Copper tube welding txoj kev?

Qhov vuam ntawmcev toojyeej ib txwm yog ib qho tseem ceeb ntawm kev tsim khoom thiab siv cov raj tooj liab.Thaum lub sijhawm ua haujlwm niaj hnub zoo li no, ntau yam teeb meem me feem ntau tshwm sim.Yuav ua li cas peb weld lub raj tooj liab, ib kauj ruam yooj yim yog qhia ntawm no hnub no.

(1) Kev npaj ua ntej

Ua ntej vuam, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab txog cov khoom siv vuam, cov cuab yeej vuam, thiab cov khoom yuav tsum tau ua.Nws yog ib qho tsim nyog los xyuas seb cov roj sib txuas hauv lub tog raj kheej oxygen thiab lub tog raj kheej thib ob puas txaus, kev tshuaj xyuas ua ntej ntawm txhua yam tsis zoo, thiab cov khoom ntawm cov khoom yog polished huv si, thiab lwm yam, cov no yog cov txheej txheem ua ntej. kev npaj

(2) Vuam

Thaum vuam, nws yog ib qho tsim nyog yuav tsum tau preheat lub raj tooj liab, ua kom sov qhov chaw uas lub raj tooj liab yuav tsum tau welded nrog nplaim taws, thiab saib cov xim.Feem ntau, liab tsaus yog li 600 degrees Celsius, sib sib zog nqus liab yog li 700 degrees Celsius, thiab txiv kab ntxwv yog li 1000 degrees Celsius.

Thaum lub sij hawm vuam txheej txheem, cov khoom puas raug tiv thaiv.Feem ntau, lub solenoid valve, plaub-txoj kev valve, thiab lwm yam yuav tsum tau disassembled thiab ces welded rau zaum ob.Cov nplaim hluav taws tsis tuaj yeem siv los ua hluav taws xob hluav taws xob.Thaum lub sij hawm vuam txheej txheem, vuam yuav tsum tau ua kom tiav sai thiab meej, zoo dua nyob rau hauv ib lub sij hawm.Thaum lub vuam yuav xaus rau annealing, qhov kub yog tswj ntawm li 300 degrees

(3) Tom qab vuam

Tom qab vuam tiav lawm, nws yuav tsum tau txias rau ib lub sijhawm, thiab cov oxide, plua plav thiab qee qhov vuam slag hauv lub raj tooj liab yuav tsum tau ntxuav nrog cov nitrogen qhuav, thiab qee qhov chaw vuam yuav tsum tau kho.Ua ntej kho qhov vuam, cov oxide txheej ntawm qhov chaw yuav tsum tau muab tshem tawm.Tom qab kho qhov vuam, qhov oxidized tseem yuav tsum tau kho, thiab tom qab ua tiav, nws tseem raug kho nrog cua tshuab kom cov phab ntsa sab hauv ntawm lub raj tooj liab qhuav thiab cov phab ntsa sab nrauv tsis zoo.
