1.Kuj kuj muaj cov kav hlau steel nyob rau hauv nominal txheej kab thiab nominal phab ntsa thickness ntawm lawv nyob ib sab qhov ntau thiab tsawg teev nyob rau hauv lub rooj, tab sis ib daim ntawv cog lus yuav tsum tau kos npe rau.
2. Cov nominal txheej diameters nyob rau hauv brackets nyob rau hauv lub rooj yog reserved diameters.
Ib qho tseem ceeb tshaj plaws ntawm kev siv kauv hlaucov kav dej rau cov kab hauv avyog cov txheej txheem vuam kom raug.Vuam yog txheej txheem ntawm kev koom nrog ob qhov hlau los ntawm kev siv cov cua sov thiab siab.Rau cov kav dej hauv av, vuam zoo ncaj qha cuam tshuam rau tag nrho kev ncaj ncees thiab kev ntseeg siab ntawm cov kav dej.
Tsim nyogcov txheej txheem weldingrau kauv steel yeeb nkab koom nrog ob peb kauj ruam tseem ceeb.Ua ntej, qhov saum npoo ntawm cov yeeb nkab yuav tsum tau welded yuav tsum huv thiab tsis muaj cov kab mob xws li av, roj, lossis xim.Qhov no ua kom cov weld muaj zog thiab tsis muaj impurities uas tuaj yeem cuam tshuam nws lub zog.
Tom ntej no, vuam tsis xws li cua sov input, vuam ceev, thiab cov txheej txheem yuav tsum tau ua tib zoo tswj kom ua tau zoo welds.Kev siv cov khoom siv vuam zoo thiab cov txheej txheem yog qhov tseem ceeb rau kev tiv thaiv qhov tsis xws luag xws li porosity, tawg, lossis tsis muaj fusion, uas tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm cov vuam.
Tsis tas li ntawd, cov txheej txheem preheating thiab kev kho cua sov tom qab vuam yog qhov tseem ceeb rau cov kav hlau uas siv rau hauv cov kav dej hauv av.Preheating pab txo qhov kev pheej hmoo ntawm kev tawg thiab txhim kho tag nrho cov weld zoo, thaum tom qab vuam kev kho cua sov txo cov kev ntxhov siab uas seem thiab ua kom muaj kev sib txig sib luag thoob plaws hauv cheeb tsam weld.
Tsis tas li ntawd, kev siv cov thev naus laus zis vuam thev naus laus zis xws li cov txheej txheem vuam tshuab tsis siv neeg thiab kev sim tsis muaj kev puas tsuaj tuaj yeem txhim kho qhov zoo thiab kev ntseeg siab ntawm vuam.Cov thev naus laus zis no pab xyuas kom cov welded pob qij txha ua tau raws li qhov tsim nyog lub zog thiab cov qauv zoo los muab kev thaj yeeb ntawm lub siab txog kev ua haujlwm ntev ntawm cov kab hauv av.
Hauv cov ntsiab lus, cov txheej txheem vuam cov yeeb nkab kom raug yog qhov tseem ceeb los ua kom muaj kev ncaj ncees thiab kev ua neej ntev ntawm cov kav hlau kav siv hauv cov kab dej hauv av.Los ntawm kev ua raws li qhov tsim nyog welding tsis, cov txheej txheem thiab kev tswj xyuas zoo, qhov kev pheej hmoo ntawm vuam tsis xws luag thiab tsis ua haujlwm tuaj yeem txo qis.Qhov tshwm sim yog cov kab dej hauv av txhim khu kev qha thiab ruaj khov uas tuaj yeem tiv taus qhov kev sim ntawm lub sijhawm thiab muab kev pabcuam xa dej nyab xeeb thiab ua haujlwm tau zoo.Rau cov kab dej hauv av, kev nqis peev hauv cov txheej txheem vuam kom zoo yog ib kauj ruam tseem ceeb hauv kev ua kom ntseeg tau tag nrho cov kav dej thiab kav ntev.
