Kana zvasvika pakubatanidza brass, kunyatsogadzirisa zvinhu hakusi kungonaka chete—chinhu chinoita kuti chigadzirwa chigare kwenguva refu, chishande zvakanaka, uye chitaridzike zvakanaka. Ungave uchigadzira zvinhu zveHVAC, zvinobatanidza zvemagetsi, kana zvinhu zvebrass zvekushongedza, nzira isiriyo yekushongedza inogona kukonzera misono ine maburi, kurasikirwa ne zinc, kana kupedzisa kusina kunaka izvo zvinokanganisa mapurojekiti ako. Kana wakambosangana nematambudziko nemhedzisiro isingaenderane nemaitiro eBrass Welding echinyakare, inguva yekutarisa kupfuura zvekutanga: TIG welding ingave mhinduro yawanga uchitsvaga.
Kutanga, ngatitsanangurei zvakakosha zveBrass Welding kuti tigadzirise mamiriro acho. Brass, iyo imhando yemhangura ne zinc, inokosheswa mumaindasitiri nekuda kwekupisa kwayo kwakanaka, kuramba ngura, uye kuchinjika—asi hunhu ihwohwo hunoita kuti zvive zvakaoma kusanganisa. Kusiyana nesimbi, brass ine zinc shoma inofashaira (907°C) yakaderera pane copper's melting point (1083°C), zvichireva kuti kupisa zvakanyanya panguva yekusanganisa kunogona kukonzera zinc kupwanyika. Izvi hazvingonetesi ma weld chete asiwo zvinoburitsa utsi hune chepfu, zvichiwedzera njodzi dzekuchengetedza. Pamusoro pezvo, kupisa kwakanyanya kwebrass kunoreva kuti kupisa kunopera nekukurumidza, zvichiita kuti zviome kuchengetedza dziva re weld rakasimba nenzira dzisina kunyatsojeka.
Iyokusona yendariraIndasitiri inoda mhinduro dzinoenzanisa kushanda zvakanaka nemhando, kunyanya muzvikamu zvakaita semotokari, zvendege, uye zvemapaipi uko zvinhu zvinofanirwa kusangana nezvinodiwa zvakachengeteka uye mashandiro. Pakugadzirwa kwehuwandu hwakawanda, kugara kwakasimba kwakakosha—kusiyana kwesimba reweld kana chitarisiko kunogona kutungamira pakugadzirisa zvinhu zvinodhura kana kudzoserwa kwechigadzirwa. Pabasa rakagadzirwa kana rekushongedza, kupedzisa runako kunova pakati penzvimbo; weld isina kunaka inogona kukanganisa kutaridzika kwemidziyo yemhangura, zviridzwa zvemimhanzi, kana ruzivo rwekuvaka. Izvi zvinoda kutsanangura kuti nei nyanzvi dzakawanda dziri kushandisa TIG welding kuti dzibatanidze brass nemazvo.
Saka, sei TIG welding (inozivikanwawo seGas Tungsten Arc Welding, GTAW) yakakodzera Brass Welding? Ngatitangei neunyanzvi hwayo husina kuenzana. TIG inoshandisa electrode ye tungsten isingadyiwi uye pedal yetsoka yekudzora amperage, zvichibvumira vanowelders kugadzirisa kupisa nekunyatsorongeka. Iyi nhanho yekudzora yakakosha kune brass: inodzivirira kupisa zvakanyanya, inoderedza vaporization ye zinc, uye inoderedza njodzi yekuora - zvikanganiso zvinowanzoonekwa mune dzimwe nzira dzekuwelders senge MIG kana gas welding. Kune machira matete ebrass kana machubhu madiki (anowanzoonekwa mumagetsi uye maHVAC applications), kugona kweTIG kwekuisa kupisa kushoma kunodzivirirawo kukotama, kuchengetedza chimiro chepakutanga uye kusimba kwechinhu chacho.
Chimwe chinhu chikuru chinobatsira pakubatanidza TIG ne brass ndechekuti brass jointing yayo yakachena, isina slag. Kusiyana ne stick welding, TIG haidi flux, izvo zvinobvisa kudiwa kwekuchenesa mushure mekusanganisa slag kubvisa slag residues - inochengetedza nguva yakawanda kumaworkshops ane mabasa akawanda. Gasi rekudzivirira risina simba (rinowanzova argon kana argon-helium mix) rinoshandiswa mukubatanidza TIG rinodzivirirawo dziva re weld kubva mukusvibiswa kwemhepo, kudzivirira oxidation uye kuona kuti musono wakatsetseka, wakafanana wakasimba uye unoyevedza. Izvi zvinoshandura mutambo webasa rebrass rekushongedza kana zvikamu uko kuramba ngura kusingakurukurwi, senge zvikamu zvegungwa kana zvepombi.
Kuchengetedzeka ndeimwe nzvimbo iyo TIG inopenya paBrass Welding. Kunyange zvazvo nzira dzese dzebrass welding dziine njodzi yekusangana nefume yezinc, kudzora kupisa kwakanyatsojeka kweTIG kunoderedza huwandu hwezinc vaporization zvichienzaniswa nenzira dzinopisa zvakanyanya senge oxyacetylene welding. Kana zvakabatana nemhepo inofefetera zvakanaka uye michina yekudzivirira (PPE), TIG inogadzira nzvimbo yekushanda yakachengeteka—chinhu chakakosha kune mabhizinesi ari kutsvaga kutevedzera mitemo yeOSHA neHSE. Pamusoro pezvo, TIG welding haiburitse sparks kana spatter, zvichideredza njodzi dzemoto mumaworkshops ane zvinhu zvinobvira moto.
Zvakakosha kuziva kuti TIG welding haisi mhinduro yehukuru humwe chete, asi kushandiswa kwayo kwakasiyana-siyana kunoita kuti ikwanise kushandiswa zvichienderana nezvinodiwa zvekubatanidza brass nemazvo. Inoshanda ne low-zinc (alpha) uye high-zinc (alpha-beta) brass alloys, uye inogona kubata ukobvu kubva pamageji matete (pasi pe1.5mm) kusvika ku9mm nezvinhu zvakakodzera zvekuzadza. Kune high-zinc brasses, kushandisa zinc-free filler rod uye helium-rich shielding gas kunoderedza kugadzirwa kwefume uye porosity, zvichiita kuti welds dzive dzakasimba uye dzakavimbika.
Kune vatengi nevagadziri vanoongorora sarudzo dzeBrass Welding, sarudzo yacho inoenderana nezvamunonyanya kukoshesa. Kana muchida kumhanya kupfuura zvese, MIG welding ingangove yakakodzera zvikamu zvebrass zvakakora. Asi kana kunyatsoita, kuenderana, uye mhando zvisingadiwi—kunyanya pakushandiswa kwakakosha kana kwekunaka—TIG welding ndiyo sarudzo yakajeka. Inogadzirisa matambudziko akasiyana ebrass sechinhu, inosangana nezvinodiwa zvemaindasitiri akakosha, uye inopa mhedzisiro inoderedza kugadziriswa patsva uye inovandudza kukosha kwechigadzirwa chekupedzisira.
Munyika yekubatanidza brass nemazvo, kugadzirisa makona nenzira dzekubatanidza dzinowanzo kukonzera matambudziko akawanda. Kubatanidza TIG hakusi kungobva patsika dzechinyakare chete—kudyara mumhando yepamusoro kunobhadhara mukushanda kuri nani, mashandiro akachengeteka, uye vatengi vanofara. Ungave uri mugadziri ane ruzivo kana kuti uchangotanga kushanda nebrass, kuchinja kuenda kuTIG kunogona kuva mutsauko pakati pemhedzisiro yakanaka neyakanaka.
