Kev Tshuaj Xyuas Qhov Tsis Zoo Ntawm Qhov Chaw Thiab Qhov Zoo Sab Hauv Ntawm Cov Hlau Welds

Kev tshuaj xyuas hlau vuam yog hais txog cov txheej txheem ntawm kev ntsuam xyuas qhov zoo ntawm cov pob qij txha vuam los ntawm kev siv ntau yam thev naus laus zis kuaj. Kev tshuaj xyuas qhov zoo ntawm vuam yog qhov txuas tseem ceeb los xyuas kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov qauv engineering. Hauv qab no, cov ntsiab lus tseem ceeb ntawm kev tshuaj xyuas qhov zoo ntawm vuam tau piav qhia los ntawm qhov ntev ntawm kev tshuaj xyuas pom, kev sim khoom siv kho tshuab, thiab kev tshuaj xyuas macroscopic & microscopic.

1.Kev Tshuaj Xyuas Pom (Lub Tshuab Ntsuas Cov Khoom Sib Nqus)

Ua kev tshuaj xyuas pom kom paub tseeb tias qhov chaw vuam puas muaj qhov tsis zoo xws li tawg, qhov cua, cov pob zeb slag, thiab kev sib xyaw tsis tiav; ntsuas qhov ntev xws li dav, qhov siab, kev txhawb nqa vuam, thiab kev tsis sib haum xeeb kom ntseeg tau tias ua raws li cov qauv tsim. Lub caij no, siv lub tshuab ntsuas sib nqus los nrhiav qhov tsis zoo ntawm qhov chaw thiab ze ntawm qhov chaw hauv cov ntaub ntawv ferromagnetic, siv cov neeg sawv cev kuaj nkag mus los txheeb xyuas qhov tsis zoo ntawm qhov chaw (piv txwv li, qhov cua, cov kab nrib pleb) hauv cov ntaub ntawv tsis muaj qhov, siv lub tshuab ntsuas tuab ultrasonic los sim kev txhawb nqa vuam, cov hlau hauv paus nyias lossis cov tsis zoo sab hauv, thiab siv lub tshuab ntsuas qhov roughness ntawm qhov chaw vuam los ntsuas seb qhov zoo ntawm qhov chaw ntawm cov vuam hauv av puas ua tau raws li cov qauv.

2.Kev Tshawb Fawb Macroscopic thiab Microscopic (Optical Penetration Depth Microscope thiab Metallographic Microscope)

Kev kuaj xyuas macroscopic suav nrog kev siv lub tshuab microscope los saib xyuas cov yam ntxwv ntawm cov cheeb tsam xws li thaj chaw sib txuas weld thiab thaj chaw kub. Nws muaj kev ua haujlwm yooj yim thiab tuaj yeem txheeb xyuas cov qhov tsis zoo ntawm cov vuam, ua rau nws tsim nyog rau kev tshuaj xyuas ua ntej ntawm cov khoom loj.

Kev kuaj xyuas lub tshuab microscopic suav nrog kev saib xyuas cov qauv me me ntawm cov vuam siv lub tshuab microscope metallographic los ntsuas qhov zoo ntawm kev vuam thiab qhov loj ntawm thaj chaw raug cua sov. Nws kuj tseem kuaj xyuas seb puas muaj qhov tsis zoo xws li kub dhau thiab kub hnyiab.

3.Kev Ntsuas Khoom Siv Kho Tshuab (Lub Tshuab Ntsuas Tensile thiab Vickers Hardness Tester)

Kev ntsuam xyuas cov khoom siv kho tshuab ntsuas qhov ua tau zoo ntawm kev vuam los ntawm kev ntsuam xyuas tensile (rau kev ntsuas lub zog thiab plasticity), kev ntsuam xyuas khoov (rau kev txheeb xyuas plasticity thiab toughness), kev ntsuam xyuas kev cuam tshuam (rau kev ntsuas qhov cuam tshuam toughness), thiab kev ntsuam xyuas hardness (rau kev ntsuas qhov faib hardness).

Thaum lub sijhawm vuam, cov hlau puag, cov hlau vuam thiab thaj chaw kub-cuam tshuam dhau los ntawm lub voj voog thermal nyuaj, ua rau muaj kev hloov pauv tseem ceeb hauv microstructure thiab tom qab ntawd tsim cov cheeb tsam nrog kev faib tawm tsis sib xws. Los ntawm Vickers hardness testing, qhov nyuaj gradient ntawm txhua cheeb tsam ntawm qhov sib koom ua ke tuaj yeem ntsuas tau raws li qhov tseeb, uas muab lub hauv paus kev tshawb fawb rau kev ua kom zoo dua qub, kev tswj hwm zoo thiab kev tshuaj xyuas qhov tsis ua haujlwm.

4. Kev Tshawb Nrhiav Qhov Tsis Zoo Sab Hauv Ultrasonic (Kev Tshawb Nrhiav Qhov Tsis Zoo thiab Kev Ntsuas Qhov Hnyav)

Cov cuab yeej ntsuas qhov tsis zoo ntawm ultrasonic thiab cov ntsuas tuab ultrasonic yog siv los tshuaj xyuas cov qhov tsis zoo sab hauv xws li cov kab nrib pleb thiab cov slag suav nrog.
