Raws li kev sib txuas tseem ceeb hauv cov cuab yeej siv thiab cov qauv tsim vaj tsev, qhov kev pabcuam ruaj khov ntawm cov khoom siv welded yog nyob ntawm kev tshawb fawb lub voj voog txij nkawm.Lub voj voog txij nkawm tsis yog lub sijhawm tas sijhawm, tab sis lub tswv yim tsim tawm los ntawm kev xav txog ntau yam xws li cov khoom siv, kev pabcuam ib puag ncig, cov yam ntxwv ntawm kev thauj khoom, thiab cov txiaj ntsig kev soj ntsuam keeb kwm. Nws lub hom phiaj yog txhawm rau tshawb xyuas qhov tsis xws luag, ncua kev ua haujlwm tsis zoo, txuas ntxiv lub neej kev pabcuam, thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
Los ntawm cov khoom pom, rau cov khoom siv carbon steel welded nyob rau hauv qhuav, ib txwm - qhov kub thiab txias ib puag ncig nrog cov khoom ruaj khov thiab tsis muaj cov xov xwm corrosive, niaj hnub kev tshuaj xyuas qhov muag tuaj yeem ua txhua peb mus rau rau lub hlis, tsom rau kev tshuaj xyuas qhov pib tawg, xeb thinning, los yog deformation nyob rau hauv vuam thiab tshav kub- cuam tshuam cheeb tsam. Rau cov khoom zoo sib xws hauv cov av noo, tshuaj tsuag ntsev, lossis cov tshuaj corrosive ib puag ncig, qhov zaus yuav tsum tau luv luv mus rau ib hlis ib zaug, ntxiv los ntawm qhov tsis yog -kev sim ua kom puas tsuaj los ntsuas kev txhim kho ntawm kev puas tsuaj sab hauv. Tsawg- alloy siab- lub zog steel welded Cheebtsam, uas nws lub zog reserves nyob ntawm qhov zoo-grained microstructure thiab lub xeev kev ntxhov siab, yog rhiab heev rau qaug zog thiab nkig puas. Nyob rau hauv dynamic loads los yog qis -kub tej yam kev mob, ib tug systematic tshuaj ntsuam xyuas yuav tsum tau ua txhua txhua ob mus rau peb lub hlis, nrog rau nto magnetic particle los yog penetrant testing thiab tsim nyog ultrasonic sampling.
Thaum stainless hlau welded Cheebtsam muaj corrosion kuj zoo, pitting los yog intergranular corrosion kuj tseem tuaj yeem tshwm sim hauv chloride -muaj lossis siab - qhov kub thiab txias. Nws raug pom zoo kom ua morphology thiab thickness checks txhua rau lub hlis, ua ke nrog tshuaj ntxuav. Rau cov ntim khoom uas muaj lub siab tseem ceeb lossis kev thauj khoom, kev ruaj ntseg vuam yuav tsum tau tshuaj xyuas peb lub hlis twg. Tsis yog -ferrous hlau welded Cheebtsam, xws li txhuas thiab tooj liab alloys, yog nquag oxidation vim lawv ceev thermal conductivity. Hauv hluav taws xob lossis siab - cov khoom siv kub, yuav tsum tau them nyiaj rau kev hloov pauv hauv kev sib koom ua ke thiab thermal loosening. Kev sib txuas ceev thiab qhov chaw saum npoo yuav tsum raug kuaj xyuas txhua plaub mus rau rau lub hlis, thiab nyob rau hauv siab - qhov kub thiab txias, qhov no yuav tsum tau nce ntxiv rau txhua hli.
Load yam ntxwv yog lwm yam tseem ceeb uas txiav txim siab txij nkawm zaus. Rau cov welded thav duab, cov qauv raug ncua, lossis cov khoom sib kis tau raug hloov pauv, cov kab nrib pleb tuaj yeem tsim thiab nthuav tawm sai. Kev ntsuam xyuas yuav tsum yog raws li kev ntxhov siab amplitude thiab lub voj voog suav, ua haujlwm saib xyuas online lossis kuaj ultrasonic thiab radiographic, nrog rau luv luv li txhua hli lossis ntau zaus. Rau kev txhawb nqa- hom welded Cheebtsam nyob rau hauv cov khoom zoo li qub thiab nyob rau hauv ib puag ncig me me, lub caij nyoog tuaj yeem ua kom haum, nrog rau peb lub hlis twg lossis ib nrab- ib xyoos ib zaug raws li qhov ntsuas.
Nyob rau hauv kev xyaum, ib tug qauv tsom xam mechanism raws li cov ntaub ntawv keeb kwm yuav tsum tau tsim los sib piv cov kev xeem xeem yav dhau los nrog rau cov kev pab cuam tsis thiab dynamically kho ncua ncua sij hawm. Rau cov cheeb tsam uas kuaj pom muaj qhov tsis zoo, yuav tsum tau kuaj tam sim thiab siv zog ntxiv, nrog rau kev kho lossis thauj khoom- txwv kev ntsuas, tsim qhov kaw- lub voj kev tswj hwm ntawm "kev tshawb nrhiav- kev ntsuas- kho- rov- tshuaj xyuas."
Kev tshawb fawb zoo thiab tsim nyog txij nkawm lub voj voog rau cov khoom siv welded yog lub hauv paus rau kev tiv thaiv kev saib xyuas thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav tam sim ntawd. Nws tseem yog ib qho kev ntsuas tsim nyog los xyuas kom meej lub sijhawm ntev - kev nyab xeeb kev ua haujlwm thiab kev lag luam ntawm cov cuab yeej siv. Tsuas yog los ntawm kev sib koom ua ke nrog kev tshuaj xyuas ib ntus nrog cov kev ua haujlwm tiag tiag tuaj yeem ua cov khoom siv txuas ntxiv ua lawv cov haujlwm txhim khu kev qha.
