Yuav Tshawb Xyuas Vuam Zoo li cas hauv Butt Vuam Tshuab?

Xyuas kom qhov zoo ntawm welds nyob rau hauv lub taub qab vuam tshuab yog qhov tseem ceeb rau kev ntseeg siab thiab kev nyab xeeb ntawm cov qauv welded.Kab lus no delves rau hauv ntau txoj hauv kev thiab cov txheej txheem siv los tshuaj xyuas cov vuam zoo hauv lub taub qab vuam tshuab, hais txog qhov tseem ceeb ntawm cov txheej txheem tshuaj xyuas nruj.

Butt welding tshuab

  1. Kev tshuaj xyuas qhov muag:
    • Qhov tseem ceeb:Kev tshuaj xyuas qhov muag yog qhov yooj yim tshaj plaws thiab thawj txoj hauv kev los ntsuas qhov vuam zoo.
    • Txheej txheem:Cov kws tshuaj ntsuam xyuas pom pom cov welded sib koom ua ke kom pom qhov tsis xws luag xws li tawg, undercuts, tsis tiav fusion, los yog ntau porosity.Qhov kev tshuaj xyuas no feem ntau ua tam sim tom qab vuam thiab dua tom qab kev kho mob tom qab vuam.
  2. Dimensional soj ntsuam:
    • Qhov tseem ceeb:Dimensional raug yog qhov tseem ceeb rau kev ncaj ncees ntawm cov qauv, ua qhov kev soj ntsuam qhov ntev yog qhov tseem ceeb.
    • Txheej txheem:Cov kev ntsuas meej raug coj los xyuas kom meej qhov vuam qhov ntev phim cov qauv tsim tshwj xeeb.Qhov no suav nrog kev ntsuas qhov dav ntawm qhov vuam, qhov tob, thiab tag nrho cov geometry.
  3. Kev Ntsuas Tsis Muaj Kev Puas Tsuaj (NDT):
    • Qhov tseem ceeb:NDT cov txheej txheem tso cai rau kev soj ntsuam kom ntxaws yam tsis muaj kev puas tsuaj rau qhov sib koom ua ke.
    • Txheej txheem:Ntau txoj hauv kev NDT, xws li kev kuaj ultrasonic, kuaj hluav taws xob, kuaj cov khoom sib nqus, thiab kuaj cov xim dye penetrant, tuaj yeem ua haujlwm txhawm rau txheeb xyuas cov teeb meem sab hauv, kev tsis sib xws, lossis cov khoom tsis sib xws hauv qhov vuam.
  4. Mechanical Testing:
    • Qhov tseem ceeb:Mechanical xeem ntsuas lub zog thiab ductility ntawm weld.
    • Txheej txheem:Tensile, cuam tshuam, thiab hardness tests yog ib qho kev sim tshuab siv los ntsuas qhov zoo ntawm qhov vuam.Cov kev ntsuam xyuas no txiav txim siab lub vuam lub peev xwm los tiv thaiv kev siv dag zog thiab nws cov kev tiv thaiv kom tawg.
  5. Macroscopic Examination:
    • Qhov tseem ceeb:Kev ntsuam xyuas macroscopic muab qhov ze-up ntawm qhov vuam cov qauv sab hauv.
    • Txheej txheem:Cov qauv ntu ntu ntawm cov vuam yog npaj thiab tshuaj xyuas nyob rau hauv lub tshuab ntsuas ntsuas los ntsuas cov qauv nplej, thaj chaw muaj kev kub ntxhov, thiab muaj qhov tsis xws luag lossis tsis zoo.
  6. Microscopic Examination:
    • Qhov tseem ceeb:Kev tshuaj xyuas microscopic muaj cov ntsiab lus zoo dua ntawm kev nthuav dav ntawm weld's microstructure.
    • Txheej txheem:Cov ntu nyias ntawm cov weld yog polished thiab soj ntsuam nyob rau hauv lub tshuab ntsuas hluav taws xob siab los ntsuas qhov vuam cov khoom siv hlau, suav nrog cov nplej loj, cov ntsiab lus suav nrog, thiab theem faib.
  7. Kev kuaj ultrasonic (UT):
    • Qhov tseem ceeb:UT muaj txiaj ntsig zoo hauv kev txheeb xyuas qhov tsis xws luag hauv qhov vuam.
    • Txheej txheem:Ultrasonic nthwv dej raug xa mus rau hauv cov vuam, thiab cov kev cuam tshuam tsis zoo raug tshuaj xyuas.Txhua yam tsis zoo hauv cov qauv weld raug txheeb xyuas raws li cov qauv ncha.
  8. Kev Ntsuas Hluav Taws Xob (RT):
    • Qhov tseem ceeb:RT muab kev pom dav dav ntawm qhov vuam qhov mob sab hauv.
    • Txheej txheem:X-rays los yog gamma rays tau dhau los ntawm kev sib txuas, tsim cov duab ntawm cov yeeb yaj kiab lossis cov cuab yeej digital.Discontinuities xws li voids, inclusions, los yog kab nrib pleb tshwm raws li duab ntxoov ntxoo ntawm lub xov tooj cua.

Kev tshuaj xyuas cov vuam zoo hauv cov tshuab vuam pob tw yog txheej txheem ntau yam uas siv ntau txoj hauv kev, suav nrog kev tshuaj xyuas qhov muag, kev kuaj xyuas qhov ntev, kev sim tsis muaj kev puas tsuaj, kev sim tshuab, kev kuaj macroscopic thiab microscopic, kuaj ultrasonic, thiab kuaj radiographic.Txhua yam ntawm cov txheej txheem no ua haujlwm rau lub hom phiaj tshwj xeeb hauv kev ntsuam xyuas qhov kev sib koom ua ke ntawm cov txheej txheem, lub suab sab hauv, thiab ua raws li cov qauv tsim.Los ntawm kev siv cov kev tshuaj xyuas no nruj me ntsis, cov vuam thiab cov neeg soj ntsuam tuaj yeem ua kom ntseeg tau tias cov pob qij txha welded ua tau raws li cov qauv kev lag luam thiab cov kev xav tau kev nyab xeeb, ua rau muaj kev vam meej tag nrho thiab kev ntseeg siab ntawm cov qauv welded hauv ntau daim ntawv thov.
