Kev puas tsuaj ntawm vuam kev nyuaj siab ntawm qhov nruab nrab zaus qhov chaw vuam tshuab feem ntau yog siv rau hauv 6 yam: 1, vuam lub zog; 2, vuam nruj; 3, stability ntawm vuam qhov chaw; 4, kev ua haujlwm raug; 5, seem stability; 6. Corrosion kuj. Cov nram qab no me me series rau koj los qhia kom meej:
Qhov cuam tshuam rau lub zog: Yog tias muaj qhov tsis zoo nyob rau hauv qhov chaw siab tensile kev ntxhov siab, thiab qhov vuam yog ua haujlwm ntawm qhov kub thiab txias hloov pauv, qhov vuam seem yuav txo tau lub zog zoo li qub. Nyob rau hauv qhov kev txiav txim ntawm cyclic kev nyuaj siab, yog hais tias cov residual tensile kev nyuaj siab tshwm sim nyob rau hauv cov kev nyuaj siab concentration, lub vuam residual tensile kev nyuaj siab yuav txo tau lub qaug zog ntawm lub weldment.
Kev cuam tshuam ntawm qhov tawv nqaij: qhov vuam seem ntawm qhov kev ntxhov siab thiab kev ntxhov siab tshwm sim los ntawm kev thauj khoom sab nraud, tuaj yeem ua rau vuam qhov tawm los ua ntej thiab tsim cov yas deformation. Qhov nruj ntawm qhov vuam yuav raug txo raws li qhov tshwm sim.
Kev cuam tshuam ntawm kev ruaj ntseg ntawm lub siab welded qhov chaw: thaum lub vuam pas nrig yog nyob rau hauv siab, lub vuam seem kev nyuaj siab thiab kev nyuaj siab tshwm sim los ntawm lub sab nraud load yog superimposed, uas tej zaum yuav ua rau tus pas nrig hauv zos yield los yog ua rau tus pas nrig hauv zos instability, thiab tag nrho. stability ntawm tus pas nrig yuav raug txo. Kev cuam tshuam ntawm kev ntxhov siab nyob rau hauv kev ruaj ntseg yog nyob ntawm qhov geometry ntawm cov tswv cuab thiab kev faib tawm ntawm kev ntxhov siab sab hauv. Qhov cuam tshuam ntawm qhov kev ntxhov siab ntawm qhov seem ntawm qhov tsis raug kaw (xws li I-section) yog ntau dua li ntawm seem kaw (xws li seem lub thawv).
Kev cuam tshuam ntawm machining raug: Lub hav zoov ntawm welding residual kev nyuaj siab muaj ntau theem ntawm kev cuam tshuam rau lub machining raug ntawm weldparts. Qhov me me qhov nruj ntawm qhov vuam, qhov ntau dua qhov ua tiav, thiab qhov cuam tshuam ntau dua rau qhov raug.
Kev cuam tshuam ntawm qhov ruaj khov ntawm qhov ntev: Cov vuam seem ntawm qhov kev ntxhov siab hloov nrog lub sijhawm, thiab qhov loj ntawm qhov vuam kuj hloov. Qhov seem stability ntawm welded qhov chaw kuj cuam tshuam los ntawm stability ntawm residual kev nyuaj siab.
Qhov cuam tshuam rau corrosion kuj: Vuam residual stress thiab load stress kuj yuav ua rau kev nyuaj siab corrosion cracking.
