Yuav ua li cas los txheeb xyuas qhov zoo ntawm lub pob tw welder?

1. Kev tshuaj xyuas qhov tshwm sim:
1. Kev soj ntsuam ncaj qha: Saib xyuas qhov chaw ntawm qhov sib txuas nrog lub qhov muag liab qab kom pom tias muaj qhov tsis xws luag, xws li tawg, qhov pores, slag inclusions, undercuts, weld pob, incomplete penetration, thiab lwm yam. Rau qee qhov me me, koj tuaj yeem ua tau. yuav tsum tau siv lub iav tsom iav (tsis pub ntau tshaj 20 zaug) los pab kev soj ntsuam.
2. Dimension ntsuas: Siv cov cuab yeej xws li vuam kev soj ntsuam xyuas los ntsuas seb qhov ntev ntawm qhov vuam, vuam pob, kev nyuaj siab, kev sib tsoo, thiab lwm yam raws li qhov yuav tsum tau ua. Nyob rau tib lub sijhawm, xyuas seb qhov vuam puas yog deformed.
2. Kev kuaj kev puas tsuaj:
1. Kev sim kua muag: kua muag, torsion, compression thiab lwm yam kev sim tau ua nyob rau ntawm qhov chaw los kuaj qhov chaw vuam core txoj kab uas hla, seam welding weld dav, sib koom ua ke cov yam ntxwv thiab kev ruaj ntseg ntawm vuam specifications.
2. Kev tshuaj xyuas lub zog qis: Los ntawm kev ua cov khoom kuaj macro (tsawg dua 100 zaug), soj ntsuam qhov kev nkag mus tsis tiav, overheating thiab oxide suav nrog cov ntsiab lus ntawm lub pob tw welded.
3. Kev ntsuas lub zog: suav nrog kev ntsuas qhov ntsuas qhov zoo, ntsuas kev sib tsoo, ntsuas torsion, ntsuas kev khoov, ntsuas kev qaug zog, thiab lwm yam., txhawm rau ntsuas lub zog, plasticity thiab cov yam ntxwv tawg ntawm qhov sib koom ua ke.
4. Metallographic thiab tshuaj muaj pes tsawg leeg tsom xam: Siv lub tshuab ntsuas metallographic los soj ntsuam cov kab nrib pleb sab hauv, shrinkage kab noj hniav, hwj txwv cov ntaub so ntswg qhov twg cov kab txuas txuas mus rau hauv cov kab weld, thiab lwm yam, thiab ua cov tshuaj muaj pes tsawg leeg tsom xam cov ntaub so ntswg weld, xoob shrinkage ntawm welds. , delamination thiab thermal tawg, burnout ntawm alloy ntsiab nyob rau hauv cov pob qij txha, cov ntsiab lus teeb meem nrog rau, thiab lwm yam.
3. Kev ntsuam xyuas tsis zoo:
1. X-ray tshuaj xyuas: Nws tuaj yeem kuaj xyuas qhov tsis xws luag xws li cov kab noj hniav shrinkage, qhov pores, cov kab nrib pleb hauv cov pob qij txha, thiab txaws (spot thiab seam welding) hauv qhov khoob ntawm daim hlau. Nyob rau tib lub sij hawm, rau welds nrog lub regional segregation, nws tseem tuaj yeem txheeb xyuas qhov loj ntawm cov nugget thiab qhov tsis zoo ntawm kev nkag mus tsis tiav.
2. Ultrasonic flaw detection: Nws tuaj yeem txiav txim siab qhov kev nkag mus tsis tiav (thaum muaj qhov sib txawv ntawm qhov chaw), qhov pores, shrinkage kab noj hniav thiab cov kab nrib pleb, thiab lwm yam, tab sis nws yog ib qho nyuaj rau kev ntes adhesion (kev nkag mus tsis tiav) vim lub thickness ntawm cov oxide. zaj duab xis uas tsim adhesion yog ntau me dua qhov loj uas tuaj yeem kuaj tau los ntawm kev kuaj xyuas qhov tsis zoo ntawm ultrasonic.
3. Eddy tam sim no flaw detection: Los ntawm kev sib piv cov tsim kev sib raug zoo ntawm txoj kab uas hla ntawm lub nugget thiab cov conductivity ntawm lub weld cheeb tsam, qhov luaj li cas ntawm cov nugget thiab qhov tsis xws luag ntawm incomplete penetration yuav raug soj ntsuam.
4. Sib nqus particle soj ntsuam: haum rau kev kuaj pom qhov tsis xws ntawm qhov chaw lossis ze ntawm cov khoom ferromagnetic. Lub welding yog magnetized nyob rau hauv ib tug muaj zog magnetic teb thiaj li hais tias cov magnetic kab ntawm quab yuam dhau los ntawm lub weld. Thaum ntsib qhov tsis xws luag ntawm qhov chaw vuam los yog ze ntawm qhov chaw, cov hlau nplaum sib nqus yog tsim los nyiam cov hlau nplaum hlau oxide hmoov sprinkled rau ntawm qhov chaw weld. Txoj hauj lwm thiab qhov loj ntawm qhov tsis xws luag tuaj yeem txiav txim siab raws li cov cim ntawm hlau hmoov adsorption.
5. Kev ntsuam xyuas Penetrant: feem ntau siv los xyuas qhov chaw qhib qhov tsis xws luag. Txau ib tug penetrant nrog fluorescent zas xim los yog xim liab rau ntawm qhov chaw ntawm lub vuam kom nkag mus rau hauv qhov tsis xws luag. Tom qab ntawd so lub npoo ntawm lub vuam kom huv si thiab siv ib txheej ntawm cov kua zaub dawb. Cov xim uas nkag mus rau hauv qhov tsis xws li vuam yog adsorbed los ntawm cov neeg saib dawb vim yog kev ua ntawm capillary, thiab cov kab liab ntawm qhov tsis xws luag tshwm rau ntawm qhov chaw.
4. Lwm txoj kev kuaj xyuas:
1. Surface contact resistance ntsuas: siv los ntsuas qhov zoo thiab conductivity ntawm weldment nto.
2. Kev ntsuas huab cua nruj sib koom ua ke: kuaj xyuas huab cua nruj ntawm qhov vuam. Rau qee qhov kev sib txuas uas xav tau kev sib khi, qee qhov siab ntawm cov pa roj lossis kua tuaj yeem sau rau hauv qhov vuam los xyuas seb puas muaj cov pa tawm.
3. Electron sojntsuam thiab electron microscope soj ntsuam: Cov txheej txheem no tuaj yeem muab cov ntaub ntawv ntau ntxiv ntawm cov qauv thiab cov ntaub ntawv sib xyaw rau kev tshuaj xyuas lub koom haum thiab kev ua haujlwm ntawm cov pob qij txha welded.
4. Kev tsom xam pob txha: Saib xyuas thiab txheeb xyuas qhov tawg ntawm cov pob qij txha welded kom nkag siab qhov ua rau thiab cov txheej txheem ntawm kev puas tsuaj, uas yuav pab ntsuas qhov vuam zoo.
