NEXT, NMACHO Tehc (Seko Machinery) icharamba ichikutora kuti unzwisise matambudziko anogona kuitika panguva yekuita uye kukubatsira iwe kudzivirira uye kugadzirisa matambudziko akadaro.
03 Welding inopisa marara (crystallization marara muWels, liqueffaction marara munzvimbo inopisa-yakakanganiswa)
Kunzwa kwekunzwa kwekupaza kwekupaza zvakanyanya kunoenderana nemakemikari kuumbwa, kurongeka uye kuita kwechinyorwa. Ni iri nyore kuumba yakadzika melting point makomputa kana eutectic neisina tsvina senge s uye p. P. Kureba kweBoron uye silicon ichakurudzira kupaza kwehasha.
Iyo weld seam iri nyore kuumba columnar crystal chimiro chine simba, iyo inokodzera kusekerera kwekukuvadza uye zvinhu. Izvi zvinosimudzira kuumbwa kweiyo inoenderera mberi yekunyepedzera mvura firimu uye inovandudza pfungwa yekunzwa kwekuparadza kwekupaza. Kana iyo testing isina kufanana, zviri nyore kuumba yakakura kushushikana uye kusimudzira chizvarwa chekupisa kupisa marara.
Maitiro ekudzivirira:
a. Kudzora zvakanyatso kudzora zvirimo zvekukuvadza kusviba kweS uye P.
b. Gadzirisa sangano reSimbi weld. Chiverengero cheshuwa chine weld ine yakanaka yekupenga kuramba. Iyo Delta Phase muWeld inogona kunatsa zviyo, Bvisa nzira yeiyo Onse Austenite, uye chidimbu cheDelta chinogona kuderedza simba rezvakanaka
c. Rongedza iyo Weld Simbi Alloy Kuumbwa. Zvakakodzera kuwedzera zvirimo zveMN, C, uye n mune imwechete-phase yeiyo trace's trace
d. Maitiro matanho. Kuderedza kufararira kwedziva rakanyungudutswa kudzivirira kuumbwa kwemakristasi akakora. Shandisa zvidiki zvekupisa kupisa uye chidiki chivharo-chikamu cheld bhead. An ARC STBILITIZIZISI YAKABVUNZWA PAKUTI KUTI VADZIDZE KUTI VANYENGETSE YENYAYA YEMAHARA, Vandudza kushanda kwekushanda kwepfuti inotsvedza, uye kuvandudza hunhu hunotyisa.
Semuenzaniso, 25-20 Austenitic Simbi iri prode kune liquefaction marara. Izvo zvinokwanisika kuganhurira zvakanyanyisa kusvibiswa uye kukura kwetsika zvezvinyorwa, kutora yakakwira-simba density tuling nzira, diki kupisa kupisa uye kuwedzera chiyero chinotonhorera chejoini.
04 embrilement yeakadzika majoini
Kupisa-simba simbi inofanirwa kuve nechokwadi chekuti plasticity yeayo yakavezwa majoini ekudzivirira yakakwirira-tembiricha yembbrittlement; Low-tembiricha inodikanwa kuti uve neakanaka-kupisa-tembiricha yekudziya kudzivisa yakaderera-tembiricha brautlet bracture yeakadzika majoini.
05 Huru Hombe Kukanganisa
Nekuda kweiyo yakaderera inodanana neyakaderera uye yakakura yekuwedzera coefficient, kusvibisa kwehutachikuru kwakakura, uye clamps inogona kushandiswa kudzivirira kudzikisira. Iyo Welding nzira yeAustenitic Stainless Simbi uye kusarudzwa kweWalding zvinhu:
Austenitic Stainless Steel inogona kuunganidzwa neArgon Tungsten arc Welding (Tig), Molt
Austenitic Stainless Simbi ine yakaderera-yakadzika zvazvino nekuda kwekusiya kwayo yekunyungudika yekunyungudika, yakaderera inobata, uye yemagetsi emagetsi ekupokana. Tete Welds uye mabheji anofanirwa kushandiswa kuderedza yakakwira nguva yekugara, kudzivirira carbide precipitation, kuderedza weld shrinkage kushushikana, uye kuderedza kupaza kupaza kupaza kwekunzwa.
Kuumbwa kwezvinhu zvakasikwa, kunyanya cr uye ni yekupa zvinhu zvakakwirira, zvakakwirira kupfuura izvo zvezvinyorwa zvebase. Shandisa midziyo yehutachiona iine mari shoma (4-12%) yeFerrite yekuve nechokwadi chekupaza kupokana (kutonhora kupaza, kupisa kupaza, kushushikana crosing) kuita kweWelks.
Kana chikamu cheshuwa chisiri chinotenderwa kana kusakwanisa muWelk, iyo testing zvinhu inofanira kunge iri manyorerwo zvinhu zvine mo, mn uye zvimwe zvinhu zvezvigadzirwa.
Iyo c, s, p, s, si, nb muzvinyorwa zvekutungamira zvinofanirwa kunge zvakaderera sezvinobvira. NB ichakonzera kusimbisa marara mune yakachena Austenitic weld, asi chidiki chidiki chesimbi muWeld inogona kudzivirirwa.
Zvekutengesa zvivakwa zvinoda kudzikiswa kana kushushikana-kusunungurwa mushure mekusunungurwa, NB-ine midziyo yeWelding inowanzoshandiswa. Yakanyungudika Arc Welding inoshandiswa kuWeld iyo yepakati ndiro, uye kurasikirwa kwekupisa kweCr uye ni kunogona kuwedzerwa neshanduko yeiyo flux uye iyo alloy zvinhu mu waya weCarding;
Nekuda kwekupaza kukuru kwakadzika, kutarisira kunofanirwa kutorwa kuti udzivise kuitika kwemarara anopisa pakati peiyo yeld uye kuderedzwa kweiyo corrosion kuramba munzvimbo inopisa. Kutarisirwa kunofanirwa kubhadharwa kuti usarudze akaomeswa waya waya uye madiki madiki ekupisa kupisa. Walding Waling Wire inofanirwa kunge yakaderera muSI, S, uye P.
Iyo ferrite zvirimo mune kupisa-kupesana nestinless simbi yeld haifanirwe kupfuura 5%. ZveAustenitic Stainless Steel neCr uye NICLE yakakura kupfuura 20%, yakakura mn (6-8%) Yakatemwa flux inofanira kudzivirira kuwedzera kweiyo kune iyo Weld uye inovandudza kupaza kwayo kupokana.
Iyo Special Flux yeAustenitic Simbi ine zvishoma kwazvo yeSi, iyo inogona kuendesa iyo Alloy yekuwedzera uye yekutsiva kurasikirwa kwezvinhu zveAlloy kusangana nezvinodiwa zveWelks nekuumbwa kwemakemikari.
