Vuam teeb meem qee zaum ntsib thaum lub sij hawm installation ntawm carbon steel hlab. Yog li, yuav ua li cas weld tubes? Peb yuav tsum xyuam xim rau dab tsi thaum welding carbon steel hlab?

1. Gas vuam
Gas vuam siv tau rau vuam, uas yog sib tov cov roj combustible thiab combustion-txhawb roj ua ke, siv nws ua lub tshav kub ntawm cov nplaim taws, thiab ces yaj thiab welding cov kav dej ua ke.

2. Arc vuam

Arc welding kuj siv tau, uas yog, arc vuam siv raws li txoj kev vuam. Ib lub tshav kub uas txuas cov kav dej ua ke. Txoj kev vuam no feem ntau siv hauv kev tsim khoom. Ntxiv rau ob txoj hauv kev saum toj no, cov kav dej welded tseem tuaj yeem siv kev sib cuag vuam, thiab cov txheej txheem tshwj xeeb yuav tsum tau welded nyob ntawm cov khoom thiab cov kev xav tau ntawm cov kav dej.

Cov hlau muaj hlau thiab carbon nrog me me ntawm lwm yam hlau, xws li manganese, chromium, silicon, vanadium, thiab nickel. Tsawg carbon steel tsuas muaj 0.3 feem pua ​​carbon, ua rau nws yooj yim heev rau welding.
Cov pa roj carbon nruab nrab muaj 0.30 txog 0.60 feem pua ​​carbon, thiab cov pa roj carbon siab ntawm 0.61 txog 2.1 feem pua ​​carbon. Los ntawm kev sib piv, cam khwb cia hlau muaj txog li 3 feem pua ​​carbon, uas ua rau nws nyuaj heev rau welding.

Carbon steel tube welding ceev faj:

1. Ua ntej lub raj xa dej yog welded, nws yog ib qho tsim nyog yuav tsum tshem tawm tag nrho cov khib nyiab hauv cov yeeb nkab. Tom qab kev tsim kho tiav lawm, ib lub phaj thaiv tuaj yeem siv los kaw nws kom tsis txhob muaj cov khib nyiab poob rau hauv nws. Nyob rau tib lub sijhawm, ua ntej vuam, nws yog qhov tsim nyog los txhuam cov roj stains ntawm lub nozzle kom txog rau thaum cov hlau zoo li luster tshwm.

2. Feem ntau hais lus, cov khoom siv yeeb nkab yog qhov pib kauv welded yeeb nkab, yog li txoj kev vuam ntawm phau ntawv arc tuaj yeem xaiv tau. Rau cov yeeb nkab zoo li no, tag nrho cov welds yuav tsum tau muab tso rau hauv qab ntawm argon arc vuam, thiab lub hau yuav tsum tau sau nrog phau ntawv arc vuam.
