Yog tias koj txaus siab rau TIG vuam, kos tawm:How to Weld (TIG).

Kauj Ruam 1: Keeb kwm

MIG welding tau tsim nyob rau xyoo 1940's thiab 60 xyoo tom qab lub hauv paus ntsiab lus tseem ceeb heev.MIG vuam siv lub arc ntawm hluav taws xob los tsim ib tug luv luv Circuit Court ntawm ib tug tsis tu ncua pub anode (+ cov hlau-fed vuam phom) thiab ib tug cathode (- cov hlau yog welded).

Lub tshav kub uas tsim los ntawm luv luv Circuit Court, nrog rau ib tug non-reactive (li no inert) gas nyob rau hauv melts cov hlau thiab tso cai rau lawv sib tov ua ke.Thaum lub tshav kub raug tshem tawm, cov hlau pib txias thiab khov, thiab tsim ib daim tshiab ntawm fused hlau.

Ob peb xyoos dhau los lub npe tag nrho - Hlau Inert Gas (MIG) welding tau hloov mus rau Gas Metal Arc Vuam (GMAW) tab sis yog tias koj hu nws tias cov neeg feem coob yuav tsis paub qhov heck koj tham txog - lub npe MIG welding muaj tseeb. daig.

MIG vuam yog qhov tseem ceeb vim tias koj tuaj yeem siv nws los vuam ntau hom hlau: carbon hlau, stainless hlau, txhuas, magnesium, tooj liab, npib tsib xee, silicon bronze thiab lwm yam alloys.

Nov yog qee qhov zoo rau MIG vuam:

• Muaj peev xwm koom nrog ntau yam hlau thiab thicknesses
• Txhua txoj haujlwm vuam muaj peev xwm
• Ib tug zoo weld hlaws
• Tsawg kawg ntawm weld splatter
• Yooj yim kawm

Nov yog qee qhov tsis zoo ntawm MIG vuam:

• MIG vuam tsuas yog siv rau ntawm nyias mus rau nruab nrab tuab hlau
• Kev siv cov roj inert ua rau hom vuam no tsis yooj yim dua li arc vuam uas yuav tsum tsis muaj cov khoom siv hluav taws xob sab nraud.
• Ua ib qho me ntsis sloppier thiab tsawg tswj vuam piv rau TIG (Tungsten Inert Gas Vuam)

Kauj Ruam 2: Lub tshuab ua haujlwm li cas

MIG welder muaj ob peb qhov sib txawv.Yog tias koj qhib ib qho koj yuav pom qee yam uas zoo li cov duab hauv qab no.

Tus Welder

Nyob rau hauv lub welder koj yuav pom ib tug spool ntawm hlau thiab ib tug series ntawm rollers uas thawb cov hlau tawm mus rau vuam phom.Tsis muaj dab tsi tshwm sim hauv qhov no ntawm cov welder, yog li nws tsim nyog siv sijhawm ib feeb thiab paub koj tus kheej nrog rau qhov sib txawv.Yog tias cov xaim pub jams rau ib qho laj thawj (qhov no tshwm sim ib ntus) koj yuav xav xyuas qhov no ntawm lub tshuab tawm.

Qhov loj spool ntawm hlau yuav tsum tuav nrog ib tug nro txiv ntseej.Cov txiv ntseej yuav tsum nruj txaus kom cov spool los ntawm unraveling, tab sis tsis yog nruj heev uas lub rollers tsis tuaj yeem rub cov hlau los ntawm lub spool.

Yog tias koj ua raws li cov xaim los ntawm cov spool koj tuaj yeem pom tias nws nkag mus rau hauv ib txheej ntawm cov yob uas rub cov hlau tawm ntawm lub yob loj.Qhov no welder yog teem rau weld aluminium, yog li nws muaj txhuas hlau loaded rau hauv nws.MIG welding kuv yuav piav qhia hauv no yog rau cov hlau uas siv tooj liab xim hlau.

Lub Roj Tank

Piv txwv tias koj tab tom siv cov roj tiv thaiv nrog koj tus MIG welder yuav muaj lub tank roj tom qab MIG.Lub tank yog 100% Argon lossis sib xyaw ntawm CO2 thiab Argon.Cov roj no tiv thaiv cov vuam thaum nws tsim.Yog tsis muaj roj koj cov welds yuav zoo li xim av, splattered thiab tsuas yog feem ntau tsis zoo heev.Qhib lub ntsiab valve ntawm lub tank thiab xyuas kom meej tias muaj qee cov roj hauv lub tank.Koj qhov ntsuas yuav tsum tau nyeem ntawm 0 txog 2500 PSI hauv lub tank thiab tus tswj hwm yuav tsum tau teeb tsa ntawm 15 thiab 25 PSI nyob ntawm seb koj nyiam teeb khoom li cas thiab hom phom vuam uas koj siv.

** Nws yog ib txoj cai zoo ntawm tus ntiv tes xoo qhib txhua lub li qub rau txhua lub tank roj hauv lub khw tsuas yog ib nrab tig los yog li ntawd.Qhib lub valve txhua txoj kev tsis txhim kho koj cov dej ntws ntau dua li tsuas yog tawg lub valve qhib vim lub tank nyob rau hauv siab heev.Lub logic tom qab no yog li ntawd yog tias ib tug neeg xav tau ceev ceev kaw cov pa thaum muaj xwm txheej ceev lawv tsis tas yuav siv sij hawm cranking down lub siab qhib valve.Qhov no yuav tsis zoo li qhov teeb meem loj heev nrog Argon lossis CO2, tab sis thaum koj ua haujlwm nrog cov pa taws xws li oxygen lossis acetylene koj tuaj yeem pom yog vim li cas nws tuaj yeem siv tau thaum muaj xwm txheej ceev.**

Thaum cov hlau hla dhau ntawm cov chais nws raug xa mus rau ib txheej ntawm cov hoses uas ua rau cov phom vuam.Cov hoses nqa cov electrode thiab cov roj argon.

Vuam Phom

Cov phom vuam yog qhov kawg ntawm kev lag luam.Nws yog qhov uas feem ntau ntawm koj cov xim yuav raug coj mus rau lub sijhawm vuam txheej txheem.Cov phom muaj ib tug txhais tau tias tswj cov xaim pub thiab ntws ntawm hluav taws xob.Cov hlau yog coj los ntawm kev hloov pauv tooj liab taub uas yog tsim rau txhua tus welder tshwj xeeb.Cov tswv yim sib txawv hauv qhov loj kom haum txawm tias txoj kab uas hla uas koj tau tshwm sim rau vuam nrog.Feem ntau qhov no ntawm cov welder yuav tau teeb tsa rau koj.Sab nraud ntawm qhov kawg ntawm rab phom yog npog los ntawm ceramic lossis hlau khob uas tiv thaiv cov electrode thiab coj cov roj ntws tawm ntawm qhov kawg ntawm rab phom.Koj tuaj yeem pom qhov me me ntawm cov hlau nplaum tawm ntawm qhov kawg ntawm rab phom vuam hauv cov duab hauv qab no.

Av Clamp

Lub hauv av clamp yog lub cathode (-) nyob rau hauv Circuit Court thiab ua kom tiav lub Circuit Court ntawm lub vuam, vuam phom thiab qhov project.Nws yuav tsum tau txiav ncaj qha mus rau daim hlau ua vuam los yog mus rau lub rooj vuam hlau zoo li ib daim duab hauv qab no (peb muaj ob lub vuam vuam vim li no ob lub clamps, koj tsuas yog xav tau ib lub clamp los ntawm cov vuam txuas rau koj daim rau vuam).

Cov clip yuav tsum tau ua kom zoo sib cuag nrog cov khoom welded rau nws ua hauj lwm yog li nco ntsoov zom cov xeb los yog xim uas yuav tiv thaiv nws los ntawm kev sib txuas nrog koj cov hauj lwm.
