Nyob rau hauv lub tshav pob ntawm vuam, ua kom tiav qhov zoo tshuav nyiaj li cas ntawm vuam tsis yog ib qho tseem ceeb los xyuas kom meej muaj zog thiab txhim khu kev qha kev sib txuas. Ib qho tseem ceeb parameter hauv flash butt vuam yog qhov vuam tam sim no. Thaum cov vuam tam sim no tsawg dhau, nws tuaj yeem ua rau muaj ntau yam teeb meem thiab cuam tshuam qhov zoo ntawm cov vuam. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog ntau yam teeb meem uas tuaj yeem tshwm sim thaum qhov tam sim no tsis txaus nyob rau hauv flash pob tw welding.
- Tsis tiav Fusion: Tsis txaus vuam tam sim no tuaj yeem ua rau tsis tiav fusion ntawm ob daim hlau txuas. Qhov no txhais tau hais tias cov hlau tsis tuaj yeem yaj tag nrho thiab sib txuas ua ke, ua rau cov hlau tsis muaj zog thiab tsis muaj kev ntseeg siab. Tsis tiav fusion yog ib qho teeb meem tshwm sim thaum tam sim no tsawg dhau, vim tias cov cua sov tsim tawm tsis tsim nyog los tsim lub pas dej molten.
- Kev nkag mus tsis zoo: Kev nkag mus zoo yog qhov tseem ceeb los xyuas kom meej lub zog thiab kev ncaj ncees ntawm cov vuam. Thaum lub vuam tam sim no tsis txaus, qhov vuam yuav tsis muaj qhov tsim nyog qhov tob, ua rau tsis zoo nkag mus. Qhov no tuaj yeem ua rau tsis muaj zog ntawm kev sib koom ua ke, ua rau nws muaj peev xwm ua tsis tau raws li kev ntxhov siab lossis kev ntxhov siab.
- Porosity: Tsawg vuam tam sim no tuaj yeem ua rau tsim cov hnab ntim roj hauv qhov vuam, ua rau porosity. Cov hnab ntim roj no tuaj yeem cuam tshuam cov txheej txheem kev ncaj ncees ntawm kev sib koom ua ke thiab ua rau nws muaj kev cuam tshuam rau corrosion. Lub xub ntiag ntawm porosity nyob rau hauv ib tug weld feem ntau yog ib qho kev qhia ntawm cov vuam tsis zoo.
- Tsis muaj zog Mechanical Properties: Tsim nyog vuam tam sim no yog qhov tseem ceeb kom tau txais cov khoom siv kho tshuab uas xav tau hauv cov vuam, xws li lub zog tensile thiab ductility. Thaum qhov tam sim no qis dhau lawm, qhov tshwm sim weld tuaj yeem ua rau txo lub zog thiab tawv, ua rau nws tsis tsim nyog rau cov ntawv thov uas yuav tsum muaj kev ua haujlwm siab.
- Muaj kev pheej hmoo ntawm kev tawg: Tsis txaus tam sim no tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tawg hauv qhov vuam thiab thaj chaw uas muaj cua sov nyob ib puag ncig. Cov kab nrib pleb tuaj yeem nthuav tawm los ntawm kev sib txuas thiab cuam tshuam cov qauv kev ncaj ncees ntawm tag nrho cov khoom. Qhov no yog qhov teeb meem loj uas tuaj yeem ua rau cov khoom tsis ua haujlwm thiab kev txhawj xeeb txog kev nyab xeeb.
- Welds tsis ntseeg siab: Thaum kawg, thaum vuam tam sim no tsawg dhau, nws tuaj yeem ua rau cov welds tsis tuaj yeem ua tsis tau raws li cov qauv kev lag luam lossis cov kev cai. Cov subpar welds no tuaj yeem ua rau raug nqi rov ua dua tshiab, kho dua tshiab, lossis txawm tias qhov seem ntawm cov khoom siv welded.
Hauv kev xaus, qhov vuam tam sim no yog qhov tseem ceeb hauv kev sib tsoo pob tw, thiab nws qhov tsis txaus tuaj yeem ua rau muaj ntau yam teeb meem. Txhawm rau ua kom cov welds zoo thiab muaj zog, txhim khu kev qha kev sib txuas, nws yog ib qho tseem ceeb rau kev teeb tsa cov vuam tam sim no ntawm qhov tsim nyog, suav nrog cov khoom siv, tuab, thiab lwm yam cuam tshuam rau hauv cov txheej txheem vuam. Kev cob qhia tsim nyog thiab kev saib xyuas yog qhov tseem ceeb los tiv thaiv cov teeb meem uas tau tham saum toj no thiab ua kom muaj kev ncaj ncees ntawm cov khoom siv welded.
