1.Ukuhlelwa
I-arc welding inokwahlulwa ibewelding arc manual, i-semi-automatic (arc) i-welding, i-automatic (arc) i-welding. I-automatic (arc) welding ngokuqhelekileyo ibhekisela kwi-arc ye-arc ye-welding ezenzekelayo-indawo ye-welding igutyungelwe ngumaleko okhuselayo we-flux, ucingo lwe-photonic olwenziwe nge-filler metal lufakwe kwi-flux layer, kwaye i-welding metal ivelisa i-arc, i-arc. wangcwatywa phantsi umaleko flux, kunye nobushushu obuveliswa arc inyibilika ucingo weld, flux kunye nesiseko metal ukwenza weld, kunye nenkqubo welding automated. Eyona isetyenziswa ngokuqhelekileyo yi-arc welding manual.
2.Inkqubo esisiseko
Inkqubo esisiseko ye-arc welding manual yile ilandelayo: a. Coca umphezulu we-welding phambi kwe-welding ukwenzela ukuba ungachaphazeli umgangatho we-arc ignition kunye ne-weld seam. b. Lungisa ifom edibeneyo (uhlobo lwe-groove). Indima ye-groove kukwenza intonga ye-welding, i-welding wire okanye itotshi (i-nozzle etshiza i-acetylene-oxygen flame ngexesha lokutshisa i-gas welding) ngqo ezantsi kwi-groove ukuqinisekisa ukungena kwe-welding, kwaye inceda ukususwa kwe-slag kunye nokuququzelela okufunekayo. oscillation intonga welding kwi groove ukufumana fusion elungileyo. Imilo kunye nobukhulu be-groove ikakhulu kuxhomekeke kwizinto ezidityanisiweyo kunye neenkcukacha zayo (ubukhulu becala), kunye nendlela ye-welding eyamkelweyo, ifom ye-weld seam, njl. iindawo ezibhityileyo ezinobunzima be<3mm; I-Flat groove - ifanelekile kwiindawo ezincinci ze-3 ~ 8mm; I-groove ene-V - ifanelekile kwi-workpieces kunye nobukhulu be-6 ~ 20mm (i-welding enye-sided); Umzobo we-Schematic we-weld groove uhlobo lwe-X-uhlobo lwe-groove - ilungele i-workpieces kunye nobukhulu be-12 ~ 40mm, kwaye kukho i-symmetrical kunye ne-asymmetrical X grooves (i-welding ephindwe kabini); I-groove efana ne-U - ifanelekile kwii-workpieces ezinobunzima be-20 ~ 50mm (i-welding enye-sided); I-groove e-U-shaped groove - ilungele i-workpieces kunye nobukhulu be-30 ~ 80mm (i-welding ephindwe kabini). I-engile ye-groove idla ngokuthathwa ukusuka kuma-60 ukuya kuma-70 °, kunye nenjongo yokusebenzisa imiphetho ebuthuntu (ekwabizwa ngokuba yingcambu yokuphakama) kukuthintela ukuvutha kwe-weldment, ngelixa umsantsa ukuququzelela ukungena kwe-welding.
3.Iiparamitha eziphambili
Iiparameters ezibaluleke kakhulu kwiimpawu ze-welding ze-arc welding zezi: uhlobo lwentonga ye-welding (kuxhomekeke kwizinto eziphathekayo zesiseko), ububanzi be-electrode (kuxhomekeke kubukhulu be-weldment, indawo ye-weld, inani le-welding layers, i-welding speed, i-welding current, njl. .), i-welding current, i-welding layer, njl. Ukongeza kwi-welding ye-arc eqhelekileyo ekhankanywe ngasentla, ukwenzela ukuba kuphuculwe ngakumbi umgangatho we-welding, iphinda isetyenziswe: i-gas shielded arc welding: umzekelo;i-argon arc weldingusebenzisa i-argon njengegesi ekhuselayo kwindawo ye-welding, i-carbon dioxide ekhuselekileyo ye-welding usebenzisa i-carbon dioxide njenge-gas ekhuselayo kwindawo ye-welding, njl., umgaqo osisiseko ku-weld kunye ne-arc njengomthombo wobushushu, kwaye kwangaxeshanye ngokuqhubekayo. ukutshiza igesi ekhuselayo ukusuka kumlomo wesitshizi sompu ukwahlula umoya kwisinyithi esinyibilikisiweyo kwindawo yokuwelda ukukhusela i-arc kunye nesinyithi elulwelo kwichibi lokuwelda ukusuka kwioksijini, initrogen, iHydrogen kunye nolunye ungcoliseko ukufezekisa injongo yokuphucula i-arc. umgangatho we-welding. I-Tungsten argon arc welding: intonga ye-tungsten yensimbi enendawo ephezulu yokunyibilika isetyenziswa njenge-electrode eyenza i-arc xa i-welding, kunye ne-arc welding phantsi kokhuseleko lwe-argon, ehlala isetyenziselwa isinyithi esingenasici, i-alloy yobushushu obuphezulu kunye nokunye ukuwelda. ngeemfuno ezingqongqo. I-Plasma arc welding: Le yindlela yokuwelda ephuhliswe yi-tungsten argon arc welding, kwi-nozzle aperture yomatshini we-Arc welding yesayizi yangoku isigwebo: yangoku encinci: i-welding bead emxinwa, ukungena okunzulu, kulula ukwenza phezulu kakhulu, akuxutywanga, akudityaniswanga. ngokusebenzisa, i-slag, i-porosity, i-weld rod adhesion, arc breaking, no lead arc, njl. i-splash inkulu, i-overburn, i-deformation inkulu, i-tumor ye-weld kunye nokunye.
