Copper welding
Nzira dzekugadzira mhangura (iyo inowanzonzi indasitiri yakachena mhangura) inosanganisira gasi welding, manual kabhoni arc welding, manual arc welding uye manual argon arc welding, uye zvimiro zvakakura zvinogonawo kuita automated welding.
1.Iyo inonyanya kushandiswa yemhangura yemhangura welding welding ndiyo inobatanidza butt, uye iyo inopindirana pamwe chete neT joint inofanira kushandiswa zvishoma sezvinobvira. Mhando mbiri dzewaya dzewelding dzinogona kushandiswa kugadzira gasi. Imwe iwaya yewelding ine deoxygenation elements, sewaya 201 ne202; imwe yacho iwaya yemhangura yakajairwa uye tambo yekucheka yezvinhu zvepasi, uye gasi mumiririri 301 inoshandiswa se flux. Neutral murazvo unofanira kushandiswa kana gasi welding mhangura.
2.Mhangura yemhangura yemhangura tsvimbo yemhangura yemhangura 107 inoshandiswa kune manual arc welding, uye welding core ndeyemhangura (T2, T3). Micheto yewelding inofanira kucheneswa isati yaiswa. Kana ukobvu hweweldment hwakakura kupfuura 4 mm, preheating inofanira kunge isati yapiswa isati yaiswa, uye tembiricha yekupisa inowanzoitika ku400 ~ 500 ℃. Kana welding nemhangura 107 welding tsvimbo, magetsi anofanirwa kudzoserwa neDC.
3.Short arcs inofanira kushandiswa panguva yekuputika, uye tsvimbo yekugadzira haifaniri kuzununguka yakatwasuka. Iyo welding tsvimbo inoita mutsara wekufamba unodzosera, izvo zvinogona kuvandudza kuumbwa kweweld. Iyo yakareba weld inofanira kuiswa zvishoma nezvishoma. Iyo welding yekumhanyisa inofanira kunge ichikurumidza sezvinobvira. Munguva ye-multi-layer welding, slag pakati pezvikamu inofanira kubviswa zvachose. Welding inofanira kuitwa munzvimbo inofefetera zvakanaka kudzivirira chepfu yemhangura. Mushure mekugadzira, shandisa sando-musoro-soro kuti ubate iyo weld kubvisa kushushikana uye kugadzirisa kunaka kweweld.
4.Manual argon arc welding yemhangura. Kana manual argon arc welding yemhangura, waya dzinoshandiswa iwaya 201 (special copper welding wire) newaya 202, uyewo shandisa waya yemhangura, yakadai seT2.
Usati waputira, iyo oxide firimu, mafuta uye imwe tsvina pamipendero yewelding yeworkpiece uye nepamusoro pewaya inofanira kucheneswa kuti irege kukanganisa senge pores uye slag inclusions. Nzira dzekuchenesa dzinosanganisira kuchenesa michina uye kuchenesa kemikari. Kana kukora kwebutt joint plate isingasviki 3 mm, bevel haina kuvhurwa; apo kukora kweplate kuri 3 kusvika 10 mm, bevel rakaita V rinovhurwa, uye bevel angle iri 60 kusvika 70; kana ukobvu hweplate hwakakura kupfuura 10 mm, bevel rakaita X rinovhurwa, Iyo bevel angle ndeye 60 ~ 70; kudzivirira isina kusungirirwa, mipendero yakagomara kazhinji inosiiwa. Zvinoenderana nehupamhi hweplate uye saizi yebevel, gaka regungano rejoint butt rinosarudzwa mukati meiyo 0.5 kusvika 1.5 mm.
Manual copper argon arc welding inowanzo shandisa DC positive connection, kureva kuti, tungsten electrode yakabatana kune negative electrode. Kuti ubvise maburi emhepo uye kuve nechokwadi chekubatana kwakavimbika uye kupinda kwemidzi ye weld, zvinodikanwa kuwedzera kumhanya kwewelding, kuderedza kushandiswa kweargon, uye preheat weldment. Kana kukora kweplate kuri pasi pe3 mm, tembiricha yekupisa iri 150 ~ 300 ℃; kana iyo hobvu yeplate yakakura kupfuura 3 mm, tembiricha yekupisa iri 350 ~ 500 ℃. Kupisa kwekutanga kwekushisa hakufaniri kunge kwakanyanyisa, kana zvisina kudaro maitiro emagetsi emajoini akasungwa achaderedzwa.
Kune zvakare mhangura kabhoni arc welding, uye maelectrodes anoshandiswa kunyorera kabhoni arc anosanganisira kabhoni essence electrodes uye graphite electrodes. Waya yewelding inoshandiswa kugadzira copper kabhoni arc welding yakangofanana neyekupisa gasi. Iyo yekutanga zvinhu inogona zvakare kushandiswa kucheka mitsetse, uye inoyerera yemhangura senge gasi mumiriri 301 inogona kushandiswa.
Brass welding
1.Nzira dzesimbi dzendarira dzinosanganisira: gas welding, carbon arc welding, manual arc welding uye argon arc welding. 1. Gasi welding yendarira Nemhaka yekuti kutonhora kwemoto wekugadzira gasi kwakaderera, zinc evaporation mumhangura panguva yekuputika ishoma pane kana uchishandisa magetsi welding, saka gasi welding ndiyo nzira inowanzoshandiswa mumhangura welding (ndinokutendai nekuteerera Dingding Automatic Welding).
Waya dzemagetsi dzinoshandiswa pakugadzira gasi rendarira dzinosanganisira: wire 221, wire 222 uye wire 224. Aya mawaya emagetsi ane zvinhu zvakadai sesilicon, tin, iron, nezvimwewo, izvo zvinogona kudzivirira uye kuderedza kubuda uye kupisa kwe zinc mumudziva wakaumbwa, uye inobatsira pakuita kuti weld igare. Kuita uye kudzivirira maburi emhepo. Fluxes inowanzo shandiswa mugasi welding brass inosanganisira hupfu hwakasimba uye gasi flux. Kuyerera kwegasi kunosanganisira boric acid methyl mafuta uye methanol; fluxes akadai segasi mumiririri 301.
2.Manual arc welding yendarira Pamusoro pemhangura 227 nemhangura 237, matanda ekugadzira pamba anogona kushandiswawo kugadzira ndarira.
Kana brass arc welding, iyo DC magetsi inopa yakanaka yekubatanidza nzira inofanirwa kushandiswa uye welding tsvimbo inofanirwa kubatanidzwa kune yakaipa electrode. Pamusoro peiyo weldment inofanira kucheneswa zvakanyatsonaka pamberi pekuisa. Iyo bevel angle haifanire kunge iri pasi pe60 ~ 70o. Kuti uvandudze kuumbwa kwe weld, zvikamu zvakasungwa zvinofanirwa kupiswa pa150 ~ 250 ℃. Ipfupi arc welding inofanirwa kushandiswa panguva yekushanda, isina yakatwasuka kana kumberi uye kumashure kuzungunuka, chete mutsara kufamba, uye kumhanya kwewelding kunofanirwa kunge kwakakwira. Brass welded parts inosangana necorrosive media senge mvura yegungwa neammonia inofanirwa kuvharirwa mushure mewelding kuti ibvise kushushikana kwewelding.
3.Manual argon arc welding yendarira. Manual argon arc welding yendarira inogona kushandisa yakajairwa waya dzendarira: waya 221, waya 222 uye waya 224, uye zvinhu zvine zvinhu zvakafanana neiyo base zvinhu zvinogona zvakare kushandiswa semazadza zvinhu.
Welding inogona kuitwa neyakananga ikozvino kana AC. Paunenge uchishandisa AC welding, iyo evaporation ye zinc inoreruka kupfuura kana yakananga ikozvino yakabatana. Kazhinji, preheating haidiwi pamberi pekututira, uye preheating chete kana ukobvu hweplate hwakakura. Iyo welding yekumhanyisa inofanira kunge ichikurumidza sezvinobvira. Mushure mekuputika, zvikamu zvakasungirirwa zvinofanira kupiswa pa 300 ~ 400 ℃ kuti zviputire kubvisa kushungurudzika kwekudzivirira kudzivirira kutsemuka muzvikamu zvakasungwa panguva yekushandiswa.
4.Brass carbon arc welding Kana mhangura carbon arc welding, wire 221, wire 222, wire 224 uye mamwe mawaya emagetsi anosarudzwa maererano nekuumbwa kwezvinhu zvepasi. Iwe unogona zvakare kushandisa tambo dzekushongedza dzepamba dzendarira kupinza. Iyo gasi mumiriri 301 kana zvimwewo zvinogona kushandiswa seyekuyerera muwelding. Iyo welding inofanira kushandiswa pfupi arc kuderedza zinc evaporation uye kupisa kukuvara.
