Hauv kev lag luam vuam, muaj ntau yamhom vuam. Arc welding thiab qhov chaw vuam yog cov txheej txheem ntau tshaj plaws. Lawv feem ntau siv nyob rau hauv ntau qhov chaw thiab ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam. Raws li ib tug beginner, nws yuav nyuaj rau to taub qhov txawv. Yog tias koj xav kawm txog qhov txawv ntawm arc welding thiab qhov chaw vuam, cov kab lus hauv qab no yuav piav qhia kom ntxaws.

Arc Welding yog dab tsi?

Arc vuamyog cov txheej txheem uas siv cov cua sov uas tsim los ntawm cov hluav taws xob arc kom yaj thiab koom nrog cov hlau ua ke. Lub zog hluav taws xob rau arc vuam tuaj yeem muab tau ncaj qha tam sim no (DC) lossis hloov tam sim no (AC). Raws li cov kev xav tau ntawm vuam, arc vuam siv tau los yog tsis siv cov electrodes. Tsim nyob rau hauv lub xyoo pua puv 19, arc vuam tau ua lub luag haujlwm tseem ceeb hauv kev tsim cov nkoj thiab kuj tau siv dav hauv kev lag luam tsheb thiab kev lag luam hnyav.

Spot Welding yog dab tsi?

Spot welding yog ib daim ntawv ntawmtsis kam vuamuas siv hluav taws xob tam sim no los ua kom muaj cua sov thiab siv lub zog, ua rau cov ntsiab lus sib txuas ntawm cov khoom ua haujlwm los ua ib qho kev sib txuas los yog lub xeev yas thiab koom ua ke. Nws yog ib txoj kev vuam tsoos uas feem ntau siv tooj liab electrodes los ua hluav taws xob. Cov hluav taws xob tam sim no dhau los ntawm cov khoom ua haujlwm, yaj lawv ntawm cov ntsiab lus sib cuag, thiab thaum lub sijhawm tam sim no nres, lub siab tseem tuav cov ntsiab lus sib txuas ua ke, sib koom ua ke.

Qhov txawv ntawm Arc Vuam thiab Spot Welding

Txoj Cai ntawm Vuam

Arc welding thiab qhov chaw vuam ua haujlwm ntawm cov qauv sib txawv. Arc vuam siv cov electrode thiab cov khoom ua haujlwm los tsim cov hluav taws xob arc, ua kom sov. Qhov kub kub melts cov electrode rau hauv cov kua uas ua rau cov hlau sib koom ua ke thiab txias los ua ib qho kev sib txuas, koom nrog ob qhov hlau. Qhov no yog ib hom kua-lub xeev vuam.

Spot welding, ntawm qhov tod tes, koom nrog ob lub workpieces thiab siv lub siab nrog ob lub electrodes. Hluav taws xob tam sim no heats cov ntsiab lus sib cuag ntawm cov electrodes thiab cov workpieces, ua rau lawv yaj. Thaum txias, cov khoom sib txuas ua ke, ua rau nws muaj kev sib txuas ruaj khov.

Kev xav tau ntawm Cov Khoom Siv Filler

Nyob rau hauv cov txheej txheem welding, arc vuam siv tau cov hlau los yog tsis. Thaum vuam ob lub workpieces ua ke, cov khoom muab tub lim yuav tsis xav tau. Spot vuam tsis xav tau cov khoom muab tub lim; nws ncaj qha heats lub workpieces mus rau ib lub xeev yas los koom lawv.

Daim ntawv thov Scope

Spot welding thiab arc vuam muaj qhov sib txawv. Arc welding yog tsim rau vuam complex duab thiab loj hlau workpieces, ua rau nws zoo tagnrho rau kev kho thiab tswj cov khoom loj thiab kev lag luam hnyav. Spot welding feem ntau yog siv rau qhov me me txog 3 millimeters tuab thiab zoo dua rau cov khoom siv vuam ntau. Nws yog feem ntau siv hauv kev lag luam tsheb thiab khoom siv hauv tsev.

Lub sijhawm vuam

Arc welding hlau siv sijhawm ntev dua thiab tsis yog txheej txheem ib zaug. Spot vuam yog nrawm dua thiab tuaj yeem ua tiav cov khoom hauv ib feeb lossis ob peb feeb.

Vuam Nqi

Arc welding muaj tus nqi qis dua, tab sis vim nws txoj kev nyuaj, tus nqi zog rau cov kws tshaj lij arc vuam yog siab. Spot welding muaj tus nqi ntau dua, nrog rau ib qhoqhov chaw vuam tshuabraug nqi ntau npaum li ob peb lub tshuab arc vuam. Txawm li cas los xij, tus nqi ua haujlwm rau cov neeg ua haujlwm yog tsawg, uas tuaj yeem txuag tau cov nqi hauv lub sijhawm ntev.

Kev xav tau ntawm Sab Nraud Siab

Rau cov kev xav tau sab nraud, arc vuam feem ntau tsis xav tau sab nraud. Lub arc generated los ntawm lub hwj chim qhov chaw melts lub workpiece thiab muab tub lim khoom. Spot welding, txawm li cas los xij, yuav tsum muaj huab cua siab los nias ob lub workpieces ua ke, thiab tom qab ntawd cua sov yog tsim los ntawm qhov tam sim no.

Kev nyab xeeb ua haujlwm

Arc vuam yog technically nyuaj thiab yuav tsum tau welding txawj. Yog tias koj xav siv arc vuam, koj yuav tsum tau txais kev cob qhia kev cob qhia. Spot welding yog yooj yim dua thiab muaj kev nyab xeeb dua, yuav tsum muaj kev txawj tsawg dua. Cov neeg ua haujlwm tsuas yog xav tau kev cob qhia yooj yim los pib.

Cov saum toj no yog qhov sib txawv tseem ceeb ntawm arc vuam thiab qhov chaw vuam. Thaum xaiv ib txoj kev vuam, koj yuav tsum xav txog cov ntsiab lus no. Txawm hais tias xaiv qhov chaw vuam lossis arc vuam feem ntau yog nyob ntawm cov khoom koj xav tau vuam, nws cov khoom siv, thiab cov yam ntxwv. Piv txwv li, yog tias koj xav welding loj stainless hlau yeeb nkab, nws yog qhov zoo tshaj rau xaiv arc vuam vim qhov chaw vuam tsuas yog haum rau me me. Yog li ua ntej xaiv txoj kev vuam, nco ntsoov txheeb xyuas txhua qhov xwm txheej los ntawm ntau qhov kev xav.
