1.Kuronga
Arc welding inogona kukamurwa kuitamanual arc welding, semi-automatic (arc) welding, automatic (arc) welding. Otomatiki (arc) welding kazhinji inoreva kunyudzwa kwearc otomatiki welding - iyo saiti yekubatira yakafukidzwa neyakavhariridza yekuyerera, iyo photonic wire yakagadzirwa nesimbi yekuzadza inopinzwa mukati meiyo flux layer, uye simbi yekubatira inogadzira arc, iyo arc inovigwa pasi peiyo flux layer, uye kupisa kunogadzirwa nearc kunonyungudutsa weld welding, weld simbi uye simbi inonyunguduka inogadzira iyo weld simbi, iyo inoyerera simbi. Inonyanya kushandiswa ndeye manual arc welding.
2.Basic process
Iyo yakakosha maitiro emanual arc welding ndeaya anotevera: a. Chenesa iyo welding pamusoro usati welding kuitira kuti isakanganise kunaka kwearc ignition uye weld seam. b. Gadzirira fomu yakabatana (groove type). Basa re groove ndere kugadzira tsvimbo yewelding, welding wire kana torch (nozzle inopfapfaidza acetylene-oxygen murazvo panguva yekupisa gasi) yakananga muzasi megirovha kuti ive nechokwadi chekupinda mukati, uye inobatsira kubviswa kwe slag uye kufambisa kudikanwa kweiyo welding tsvimbo kuti iwane mugororo wakanaka. Chimiro uye saizi yegororo inonyanya kutsamira pane yakakwenenzverwa zvinhu uye mataurirwo ayo (kunyanya ukobvu), pamwe chete nenzira yewelding yakagamuchirwa, chimiro che weld seam, etc. Common grooved types in practical applications are: curved joints - akakodzera mativi matete ane gobvu <3mm; Flat groove - yakakodzera kune dzakaonda zvikamu zve 3 ~ 8mm; V-shaped groove - inokodzera workpieces nehupamhi hwe 6 ~ 20mm (single-sided welding); Schematic diagram ye weld groove type X-type groove - inokodzera maworkpieces ane ukobvu hwe12 ~ 40mm, uye kune symmetrical uye asymmetrical X grooves (double-sided welding); U-shaped groove - inokodzera workpieces nehupamhi hwe20 ~ 50mm (single-sided welding); Kaviri U-shaped groove - inokodzera maworkpiece ane ukobvu hwe30 ~ 80mm (kaviri-sided welding). Iyo groove angle inowanzotorwa kubva pa60 kusvika 70 °, uye chinangwa chekushandisa micheto yakagomara (inonziwo midzi kureba) ndeyekudzivirira weldment kubva pakupisa nepakati, nepo gap iri kufambisa welding kupinda.
3.Main parameters
Iyo inonyanya kukosha parameters mune welding yakatarwa yearc welding ndeye: welding tsvimbo yemhando (zvichienderana neyakagadzikwa zvinhu), electrode dhayamita (zvinoenderana neweldment ukobvu, weld chinzvimbo, nhamba yewelding layer, welding speed, welding current, etc.), welding current, welding layer, etc. shielded arc welding: semuenzaniso,argon arc weldingkushandisa argon sechidziviriro gasi munzvimbo yewelding, carbon dioxide yakadzivirirwa welding uchishandisa kabhoni dhiabhorosi sechidziviriro gasi munzvimbo yewelding, nezvimwewo, musimboti wekuti weld nearc senzvimbo yekupisa, uye panguva imwe chete uchiramba uchimwaya gasi rinodzivirira kubva pamuromo wepfuti yekupfapfaidza kuti iparadzanise mhepo kubva kune yakanyungudutswa nzvimbo yesimbi kubva kune yakanyungudutswa simbi mumudziva wesimbi. okisijeni, nitrogen, Hydrogen uye kumwe kusvibiswa kuzadzisa chinangwa chekuvandudza kunaka kwewelding. Tungsten argon arc welding: simbi tungsten tsvimbo ine yakakwirira kunyunguduka poindi inoshandiswa se electrode inogadzira arc kana ichiturika, uye arc welding pasi pedziviriro yeargon, iyo inowanzoshandiswa musimbi isina tsvina, yakakwirira-tembiricha alloy uye kumwe kukwenenzverwa nezvinodiwa zvakasimba. Plasma arc welding: Iyi inzira yewelding yakagadzirwa ne tungsten argon arc welding, mumuromo wemuromo wemuchina Arc welding ikozvino saizi kutonga: diki ikozvino: yakamanikana welding bead, kudzika kupinza, nyore kuumba yakakwira zvakanyanya, isina kusanganiswa, isina kusungirirwa kuburikidza, slag, porosity, weld tsvimbo adhesion, weld adhesion, etc. yakafara, kudzika kwekupinda kwakakura, mupendero wekurumwa, kupisa-kuburikidza, gomba rekudzikira, kupuruzira kwakakura, kupisa kwakanyanya, deformation yakakura, bundu re weld uye zvichingodaro.
