1. Gulu
Arc kuwotcherera kungagawidwe kukhalakuwotcherera arc manual, kuwotcherera kwa semi-automatic (arc), kuwotcherera kodziwikiratu (arc).Kuwotcherera kwa automatic (arc) nthawi zambiri kumatanthauza kuwotcherera kwamadzi kwamadzi - malo owotcherera amakutidwa ndi chingwe choteteza cha flux, waya wa photonic wopangidwa ndi chitsulo chodzaza ndi chitsulo umalowetsedwa mu gawo la flux, ndipo chitsulo chowotcherera chimapanga arc, arc ndi m'manda pansi 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 yayikulu yowotcherera 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 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 zinthu welded 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;Mphepete mwathyathyathya - yoyenera mbali zowonda za 3 ~ 8mm;poyambira V - oyenera workpieces ndi makulidwe a 6 ~ 20mm (kuwotcherera mbali imodzi);schematic chithunzi 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 ndikuthandizira kuwotcherera.
3.Main parameters
Zofunika kwambiri mu kuwotcherera specifications arc kuwotcherera ndi: kuwotcherera ndodo mtundu (malingana ndi zinthu za m'munsi), elekitirodi awiri (malingana ndi makulidwe weldment, weld udindo, chiwerengero cha zigawo kuwotcherera, liwiro kuwotcherera, kuwotcherera panopa, etc. .), kuwotcherera panopa, kuwotcherera wosanjikiza, etc. Kuwonjezera tatchulazi wamba kuwotcherera arc, kuti apititse patsogolo khalidwe kuwotcherera, amagwiritsidwanso ntchito: mpweya kutetezedwa arc kuwotcherera: Mwachitsanzo, Argon Arc kuwotcherera ntchito Argon. monga chotchinjiriza mpweya m'dera kuwotcherera, mpweya wotetezedwa kuwotcherera ntchito mpweya woipa monga chotchinga mpweya m'dera kuwotcherera, etc., mfundo yaikulu ndi kuwotcherera ndi arc monga gwero kutentha, ndipo nthawi yomweyo mosalekeza utsi zoteteza. mpweya 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.za kuwongolera khalidwe la kuwotcherera.Tungsten argon arc kuwotcherera: 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 wotentha kwambiri ndi kuwotcherera kwina. ndi zofunika kwambiri.Kuwotcherera kwa Plasma arc: Iyi ndi njira yowotcherera yomwe imapangidwa ndi kuwotcherera kwa tungsten argon arc, mu kabowo kakang'ono ka makina a Arc kuwotcherera pakali pano kukula kwachigamulo: chapano chaching'ono: mkanda wopapatiza, kulowera kosaya, kosavuta kupanga kokwera kwambiri, kosaphatikizika, kosamangika. kupyola, slag, porosity, weld ndodo adhesion, arc kusweka, palibe lead arc, etc. Pakali pano ndi lalikulu: weld bead ndi lalikulu, kuya kwa kulowa ndi kwakukulu, kuluma m'mphepete, kuwotcha-kupyola, dzenje locheperako, kuwaza ndi lalikulu, kuwotcha, mapindikidwe ndi lalikulu, chotupa weld ndi zina zotero.
