1. Gulu
Arc kuwotcherera kungagawidwe kukhalakuwotcherera arc manual, kuwotcherera kwa semi-automatic (arc), kuwotcherera kodziwikiratu (arc). Kuwotcherera kwamadzi (arc) nthawi zambiri kumatanthawuza kuwotcherera kwamadzi kwamadzi - malo owotchererawo amakutidwa ndi chotchinga chotchinga, waya wa Photonic wopangidwa ndi chitsulo chodzaza ndi chitsulo umalowetsedwa mu gawo lotulutsa, ndipo chitsulo chowotcherera chimapanga arc, arc ndi m'manda pansi pa wosanjikiza flux, ndi kutentha kwaiye ndi arc amasungunula weld waya, flux ndi m'munsi zitsulo kupanga weld, ndi kuwotcherera ndondomeko basi. Chomwe chimagwiritsidwa ntchito kwambiri ndi kuwotcherera arc pamanja.
2.Basic ndondomeko
Njira yoyambira kuwotcherera arc ndi motere: a. Tsukani malo owotcherera musanayambe kuwotcherera kuti zisakhudze mtundu wa kuyatsa kwa arc ndi msoko wowotcherera. b. Konzani mawonekedwe olowa (mtundu wa groove). Udindo wa poyambira ndi kupanga kuwotcherera ndodo, kuwotcherera waya kapena nyali (nozzle kuti kupopera acetylene-oksijeni lawi pa mpweya kuwotcherera) molunjika pansi pa poyambira kuonetsetsa kuwotcherera malowedwe, ndipo zimathandiza kuti slag kuchotsa ndi kutsogolera zofunika. oscillation wa kuwotcherera ndodo mu poyambira kupeza bwino maphatikizidwe. Maonekedwe ndi kukula kwa poyambira makamaka zimadalira welded zakuthupi ndi specifications (makamaka makulidwe), komanso kuwotcherera njira anatengera, mawonekedwe a weld msoko, etc. Common grooved mitundu mu ntchito zothandiza ndi: zopindika mfundo - oyenera zoonda ndi makulidwe <3mm; Lathyathyathya poyambira - oyenera mbali woonda 3 ~ 8mm; poyambira V woboola pakati - oyenera workpieces ndi makulidwe a 6 ~ 20mm (kuwotcherera mbali imodzi); Chithunzi chojambula cha weld poyambira mtundu X-mtundu poyambira - oyenera workpieces ndi makulidwe a 12 ~ 40mm, ndipo pali symmetrical ndi asymmetrical X groove (kuwotcherera pawiri-mbali); poyambira U-woboola pakati - oyenera workpieces ndi makulidwe a 20 ~ 50mm (kuwotcherera mbali imodzi); Poyambira woboola pakati pa U - yoyenera zida zogwirira ntchito ndi makulidwe a 30 ~ 80mm (kuwotcherera mbali ziwiri). Mphepete mwa groove nthawi zambiri imatengedwa kuchokera ku 60 mpaka 70 °, ndipo cholinga chogwiritsa ntchito m'mphepete mwake (chomwe chimatchedwanso kutalika kwa mizu) ndikuletsa kuwotcherera kuti zisawotchere, pomwe kusiyana kwake ndikupangitsa kuti kuwotcherera kulowe.
3.Magawo akuluakulu
Zofunika kwambiri mu kuwotcherera specifications arc kuwotcherera ndi: kuwotcherera ndodo mtundu (malingana ndi zakuthupi m'munsi), elekitirodi awiri (malingana weldment makulidwe, weld udindo, chiwerengero cha zigawo kuwotcherera, liwiro kuwotcherera, kuwotcherera panopa, etc. .), kuwotcherera panopa, kuwotcherera wosanjikiza, etc. Kuwonjezera tatchulazi wamba arc kuwotcherera, pofuna kupititsa patsogolo khalidwe kuwotcherera, amagwiritsidwanso ntchito: mpweya kutetezedwa arc kuwotcherera: mwachitsanzo;kuwotcherera argon arcntchito argon monga kutchinga mpweya m'dera kuwotcherera, mpweya wotetezedwa kuwotcherera ntchito mpweya woipa monga kutchinga mpweya m'dera kuwotcherera, etc., mfundo yaikulu ndi kuwotcherera ndi arc monga gwero kutentha, ndipo nthawi yomweyo mosalekeza. kupopera mpweya woteteza ku nozzle wa mfuti kutsitsi kudzipatula mpweya ku chitsulo chosungunuka m'dera kuwotcherera kuteteza arc ndi madzi zitsulo mu dziwe kuwotcherera mpweya, nayitrogeni, haidrojeni ndi kuipitsa zina kukwaniritsa cholinga kuwongolera khalidwe la kuwotcherera. Kuwotcherera kwa tungsten argon: ndodo yachitsulo yokhala ndi malo osungunuka kwambiri imagwiritsidwa ntchito ngati electrode yomwe imapanga arc pamene kuwotcherera, ndi kuwotcherera kwa arc pansi pa chitetezo cha argon, chomwe nthawi zambiri chimagwiritsidwa ntchito muzitsulo zosapanga dzimbiri, aloyi yotentha kwambiri ndi kuwotcherera kwina. ndi zofunika kwambiri. Kuwotcherera kwa Plasma arc: Iyi ndi njira yowotcherera yomwe imapangidwa ndi kuwotcherera kwa tungsten argon arc, pobowola makina a Arc kuwotcherera pakali pano kukula kwake: yapang'onopang'ono: yopapatiza mkanda, kulowa mozama, yosavuta kupanga yokwera kwambiri, yosakanizidwa, osati yowotcherera. kupyola, slag, porosity, weld ndodo adhesion, arc kuthyoka, palibe lead arc, etc. Pakali pano ndi yaikulu: weld mkanda ndi waukulu, kuya kwa malowedwe ndi lalikulu, kuluma m'mphepete, kuwotcha-kupyola, dzenje chepetsa, kuwaza ndi lalikulu, kuwotcha, mapindikidwe ndi lalikulu, chotupa weld ndi zina zotero.
