Kev nkag siab txog qee cov tswv yim tsim nyog rau MIG vuam tuaj yeem pab cov vuam vuam tau zoo weld zoo thiab zam qhov kev ntxhov siab thiab cov nqi rov ua dua. Txhua yam los ntawm qhov chaw zoo ntawm MIG welding phom mus rau lub kaum sab xis thiab kev mus ncig ceev tuaj yeem ua rau muaj kev cuam tshuam.
Xav txog plaub txoj kev pom zoo no:
1. txhais tes kom khov kho nws thiab ua kom lawv ntawm lossis qis dua lub luj tshib qhov siab. Txoj hauv kev no tsis tsuas yog ua kom yooj yim rau kev ua kom zoo dua qub, tab sis nws kuj pab txhim kho ergonomics. Qhov ntawd yog qhov tseem ceeb tshwj xeeb rau cov welding welding rau lub sijhawm ntev, yog li lawv tuaj yeem zam kev raug mob.
2.Welders yuav tsum khaws qhov kev sib cuag-ntsib-rau-ua haujlwm nrug (CTWD) ntawm kwv yees li 3/8 mus rau 1/2 nti rau luv-circuit vuam thiab ib ncig ntawm 3/4 nti rau cov tshuaj tsuag hloov MIG vuam.
3.Siv lub kaum sab xis mus ncig kom zoo. Thaum thawb vuam, welders yuav tsum tuav rab phom ntawm lub kaum sab xis 10-degree. Cov txheej txheem no tsim cov hlaws dav nrog kev sib koom ua ke tsawg dua. Rau cov txheej txheem rub, welders siv tib lub kaum sab xis, rub rab phom mus rau lawv lub cev. Qhov no ua rau kom nkag tau ntau dua thiab nqaim weld hlaws.
4.Ua kom muaj kev sib tw khiav ceev nrog cov xaim ntawm cov ntug ntawm lub pas dej ua ke. Kev nrawm dhau ntawm kev mus los ua rau cov hlaws nqaim uas yuav tsis tuaj yeem khi rau ntawm cov ntiv taw weld thiab yuav tsis muaj kev nkag mus zoo. Kev mus ncig qeeb dhau ua rau muaj qhov dav dav, kuj nrog kev nkag mus tsis txaus. Ob qho tib si qeeb thiab nrawm dhau mus nrawm tuaj yeem ua rau hlawv-los ntawm cov hlau nyias nyias.
Raws li nrog rau cov txheej txheem vuam, kev xyaum yog ib feem loj ntawm MIG vuam kev vam meej. Nrog rau cov txheej txheem zoo, nws tseem ceeb heev uas yuav tsum tau npaj thiab ntxuav cov khoom siv hauv paus ua ntej vuam thiab tswj MIG vuam phom thiab cov khoom siv tau zoo. Qhov no tuaj yeem txo qis sijhawm los daws cov teeb meem khoom siv lossis teeb meem kev sib tsoo thiab cov teeb meem xws li kev noj cov hlau tsis zoo.
