Submerged arc steel yeeb nkab tau dhau los ua cov yeeb nkab steel ntawm cov roj av loj thiab cov tsheb thauj mus los hauv tsev thiab txawv teb chaws vim nws cov phab ntsa loj, cov khoom siv zoo thiab kev ua haujlwm ruaj khov. Nyob rau hauv qhov loj-diameter submerged arc steel yeeb nkab welded pob qij txha, weld seam thiab tshav kub-tshem tawm tsam yog qhov chaw uas muaj ntau yam tsis xws luag, thaum vuam undercuts, pores, slag inclusions, tsis txaus fusion, incomplete penetration, weld pob, hlawv-los ntawm. , thiab vuam kab nrib pleb Nws yog daim ntawv tseem ceeb ntawm vuam tsis xws luag, thiab nws feem ntau yog lub hauv paus chiv keeb ntawm kev raug mob ntawm submerged arc steel yeeb nkab. Cov kev tswj xyuas yog raws li nram no:

1. Tswj ua ntej vuam:

1) Cov khoom siv raw yuav tsum tau kuaj xyuas ua ntej, thiab tsuas yog tom qab dhau qhov kev tshuaj xyuas lawv tuaj yeem nkag mus rau qhov chaw tsim kho, thiab txiav txim siab siv cov hlau tsis tsim nyog.
2) Qhov thib ob yog kev tswj cov khoom siv vuam. Tshawb xyuas seb cov khoom siv vuam puas yog cov khoom tsim nyog, seb qhov chaw cia thiab qhov cub puas tau siv, seb qhov chaw ntawm cov khoom siv vuam yog huv si thiab tsis muaj xeb, seb cov txheej ntawm cov vuam pas puas puas thiab seb puas muaj pwm.
3) Qhov thib peb yog kev tswj kom huv ntawm qhov chaw vuam. Tshawb xyuas qhov huv ntawm qhov chaw vuam, thiab yuav tsum tsis txhob muaj cov av xws li dej, roj, xeb thiab oxide zaj duab xis, uas ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev puas tsuaj sab nraud hauv qhov vuam.
4) Txhawm rau xaiv txoj kev vuam tsim nyog, lub hauv paus ntsiab lus ntawm kev sim vuam thawj zaug thiab tom qab vuam yuav tsum tau ua.

2. Tswj thaum vuam:

1) Txheeb xyuas seb qhov tshwj xeeb ntawm vuam hlau thiab flux puas yog raws li cov txheej txheem vuam txheej txheem los tiv thaiv kev siv vuam hlau tsis raug thiab flux thiab ua rau vuam raug mob.
2) Saib xyuas qhov chaw vuam. Thaum qhov chaw vuam tsis zoo (qhov ntsuas kub qis dua 0 ℃, qhov txheeb ze av noo siab dua 90%), kev ntsuas yuav tsum tau ua ua ntej vuam.
3) Ua ntej vuam ua ntej, xyuas qhov zawj qhov ntev, nrog rau qhov khoob, cov npoo ntsej muag, cov kaum sab xis thiab qhov tsis zoo, seb lawv puas ua tau raws li cov txheej txheem.
4) Seb qhov vuam tam sim no, vuam voltage, vuam ceev thiab lwm yam txheej txheem tsis xaiv nyob rau hauv cov txheej txheem tsis siv neeg submerged arc vuam yog raug.
5) Saib xyuas cov neeg ua haujlwm vuam kom siv tau tag nrho ntawm qhov ntev ntawm cov pilot arc phaj kawg ntawm cov yeeb nkab steel thaum lub sij hawm tsis siv neeg submerged arc vuam, thiab ntxiv dag zog rau kev siv ntawm cov pilot arc phaj nyob rau hauv thiab sab nraud vuam, uas yuav pab tau. txhim kho cov yeeb nkab kawg welding.
6) Saib xyuas seb cov neeg ua haujlwm vuam ua ntej ntxuav cov slag thaum kho vuam, seb cov pob qij txha puas tau ua tiav, seb puas muaj roj, xeb, slag, dej, xim thiab lwm yam av ntawm qhov zawj.
