Hlau Inert Gas (MIG) welding thiab Tungsten Inert Gas (TIG) vuam yog ob txoj kev nrov vuam uas yuav tsum tau siv cov roj tiv thaiv los tiv thaiv lub pas dej ua ke los ntawm huab cua paug. Txawm li cas los xij, muaj ib qho kev xav tsis zoo uas Manual Metal Arc (MMA) vuam, tseem hu ua Shielded Hlau Arc Vuam (SMAW), kuj yuav tsum tau siv roj. Hauv daim ntawv no, peb yuav tshawb xyuas seb MMA vuam tshuab xav tau roj rau cov txheej txheem vuam.
Keeb kwm:
MMA welding yog txheej txheem vuam uas siv cov flux-coated electrode los tsim cov arc ntawm cov electrode thiab cov khoom ua haujlwm. Cov txheej txheej flux ntawm cov electrode melts thaum lub sij hawm vuam, tsim kom muaj kev tiv thaiv roj thaiv ib ncig ntawm lub pas dej ua ke. Qhov no gas shield tiv thaiv atmospheric contamination thiab xyuas kom meej ib tug huv thiab muaj zog weld.
Kev sib tham:
Tsis zoo li MIG thiab TIG vuam, MMA vuam tsis tas yuav tsum muaj lub tog raj kheej kheej lossis cov khoom siv roj. Cov txheej txheej flux ntawm cov electrode muab cov roj thaiv kev tsim nyog thaum lub sijhawm vuam txheej txheem. Qhov no ua rau MMA vuam yog tus nqi-zoo thiab ntau yam kev xaiv rau vuam nyob rau hauv ntau qhov chaw, nrog rau sab nraum zoov thiab cua txias qhov chaw uas muaj roj shielding yuav nyuaj rau tswj.
Xaus:
Hauv kev xaus, MMA vuam tshuab tsis xav tau roj rau cov txheej txheem vuam. Lub flux-coated electrodes siv nyob rau hauv MMA vuam muab qhov tsim nyog gas shielding los tiv thaiv lub pas dej weld los ntawm atmospheric paug. Qhov no ua rau MMA vuam txoj kev yooj yim thiab siv tau zoo rau kev siv ntau yam.
