Hauv kev lag luam ntawm cov kav dej hlau, ntau yam kev vuam siv tau los ua kom tiav cov kev sib txuas zoo thiab txhim khu kev qha. Ib txoj kev zoo li no yogvuam siv lub kauv submerged arc vuam(SAW), uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov yeeb nkab X42 SSAW. Ua tus thawj coj hauv kev lag luam, Cangzhou Spiral Steel Pipe Group Co., Ltd., paub txog nws lub npe Wuzhou, ua raws li cov qauv thoob ntiaj teb thiab xyuas kom meej tias nws cov khoom (suav nrog X42 spiral submerged arc welded yeeb nkab) ua tau raws li API Spec 5L, ASTM A139, ASTM A252 thiab EN 10219. Hauv cov blog no peb nkag mus rau hauv lub ntiaj teb zoo nkauj ntawm X42 SSAW yeeb nkab, qhia txog qhov zoo ntawm kev siv spiral submerged arc welding hauv kev tsim cov yeeb nkab spirally welded.

Kawm txog Spiral Submerged Arc Welding (SAW):

Kev vuam hlau uas muaj kauv sib txuas, tseem hu ua SAW, yog ib txoj kev vuam tshwj xeeb uas siv los tsim cov kav dej uas muaj kauv sib txuas xws liX42 SSAW yeeb nkabCov txheej txheem no suav nrog kev yaj cov hlau flux thiab cov hlau hauv paus siv cov cua sov tsim los ntawm kev sib xyaw ntawm cov hlau thiab cov flux hauv qab txheej flux. Cov txheej flux ua haujlwm ua ib qho kev tiv thaiv, tiv thaiv cov pa phem hauv huab cua los ntawm kev cuam tshuam rau cov txheej txheem soldering. Txoj kev no muaj ntau qhov zoo dua li lwm cov txheej txheem vuam.

Qhov zoo ntawm kev vuam siv submerged arc welding:

1. Kev vuam zoo sib xws thiab siab: Txoj kev SAW siv rau hauv X42 SSAW yeeb nkab tsim cov vuam zoo sib xws thiab siab. Thaum lub arc raug submerged hauv flux, nws tsim ib puag ncig tswj uas tiv thaiv thaj chaw soldering los ntawm cov khoom sab nraud, kom ntseeg tau tias cov pob qij txha sib xws thiab txhim khu kev qha. Qhov no ua rau muaj cov kav dej welded kauv nrog lub zog tshwj xeeb thiab ruaj khov.

Kev Xam Qhov Ntev ntawm Cov Yeeb Nkab Vuam Kauv

2. Kev ua haujlwm tau zoo dua: Kev vuam hlau uas muab kauv rau hauv qab nthab muaj kev ua haujlwm tau zoo vim nws siv tshuab ua haujlwm. Cov txheej txheem no suav nrog kev pub hlau vuam tsis tu ncua, ua rau muaj kev tsim khoom sai dua thaum tseem ua haujlwm tau zoo.
