Waya dzeMIG dzinoita basa rakakosha mukunamira kwemagetsi kwemazuva ano. Kuti tiwane mhedzisiro yemhando yepamusoro yekunamira, tinofanira kuziva mashandisirwo ewaya dzeMIG nemazvo.
Ungasarudza sei waya yeMIG?
Chekutanga, tinofanira kutevedzera zvinhu zvekutanga, mhando dzakasiyana dzezvinhu zvekutanga dzinosarudza nzira yekusarudzwa kwewaya. Zvinhu zvakajairika zvekutanga isimbi yekabhoni, simbi isingasvibi, aruminiyamu alloy nezvimwewo. Kune simbi yekabhoni, kusarudzwa kwewaya yekunamirainofanira kunge yakavakirwa pasimba rayo. Simbi yekabhoni ine simba shoma inogona kusarudza waya yekuwelda yesimbi yekabhoni, nepo simbi yekabhoni ine simba guru ichida waya yakasimba kuti ive nechokwadi chekuti inoshanda mushure mekuwelda. Kune mhando dzakawanda dzesimbi isingatsvedzeri, kusanganisira austenitic stainless steel, ferritic stainless steel, martensitic stainless steel nezvimwewo. Giredhi rega rega resimbi isingatsvedzeri rine makemikari aro akasiyana uye hunhu hwekushanda, saka unofanirwa kusarudza waya yesimbi isingatsvedzeri inoenderana, kuitira kuti uve nechokwadi chekuti kuramba ngura uye hunhu hwemakanika hweweld zvinoenderana nezvinhu zvemubereki.
Ehe, zvinodiwa pakushanda kwewelding nesu mukufunga kwedu, zvinodiwa zvesimba reweld ndeimwe yehwaro hwakakosha pakusarudza waya. Kana weld ichida kumira mitoro yakakwira, saka waya yakasimba inofanira kusarudzwa. Izvi zvinoita kuti weld joint isatyoke panguva yekushandiswa. Pawelding ine zvinodiwa zvekudzivirira ngura, senge maworkpiece anoshandiswa munzvimbo dzakaoma dzakadai seindasitiri yemakemikari negungwa, zvakakosha kusarudza waya dzewelding dzine kudzivirira ngura zvinoenderana. Kana weld workpiece ichida kusimba kwakanaka kana kushanda kwakaderera, unofanirwawo kusarudza waya yakakodzera kuti isangane nezvinodiwa izvi zvakakosha.
Chechipiri, tinofanira kuziva dhayamita yewaya. Sarudzo yedhayamita yewaya nemagetsi ekuwelda, nzvimbo yekuwelda uye ukobvu hwezvinhu zvepasi zvakabatana zvakanyanya. Kazhinji, magetsi ekuwelda akakura uye zvinhu zvepasi zvakakora zvinoda kushandiswa kwewaya yakakora. Izvi zvinodaro nekuti waya dzakakora dzinogona kumira mafungu akakwira uye zvakare dzinopa simbi yakawanda yekuzadza kuti ive nechokwadi chekusimba kweweld. Kana tichienzanisa newelding yeplate tete, waya diki dzedhayamita dzinowanzo sarudzwa kuitira kuderedza kupisa kwewelding uye kudzivirira kupisa nekukanganisika. Munzvimbo dzakasiyana dzekuwelda, zvakakoshawo kusarudza dhayamita yakakodzera yewaya yekuwelda. Semuenzaniso, munzvimbo yekuwelda yepamusoro, nekuda kwekuoma kwekushanda, kuitira kuti basa rifambe zvakanaka uye kuve nechokwadi chekuti welding yakanaka, unofanirwa kusarudza waya yakatetepa.
Pamusoro peizvi, tinofanira kusanganisa maparamita ekugadzirisa welding pakusarudza waya, maparamita akasiyana eMIG ekugadzirisa welding, akadai sewelding current, voltage, welding speed, nezvimwewo, anewo simba guru pakusarudza waya. Inofanira kunge yakavakirwa paparamita chaiyo yekugadzirisa welding kuti waya ikwanise kuenderana neparamita idzi. Panyaya yewelding high current uye high speed, zvakakosha kuve nechokwadi chekuti waya inogona kunyunguduka zvakaenzana uye kugadzira weld yepamusoro muwelding high speed. Zvakakosha kusarudza waya yekuchenesa ine hunhu hwakanaka hwekuisa uye kugadzikana.
Panguva imwe chete, tinofanirawo kufunga nezvekugadzikana kwewaya uye sevhisi yekubuda kwewaya mushure mekutengesa. Sarudza rudzi rwewaya rine mukurumbira wakanaka uye nzira dzakavimbika dzekupa kuti uve nechokwadi chekuti hapana kushomeka kwewaya mukuita kwewelding. TANKII Alloy ine waya dzakasiyana-siyana dzewelding dzine mhando yakagadzikana, kana uchida, ndapota taura nesu.
Saka ndedzipi nzira dzekudzivirira pakushandisaWaya yekunamira yeMIG?
Chinhu chekutanga kutaura ndechekuti kana tichitaura nezvemichina, zvakakosha kusarudza welder yakakodzera MIG welding. Kushanda kwewelder kunofanira kunge kwakagadzikana, uye simba remagetsi rinobuda uye voltage zvinofanira kunge zvakarurama. Panguva imwe chete, iva nechokwadi chekuti welder iri pasi zvakanaka kudzivirira electrocution. Kushanda kwakajairika kwewaya yekudyisa ndiyo kiyi yekuona kuti welding yakanaka. Waya yekudyisa inofanira kufamba zvakanaka uye kumanikidzwa kwevhiri rekudyisa waya kunofanira kunge kuri pakati nepakati kudzivirira waya yekudyisa isina kugadzikana kana kutsvedza kwewaya. Pamusoro pezvo, chubhu yekudyisa waya inofanira kucheneswa nguva nenguva kudzivirira kuvharika.
Sarudzo yegasi rinodzivirira inokoshawo. Magasi anodzivirira anowanzo shandiswa iargon, helium kana musanganiswa wawo. Iva nechokwadi chekuti kuchena kwegasi rinodzivirira kunosangana nezvinodiwa kuti uve nechokwadi chekuti welding yakanaka. Kugadziriswa kwakanaka kwegasi rinodzivirira kwakakosha zvikuru. Kazhinji, kuyerera kwegasi kunofanirwa kugadziriswa zvichienderana ne welding current, dhayamita yewaya nenzvimbo ye welding nezvimwe zvinhu. Pamusoro pezvo, maitiro e welding, kuve nechokwadi chekudzivirira kwakanaka kwegasi munzvimbo ye welding, kudzivirira kupinda kwemhepo mudziva rakanyungudutswa.
Zvinofanira kucherechedzwa kuti tinowanzo sarudza waya yeMIG yakakodzera zvichienderana nezvinhu, ukobvu uye zvinodiwa pakushongedza chigadziko. Dhayamita, makemikari uye hunhu hwemuchina hwewaya yekushongedza tambo zvinofanirwa kuenderana nechigadziko. Tinofanira kutarisa mhando yepamusoro yewaya yekushongedza tambo tisati tashandisa, uye kuichenesa kana paine ngura nemafuta. Dzora kureba kwewaya yekushongedza tambo. Kazhinji, kureba kwewaya kwakapetwa kagumi kupfuura dhayamita yewaya yakakodzera. Kutambanudza kureba kwenguva yakareba kuchaita kuti waya irambe yakasimba, zvekuti kupisa kwewaya kuchikanganisa kunaka kwekushongedza tambo.
Pamusoro pezvo, nzvimbo dzakasiyana dzewelding dzine zvinodiwa zvakasiyana pakuita welding. Muwelding yakatsetseka, welding yakatwasuka, welding yakatambanuka uye welding yekumashure, inofanira kugadzirisa maparamita ewelding uye nzira dzekushandisa kuti ive nechokwadi chekuti welding yakanaka. Pawelding yezvimwe zvinhu zvakaita semaplate akakora kana simbi ine kabhoni yakawanda, kupisa kwekutanga kunogona kudiwa kudzivirira kutsemuka. Panguva imwe chete, tembiricha yeinterlayer inofanira kudzorwa kudzivirira kukwira zvakanyanya kana kuderera zvakanyanya. Munguva yewelding, slag uye spatter pamusoro peweld zvinofanirwa kucheneswa nenguva kuti ive nechokwadi chekuti weld inotaridzika zvakanaka uye kufambira mberi kwakanaka kwewelding inotevera.
