Txoj kev thiab txheej txheem rau Weld Point Inspection nyob rau hauv nruab nrab-Frequency DC Spot Vuam Tshuab

Nyob rau hauv niaj hnub kev lag luam kev lag luam, kev siv nruab nrab-zaus ncaj qha tam sim no (DC) qhov chaw vuam tshuab yog dav vim lawv qhov ua tau zoo thiab qhov tseeb hauv kev tsim cov welds muaj zog thiab txhim khu kev qha. Txawm li cas los xij, ua kom ntseeg tau qhov zoo ntawm cov ntsiab lus weld yog qhov tseem ceeb tshaj plaws los lav cov qauv kev ncaj ncees thiab kev ua haujlwm ntawm cov khoom kawg. Kab lus no nthuav qhia cov txheej txheem dav dav thiab txheej txheem rau kev tshuaj xyuas cov ntsiab lus vuam hauv nruab nrab zaus DC qhov chaw vuam tshuab.

Medium-frequency DC qhov chaw vuam tshuab yog dav siv nyob rau hauv ntau yam lag luam rau lawv lub peev xwm los tsim cov welds zoo. Cov tshuab no tsim cov ntawv cog lus muaj zog thiab ruaj khov ntawm cov khoom siv hlau, ua rau lawv tseem ceeb hauv kev tsim tsheb, aerospace, thiab hluav taws xob tsim khoom. Yuav kom tswj tau qhov zoo ntawm vuam, nws yog ib qho tseem ceeb los tsim ib txoj kev tshuaj xyuas thiab txheej txheem. Kab lus no tham txog txoj hauv kev ua tau zoo thiab muaj txiaj ntsig kom ua tiav lub hom phiaj no.

Cov txheej txheem kev tshuaj xyuas qhov chaw weld tau teev tseg ntawm no ua ke nrog cov thev naus laus zis siab heev thiab txheej txheem txheej txheem kom ntseeg tau tias cov txiaj ntsig raug. Cov kauj ruam hauv qab no suav nrog:

1. Kev npaj:

• Pib los ntawm kev teeb tsa qhov nruab nrab zaus DC qhov chaw vuam tshuab thiab cov khoom ua haujlwm yuav tsum tau welded.
• Xyuas kom meej tias cov vuam tsis xws li tam sim no, qhov hluav taws xob, thiab qhov siab, raug ntsuas raws li qhov xav tau.

2. Vuam txheej txheem:

• Ua qhov chaw vuam txheej txheem raws li cov txheej txheem tsim. Cov kauj ruam no ua kom ntseeg tau tias cov ntsiab lus vuam raug tsim raws li cov qauv xav tau.

3. Kev tshuaj xyuas:

• Siv cov kev ntsuas tsis muaj kev puas tsuaj, xws li kuaj ultrasonic lossis X-ray tshuaj xyuas, txhawm rau ntsuas qhov ncaj ncees ntawm cov ntsiab lus vuam. Cov kauj ruam no yog ib qho tseem ceeb rau kev txheeb xyuas tej yam tsis xws luag lossis kev tsis txaus ntseeg.

4. Kev tshuaj xyuas:

• Tshawb xyuas cov txiaj ntsig tshuaj xyuas los txiav txim siab qhov zoo ntawm cov ntsiab lus weld. Yog tias pom muaj qhov tsis xws luag, ua qhov kho kom raug los kho lawv.

5. Cov ntaub ntawv:

• Khaws cov ntaub ntawv qhia ntxaws txog cov txheej txheem tshuaj xyuas, suav nrog cov kev siv tsis siv, kev tshuaj xyuas cov txiaj ntsig, thiab kev kho kom raug.

Hauv kev xaus, kom ntseeg tau qhov zoo ntawm cov ntsiab lus weld nyob rau hauv nruab nrab-frequency DC qhov chaw vuam tshuab yog qhov tseem ceeb rau kev tsim cov khoom ua tau zoo thiab txhim khu kev qha. Kab lus no tau muab ib txoj hauv kev thiab txheej txheem rau kev tshuaj xyuas cov ntsiab lus vuam, sib txuas ua ke, kev sib txuas, kev tshuaj xyuas, kev tshuaj xyuas, thiab cov ntaub ntawv theem. Los ntawm kev ua raws li cov lus qhia no, cov tuam txhab tsim khoom tuaj yeem txhim kho lawv cov khoom zoo thiab tswj kev ncaj ncees ntawm lawv cov welds, ua rau kom muaj kev nyab xeeb thiab ua tau zoo dua cov khoom kawg.
