Ib qhov tas li hluav taws xob , cov khoom siv hluav taws xob ncaj qha tam sim no feem ntau siv nrog GMAW, tab sis cov tshuab tam sim no, nrog rau kev hloov tam sim no, tuaj yeem siv tau. Muaj plaub txoj hauv kev hloov hlau hlau hauv GMAW: Globular. Short-circuiting.
Dhau li, plaub hom kev siv fais fab txuas yog dab tsi?
Cov txheej txheem vuam arc feem ntau yog:
- Shielded Hlau Arc Vuam (SMAW),
- Gas Tungsten Arc Vuam (GTAW lossis Tig),
- Gas Metal Arc Vuam (GMAW or Mig),
- Flux Cored Arc Vuam (FCAW),
- Submerged Arc Vuam (SAW) thiab.
- Plasma Arc Vuam (PAW).
Dab tsi ntawm cov khoom siv hluav taws xob yog tsim los ntawm MIG MAG vuam teeb? MIG (Hlau Inert Gas) vuam yog a vuam txheej txheem uas ib hluav taws xob arc daim ntawv nruab nrab ntawm cov khoom siv hluav taws xob siv hluav taws xob thiab cov khoom ua haujlwm. Cov txheej txheem no siv cov pa roj inert lossis cov dej sib xyaw ua cov pa tiv thaiv. Argon thiab helium feem ntau yog siv rau cov MIG welding ntawm non-ferrous hlau xws li aluminium.
Ua li no, yam twg tam sim no siv hauv MIG vuam?
MIG Qhov hluav taws xob Hom thiab Vuam Polarity MIG welding tsis zoo li lwm yam vuam cov txheej txheem muaj ib tus qauv voltage yam thiab polarity yam . Qhov voltage siv yog DC direct tam sim no , zoo li cov tam sim no hauv tsheb roj teeb. Ncaj nraim tam sim no ntws hauv ib qho kev taw qhia, los ntawm qhov tsis zoo (-) mus rau qhov zoo (+).
Dab tsi ntawm electrode hlau siv nrog GMAW?
GMAW xav tau ib qho khoom hlau electrode los yog sib xyaw hlau-cored electrode . Khoom hlau electrodes feem ntau yog hu ua GMAW electrodes . Cov khoom siv kho tshuab thiab lub zog ntawm cov khoom siv vuam yog nyob ntawm thawj zaug ntawm chemistry ntawm lub xaim thiab thib ob ntawm lub yam tiv thaiv roj siv (saib daim duab 1).

Hom hlau twg siv hauv MIG vuam?
MIG cov khoom siv hluav taws xob siv cov khoom siv hluav taws xob txuas ntxiv mus rau cov hlau muab tub lim thiab yuav tsum muaj cov roj thaiv kev xa tawm los ntawm lub raj mis roj. Cov hlau me me feem ntau yog plated nrog tooj liab los tiv thaiv oxidation, pab hauv hluav taws xob conductivity thiab pab ua kom lub neej ntawm kev sib cuag vuam
Dab tsi yog vuam roj vuam siv rau?
Oxy-fuel welding (feem ntau hu ua oxyacetylene vuam, oxyacetylene vuam, lossis roj vuam hauv Teb Chaws Asmeskas) thiab oxy-fuel txiav yog cov txheej txheem uas siv roj gases (los yog kua roj xws li roj av) thiab oxygen rau vuam lossis txiav hlau
Cov iav hauv qab tsav puas muab ntau lub cav fais fab?
Gears hauv qab tsav muab ntau lub cav fais fab. Txoj hauj lwm ib qho ntawm qhov hloov hluav taws xob tso cai rau koj siv cov khoom siv nrog lub cav tawm. Lub teeb liab yuav ib txwm thim rov qab tom qab tig. Thaum siv cov teeb pom kev nruab hnub nruab hnub, cov teeb pom kev tom qab tsis nyob
Hom hlau twg siv rau vuam rooj saum?
A36 steel yog koj qhov yooj yim vaj ntau yam kub dov steel phaj. Cov neeg feem coob hu nws 'mild steel'. Qhov no yeej yog ib qho kev xaiv ntau heev rau lub welding rooj saum. Koj tuaj yeem txuas nws lossis ntsia nws rau txhua txoj kev uas koj nyiam
Dab tsi yog hom vuam fais fab qhov twg?
Muaj tsib hom hluav taws xob muaj nyob: AC transformer; DC rectifier; AC/DC transformer rectifier, DC generator thiab inverter. Hom kev tswj, xws li thawj tapping, saturable reactor, thyristor thiab inverter yog qhov tseem ceeb hauv kev xaiv lub zog
