Kukonza Roll Submerged Arc Welding

Kukonza zowotcherera arc pansi pamadzi ndi njira yowotcherera yamphamvu yokwiriridwa, mwachilengedwe pakuwotcherera sikungathe kuwona arc, ndipo zowotcherera zodziwikiratu, zinthu zantchito zimakula kwambiri.Kuwotcherera kwa arc pansi pamadzi, mfundo ya kusankha kuwotcherera mfundo ndi: kuonetsetsa khola woyaka arc, kuwotcherera mawonekedwe ndi kukula kukwaniritsa zofunika, pamwamba aumbike yosalala ndi mwaukhondo, palibe pores mkati, slag, ming'alu, osati kuwotcherera kupyolera, chotupa chowotcherera ndi zina. zolakwika.Njira zosankhidwa zomwe zimagwiritsidwa ntchito nthawi zambiri ndi njira ya tebulo, njira yoyesera, njira yoyeserera, njira yowerengera.Kaya njira ntchito kudziwa magawo, ayenera kudzudzulidwa mu ntchito kuwotcherera, kukwaniritsa kwambiri pamene mosalekeza kuwotcherera.

Malinga ndi ntchito panopa osiyanasiyana monofilamentKuwotcherera kwa arc pansi pamadzi, pamene makulidwe mbale ndi zosakwana 14mm, simungathe kutsegula bevel, msonkhano ndi kusiyana kwina;makulidwe mbale 14 ~ 22mm, zambiri lotseguka V woboola pakati bevel;makulidwe mbale 22 ~ 50mm, lotseguka X woboola pakati bevel;kwa boiler gasi ladle ndi zotengera zina zopanikizika nthawi zambiri amagwiritsa ntchito bevel woboola pakati kapena awiri woboola pakati pa U, kuwonetsetsa kuti pansi wosanjikiza wa weld kudutsa ndikuchotsa slag.Njira zopangira bevel nthawi zambiri zimagwiritsa ntchito makina opangira m'mphepete ndi makina odulira gasi, payenera kukhala kulondola kwapang'onopang'ono.Pazitsulo zowongoka zowongoka ziyenera kuwonjezeredwa kumapeto kwa mbale ya arc-priming ndi mbale yozimitsa arc, kuti muchepetse kuwonongeka kwa arc-priming ndi lead-out.

Pakuti malo kuwotcherera pambuyo mbali welded, zambiri kuonjezera ntchito kutentha kapena sandblasting ndi njira zina kuonetsetsa khalidwe kuwotcherera.

In kuwotcherera arc pansi pamadzi, nthawi zambiri ndikofunikira kusintha kuwotcherera komwe kumayenderana ndi ma arc voltage.Zomwe zikukhudza kuwotcherera pakali pano ndi: makulidwe a mbale, liwiro la kuwotcherera, m'mimba mwake wa waya, ndi zina.

Ukadaulo wowotcherera wa matako owotcherera msoko

Njira zowotcherera pamatako owotcherera msoko ndi: kuwotcherera mbali imodzi ndi kuwotcherera mbali ziwiri;kuwotcherera limodzi wosanjikiza ndi kuwotcherera kwamitundu yambiri;njira ya liner pad ndi njira yopanda liner.Flux PAD njira kumizidwa arc basi kuwotcherera, amene kuteteza kutayikira kwa slag ndi chitsulo chosungunula dziwe, kugwiritsa ntchito yokulirapo kuwotcherera mfundo ndi kuwotcherera malowedwe kukwaniritsa iwiri mbali kupanga.Kuwotcherera pamanja kwapang'onopang'ono kumizidwa ndi kuwotcherera kwa arc, kuwotcherera kwa seams omwe sangathe kugwiritsa ntchito liner, amatha kuwongolera kaye kachipangizo kenakake.kuwotcherera arc pansi pamadzi.Kuwotcherera pamwamba, popanda bevel, palibe kusiyana matako kuwotcherera, iye sagwiritsa ntchito liner msonkhano kusiyana zofunika kwambiri okhwima.Pofuna kuonetsetsa kuti kuwotcherera malowedwe, kuwotcherera kutsogolo kuti kuwotcherera kudzera 40 mpaka 50%, kumbuyo kuwotcherera ayenera kuonetsetsa kuti kuwotcherera malowedwe 60 mpaka 70%.Pochita nthawi zambiri zimakhala zovuta kuyeza kuya kwa kusungunuka, nthawi zambiri poyang'ana mtundu wa kumbuyo kwa dziwe losungunuka kuti muweruze ndi kulingalira, kuti mukhale ndi chidziwitso.Mipikisano wosanjikiza kumizidwa arc kuwotcherera, kwa mbale wandiweyani zitsulo ntchito Mipikisano wosanjikiza kuwotcherera pansi wosanjikiza mfundo kuwotcherera kukhala ang'onoang'ono, onse kuonetsetsa kuti kuwotcherera malowedwe, komanso kupewa akulimbana ndi zolakwika zina.Chigawo chilichonse cha zolumikizira zowotcherera ziyenera kugwedezeka kuti zisagwirizane.

Ukadaulo wowotcherera mphete ya matako

Thekuwotcherera arc pansi pamadzi wa matako mphete msoko wa silinda yozungulira ayenera kuchitidwa ndi tayala wodzigudubuza ndi chipangizo chowongolera liwiro.Ngati kuwotcherera mbali ziwiri kumafunika, cholembera cha flux chiyenera kuikidwa pakunja kwa khoma la silinda pansipa kuti mudutse koyamba.Konzani trolley yowotcherera pa chimango cha cantilever ndikufika pansi ku mbiya kuti muwotcherera lathyathyathya.Weld wire offset centerline pansi pa malo owotcherera otsetsereka.Kuwotcherera kwachiwiri kutsogolo kumachitidwa kunja kwa mbiya, kumtunda wapamwamba kuwotcherera.

Tekinoloje yowotcherera yolumikizirana

Pa ma T-joints ndi lap joints, njira ziwiri zowotcherera zooneka ngati ngalawa kapena kuwotcherera ma bevel angle nthawi zambiri zimagwiritsidwa ntchito, ndipo kuwotcherera kwa ngodya yosalala, ngodya yapakati pa waya ndi ukonde imasungidwa bwino pa 20 mpaka 30.°

Kulowetsedwa kwa arc semi-automatic kuwotcherera

Kuwotcherera kwa arc kumadzimadzi kumagwiritsidwa ntchito ndi waya wochepera 2mm, makamaka pakuwotcherera kwa fillet, komanso ma welds a matako.
