MIG waya dzinoita basa rakakosha muwelding yemazuva ano. Kuti tiwane mibairo yemhando yepamusoro-soro, tinoda kuziva nzira yekusarudza nekushandisa waya dzeMIG nemazvo.
Nzira yekusarudza MIG waya?
Chekutanga pane zvese, isu tinofanirwa kuve takavakirwa pane hwaro zvinhu, mhando dzakasiyana dzechigadziko zvinhu zvinotarisa kutungamira kwekusarudzwa kwewaya. Zvakajairwa hwaro zvinhu kabhoni simbi, Stainless simbi, aluminium alloy uye zvichingodaro. Kune kabhoni simbi, kusarudzwa kwewelding wayainofanira kuva yakavakirwa pachiyero chesimba rayo. Yakaderera-yakasimba kabhoni simbi inogona kusarudza yakajairwa kabhoni simbi welding waya, nepo yakakwirira-simba kabhoni simbi inoda yakakwirira simba waya kuti ive nechokwadi chekuita mushure mewelding. Kune mhando dzakawanda dzesimbi isina tsvina, kusanganisira austenitic simbi isina tsvina, ferritic simbi isina tsvina, martensitic simbi isina tsvina nezvimwe zvakadaro. Imwe neimwe giredhi yesimbi isina simbi ine yayo yakasarudzika yemakemikari kuumbwa uye maitiro ekuita, saka iwe unofanirwa kusarudza iyo simbi isina tsvina waya kuti ienderane, kuitira kuti uve nechokwadi chekuti kuramba kwecorrosion uye ma mechanic properties ye weld inopindirana nezvinhu zvevabereki.
Ehe, iyo welding performance zvinodiwa nesu muchikamu chekufungisisa, izvo zvinodikanwa zvesimba zve weld ndeimwe yehwaro hwakakosha hwekusarudzwa kwewaya. Kana iyo weld inoda kumira mitoro yakakwirira, ipapo iyo yakakwirira simba waya inofanira kusarudzwa. Izvi zvinoita kuti mubatanidzwa we welded usatyoke panguva yekushandiswa. Kune welding ine corrosion resistance inodiwa, senge maworkpieces anoshandiswa munzvimbo dzakaoma senge indasitiri yemakemikari negungwa, zvinodikanwa kusarudza waya dzewelding dzinoenderana necorrosion resistance. Kana iyo welded workpiece inoda kuva nekuoma kwakanaka kana kuderera-kupisa kushanda, iwe unodawo kunyatsosarudza waya yakakodzera kuti usangane nezvinodiwa izvi zvakakosha.
Chechipiri, tinofanira kuziva dhayamita waya. Sarudzo yewaya dhayamita uye welding ikozvino, welding chinzvimbo uye base material ukobvu inowirirana zvakanyanya. Kazhinji kutaura, hombe welding ikozvino uye gobvu base material inoda kushandiswa kwewaya yakakora. Izvi zvinodaro nekuti waya dzakakora dzinogona kumirisana nemhepo dzakakwirira uye zvakare inopa yakawanda yekuzadza simbi kuti ive nechokwadi chekusimba kweiyo weld. Mukuenzanisa nekutetepa kweplate welding, mawaya madiki edhayamita anowanzo kusarudzwa kuitira kuderedza kupisa kwekupisa uye kudzivirira kupisa-kuburikidza uye kukanganisa. Munzvimbo dzakasiyana-siyana welding, zvinodikanwawo kusarudza dhayamita yakakodzera yewaya welding. Semuenzaniso, munzvimbo yekumusoro welding, nekuda kwekuoma kwekushanda, kuitira kuti kufambisa basa uye kuve nechokwadi chehutano hwekushongedza, inofanira kusarudza tambo yakaonda.
Pamusoro peizvi, isu tinofanirwa kubatanidza iyo welding process parameters mukusarudza kwewaya, akasiyana MIG welding process parameters, senge welding current, voltage, welding speed, etc., inewo zvakakosha pasarudzo yewaya. Zvinofanira kwakavakirwa chaiyo nomoto muitiro parameters kusarudza waya anogona kuenderana parameters izvi. Muchiitiko chepamusoro chemazuva ano uye chepamusoro-soro, zvakakosha kuve nechokwadi kuti waya inogona kunyunguduka zvakafanana uye inogadzira weld yepamusoro-soro muhutano hwepamusoro-soro. Izvo zvinodiwa kuti usarudze welding wire ine yakanaka deposition properties uye kugadzikana.
Panguva imwecheteyo, isu tinodawo kufunga nezvekugadzikana kwekupa waya uye mushure mekutengesa-basa. Sarudza mhando yewaya ine mukurumbira wakanaka uye yakavimbika nzira dzekupa kuti uve nechokwadi chekuti hapazoshaikwa waya mukuita welding. TANKII Alloy ine mawaya akawanda emagetsi ane hutano hwakagadzikana, kana iwe uchida, tapota taura nesu.
Zvino ndedzipi dziviriro dzekushandisaMIG welding waya?
Chekutanga kutaura ndechekuti maererano nemidziyo, zvakakosha kusarudza welder yakakodzera MIG welding. Kuita kwewelder kunofanira kugadzikana, uye kubuda ikozvino uye voltage inofanira kuva yakarurama. Panguva imwecheteyo, iva nechokwadi chekuti welder yakanyatsodzika pasi kudzivirira electrocution. Kushanda kwakajairwa kwewaya yekudyisa system ndiyo kiyi yekuona welding mhando. Muchina wekudyisa waya unofanirwa kufamba zvakanaka uye kudzvanywa kwevhiri rekudya kunofanira kuva pakati nepakati kudzivirira kusagadzika waya yekudyisa kana kutsvedza waya. Mukuwedzera, chubhu yekudyisa waya inofanira kucheneswa nguva dzose kudzivirira kuvhara.
Kusarudzwa kwegasi rekudzivirira kunokosha zvakare. Magasi ekudzivirira akajairika argon, helium kana musanganiswa wavo. Iva nechokwadi chekuti kuchena kwegasi rekudzivirira kunosangana nezvinodiwa kuti uve nechokwadi chekushongedza. Kugadziriswa kunonzwisisika kwekudzivirira gasi kuyerera kunokosha zvikuru. Kazhinji kutaura, kuyerera kwegasi kunofanirwa kugadziridzwa zvinoenderana neiyo welding ikozvino, waya dhayamita uye welding chinzvimbo uye zvimwe zvinhu. Mukuwedzera iyo welding process, kuve nechokwadi chekudzivirira kwakanaka kwegasi kutenderedza nzvimbo yewelding, kudzivirira kupindira kwemhepo mudziva rakanyungudutswa.
Izvo zvinofanirwa kucherechedzwa kuti isu tinowanzo sarudza yakakodzera MIG waya zvinoenderana nechinhu, ukobvu uye welding zvinodiwa zvehwaro zvinhu. Iyo dhayamita, kuumbwa kwemakemikari uye mechanical zvimiro zvewaya welding inofanira kufanana nehwaro zvinhu. Tinofanira kutarisa kunaka kwewaya yewelding tisati tashandisa, toichenesa kana paine ngura nemafuta. Dzora kureba kwekuwedzera kwewaya welding. Kazhinji kutaura, kureba kwetambo kunenge ka10 dhayamita yetambo yakakodzera. Kutambanudza kureba kwenguva refu kuchaita kuti kuwedzere kupikisa, kuitira kuti waya inopisa, inokanganisa kunaka kwekushongedza.
Mukuwedzera, nzvimbo dzakasiyana-siyana dzekushongedza dzine zvinodiwa zvakasiyana zvekugadzirisa. Mune iyo flat welding, vertical welding, horizontal welding uye back welding position welding, inofanirwa kugadzirisa maparamendi ewelding uye nzira dzekushandisa kuti ive nechokwadi chemhando yewelding. Pakuputira zvimwe zvinhu zvakaita semahwendefa akakora kana simbi yakakwira kabhoni, kupisa kunogona kudikanwa kudzivirira kuputika. Panguva imwecheteyo, iyo interlayer tembiricha inofanira kudzorwa kuti irege kukwirira zvakanyanya kana kuderera. Munguva yewelding process, slag uye spatter pamusoro peiyo weld inofanirwa kucheneswa nekufamba kwenguva kuti ive nechokwadi chekutaridzika kwemhando yeweld uye kufambira mberi kwakatsetseka kwekutevera welding.
