Yog tias koj txaus siab rau kev siv tshuab hlau, tom qab ntawd kawm coj mus tshawb xyuas raws li nws cov kev faib tawm. Cov hom vuam sib txawv hauv cov lus ntawm lub cev, nyob ntawm daim ntawv siv lub zog siv los ua qhov sib txuas welded. Kawm txog qhov kev xav ntawm peb qib kawm ntawm vuam: thermal, thermomechanical thiab tshuab siv. Txhua ntawm lawv suav nrog cov hom vuam sib txawv, uas tau cais raws li ntau yam ntawm cov yam ntxwv kev ua haujlwm thiab thev naus laus zis.
Cov Lus Qhia

Kev tuav vuam yog ua los ntawm ib tus neeg siv lub cuab yeej. Cov khoom siv vuam vuam tau txais lub zog los ntawm cov khoom siv tshwj xeeb. Piv txwv li, thaum ua haujlwm arc vuam - fusion vuam, cua sov yog kwv los ntawm hluav taws xob arc. Arc vuam yog ua nrog ib qho electrode uas, ua ntej melted thaum vuam, yog li ua raws li tus muab tub lim hlau. Lub tshuab hluav taws xob molten tau nkag mus rau hauv lub pas dej weld yog cov khoom siv ntxiv rau ntawm qhov chaw zom hlau hlau.

Kev tsim kho thiab kev sib dhos tsim khoom yuav siv thawj txoj haujlwm ntawm qhov ntim ntawm arc vuam.
Xaiv cov khoom siv hluav taws xob, cov tub txawj tub ntse tsis nyiam xeb hlau electrode, txho los ntawm xaim, txheej nrog xaum qhuav ua kom yooj yim rau kev sib txuas. Tam sim no, thaum welding, electrodes nrog cov pas nrig ua los ntawm cov hlau yog siv, cov tshuaj lom neeg muaj pes tsawg leeg uas suav nrog cov tshuaj tshwj xeeb. Lub tshuab hluav taws xob yuav tsum tau them nrog cov txheej tshwj xeeb uas muaj cov khoom uas tiv thaiv arc hlau thaum vuam los ntawm cov kev cuam tshuam ntawm ib puag ncig.

Txhawm rau tsim qhov sib txuas welded, tus tswv ntaus ua ke arc ntawm qhov kis ntawm lub neej yav tom ntej seam, melts cov npoo ntawm puag hlau ua ke nrog electrode. Nws yog ib qho tsim nyog los xyuas kom meej tias qhov chaw nruab nrab ntawm qhov chaw yuav tsum tau txuas nrog yog cov kua hlau ntawm cov npoo ntawm qhov loj thiab electrode. Tus kws kho hluav taws xob ua tiav cov hlau sib tov hauv ib da dej, kev tsim ntawm ib leeg ntawm txoj siv. Tom qab ntawd lub tshuab hluav taws xob yuav tsum txav mus los, mus rau ntawm lub nqaws thiab nrog nws, kom muaj kev sib txuas ntawm cov ntu.

Thaum ua haujlwm submerged arc vuam, nco ntsoov tias arc hlawv rau hauv qab lub pob ntawm vuam flux. Vuam yuav tsum ua nrog cov khoom siv vuam tshuab. Ua ntej, lub arc zoo siab heev. Tom qab ntawd cov xaim electrode los yog muab tub lim hlau ua kom haum. Hauv qhov no, kev hloov tus txheeb ze ntawm arc thiab cov khoom welded yog nqa los ntawm cov tshuab tsis muaj tib neeg koom nrog. Tus kws ntsa dej nkag rau hauv qhov kev pabcuam tsim nyog. Qhov vuam arc melts cov khoom tseem ceeb, hlau thiab flux. Cov txheej txheem txuas ntxiv mus kom txog rau thaum qhov tsim ntawm lub pas dej weld them nrog ib txheej ntawm molten flux. Thaum arc hlawv nyob rau hauv flux, nws yog kev tiv thaiv kev tiv thaiv los ntawm kev puas tsuaj ntawm huab cua.
