Qhov zoo ntawm vuam yog ncaj qha ntsig txog kev nyab xeeb thiab ruaj khov ntawm cov khoom. Yog li txhawm rau xyuas qhov zoo ntawm cov khoom siv welded, peb yuav tsum xyuam xim rau dab tsi?

Ua ntej, steel yeeb nkab thickness. Hauv kev tsim thiab siv cov txheej txheem ntawm welded steel kav, lub thickness ntawm cov yeeb nkab steel yog qhov tseem ceeb heev. Txawm li cas los xij, vim yog vim li cas thiab kev tsim khoom, tej zaum yuav muaj qee qhov sib txawv ntawm cov yeeb nkab steel. Cov qauv no qhia cov kev txwv xws li qhov loj, tuab, qhov hnyav, thiab kev kam rau siab ntawm cov kav hlau welded los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm cov kav hlau. Deviations nyob rau hauv lub thickness ntawm welded steel kav yuav cuam tshuam qhov zoo thiab kev nyab xeeb ntawm cov kav hlau. Yog hais tias lub thickness sib txawv ntawm cov yeeb nkab steel loj heev, lub peev xwm thauj khoom ntawm cov yeeb nkab steel yuav raug txo, yog li cuam tshuam rau kev nyab xeeb thiab ruaj khov ntawm cov khoom. Txhawm rau tswj qhov sib txawv ntawm qhov tuab ntawm welded steel kav, cov txheej txheem thoob ntiaj teb feem ntau teev cov qauv rau kev tso cai sib txawv ntawm cov thickness ntawm welded steel kav. Hauv kev tsim khoom thiab kev siv tiag tiag, nws yuav tsum tau tswj hwm thiab tswj nruj nruj los ntawm cov qauv kom ntseeg tau tias qhov zoo thiab kev nyab xeeb ntawm cov kav hlau steel. nruj me ntsis tswj cov thickness ntawm steel kav. Cov yeeb nkab steel ntawm tib qhov tshwj xeeb muaj lub thickness kam rau ua ntawm ± 5%. Peb nruj me ntsis tswj qhov zoo ntawm txhua cov yeeb nkab steel. Peb ua cov kev ntsuam xyuas tuab ntawm txhua pawg ntawm cov kav hlau los tiv thaiv cov khoom tsis zoo los ntawm kev nkag mus rau hauv kev ua lag luam, tiv thaiv cov cai thiab kev nyiam ntawm cov neeg siv khoom, thiab xyuas kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm txhua cov yeeb nkab steel.

Thib ob, lub nozzle. Hauv cov txheej txheem ntawm cov yeeb nkab steel vuam, lwm qhov tseem ceeb yog kev kho lub nozzle ntawm cov yeeb nkab steel. Txawm hais tias nws tsim nyog rau vuam yuav cuam tshuam rau qhov zoo ntawm cov khoom welded. Ua ntej, nws yog ib qho tsim nyog yuav tsum khaws cov yeeb nkab steel lub qhov ncauj kom tsis txhob muaj xeb, av, thiab roj. Cov khib nyiab no cuam tshuam rau qhov zoo ntawm vuam, ua rau qhov tsis sib xws thiab tawg ntawm qhov vuam thaum lub sij hawm vuam, thiab txawm cuam tshuam rau tag nrho cov khoom welded. Kev sib tw du kuj yog ib qho tseem ceeb uas yuav tsum tau ua ua ntej vuam. Yog hais tias qhov cross-section inclination lub kaum sab xis loj heev, lub pob tw vuam ntawm cov yeeb nkab steel yuav khoov thiab lub kaum sab xis yuav tshwm sim, uas yuav cuam tshuam rau kev siv. Thaum lub sij hawm welding, koj yuav tsum tau xyuas cov burrs thiab txuas ntawm qhov tawg ntawm cov yeeb nkab steel, txwv tsis pub, vuam yuav ua tsis tau. Burrs ntawm cov kav hlau tuaj yeem khawb cov neeg ua haujlwm thiab ua rau lawv cov khaub ncaws puas thaum ua, uas cuam tshuam rau kev nyab xeeb. Xav txog cov neeg siv cov teeb meem vuam, lub nozzle ua tshuab tau ntxiv rau cov txheej txheem los xyuas kom meej tias lub nozzle interface yog du, tiaj tus, thiab tsis muaj burr. Thaum lub sij hawm vuam, tsis tas yuav rov txiav lub nozzle, ua kom yooj yim rau cov neeg siv pob tw weld hauv kev siv txhua hnub. Kev siv cov txheej txheem no tuaj yeem tsis tsuas yog txo cov khoom pov tseg ntawm cov ntaub ntawv pov tseg uas peb tau siv los pom thaum lub sij hawm vuam, tab sis kuj ua kom cov khoom siv tau zoo, txo cov vuam deformation, thiab txhim kho qhov vuam zoo ntawm cov khoom.

Thib peb, welded steel yeeb nkab welds xa mus rau welds tsim thaum lub sij hawm vuam txheej txheem ntawm steel kav. Qhov zoo ntawm cov yeeb nkab steel welds ncaj qha cuam tshuam rau kev ua haujlwm thiab kev nyab xeeb ntawm cov kav hlau steel. Yog tias muaj qhov tsis xws luag hauv cov yeeb nkab steel vuam, xws li pores, slag inclusions, tawg, thiab lwm yam, nws yuav cuam tshuam rau lub zog thiab sealing ntawm cov yeeb nkab steel, ua rau muaj teeb meem xws li cov ntsiab lus to thiab tawg hauv cov yeeb nkab steel thaum lub sij hawm vuam. , yog li cuam tshuam rau qhov zoo thiab kev nyab xeeb ntawm cov khoom. Yog li ntawd, thaum lub sij hawm tsim thiab siv cov yeeb nkab steel, kev tswj xyuas nruj thiab kev ntsuam xyuas ntawm cov yeeb nkab steel yuav tsum tau ua kom ntseeg tau tias cov kav dej steel zoo thiab kev nyab xeeb. Txhawm rau kom ntseeg tau qhov zoo ntawm vuam, peb tshwj xeeb ntxiv cov khoom siv turbine vuam nrhiav kom tau cov kab ntau lawm txhawm rau txheeb xyuas cov txheej txheem vuam ntawm txhua cov yeeb nkab steel. Thaum lub sij hawm tsim cov txheej txheem, yog tias vuam teeb meem tshwm sim, peb yuav tam sim ntawd hu rau tub ceev xwm los tiv thaiv cov khoom muaj teeb meem los ntawm kev raug xa mus rau hauv lub teb chaws, nyob rau hauv lub tiav lawm pob khoom. Kev kuaj tsis muaj kev puas tsuaj, kev tshuaj ntsuam xyuas metallographic, kev ntsuas cov cuab yeej cuab tam, thiab lwm yam yog ua rau txhua pawg ntawm cov kav hlau xa tawm los ntawm lub Hoobkas kom ntseeg tau tias cov neeg siv khoom qis tsis raug kev txom nyem los ntawm cov khoom tsis ruaj khov thiab kev ua haujlwm qeeb hauv kev ua haujlwm vuam vim muaj teeb meem ntawm cov yeeb nkab steel thaum lub sij hawm. kev ua haujlwm.
