Thaum welding steel kav, koj yuav tsum tau them sai sai rau cov teeb meem hauv qab no:

Ua ntej, ntxuav qhov chaw ntawm cov yeeb nkab steel. Ua ntej welding, xyuas kom meej qhov chaw ntawm cov yeeb nkab steel yog huv si thiab tsis muaj roj, xim, dej, xeb, thiab lwm yam impurities. Cov impurities no tuaj yeem cuam tshuam qhov kev vam meej ntawm vuam thiab tej zaum yuav ua rau muaj teeb meem kev nyab xeeb. Cov cuab yeej xws li kev sib tsoo lub log thiab cov txhuam hlau tuaj yeem siv los ntxuav.

Qhov thib ob, kev hloov kho ntawm bevel. Raws li cov phab ntsa tuab ntawm cov yeeb nkab steel, kho cov duab thiab qhov loj ntawm qhov vuam zawj. Yog tias cov phab ntsa tuab tuab dua, qhov zawj tuaj yeem loj dua me ntsis; yog tias phab ntsa thickness yog thinner, qhov zawj tuaj yeem me dua. Nyob rau tib lub sijhawm, qhov smoothness thiab flatness ntawm qhov zawj yuav tsum tau ua kom zoo dua vuam.

Thib peb, xaiv txoj kev vuam tsim nyog. Xaiv txoj kev vuam tsim nyog raws li cov khoom siv, cov lus qhia tshwj xeeb, thiab cov kev xav tau vuam ntawm cov yeeb nkab steel. Piv txwv li, rau daim hlau nyias los yog cov kav dej ntawm cov hlau tsis tshua muaj cov pa roj carbon monoxide, cov roj tiv thaiv vuam lossis argon arc vuam siv tau; rau cov phaj tuab lossis cov qauv hlau, submerged arc vuam lossis arc vuam siv tau.

Plaub, tswj cov vuam tsis. Vuam tsis muaj xws li vuam tam sim no, voltage, vuam ceev, thiab lwm yam. Cov tsis yuav tsum tau kho raws li cov khoom thiab thickness ntawm cov yeeb nkab steel los xyuas kom meej vuam zoo thiab efficiency.

Thib tsib, xyuam xim rau preheating thiab tom qab vuam kev kho mob. Rau ib co high-carbon steel los yog alloy steel, preheating kev kho mob yuav tsum tau ua ntej welding kom txo vuam kev nyuaj siab thiab tiv thaiv qhov tshwm sim ntawm cov kab nrib pleb. Kev kho tom qab vuam muaj xws li vuam txias, vuam slag tshem tawm, thiab lwm yam.

Thaum kawg, ua raws li cov txheej txheem kev nyab xeeb. Thaum lub sijhawm vuam, yuav tsum tau them nyiaj rau cov txheej txheem kev nyab xeeb, xws li hnav khaub ncaws tiv thaiv, hnab looj tes, thiab qhov ncauj qhov ntswg. Nyob rau tib lub sijhawm, cov khoom siv vuam yuav tsum tau tshuaj xyuas thiab tswj xyuas tsis tu ncua kom ntseeg tau tias nws ua haujlwm li qub.
