Loj Diameter LSAW yeeb nkab phab ntsa tuab nrog nws cov loj, cov khoom siv zoo, cov txheej txheem ruaj khov, ua thawj qhov kev xaiv rau loj hauv tsev thiab txawv teb chaws cov roj thiab roj yeeb nkab project. Nyob rau hauv qhov loj-ncaj seam submerged arc welded yeeb nkab welded pob qij txha, weld thiab tshav kub cuam tshuam cheeb tsam yog feem ntau yuav tsim ib tug ntau yam ntawm imperfections welded undercut, porosity, slag, tsis muaj fusion, tsis muaj kev nkag mus, weld, hlawv vuam tawg yog cov daim ntawv tseem ceeb ntawm vuam tsis xws luag, thiab feem ntau yog lub hauv paus ntawm thiaj li ncaj seam submerged arc welded yeeb nkab zoo raug xwm txheej.
Kev ntsuas kev tswj xyuas zoo: 1, ua ntej vuam zoo tswj 1) Ua ntej, ua kom zoo ntawm cov khoom siv raw, tom qab dhau kev tshuaj xyuas ua ntej nkag mus rau hauv qhov chaw tsim kho, thiab txiav txim siab xaus rau kev siv cov hlau tsis zoo 2) ua raws li cov. kev tswj cov khoom siv vuam. Xyuas seb cov khoom siv vuam rau cov khoom tsim nyog, kev cia khoom thiab ci qhov system puas yuav ua tau, seb puas yuav muab qhov vuam qhov chaw huv si thiab tsis muaj xeb, electrode txheej tsis zoo, nrog lossis tsis muaj pwm. 3) Ib zaug ntxiv, huv si weld cheeb tsam tswj. Kev tu QA weld cheeb tsam, tsis muaj dej, roj, xeb thiab av oxide zaj duab xis, uas yog los tiv thaiv sab nraud weld defects ua lub luag haujlwm tseem ceeb. 4) Xaiv txoj kev vuam tsim nyog yuav tsum tau ua thawj zaug kev xeem vuam, tom qab vuam cov ntsiab lus. 2, welding zoo tswj 1) raws li cov txheej txheem vuam specifications hlau thiab flux tshuaj xyuas yog lawm, los tiv thaiv kev siv tsis raug ntawm vuam hlau thiab flux tshwm sim los ntawm qhov zoo ntawm qhov kev huam yuaj. 2) txhawm rau saib xyuas qhov chaw vuam, siv cov kev ntsuas tsim nyog tom qab vuam thaum vuam ib puag ncig tsis zoo (kub qis dua 0 ℃, qhov txheeb ze av noo ntau dua 90%) yuav tsum yog. 3) ua ntej qhov kev xav tau thawj qhov kev ntsuas vuam zawj qhov ntev, suav nrog qhov chaw, qhov tsis pom ntawm ntug, thiab seb lub kaum sab xis thiab qhov chaw nres nkoj tsis raug raws li qhov yuav tsum tau ua. 4) nyob rau hauv lub submerged arc vuam txheej txheem sab hauv thiab sab nraud cov xaiv vuam tam sim no, vuam voltage, vuam ceev thiab lwm yam tsis yog lawm. 5) Kev saib xyuas ntawm cov neeg ua haujlwm nyob rau hauv submerged arc vuam sab hauv thiab sab nraud welded steel yeeb nkab tag nrho kom zoo dua ntawm qhov kawg phaj arc ntev, ntxiv dag zog rau kev ua haujlwm ntawm vuam arc thaum cov phaj sab hauv thiab sab nrauv, uas pab txhim kho qhov zoo ntawm vuam cov yeeb nkab kawg. . 6) Kev saib xyuas ntawm cov neeg ua haujlwm hauv cov vuam slag vuam seb lawv puas tau ntxuav ua ntej, txawm tias koj tau ua tiav kev sib koom ua ke ntawm seb puas muaj roj, xeb, slag, dej, xim thiab lwm yam khoom paug.
