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 ngumgangatho okhuselayo we-flux, ucingo lwe-photonic olwenziwe nge-filler metal lufakwe kwi-flux layer, kunye nentsimbi ye-welding ivelisa i-arc, i-arc ingcwatywa phantsi kwe-flux layer, kunye nobushushu obuveliswa yi-arc bunyibilika i-welding ye-welding, inkqubo ye-weld ye-weld kunye ne-automa 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-oksijini yomlilo ngexesha le-gas welding) ngokuthe ngqo ezantsi kwe-groove ukuqinisekisa ukungena kwe-welding, kwaye ilungele ukususwa kwe-slag kunye nokuququzelela ukuchithwa okufunekayo kwe-welding rod ukufumana i-groove enhle. Imilo kunye nobukhulu be-groove ikakhulu kuxhomekeke kwizinto ezidibeneyo kunye neenkcukacha zayo (ubukhulu becala), kunye nendlela ye-welding eyamkelweyo, ifom ye-weld seam, njl. 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 ene-U-shaped groove - ifanelekile kwi-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
Eyona parameters ibaluleke kakhulu kwiinkcukacha zokuwelda kwe-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, isantya se-welding, i-welding yangoku, njl.), i-welding yangoku, i-welding layer, njl. ukuwelda kwearc ekhuselweyo: umzekelo,i-argon arc weldingusebenzisa i-argon njengegesi ekhuselayo kwindawo yokuwelda, i-carbon dioxide ekhuselwe ukuwelda usebenzisa i-carbon dioxide njengegesi ekhuselayo kwindawo ye-welding, njl., umgaqo osisiseko ku-weld kunye ne-arc njengomthombo wobushushu, kwaye kwangaxeshanye ngokuqhubekayo ukutshiza igesi ekhuselayo ukusuka kwi-nozzle ye-spray gun ukuba ihlukanise umoya ukusuka kwindawo yokufaka i-welding kunye nokukhusela indawo ye-welding kwi-welding yesinyithi kwi-metal pool. ioksijini, initrogen, iHydrogen kunye nolunye ungcoliseko ukufezekisa injongo yokuphucula umgangatho wokuwelda. 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 ephezulu yobushushu kunye nezinye i-welding eneemfuno ezingqongqo. I-Plasma arc welding: Le yindlela ye-welding eyaphuhliswa yi-tungsten argon arc welding, kwi-nozzle aperture yomatshini we-arc welding ye-arc ubungakanani besigqibo: yangoku encinci: i-welding bead encinci, ukungena okuncinci, kulula ukwenza i-welding ephezulu kakhulu, ingaxutywanga, i-welded ngokusebenzisa, i-slag, i-porosity, i-weld rod adhesion, i-lead bead yangoku, njl njl. ububanzi, ubunzulu bokungena bukhulu, umgca wokuluma, ukutshisa, umngxuma wokucutha, i-splash inkulu, i-overburn, i-deformation inkulu, i-tumor ye-weld njalo njalo.
