws raws li qhov ntim ntau lawm
2.Cooling System Efficiency
- Tsis txaus txaus ua rau cov khoom siv overheating
- Kev saib xyuas dej kub thiab siab tsis tu ncua
- Khaws cov khoom siv hluav taws xob kom huv si kom zoo tshaj plaws dissipation
3. Fais fab mov ruaj khov
- Voltage fluctuations ncaj qha cuam tshuam vuam tam sim no
- Cov cuab yeej ruaj khov lossis MFDC thev naus laus zis (1-5kHz) txhim kho qhov sib xws
- Kev tshuaj xyuas tsis tu ncua ntawm cov khoom siv hluav taws xob zoo
Cov yam ntxwv ntawm cov khoom siv thiab kev npaj
Qhov chaw vuam tshuab yuav tsum tau yoog rau cov khoom siv tshwj xeeb:
1. Lub cev muaj zog
- Conductivity thiab melting ntsiab lus sib txawv heev
- Aluminium yuav tsum tau ceev vuam voj voog (1-2 vib nas this siab tshaj)
- Kev txhim kho Parameter los ntawm kev sim ua haujlwm
2.Ntoo yam mob
- Cov oxides thiab cov kab mob paug thaiv cov dej ntws tam sim no
- Ua ntej- vuam vuam yog qhov tseem ceeb rau cov txiaj ntsig zoo ib yam
- Kev tiv thaiv huab cua (argon) txo oxidation
Environmental and Operational Factors
Cov xwm txheej sab nraud cuam tshuam rau koj qhov chaw vuam tshuab kev ua haujlwm:
1.Environmental Control
- Cov kub kub sib tw cua txias tshuab
- Humidity ua rau nto condensation thiab kuj hloov pauv
- Ua haujlwm ruaj khov thaum ua tau
2.Txoj kev sib thooj
- Cov txheej txheem kev ua haujlwm tau zoo txo qis kev sib txawv
- Kev cob qhia tus neeg ua haujlwm kom paub meej parameter adherence
- Cov ntaub ntawv ntawm kev pom zoo rau txhua daim ntawv thov
Kev Ua Haujlwm Zoo
Rau cov txiaj ntsig zoo ib yam nrog koj qhov chaw vuam tshuab:
- Tsim kom muaj lub sijhawm ua pov thawj tsis tu ncua
- Siv cov txheej txheem tswj xyuas cov txheej txheem
- Ua qhov kev kuaj xyuas kev puas tsuaj raws sij hawm
- Khaws cov ntaub ntawv saib xyuas cov cuab yeej zoo
Xaus
Ua kom tau raws li qhov zoo sib xws nrog MFDC qhov chaw vuam tshuab yuav tsum tau saib xyuas ntau yam sib cuam tshuam. Los ntawm kev tswj xyuas qhov tseeb, kev saib xyuas cov cuab yeej siv tau zoo, kev npaj cov khoom tsim nyog, thiab kev ua haujlwm ruaj khov, cov tuam txhab tuaj yeem ua kom muaj txiaj ntsig zoo thiab tsim khoom.
Cov yooj yooj yim thiab tswj tau muab los ntawm niaj hnubqhov chaw vuam tshuabthev naus laus zis, thaum siv tau zoo, ua rau cov tuam txhab ua kom tau raws li qhov xav tau ntawm cov qauv kev ua tau zoo thaum tswj hwm kev ua haujlwm ntawm ntau yam kev siv thiab cov khoom siv.
