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 - nzvimbo yekubatira yakafukidzwa neinodzivirira layer ye flux, iyo photonic wire yakagadzirwa nesimbi yekuzadza inopinzwa mu flux layer, uye simbi yekubatira inogadzira arc, iyo arc iri. akavigwa pasi pemvura inoyerera, uye kupisa kunogadzirwa nearc kunonyungudutsa weld wire, flux uye base simbi kuumba weld, uye welding muitiro otomatiki.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 regoroko nderekugadzira tsvimbo yewelding, welding wire kana torch (nozzle inopfapfaidza acetylene-oxygen murazvo panguva yekupisa gasi) yakananga pasi pegorovha kuti ive nechokwadi chekupinda mukati, uye inobatsira kubviswa kwe slag uye kufambisa zvinodiwa. oscillation ye welding tsvimbo mu groove kuti uwane yakanaka fusion.Chimiro uye saizi yegirovha inonyanya kuenderana neyakagadzirwa zvinhu uye mataurirwo ayo (kunyanya ukobvu), pamwe nenzira yewelding yakagamuchirwa, chimiro che weld seam, etc. Common grooved types in practical applications are: curved joints - akakodzera zvikamu zvitete zvine ukobvu hwe <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 riri rekufambisa kupinda kwewelding.
3.Main parameters
Iyo inonyanya kukosha maparamendi mune welding yakatarwa yearc welding ndeye: welding tsvimbo yerudzi (zvichienderana neyakagadzirwa zvinhu), electrode dhayamita (zvinoenderana nekukora kweweldment, weld chinzvimbo, nhamba yewelding layer, welding speed, welding current, etc. .), welding current, welding layer, etc. Kuwedzera kune yakataurwa pamusoro apa yakajairika arc welding, kuitira kuti uwedzere kunatsiridza kunaka kwewelding, inoshandiswawo: gas shielded arc welding: semuenzaniso, argon arc welding uchishandisa argon. sechidziviriro gasi munzvimbo yewelding, carbon dioxide yakadzivirirwa welding uchishandisa kabhoni dioksijeni seyekudzivirira gasi munzvimbo yewelding, nezvimwewo, musimboti wekutanga ndeye weld nearc senzvimbo yekupisa, uye panguva imwe chete uchiramba uchipfapfaidza kudzivirira. gasi kubva mumuromo wepfuti yekupuruzira kuti iparadzanise mhepo kubva kusimbi yakanyungudutswa munzvimbo yewelding kuchengetedza arc uye simbi yemvura mudziva rekukweshesa kubva kuokisijeni, nitrogen, Hydrogen uye kumwe kusvibiswa kuzadzisa chinangwa.yekuvandudza kunaka kwewelding.Tungsten argon arc welding: simbi tungsten tsvimbo ine yakakwirira kunyunguduka poindi inoshandiswa se electrode inoburitsa arc kana ichiturika, uye arc welding pasi pekuchengetedzwa kweargon, iyo inowanzoshandiswa musimbi isina tsvina, yakakwirira-tembiricha alloy uye kumwe kukwenenzvera. nezvinodiwa zvakasimba.Plasma arc welding: Iyi inzira yewelding yakagadziridzwa netungsten argon arc welding, mumuromo wemuromo wemuchina Arc welding yazvino saizi kutonga: diki ikozvino: nhete welding bead, kudzika kupinza, nyore kuumba yakakwira zvakanyanya, isina kubatanidzwa, isina simbi. kuburikidza ne, slag, porosity, weld rod adhesion, arc breaking, no lead arc, etc. Ikozvino yakakura: weld bead yakakura, kudzika kwekupinda kwakakura, kuruma kumucheto, kupisa-kuburikidza, gomba rekudzikira, iyo splash yakakura, iyo overburn, deformation yakakura, weld bundu uye zvichingodaro.
