Nws yuav tsum tau paub tias tsis muaj vuam feem ntau yog hais txog cov txheej txheem ntawm vuam cov pob qij txha uas tsis welded thaum lub sij hawm vuam. Tsis siv vuam vuam tuaj yeem ua rau muaj kev sib tsoo zoo. Cov laj thawj rau vuam yuam kev feem ntau suav nrog cov hauv qab no. Tej zaum nws yuav yog qhov tam sim no siab dhau lawm thiab melts los yog tam sim no me me dhau los weld. Tsuas yog kho qhov tsim nyog tam sim no; nws yuav yog tias sab laug thiab sab xis ntawm rab phom vuam tsis sib haum lossis txoj haujlwm ntawm rab phom vuam yog siab dhau. Tus tswv hloov kho tuaj yeem ua raws li rab phom vuam; Nws yuav yog tias tsis muaj argon roj thiab cov nplaim vuam tsis muaj zog, tsuas yog hloov cov roj argon; nws yuav yog cov pwm thiab cov hlau tsis muaj dej los yog roj, ua rau cov nplaim hluav taws xob sib txuas tsis sib xws, siv Tina dej Nws yuav tsis muaj teeb meem los ntxuav cov hlau siv nrog turpentine, turpentine lossis toluene. Tau kawg, muaj lwm yam uas ua rau 316 stainless hlau kav tsis tuaj yeem welds.
Tsis tas li ntawd, kev tiv thaiv kev tiv thaiv yuav tsum tau ua kom nce qhov kev soj ntsuam zoo thiab nce qhov zaus ntawm kev soj ntsuam zaum kawg kom tsis txhob plam vuam thiab vuam khoob, thiab cov khoom tsis tsim nyog yuav tsis raug xa mus rau cov txheej txheem tom ntej. Yog li ntawd, nws yog ib qho tsim nyog yuav tau siv qee txoj hauv kev los kuaj xyuas cov dej xau.
Txhawm rau txheeb xyuas seb puas muaj cov xau hauv hluav taws xob vuam ntawm 316 stainless hlau kav, kev tshuaj xyuas xim tuaj yeem siv. Kev tshuaj xyuas xim yog ib txoj kev kuaj tsis muaj kev puas tsuaj. Nws yog ib txoj kev tshuaj xyuas saum npoo feem ntau yog siv los txheeb xyuas qhov kev puas tsuaj ntawm qhov chaw xws li cov kab nrib pleb uas tsis tuaj yeem lees paub los ntawm qhov muag liab qab, xws li kuaj pom qhov ze ntawm qhov tsis xws luag (kav), qhov pores, porosity thiab kev sib cais ntawm 316 steel kav, qhov tsis xws luag xws li txheej txheej, tsis muaj permeability thiab Tsis muaj fusion (tseem hu ua PT test). Nws yog qhov tsim nyog rau kev tshuaj xyuas cov khoom siv hlau ntom ntom (welds), cov ntaub ntawv tsis yog xim hlau thiab qhov tsis xws luag (kav, qhov, thiab lwm yam) ntawm cov khoom nto.
Lub hauv paus ntsiab lus ntawm cov xim penetrant flaw detection agents: siv cov xim los npog cov khoom nto, thiab tom qab ntawd cov xim nkag mus rau hauv qhov puas. Tom qab qee lub sij hawm, yaug cov xim tawm ntawm qhov chaw. Siv tus tsim tawm mus rau qhov chaw tsim. Qhov kev puas tsuaj ntawm 316 stainless hlau yeeb nkab tuaj yeem pom meej vim tias cov xim tau nkag mus rau hauv nws.
Infrared to detection cov cuab yeej feem ntau yog siv los txheeb xyuas qhov to. Infrared solder leak detection yog ib qho kev ntsuam xyuas uas tsis muaj kev puas tsuaj uas siv ib txoj hauv kev los ntsuas cov hluav taws xob infrared ntawm cov khoom kom tau txais qhov kub thiab txias ntawm qhov chaw los txiav txim seb puas muaj kev puas tsuaj sab hauv hauv lub xeev ua haujlwm. Yog tias qhov vuam raug pom tias ploj lawm, cov cuab yeej yuav tshaj tawm cov lus ceeb toom, thiab lub tshuab tsim khoom yuav txiav tawm 316 stainless hlau yeeb nkab sib raug rau lub tswb kom tiv thaiv cov yeeb nkab uas ploj lawm los ntawm cov txheej txheem tom ntej.
Cov lus saum toj no yog cov ntsiab lus ntawm qhov ua rau thiab kev tshawb nrhiav txoj hauv kev ntawm kev xau vuam ntawm 316 stainless hlau kav. Muaj ntau ntau qhov laj thawj rau qhov tsis muaj vuam, thiab nws yog ib qho nyuaj rau kev txiav txim siab qhov twg, thiab kev tiv thaiv yuav tsum tau ua. Txhawm rau txheeb xyuas seb cov kav dej puas ploj lawm, koj tuaj yeem siv cov xim tsis pom kev thiab cov khoom siv infrared leak weld nrhiav kom pom. Kev vuam ploj yuav ua rau qee yam kev lag luam poob thiab pov tseg. Yog li ntawd, kev soj ntsuam vuam seam yuav tsum tau ua nyob rau ntawm 316 stainless hlau kav los tiv thaiv cov vuam uas ploj lawm thiab tsis tiav kev nkag mus ntawm cov kav welded.
