Raws li cov khoom tseem ceeb ntawm cov khoom siv hauv kev lag luam, kev siv cov khoom siv welded ncaj qha cuam tshuam rau kev ruaj ntseg thiab kev pab cuam lub neej ntawm tag nrho cov qauv. Kev paub txog kev siv txuj ci tshawb fawb thaum lub sij hawm sib dhos thiab kev pabcuam tuaj yeem txo cov kev pheej hmoo thiab ua kom muaj txiaj ntsig zoo ntawm cov khoom siv welded.
Ua ntej, ua ntej kev sib sau ua ke, kev tshuaj xyuas tag nrho ntawm cov ntaub ntawv pov thawj zoo thiab cov ntaub ntawv tshuaj xyuas ntawm cov khoom siv welded yuav tsum tau ua kom ntseeg tau tias qhov tsis muaj qhov cuam tshuam ntawm qhov tsis xws luag lossis sab hauv tsis zoo tshaj cov qauv. Rau cov welds nrog me ntsis spatter los yog slag, lawv yuav tsum tau muab ntxuav kom huv si nrog cov cuab yeej tshwj xeeb los tiv thaiv cov seem los ntawm kev cuam tshuam kev sib dhos qhov tseeb lossis ua rau muaj kev ntxhov siab. Nyob rau tib lub sijhawm, qhov ntev geometric thiab kam rau ua ntawm cov khoom siv welded yuav tsum tau kuaj xyuas, ua tib zoo saib xyuas qhov flatness thiab perpendicularity ntawm qhov tseem ceeb mating nto. Yog tias tsim nyog, kev sib txawv yuav tsum raug kho los ntawm kev siv tshuab los tiv thaiv kev puas tsuaj ntxiv rau cov welds los ntawm kev sib dhos yuam kev.
Thaum lub sij hawm sib dhos, symmetrical, kauj ruam -los ntawm- kauj ruam nruj txoj kev yuav tsum tau ua ntej kom ruaj ntseg welded Cheebtsam, tsis txhob deformation ntawm welded cheeb tsam tshwm sim los ntawm unilateral quab yuam. Rau cov welded loj los yog tsawg dua nruj, ua ntej- teeb tsa los tiv thaiv- kev ntsuas deformation lossis cov khoom siv txhawb nqa tuaj yeem siv los tiv thaiv kev deformation los ntawm qhov seem welding. Thaum bolting, nruj nreem sib npaug rau tus nqi torque tsim, zam dhau - zawm lossis qis dua - zawm kom tsis txhob threaded qhov tawg lossis ntxiv load rau ntawm qhov vuam. Yog tias muaj ntau lub welded Cheebtsam yuav tsum tau disassembled rau kev siv, lub load -cov kabmob muaj peev xwm ntawm cov thawj welded pob qij txha yuav tsum tau soj ntsuam kom tsis txhob siv cov concentrated loads rau qhov chaw tsis muaj zog ntawm weld.
Kev pabcuam-theem tu yog qhov tseem ceeb sib npaug. Kev tshuaj xyuas tsis tu ncua ntawm cov khoom siv welded 'zoo li yog tsim nyog, tsom rau welds thiab tshav kub- thaj chaw cuam tshuam rau cov cim ntawm kev tawg, xeb thinning, lossis deformation. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom uas raug hloov pauv los yog qhov chaw corrosive, qhov kev tshuaj xyuas zaus yuav tsum tau nce. Cov kuab tshuaj nruab nrab yuav tsum tau siv los ntxuav kom tsis txhob muaj cov kua qaub thiab alkalis corroding lub vuam hlau. Yog tias pom muaj kev puas tsuaj hauv cheeb tsam, tus kws tshaj lij yuav tsum ntsuas qhov ua tau ntawm kev kho; qhov muag tsis pom kev kho welds uas cuam tshuam qhov kev sib txuas ntawm cov qauv qub yog nruj me ntsis txwv. Tsis tas li ntawd, welded Cheebtsam yuav tsum tsis txhob ua haujlwm rau lub sijhawm ntev ntawm qhov kub siab tshaj qhov tsim kub, vim tias qhov kub thiab txias ua kom cov vuam aging, txo qhov toughness thiab lub zog.
Kev siv cov txheej txheem tsim nyog yog qhov tseem ceeb thoob plaws lub neej ntawm cov khoom siv welded, los ntawm kev npaj ua ke mus rau kev saib xyuas niaj hnub. Txhua kauj ruam yuav tsum hwm cov khoom siv thiab cov txheej txheem txheej txheem. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tus nqi engineering ntawm cov khoom siv welded maximized, muab cov khoom lav rau kev nyab xeeb thiab ruaj khov ntawm cov khoom siv.
