Stainless hlau welding soj ntsuam cov ntsiab lus suav nrog los ntawm kev kos duab tsim rau cov khoom siv stainless hlau tawm ntawm tag nrho cov txheej txheem ntawm cov khoom siv, cov cuab yeej, cov cuab yeej, cov txheej txheem thiab cov khoom tiav tiav kev soj ntsuam, muab faib ua peb theem: kev tshuaj xyuas ua ntej vuam, vuam txheej txheem tshuaj xyuas, tom qab- weld soj ntsuam ntawm cov khoom tiav.Kev tshuaj xyuas cov txheej txheem tuaj yeem muab faib ua kev kuaj kev puas tsuaj thiab tsis muaj kev puas tsuaj rau kev tshawb nrhiav raws li qhov kev puas tsuaj los ntawm cov khoom tuaj yeem muab faib ua ob pawg.
1.Stainless hlau pre-weld soj ntsuam
Kev tshuaj xyuas ua ntej vuam suav nrog kev tshuaj xyuas cov khoom siv raw (xws li cov khoom siv hauv paus, vuam rods, flux, thiab lwm yam) thiab kev tshuaj xyuas cov qauv vuam tsim.
2.Stainless hlau vuam txheej txheem tshuaj xyuas
Xws li cov txheej txheem vuam kev soj ntsuam xyuas, kev tshuaj xyuas qhov loj me, kev sib dhos thiab kev soj ntsuam zoo ntawm kev sib dhos.
3.Stainless hlau welded tiav cov khoom soj ntsuam
Muaj ntau txoj hauv kev ntawm kev tshuaj xyuas tom qab vuam tiav, feem ntau siv yog cov hauv qab no:
(1)Kev tshuaj xyuas qhov tshwm sim
Kev soj ntsuam ntawm cov pob qij txha welded yog ib qho yooj yim thiab dav siv txoj kev tshuaj xyuas, yog ib feem tseem ceeb ntawm kev soj ntsuam cov khoom tiav, feem ntau yog nrhiav qhov tsis xws luag ntawm qhov chaw vuam thiab qhov loj ntawm qhov sib txawv.Feem ntau los ntawm kev soj ntsuam pom, nrog kev pab los ntawm cov qauv qauv, ntsuas thiab ntsuas tsom iav thiab lwm yam cuab yeej rau kev tshuaj xyuas.Yog hais tias muaj qhov tsis xws luag ntawm qhov chaw ntawm lub vuam, nws muaj peev xwm ua rau muaj qhov tsis xws luag hauv qhov vuam.
(2)Tightness kuaj
Kev khaws cov kua los yog roj hauv lub thawv welded, lub vuam tsis muaj qhov tsis zoo, xws li nkag mus rau cov kab nrib pleb, qhov pores, slag, tsis welded los ntawm thiab xoob cov ntaub so ntswg, thiab lwm yam, tuaj yeem siv los nrhiav kev ntsuas nruj.Txoj kev ntsuas nruj yog: ntsuas paraffin, ntsuas dej, ntsuas dej ntws tawm.
(3)Kev ntsuas lub zog ntawm lub nkoj siab
Lub nkoj siab, ntxiv rau qhov kev sim sealing, tab sis kuj rau kev kuaj lub zog.Feem ntau, muaj ob hom kev ntsuas dej siab thiab ntsuas cua siab.Lawv tuaj yeem kuaj hauv lub siab ntawm kev ua haujlwm ntawm lub thawv thiab cov raj xa dej weld nruj.Kev ntsuas pneumatic yog qhov rhiab heev thiab nrawm dua li qhov kev sim hydraulic, thaum cov khoom tom qab qhov kev sim tsis tas yuav tsum tau ntws tawm, tshwj xeeb tshaj yog rau cov khoom uas muaj dej tsis zoo.Txawm li cas los xij, qhov txaus ntshai ntawm qhov kev xeem yog ntau dua li qhov kev sim hydraulic.Thaum ua tiav qhov kev xeem, yuav tsum ua raws li cov kev ntsuas kev nyab xeeb uas tsim nyog los tiv thaiv kev sib tsoo thaum lub sijhawm kuaj.
(4)Lub cev txoj kev sim
Txoj kev tshuaj xyuas lub cev yog siv qee qhov tshwm sim ntawm lub cev rau kev ntsuas lossis kev tshuaj xyuas.Cov khoom siv lossis cov khoom ua haujlwm hauv kev kuaj xyuas qhov tsis xws luag, feem ntau yog siv txoj kev kuaj xyuas qhov tsis zoo.Tam sim no tsis muaj kev puas tsuaj tsis pom kev ultrasonic qhov tsis pom kev, pom qhov tsis pom kev, kev nkag mus rau hauv kev tshawb nrhiav, sib nqus qhov tsis zoo.
① Ray Detection
Ray flaw detection yog kev siv hluav taws xob tuaj yeem nkag mus rau hauv cov khoom siv thiab hauv cov khoom muaj cov yam ntxwv ntawm attenuation kom pom qhov tsis xws luag hauv txoj kev kuaj pom qhov tsis zoo.Raws li qhov sib txawv rays siv nyob rau hauv flaw detection, yuav muab faib ua X-ray flaw detection, γ-ray flaw detection, high-zog hluav taws xob teeb pom kev zoo.Vim tias nws txoj kev qhia qhov tsis xws luag yog qhov sib txawv, txhua qhov kev kuaj pom hluav taws xob tau muab faib ua ionisation txoj kev, fluorescent screen soj ntsuam txoj kev, txoj kev yees duab thiab kev lag luam hauv TV.Ray soj ntsuam yog tsuas yog siv los kuaj cov weld sab hauv cov kab nrib pleb, unwelded, porosity, slag thiab lwm yam tsis xws luag.
②Ultrasonic flaw detection
Ultrasound nyob rau hauv cov hlau thiab lwm yam niaj hnub tshaj tawm propagation, vim hais tias ntawm lub interface nyob rau hauv sib txawv xov xwm yuav tsim reflections, yog li nws yuav siv tau rau sab hauv tsis xws luag.Ultrasonic tshuaj xyuas ntawm txhua yam khoom siv vuam, ib feem ntawm qhov tsis xws luag, thiab tuaj yeem nkag siab ntau dua los nrhiav qhov chaw ntawm qhov tsis xws luag, tab sis qhov xwm txheej ntawm qhov tsis xws luag, cov duab thiab qhov loj me yog qhov nyuaj dua los txiav txim siab.Yog li ultrasonic flaw nrhiav tau feem ntau yog siv nrog rau kev soj ntsuam rays.
③ Kev soj ntsuam sib nqus
Kev soj ntsuam hlau nplaum yog siv cov hlau nplaum hlau nplaum ntawm ferromagnetic hlau qhov chaw uas tsim los ntawm cov hlau nplaum to kom pom qhov tsis xws luag.Raws li cov kev sib txawv ntawm kev ntsuas magnetic to, tuaj yeem muab faib ua magnetic hmoov txoj kev, magnetic induction method thiab magnetic recording method, nyob rau hauv uas cov magnetic hmoov txoj kev yog feem ntau lug siv.
Magnetic flaw detection tsuas tuaj yeem pom qhov tsis xws ntawm qhov chaw thiab ze ntawm qhov chaw ntawm cov hlau nplaum, thiab tsuas yog ua kom muaj nuj nqis ntawm qhov tsis xws luag, thiab qhov xwm txheej thiab qhov tob ntawm qhov tsis xws luag tsuas yog kwv yees raws li kev paub dhau los.
④ Kev xeem nkag
Kev ntsuas kev nkag mus yog siv cov permeability ntawm qee cov kua thiab lwm yam khoom siv lub cev los nrhiav thiab pom qhov tsis xws luag, suav nrog kev kuaj xim thiab fluorescence flaw detection ob, tuaj yeem siv los txheeb xyuas cov khoom ferromagnetic thiab non-ferromagnetic khoom defects.
Cov saum toj no yog cov khoom siv stainless hlau ua stainless hlau vuam tshuaj xyuas cov ntsiab lus suav nrog los ntawm kev kos duab tsim rau cov khoom siv stainless hlau tawm ntawm tag nrho cov txheej txheem ntawm stainless hlau vuam tshuaj xyuas txoj kev thiab cov lus qhia.
