Iyo welding yemapombi esimbi isina tsvina kazhinji ine midzi welding, kuzadza welding uye kuvhara welding. Pazasi welding yestainless simbi pombi ndiyo inonyanya kukosha yestainless simbi pombi welding. Haisi kungobatana chete nehutano hwepurojekiti, asiwo ine chokuita nekufambira mberi kweprojekti. Parizvino, iyo yekumashure welding yesimbi isina tsvina pombi yakakamurwa kuita maviri maitiro: kumashure-kuzadza uye kwete-argon kuzadza. Argon-yakazadzwa kumashure kudzivirira yakakamurwa kuita yakasimba waya + TIG maitiro uye yakasimba waya + TIG + mvura-inonyungudika mapepa maitiro; kumashure isina argon-yakazadzwa dziviriro yakakamurwa kuita flux-cored waya inotsigira uye welding tsvimbo (yakavharwa waya) inotsigira TIG welding.
Iyo yepasi welding yesimbi isina simbi inowanzo tora iyo TIG maitiro. Zvinoenderana nemamiriro chaiwo pane saiti, tinogona kushandisa nzira ina dzinotevera dzepasi welding.
01. Nzira yekuvhara mhepo nekudzivirira nekushandisa kuvhara mabhodhi kumashure (kureva, yakasimba welding wire + TIG)
Kana iyo pombi yesimbi isina tsvina yakagadziridzwa, iyo welding yekubatanidza inogona kazhinji kutenderedzwa uye kusungirirwa, uye kufefetera kuri nyore kwazvo. Panguva ino, chivharo cheplate chinowanzo shandiswa kuvharira uye kufefetera mativi ese ari maviri ejointi yewelding mupombi kuchengetedza pasi welding, uye panguva imwecheteyo, rutivi rwekunze rwakavharwa nemucheka wekunamira. blockage.
Kana welding, maitiro ekufambisa mberi uye kumisa gasi gare gare inofanira kugamuchirwa. Iro jira rekunamira rekunze rinobvarurwa paunenge welding. Sezvo ndiro inovharira inoumbwa nerabha uye chena simbi, hazvisi nyore kukuvadzwa, saka iyi nzira yewelding inogona kunyatso kuvimbisa mukati meiyo weld. Yakazadzwa ne argon gasi uye ive nechokwadi chekuchena kwayo, kuitira kuti inyatso kuve nechokwadi chekuti simbi mukati meweld haina oxidized, uye ive nechokwadi chemhando yeweld backing.
02. Shandisa bepa rinonyungudika chete kana kusanganiswa kwepepa rinonyunguduka uye bhodhi rinovharira kuvharira uye kudzivirira kwemhepo (kureva tambo yakasimba welding + TIG + pepa rinonyungudika nemvura)
Kana iyo yakagadziriswa chiteshi chepombi yesimbi isina tsvina yakaiswa uye yakasungirirwa, zvakaoma kupinza mukati memukati, uye mamwe mativi ari nyore kuvhara. Muchiitiko ichi, bepa rinonyungudika nemvura + blocking plate rinogona kushandiswa kuvhara. Ndiko kuti, rutivi rwuri nyore kufefetera uye rwuri nyore kubvisa rwakanamwa nebhodhi rinovharira, uye rutivi rusiri nyore kufefetera uye rwakaoma kubvisa bhodhi rinovharira rakavharwa nepepa rinonyungudika nemvura.
Paunenge uchiputira simbi isina tsvina yakagadziriswa port, muzviitiko zvakawanda, hapazovi nemhepo inofefetera pamativi ese e weld. Panguva ino, maitiro ekuvimbisa kuchengetedzwa kweargon kuzadza mukati meweld inova dambudziko rakaoma. Muchivakwa chaicho panzvimbo, tinoshandisa mvura-soluble Nzira yekuisa chisimbiso nepepa, ventilating kubva pakati pe weld seam, uye kuisa kunze nemucheka wekunamatira zvakabudirira kugadzirisa matambudziko ari pamusoro.
Kana bepa rinonyungudika nemvura rinoshandiswa kuvhara mhepo, sezvo kufefetedza kunobva pakati pechisimbiso che weld, muchikamu chekupedzisira chekuisa chisimbiso, pombi yemhepo inofanira kuburitswa kunze nekukurumidza, uye argon yakasara mukati inofanira kushandiswa kudzivirira. uye pasi panofanira kukurumidza kupera uye muromo unofanira kunamwa.
Neiyi nzira, zvinofanirwa kucherechedzwa kuti pepa rinonyungudika nemvura rinofanira kunge rakapetwa kaviri, uye rinofanirwa kunamirwa zvakanaka, kana zvisina kudaro bepa rinonyungudika nemvura richakuvadzwa nyore nyore uye rinodonha, uye weld yemukati icharasikirwa nekudzivirirwa. argon gasi, uye oxidation ichaitika, zvichiita kuti weld igurwe uye ivhurwe zvakare. Welding haigone kuvimbisa kunaka kwewelding, asi zvakare inokanganisa zvakanyanya nguva yekuvaka, saka kuongororwa kwakasimba kunofanirwa kuitwa pamberi pekuisa, uye pepa rinonyungudika nemvura rinofanira kunamirwa.
Munzvimbo dzakawanda dzekuvaka, takatora nzira iyi yewelding yekutsigira, hutano hwayo hunogona kuvimbiswa zvinobudirira, uye zvakare yakaoma kuvaka, saka vanongwarira uye vane unyanzvi welders vanofanira kusarudzwa mubasa iri.
03. Rutivi rwekumashure haruna kudzivirirwa neargon gasi, uye iyo flux cored wire + TIG process inoshandiswa.
Iyi nzira yave ichishandiswa munyika yedu kwemakore akati wandei, uye flux-cored welding waya dzakadai E308T1-1, E308LT1-1, E309T1-1, E309LT1-1, 347T1-1, E316T1-1, E316LT1-1 dzakagadzirwa. , uye yakashandiswa mumunda The welding yakawana zviri nani zvehupfumi.
Sezvo rutivi rwemashure rusina kuzadzwa neargon, zvikomborero zvaro zviri pachena, zvakadai sekushanda kwepamusoro, nyore, uye mari shoma, uye yakakodzera kuiswa panzvimbo yekuvaka. Nekudaro, nekuda kwehunhu hwayo hwekuita, flux-cored welding waya ine zvakakwirira zvinodiwa kune welders panguva yekushanda. Waya yayo yekudyisa kumhanya inokurumidza uye iko kurongeka kwekudyisa waya kwakakwira, saka zvakaoma kugona. Mawelder anofanirwa kudzidziswa uye kuve nehunyanzvi vasati vatora chikamu mukukwesha. MuNanjing Yangba uye nzvimbo dzekune dzimwe nyika dzekuvaka, takabudirira kugadzirisa dambudziko rekuti argon haigone kufefeterwa pachiteshi chemusangano uye kugadzirisa chiteshi nekushandisa nzira iyi.
04. Rutivi rwekumashure haruna kudzivirirwa neargon gasi, uye iyo yakavharidzirwa welding wire (self-protected flux-cored welding wire) + TIG process inoshandiswa.
Mumakore ekuma1990, Kobelco nemamwe makambani emuJapan akagadzira waya dzepasi. Mumakore achangopfuura, nyika yangu yakagadzirawo Stainless simbi pasi welding waya (kureva, coated welding waya, akadai TGF308, TGF308L, TGF309, TGF316L, TGF347, etc.) isu takabudirira kushandisa nzira iyi mukuwedzera kwesimba uye shanduko chirongwa cheWupec.
Iyo nzira yekudzivirira yesimbi isina tsvina inotsigira waya + TIG maitiro ndeyekuti yekumashure weld inodzivirirwa nekuita kwesimbi pakati peiyo slag inogadzirwa neiyo welding waya inonyunguduka uye ayo alloy zvinhu, uye yekumberi weld inodzivirirwa neargon, slag uye alloy zvinhu. .
Paunenge uchishandisa maitiro aya, zvinotevera zvekushandisa zvinofanirwa kutariswa kune: Munguva yewelding process, iyo kona chaiyo pakati pechibatiso chewelding, welding wire uye welding piece inofanira kuchengetedzwa. Yakanaka kumashure kwekona yewelding handle nozzle ndeye 70 ° -80 °, The angle is 15 ° -20 °; nyatso kudzora tembiricha yedziva rakanyungudutswa, shandura tembiricha yedziva rakanyungudutswa nekushandura kona pakati pemubato welding uye weldment, kushandura kumhanya kwewelding, nezvimwewo, kuitira kuti uve nechokwadi chekuti weld shape yakanaka (hupamhi huripo. zvakafanana, hapana concave, Convexity uye zvimwe zvikanganiso);
Panguva yekushanda, ikozvino inofanira kuva yakakura zvishoma kudarika iyo yekubatanidza yakasimba core wire, uye mubato welding unofanira kuzununguswa zvishoma kuti ikurumidze kupatsanurwa kwesimbi yakanyungudutswa uye yakanyungudutswa yakanyungudutswa, iyo iri nyore pakucherechedza dziva rakanyungudutswa uye kutonga kana kupinda kuri. complete; paunenge uchizadza waya welding, zviri nani kuitumira kune 1/2 yedziva yakanyungudutswa, uye woidzvanya zvishoma mukati kuti uve nechokwadi chekupinda kwemidzi uye kudzivirira indentation;
Munguva yekugadzira, tambo yekutsvaira inofanira kudyiswa uye kutorwa kunze nguva dzose, uye tambo yekugadzira inofanira kugara iri pasi pekuchengetedzwa kweargon gasi, kuitira kudzivirira kupera kwetambo yekugadzira kubva kune oxidized uye kukanganisa kunaka kwekugadzira; Nzvimbo yewelding inofanira kudzika kusvika pakadzika dzika ye45 °, uye kutarisa kunofanira kubhadharwa kune zvakakanganiswa searc craters uye shrinkage cavities pakuvhara arc.
Yakavharwa welding waya inoshandiswa pazasi welding, uye argon gasi haishandiswe mukati meweld. Kushanda kweiyo welder iri nyore uye nekukurumidza, ine maitiro ekushanda kwepamusoro uye mutengo wakaderera. Iyi nzira inoshandiswa kubatanidza majoini makumi maviri nemasere uye majoini akagadziridzwa, uye chiyero chekupfuura chenguva imwe yekuona welding ndeye 100%), iyo yakakodzera kusimudzirwa kwedu uye kushandiswa.
Idzo dziri pamusoro ina Stainless simbi pasi welding nzira dzine zvadzo zvakanakira uye zvazvakaipira. Mukuvaka chaiko, isu hatifanire kufunga kwete chete mutengo wekuvaka, asiwo welding yemhando uye kufambira mberi kwekuvaka zvinoenderana nemamiriro chaiwo pane saiti, uye sarudza inonzwisisika nzira yekuvaka.
