Vuam yog ib txoj kev koom mus tas li los ntawm fusion, nrog lossis tsis siv cov hlau muab tub lim. Nws yog ib qho tseem ceeb fabrication txheej txheem. Vuam muab faib ua ob pawg.
Fusion welding - Hauv fusion vuam, cov hlau tau koom ua ke yog melted thiab fuses ua ke los ntawm cov khoom tom qab ntawm cov hlau molten. Yog hais tias tsim nyog, ib tug molten muab tub lim yog ntxiv.
Piv txwv li, Gas welding, arc vuam, thermite welding.
Pressure welding- Cov hlau tau koom ua ke tsis tau yaj, kev sib koom ua ke ntawm cov hlau tau los ntawm kev siv lub siab ntawm vuam kub.
Piv txwv li, Resistance welding, forge welding.
Qhov zoo ntawm vuam
1.Welded sib koom ua ke muaj lub zog siab, qee zaum ntau dua li cov niam txiv hlau.
2. Cov khoom sib txawv tuaj yeem welded.
3.Welding tuaj yeem ua txhua qhov chaw, tsis xav tau kev tshem tawm txaus.
4.Lawv muab cov tsos du thiab simplicity hauv kev tsim.
5.Lawv tuaj yeem ua tau raws li cov duab thiab txhua qhov kev taw qhia.
6.Nws tuaj yeem ua haujlwm.
7.Muab ib qho kev sib koom ua tiav.
8.Ntxiv thiab hloov kho cov qauv uas twb muaj lawm yog ib qho yooj yim.
Disadvantage ntawm vuam
1.Cov tswv cuab tuaj yeem hloov pauv vim qhov tsis sib xws ntawm cov cua sov thiab cua txias thaum vuam.
2.Lawv yog cov sib koom ua ke mus tas li, kom dismantle peb yuav tsum tau tawg lub vuam.
3.High thawj peev
