1.Kusarudzwa kwezvinhu uye kugadzira welding zvinoenderana neASME Boiler uye Pressure Vessel Code uye ANSI Pressure Pipeline Code.
2. Mushonga wekemikari wesimbi yezvikamu zvakasungirirwa uye zvinhu zvakasungirirwa zvinofanira kuenderana nezvinodiwa zvehutano.Iyo yekutanga zvinhu inofanirwa kuenderana neiyo ASTM tekinoroji zviga zvezvakakodzera zvinyorwa B165, B164, B127.filler zvinhu zvinofanirwa kuenderana neASME A-42 yekuzadza zvinhu kune yakatsanangurwa ER-NiCu-7 kana ER-ENiCu-4.
3. Iyo weld bevel uye nzvimbo yakapoteredza yetsvina (mafuta ester, firimu yemafuta, rust, nezvimwewo) inofanira kucheneswa nemhinduro yekuchenesa.
4. Kana tembiricha yehwaro zvinhu iri pasi pe0 ℃, inodiwa preheat kusvika 15.6-21 ℃, uye weld bevel yechinhu ichidziya kusvika 16-21 ℃ mukati me75mm.
5. The weld bevel prefabricated inonyanya kuenderana newelding chinzvimbo uye ukobvu hwezvinhu, Monel alloy inoda bevel angle ye weld pane zvimwe zvinhu, iyo yakagomara mupendero kupfuura zvimwe zvinhu kuve diki, kuti monel alloy plate ukobvu hwe3.2. -19mm, iyo bevel angle ndeye 40 ° angle ine blunt mupendero 1.6mm, mudzi gap we 2.4mm, isingasviki 3.2mm weld pamativi ese kuti achekwe kana kucheka zvishoma bevel, kwete kucheka bevel.Mativi e weld anotanga kugadzirwa nemichina nzira, kana dzimwe nzira dzakakodzera, dzakadai searc gas planing kana plasma cutting, arc cutting.Pasinei nzira, rutivi weld inofanira kuva yunifomu, yakatsetseka uye burr-isina, bevel harifaniri kuva slag, ngura uye tsvina inokuvadza, kana pane makatsemuka slag uye zvimwe kukanganisa zvinoda kukwenenzverwa uye ipapo kunyatsotariswa pamberi welding. .
6. Zvisungo zveukobvu hwemidziyo yevabereki, ukobvu hwezvinhu zvakakurudzirwa (4-23mm) kusvika 19mm inotenderwa weld, humwe hukobvu hunogonawo kuiswa weld asi hunoda kubatanidzwa kwechidimbu chakadzama.
7. Welding pamberi petsvimbo welding kuti uome kurapwa, kuomesa tembiricha kutonga pa230 - 261 C.
8. Welding mamiriro: pamusoro pezvikamu zvakasungirirwa hazvigoni kusungirirwa nekuda kwemvura uye unyoro, mazuva ekunaya, mazuva ane mhepo haakwanisi kuvhurika-mhepo welding, kunze kwekunge yakagadzika chidziviriro chekudzivirira.
9. Hapana kurapwa kwekupisa kunodiwa mushure mekugadzirisa.
10. Yakawanda yekugadzira tekinoroji ine simbi arc welding (SMAW), inogonawo kushandiswa gasi yakadzivirirwa tungsten arc welding (GTAW), otomatiki welding ndiyo.hazvikurudzirwe.Kana otomatiki welding ikashandiswa, ipapo argon arc welding, kushandiswa kwewelding tsvimbo haizungunuke welding process, kuitira kuti weld simbi fluidity ishande, inogona kutenderedza zvishoma kubatsira kuyerera kwesimbi weld, asi iyo yakanyanya swing upamhi inoita. usapfuure zvakapetwa kaviri dhayamita yetsvimbo yewelding, pakushandiswa kweSMAW nzira yewelding iri nyoreparameters ndeiyi:Simba rekushandisa: yakananga, reverse kubatana, kushanda kwakashataVoltge: 18-20VCurrent: 50 - 60AElectrode: kazhinji φ2.4mm ENiCu-4 (Monel 190) electrode
11. Spot welding inofanira kusanganiswa pamudzi we weld channel.
12. Mushure mokunge weld yakaumbwa, hapana muganhu unobvumirwa kuvapo.
13. Iyo butt weld inofanira kusimbiswa, kureba kwekusimbisa hakufaniri kuva pasi pe 1.6mm uye kwete kupfuura 3.2mm, iyo fungidziro haifaniri kunge inopfuura 3.2mm, uye kwete kupfuura 3.2mm yepombi bevel.
14. Mushure mekugadzira chidimbu chega chega che weld, inofanira kuva weld flux uye kunamatira nesimbi isina tsvina yewaya bhurasho kuti ibvise yakachena, isati yave welding rinotevera.
15. Kugadzirisa kukanganisa: Kana kunaka kwedambudziko re weld, kushandiswa kwekukuya uye kucheka kana arc gasi kuchacherwa kunze kwekuremara kusvikira ruvara rwesimbi rwepakutanga, uyezve-welded maererano nemaitiro ekutanga ekugadzira uye zvigadzirwa zveunyanzvi, usaite. bvumira nzira yekusando kuvhara iyo weld metal cavity kana kuzadza gomba nezvinhu zvekunze.
16. Carbon simbi overlay welding Monel alloy ichashandisa p2.4mm welding rod, nekuti iyo welded Monel alloy layer inofanira kunge iine 5mm gobvu, kuitira kudzivirira kutsemuka, inofanira kukamurwa kuita maviri akaturikidzana ewelding.Yekutanga layer ndeye shanduko yeMonel alloy yakasanganiswa nekabhoni simbi.Chikamu chechipiri pamusoro peiyo yakachena Monel alloy layer, mushure mekugadzirisa kuti ive nechokwadi chekuti kune yakachena Monel alloy inoshanda ukobvu layer ye3.2mm, imwe neimwe yakashongedzerwa dhiri kuti itonhodzerwe kusvika kune tembiricha yekamuri, nesimbi isina tsvina yewaya bhurashi kuti ibvise welding flux isati yaiswa. pane imwe layer.
17. Hukobvu kupfuura 6.35 mm Monel alloy ndiro, butt welding kuti kupatsanurwa kuita mana kana kupfuura akaturikidzana welding.Iwo matatu ekutanga akaturikidzana anowanikwa yakanaka welding tsvimbo (φ2.4mm) welding, mashoma ekupedzisira akaturikidzana aripo coarse welding tsvimbo (φ3.2mm) welding.
18. Monel alloy welding pakati peAWS ENiCu-4 welding tsvimbo ER NiCu-7 waya, carbon steel uye Monel alloy welding ne EN NiCu-1 kana EN iCu-2 welding tsvimbo zvimwe zvigadziro uye zvakafanana nemashoko ari pamusoro apa.
kuzvidzora kwehutano
Kuti ive nechokwadi chemhando yewelding, isingaparadze nzira dzekuyedza nzira dzekuongorora zvinoreva kudzora mhando, senge radiation, magineti particle, ultrasonic, kupinda uye dzimwe nzira dzekuongorora dzekuongorora.Welds yose inofanirawo kuongororwa nokuda kwekuremara kwechitarisiko, zvakadai sekuputika kwepamusoro, kuruma, kurongeka uye kupinda mukati, nezvimwewo. Panguva imwecheteyo, rudzi rwekushongedza, weld forming inofanirawo kuongororwa.Midzi yose inosungirirwa inofanira kuongororwa kuti inoiswa ruvara, uye kana pakakanganisika, inofanira kugadzirwa patsva isati yaongororwa.
