Fehokotakianga Electroslag: te momo, me te āhua

ngā mahi fehokotaki'anga ki konganuku e te nuinga i runga i te tukanga rara matū-waiariki. Tei runga i te tooling whakamahia, nga Whakapau kaha, me te whakahaere tikanga hangarau o nga tikanga tukanga, me te huri āhuatanga o te hua hua. Ko te mahi matua o te welder ko ki te hanga i te tahi roa e taea te tu i te kawenga i e hinga ano i runga i te hanganga matua. I roto i te faatura i tenei, e kore he fehokotakianga electroslag te otinga pai e wātea ana i tenei ra kia rite ki te puāwaitanga rongo pewa hiko taea te hanganga o atu pai mo te mahi atu o nga kaimono. Heoi, ko te whakamahi o te para pati ki te ngohe tukanga whakarato maha atu painga mo e whakamahi te kamupene nui tenei hangarau.

WHAKARĀPOPOTOTANGA fehokotaki'anga electroslag

Tikanga o te electroslag fehokotaki'anga i runga i te tono o te wera i hanga nei i roto i te rauemi rewanga. Ko te hua waiariki pūngao, me te reira mahi he take e whakarato ana i te mahi fehokotaki'anga. Ka rite ki te rauemi whakarewa nei, i raro te, para whakamahia pūtake. Ko te māngai pūtake o te tukanga rewanga ko te nāianei hiko, na he generator motuhake e whakamahia ana i roto i te tukanga o te whakahaere. Ko te āhuatanga motuhake o te tukanga ngā te meka e taea te whakamana i te fehokotaki'anga electroslag anake i roto i te preforms whakanohonga poutū. I raro i te mana o te wera i hanga whakarewa wai, i hanga nei i roto i waea kawehiko Reflow āhuatanga ka paiherea me whakakiia ana te wāhi i waenganui i te wāhanga. Hei pupuri i te wai para, me te whakarewa pati i te waipuke nui, me ngā rōpū rerekē te mahi pati whakaturia kiriata wai mātao. Ka rite ki te tui fehokotaki'anga e whakaarahia ratou, a kahore e hoatu e te rere papatipu mahi.

tukanga

E haamata te reira ki te tukanga excitation pewa fehokotaki'anga, ka e kia hanga e i waenganui nga wahi me nga waea kawehiko. Ko te pūngao waiariki o te pewa rewa te rere, a ka hangaia e te pati para rawa, te taumata o e ka e whakaarahia. Nā ki te taonga o te kawe ia hiko, tīmata rere tauta ki whakanekeneke te pewa, tu tona tahunga. A, no te tonu tenei rewa me whakawera rere tika ki ngā pānga waiariki, i tukua puna nāianei mahi ki te para wai. Ko, he tukanga electroslag fehokotaki'anga i runga i te whakawhitinga o te wera i te para, engari tuku anake pūngao i te nāianei, engari ano hoki e taea tika whakawhiti ona wahi mahi.

Ko te kawehiko me te ūnga whakarewa, e toaati e tikanga o rite te pati para. Kei te muri i hanga me te pati whakarewa. kia rapua e tenei wā rerekē, i runga i te āhuatanga rauemi rānei. Ko te mea nui, ko te e te turanga whakarewa wai kei i te taumata o raro o te pati para, engari titau hoki he niao hononga rēreti tutakina rawatia leakage. Hoki tenei whakaaro, nga rēreti o parahi, i hū ki te wai.

momo o te fehokotaki'anga

Huarahi ki te whakatinana i tenei tikanga rerekē i roto i te momo o te kawehiko whakamahia. Hei tauira, te kaupapa puāwaitanga whai wāhi te whakamahi o te waea fehokotaki'anga whangai nei rite ngohe ki te pati para. I roto i tenei huarahi, me whakamōhio te ariki te electrodes reciprocating hoki nekehanga whakapae, e whakarato ana whakawera ōrite o te wahi paiherea puta noa te matotoru.

Ko tā tētahi atu tikanga te whakamahi o electrodes ki wāhanga ripeka nui mau api ranei. I roto i tenei take, ka noho i te kawehiko te nuinga o te wāhi i hanga e te āputa i waenganui i te workpieces. horahia ano mau api Mā te. I roto i te taua fehokotaki'anga kaupapa electroslag kawea i roto i ki te tumanako o te reta ahu o kaha huānga taipitopito. Heoi, kia rite ki te workpiece paiherea ratou āhua. Ka taea te tukua te pereti āputa whakaritea whakapakari i a i runga i te āhua o te pati para rānei ki te wāhi mahi kia rite ki te mahi.

taputapu fehokotaki'anga

Ka rite ki ki whakaū hiko tikanga, i roto i tenei take, he taputapu motuhake. Hei whakatau ona āhuatanga kia tuhia te reira e te tikanga electroslag, pērā kia whakatinana ai i ētahi atu tikanga fehokotaki'anga noa ki te kiato o nāianei 0.1 A / mm ^2, i te mea iti atu i hoki te tikanga pewa taua rau o nga wa o. No te faatupu i tenei mahi mā te whakamahi i mihini e ōrite ana ki ngā paearu maha. Ko te tikanga tuatahi, ko te ki te whakarite kia te āputa i waenganui i nga taha rerekē o te tāpu. kitea te huru tuarua i roto i te meka e kia tukua te taputapu mō te fehokotaki'anga electroslag te hanganga o te tui paiherea poutū. Na te nui huru whakamutunga ko e me kawea fehokotaki'anga i roto i te huarahi kotahi. Ka rite ki te whakamahia hoki te taputapu atu awa kai waea, kiriata mängai o nāianei-tuku ki kaho, me ngongo mo te wai te meangiti.

fehokotaki'anga Whakapau

Ko te turanga kaha mo te taua fehokotaki'anga - ka mea te reira electrodes, e taea whai rave rahi tuaka whakaritea. whakaratohia kai ki te pati para te i te tere aumou. I tua atu kia hoki te whakamahi para me electrodes rewa auvaha parau. Tei runga i te whakaritenga ki te farii i hua, te operator e taea te whakahaere i te Whakapau penei e ka kia kawea te tukanga i roto i ki rerekē nekehanga o te kaha - Kei te hanga hoki te ako mo te whawhe ki te taua electrodes ki te whakapai ake i mahana ki whakaaro ki te momo o te whakarewa. Ko te tikanga, i te tirohanga o te uaua ki te ariki, uaua atu te tukanga o te electroslag kakano ia ki te parau tumu whakapā puaretanga. Tikanga, tono para-whakapā technique te i roto i te wā i te mea e tika ana ki te Weld kaho ki te mata planar.

painga o te hangarau

Ko tētahi painga nui o te tikanga ko te kaha ki te Weld i waho te hiahia mō te wehenga mua o nga taha, i kite hoki te tukanga e te aroaro o te āputa i waenganui i nga wahi mahi o runga ki te 3 cm. Kakano ia ano electroslag he whakarea nui o fehokotaki'anga, e hua i roto i, me hua pūtea rite penapena i roto i te whakahaere hui. Ka kia ua Hua i muri i te otinga o te mahi. Ko te take i tenei momo o te fehokotaki'anga whakarato te whakaritenga hangarite o te whanaunga tahi ki te tuaka. Tenei take ārai te hanganga o te deformation koki, e te mutunga ohie te tāutanga o ngā wāhanga ki ratou whakarerekētanga.

Mara o te tono

tautuhia te taea o te whakamahi i tenei tikanga te rite te wa, me ona tōnounoú. He koretake ki te whakamahi i roto i te nuinga o te fehokotaki'anga momo tenei tikanga. Nuinga o ngā wā, whai wāhi hangarau i roto i te hanga me te tono ahumahi. Hei tauira, te hanga o te anga nui, te tāutanga o te taputapu mīhini huri hiko, te tāutanga o pahu matotoru-taiepa, me ngā waeine kōhua - he wāhanga noa o te ngā mahi noa i roto i i whakamahia te fehokotaki'anga hiko-para te tenei. Taupānga o tenei tikanga i roto i te hanga taea ki te huihui hanganga nui. Ko te tino rerekētanga i waenganui i nga tikanga electroslag i ētahi atu tikanga o te mōhiohio huānga konganuku ko ki tukua te taea o whakakapi titoa ranei paiherea maka wahi ritenga nui, i hanga o castings iti ranei forgings.

mutunga

Hoki te momo o take, ara i roto i nga wāhi ūnga o tenei hangarau kore e whakaaetia tonu tona whakamahi. Kei te nuinga Rāhuitanga e pā ana ki te mau hapa hangarau e hanga whakamahi o te tikanga koretake. Hei tauira, ka kia whai hua hiko-para fehokotaki'anga ki te whakaritea ai ki te whakamahi i runga i te pae, te wahi i reira e tairongo ki rauemi ahotea waiariki hoki. Ko, hoki take ōhanga, me te mea e tika ai te kounga o te hangarau atanga, engari i reira he tetahi mita. he rohe fehokotaki'anga taua āhuatanga e mana waiariki teitei, aua, i roto i te whakaritenga tū o ngā tūemi rauemi e pā ana katoa ki a ratou, ka riro ai ki ngā pānga kaha waiariki.
