1.Dab tsi txiav txim siab seb lub vuam puas muaj zog txaus?
Tensile Strength: Qhov no yog qhov taw qhia tseem ceeb tshaj plaws. Kev ntsuas tensile yog ua los ntawm kev ncab ib qho qauv welded kom txog thaum nws tawg, piv nws lub zog tensile rau cov khoom siv hauv paus. Hauv kev xyaum ua ntau lawm, lub zog vuam ntau dua lossis sib npaug li 85% ntawm cov khoom siv lub hauv paus yog suav tias txaus rau cov kev xav tau tom ntej.
Plasticity (Bending Performance): Lub vuam yuav tsum muaj lub zog thiab tawv. Rov ua dua cov kev sim khoov yog siv los txiav txim seb muaj pes tsawg 90℃khoov lub vuam tuaj yeem tiv taus yam tsis muaj kev tawg. Rau qee cov qib steel tshwj xeeb (xws li qib siab - qib silicon steel thiab martensitic stainless hlau), qhov vuam toughness qis dua; Feem ntau, ib qho rov khoov yam tsis muaj kev tawg yog suav tias tsim nyog.
Formability (Cupping Test): Qhov no simulates lub stamping xeem. Lub punch yog siv los thawb cov qauv welded tawm ntawm cov khoom siv kom txog thaum tawg.
Txais tau: Cov kab nrib pleb yog los ntawm cov khoom siv hauv paus (qhia tias cov vuam muaj zog dua li cov khoom siv hauv paus).
Kev lees txais tsis tau: Cov kab nrib pleb txuas ntxiv raws qhov vuam (qhia qhov vuam yog qhov tsis muaj zog).
2.Yuav ua li cas welding tsis cuam tshuam lub zog vuam?
Kev teeb tsa tsis raug xws li laser zog, vuam ceev, thiab defocusing tus nqi.
Kev nkag mus tsis tiav lossis overheating ua rau lub zog poob qis.
3.Yuav ua li cas cov khoom sib txawv cuam tshuam rau weld lub zog?
Ob qhov txias txias -rolled coils txawv ntau dhau hauv qib, tuab, thiab qhov chaw nyob (nrog lossis tsis muaj txheej).
Tsis sib xws microstructure nyob rau hauv cheeb tsam weld tuaj yeem yooj yim ua qhov pib taw tes rau cov kab nrib pleb.
4.Qhov kev huv huv cuam tshuam li cas rau lub zog vuam?
Qhov chaw weld muaj cov roj, cov ntaub ntawv hlau, lossis oxide nplai.
Welding defects xws li porosity thiab slag inclusions tuaj yeem tshwm sim, ua qhov chaw ntawm pob txha.
5.Dab tsi cov tswv yim tswv yim koj muaj?
Ua ntej stamping, paub meej tias qhov chaw weld: Yog tias qhov chaw stamped suav nrog cov vuam, nws raug nquahu kom kho cov txheej txheem kom ntseeg tau tias qhov vuam tsis txhob muaj qhov tseem ceeb (xws li siab - tensile sidewalls thiab khoov cov hauv paus hniav). Txawm tias muaj zog txaus, thaj tsam weld muaj qis plasticity dua li cov khoom siv hauv paus, thiab yuam kev deformation tuaj yeem ua rau tawg yooj yim.
Ua tib zoo saib xyuas qhov sib txawv ntawm cov hlau sib txawv: Yog tias koj cov kab ntau lawm yuav tsum tau vuam cov qib sib txawv ntawm qhov txias- dov coils (xws li cov qis qis- carbon steel thiab siab - lub zog steel) ua ke, tshwj xeeb kev txheeb xyuas qhov kev ua tau zoo ntawm vuam yog tsim nyog.
Xa mus rau qhov yooj yim ntawm - kev soj ntsuam ntawm qhov chaw: Kev xeem Cupping lossis kev sim khoov feem ntau yog siv rau ntawm cov kab ntau lawm kom ceev thiab siv tau qhov chaw kuaj xyuas qhov zoo.
