1. Tub ntxhais tseem ceeb 1: phaj tuab ("pib" rau kev txiav txim siab)
Qhov tuab<25mm: Vuam cua sov tawm tswv yim yog qhov me me, thiab kev ntxhov siab feem ntau yog tsawg. Yog tias tus qauv yooj yim (piv txwv li, cov nqaws ncaj, tsis muaj cov pob qij txha sib luag) thiab tsis muaj kev kho mob hauv siab, kev ntxhov siab kev pab daws teeb meem yog feem ntau tsis tsim nyog.
Thickness ntau dua los yog sib npaug rau 25 hli: Lub Vuam Tshav Kub Kub -} Cov Cheeb Tsam Cuam Tshuam (Haz) yog dav dav, thiab qhov ntsuas kub ntawm Weld thiab cov hauv paus hlau yog steeper. Qhov no ua rau muaj kev nthuav dav thermal loj thiab meraction, uas ua rau muaj kev ntxhov siab ntau. Kev kho mob ntxhov siab yogpom tau pom zoo heevTshwj tsis yog tias cov qauv tsim tshwj xeeb ua rau muaj kev zam nws.
Thickness ntau dua los yog sib npaug rau 50 hli: Muaj kev ntxhov siab uas muaj kev ntxhov siab tau muaj ntau, tshwj xeeb tshaj yog nyob rau hauv multi-}} dhau welding (ib txwm muaj cov hlau tuab). Kev kho mob ntxhov siab yogYuav luag yuav tsum tau uaYuav kom tsis txhob tshaj tawm - vuam deformation, tawg, lossis txo lub neej ua haujlwm.
2. Tub ntxhais tseem ceeb 2: tus qauv tsim qauv thiab vuam cov kab mob
Cov pob txha complex lossis siab: Yog tias Q35SnH Tuab phaj tau kaw Welds, t- welded los ntawm lwm cov cheebtsam (piv txwv li kev ntxhov siab tsis tuaj yeem tso tawm los ntawm kev tawm tsam ntuj. Kev kho mob ntxhov siab yog tsim nyog los tiv thaiv kev tawg.
Kev Tawm Tshav Kub Kub Vuam Vuam: Cov txheej txheem zoo li submerged arc vuam (pom) lossis ntau {{{}} {} {} { Xav tau kev ntxhov siab yog xav tau los pab tawm cov nyhuv no.
Weld Tsis Zoo: Yog tias vuam tsis xws luag (piv txwv li, tsis tiav Fusion, Porosity) muaj nyob ib puag ncig no, nrawm nrob tawg. Hais txog kev kho mob, ua ke nrog kev kho tsis taus, yog qhov tsim nyog.
3. Tub ntxhais tseem ceeb 3: chaw pabcuam thiab kev xav tau
High - Kev Pabcuam Kev nyuaj siab: Yog tias Q355Nn tuab tuab cov qauv stoms zoo li qub / piv txwv, cov hlab ntsha siab), ua haujlwm hnyav rau kev ntxhov siab, ua rau muaj kev ntxhov siab ua ntej ua haujlwm, ua rau lub cev nqaij tawv ua haujlwm, ua rau muaj kev ntxhov siab ua ntej ua haujlwm. Kev ntxhov siab kev ntxhov siab yog yuav tsum tau ua.
Kev Pabcuam Corrosive ib puag ncig: Q355NHNH Kev Ntseeg ntawm Txheej xeb Tiv Thaiv (Patina) rau huab cua tsis kam. Residual kev ntxhov siab tuaj yeem ua rau "kev nyuaj siab corrosion tawg" (shloride {{2 {2 {2 {2 {2 {2 {2 {2} Cov chaw nyob ntug dej hiav txwv, cov chaw nyob ntawm cov pa dej hiav txwv nrog cov pa paug). Kev kho mob ntxhov siab Kev mob nkeeg no thiab ua kom cov ntaub ntawv patina sib xyaw ua ke.
Precision los yog deformation -} Cov qauv rhiab: Yog tias tus qauv yuav tsum tau ua kom nruj Ntxhov siab kev kho mob ua ntej npaj installation yog qhov tseem ceeb.
