1. Kev npaj kev tsim kho: Paub koj tus kheej nrog cov duab kos → Ua ib qho chaw soj ntsuam → Txiav txim siab txiav qhov ntev raws li qhov loj ntawm qhov chaw.
2. Kev txiav cov yeeb nkab: thauj cov yeeb nkab seem yuav raug txiav mus rau qhov chaw nruab thiab txiav rau hauv av kom ntev li ntev tau. Lub luj tshib yog ua los ntawm cov pa oxygen - dawb acetylene nplaim taws. Tom qab txiav, txhuam sab hauv thiab sab nraud ntawm lub bevel kom tshem tawm cov burrs thiab cov npoo ntse, tiv thaiv kev ntxhov siab hauv cheeb tsam txiav, uas tuaj yeem ua rau vuam deformation lossis kev ntxhov siab tawg.
3. Pairing thiab Installation: Muab ob lub yeeb nkab txuas ua ke, kho qhov sib txawv bevel kom ntseeg tau tias kev sib dhos zoo. Vuam deformation raug txiav txim siab thaum sib dhos, thiab cov txheej txheem tiv thaiv -deformation feem ntau yog siv rau kev kho ua ntej. Thaum sib dhos, xav txog kev yooj yim ntawm kev ua haujlwm thiab kev nyab xeeb; zam kev quab yuam tawm tsam cov yeeb nkab ntu kom tiv thaiv kev puas tsuaj rau phab ntsa stainless hlau yeeb nkab.
4. Weld Kho: Yog tias cov kav dej tau pom tias tsis tsim nyog tom qab tsis yog- kuaj kev puas tsuaj, nws yuav tsum tau kho los ntawm vuam. Kev npaj kho yuav tsum tau tsim thiab pom zoo los ntawm cov thawj coj. Qib ntawm kev kho vuam yuav tsum tsis txhob qis dua qhov tsawg kawg nkaus uas tau teev tseg hauv cov qauv tsim nyog. Welds uas feem ntau tsis pub rov ua dua tshiab muaj qhov tsis xws li porosity, slag inclusions, tsis muaj fusion, thiab tawg.
