Lub vuam kev nyuaj siab ntawm qhov nruab nrab zaus qhov chaw welder yog qhov kev ntxhov siab los ntawm kev vuam ntawm cov khoom siv welded. Lub hauv paus ua rau vuam kev ntxhov siab thiab deformation yog qhov tsis sib xws ntawm qhov kub thiab txias thiab cov yas deformation hauv zos thiab txawv cov qauv ntim tshwj xeeb los ntawm nws.
Hais txog qhov kev ntxhov siab tsim nyob rau hauv welment. Nws yog lub ntsiab ua rau cov qauv deformation thiab tawg tsim. Vuam kev ntxhov siab tuaj yeem muab faib ua cov kev ntxhov siab tsis ntev los no thiab cov welding residual stress. Kev ntxhov siab tso tawm: yog hais txog qhov tshwm sim uas qhov kev ntxhov siab ntawm qee qhov taw tes hauv cov khoom raug txo vim qhov tso tawm ntawm lub zog; Lub zog tso tawm, kom meej.
Thaum qhov kub tsis sib xws tshwm sim los ntawm vuam tsis tau ploj mus, qhov kev ntxhov siab thiab deformation nyob rau hauv lub vuam yog hu ua transient welding stress thiab deformation. Qhov kev ntxhov siab thiab deformation tom qab vuam qhov kub thiab txias yog hu ua residual welding stress thiab deformation.
Nyob rau hauv cov xwm txheej uas tsis muaj kev quab yuam sab nraud, lub vuam kev nyuaj siab yog sib npaug hauv qhov vuam. Lub vuam kev nyuaj siab thiab deformation yuav cuam tshuam rau kev ua haujlwm thiab cov tsos ntawm cov vuam nyob rau hauv qee yam mob.
