TIG (Tungsten Inert Gas Vuam) thiab MIG (Hlau Inert Gas Vuam) yog ob txoj kev siv arc vuam, uas sib txawv ntawm cov electrode, shielding gas, hom kev ua haujlwm, vuam zoo, thiab cov ntaub ntawv siv tau. Peb yuav piav qhia qhov txawv ntawm ntau qhov kev pom hauv qab no.
Cov lus sib piv luv luv
| yam khoom | TIG welding | MIG vuam |
|---|---|---|
| Hluav taws xob | Tsis yog -consumable tungsten electrode + phau ntawv xaim filling | Consumable welding hlau (tsis siv neeg hlau pub) |
| Tiv thaiv roj | Ntshiab inert gases (Ar, Nws) | Inert gas lossis roj sib tov (Ar + CO₂, thiab lwm yam) |
| Kev ua haujlwm nyuaj | Siab (kev sib koom tes, kev txawj ntse) | Tsawg nyuaj (yooj yim siv nrog ib txhais tes) |
| Vuam ceev | qeeb | ceev |
| Weld tsos | Aesthetically pleasing thiab txaws -dawb | Tej zaum yuav muaj txaws; yuav tsum tau ntxuav. |
| Cov ntaub ntawv siv tau | Cov ntawv nyias nyias, tsis yog - hlau ferrous, stainless hlau | Cov phaj nruab nrab thiab hnyav, carbon hlau, aluminium, stainless hlau |
| Cov ntawv thov tseem ceeb | Precision qhov chaw, kav dej, aerospace | Tsheb, kev tsim kho, tshuab hnyav |
1. Electrode thiab Filler Khoom
TIG: Siv cov khoom siv tsis yog -tungsten electrode; muab tub lim yuav tsum tau muab ntxiv thaum vuam (tes- pub). Lub tungsten electrode nws tus kheej tsis yaj; nws tsuas yog ua haujlwm los tswj lub arc.
MIG: Siv cov khoom siv hlau uas siv tau los ua ob qho khoom siv electrode thiab muab tub lim. Cov hlau yog txiav thiab tsis tu ncua pub rau hauv lub pas dej molten ntawm lub vuam teeb.
2. Tiv thaiv roj
TIG: Feem ntau siv cov roj ntshiab inert (xws li argon lossis helium) kom tsis txhob muaj cov kab mob sib kis los ntawm cov roj reactive xws li oxygen.
MIG: tuaj yeem siv cov pa roj ntshiab (rau vuam aluminium, stainless hlau, thiab lwm yam) los yog sib xyaw ntawm cov roj (xws li Ar + CO₂, rau carbon steel). Cov khoom xyaw nquag hauv qhov sib tov tuaj yeem txhim kho arc stability.
3. Kev ua haujlwm nyuaj thiab kev txawj ntse
TIG: Yuav tsum muaj ob- tes sib koom tes- ib txhais tes tuav lub vuam teeb, thiab lwm txhais tes pub cov xaim xaim rau hauv lub pas dej ua ke. Nws xav tau qib siab ntawm tes- qhov muag kev sib koom tes thiab kev tswj xyuas tam sim no los ntawm tus welder, ua rau muaj kev kawm nkhaus.
MIG: Yooj yim rau kev khiav lag luam; tsuas yog ib txhais tes tuav lub vuam teeb, thiab cov xaim muab tub lim yog cia li pub rau hauv. Haum rau cov pib tshiab thiab ib nrab- tsis siv neeg / tsis siv neeg ntau lawm.
4. Vuam ceev thiab ua haujlwm tau zoo
TIG: welding qeeb qeeb vim nws yuav tsum tau ntxiv cov khoom siv hlau los ntawm qhov taw tes thiab kev tswj xyuas meej ntawm cov khoom siv hluav taws xob, tsim nyog rau cov khoom me me, me me -batch, lossis kho ua haujlwm.
MIG: welding ceev; Kev noj cov hlau tsis tu ncua ua rau muaj kev ua haujlwm siab, tsim nyog rau nruab nrab - cov phaj tuab, welds ntev, thiab ntau lawm.
5. Weld Zoo thiab tsos
TIG: Aesthetically pleasing welds tsis muaj spatter thiab zoo heev airtightness, ua tshwj xeeb tshaj yog haum rau precision workpieces yuav tsum tau zoo nyob rau hauv ob qho tib si tsos thiab sab hauv.
MIG: Lub zog weld siab, tab sis tuaj yeem ua rau tawg thiab slag, yuav tsum tau ntxuav tom qab; nws cov tsos precision feem ntau qis dua TIG.
6. Cov khoom siv thiab Thicknesses
TIG: Tshwj xeeb tshaj yog haum rau nyias daim hlau (0.5 hli thiab siab dua) thiab tsis yog - ferrous hlau (aluminium, magnesium, titanium, tooj liab, thiab lwm yam), nrog rau stainless hlau thiab siab - kub alloys.
MIG: Ntau dua haum rau nruab nrab- cov phaj tuab (2 hli thiab siab dua) ua los ntawm qis- carbon steel, qis- alloy steel, aluminium, stainless hlau, thiab lwm yam, nrog rau kev ua tau zoo tshwj xeeb hauv cov khoom tuab.
7. Cov xwm txheej ntawm daim ntawv thov
TIG: Aerospace, cov khoom siv kho mob, cov khoom siv ua zaub mov, cov yeeb nkab vuam, cov cuab yeej precision, thiab cov hlau tsis sib xws.
MIG: Automotive manufacturing, steel qauv tsim, shipbuilding, hnyav machinery, thawv manufacturing, thiab lwm yam lag luam uas yuav tsum tau high efficiency.
