Mig fehokotaki'anga - hohoro a pai

Fehokotaki'anga - Ko reira tukanga faito ore tuku tino tika, me te tika te mahi hononga tūturu wahi wāhanga o ngā tuhinga i hanga o konganuku rerekē ranei. Ki te rā, whakawhanakehia, ka whakatinana i roto i te hanga o te maha tikanga rerekē, me ngā tūāhua o te kakano ia hononga. Ia o nga tikanga he huapai me ngā huakore.

Ko tētahi o te hangarau fehokotaki'anga tino rongonui ko te fehokotakianga āhua-aunoa i roto i te whānuitanga o atmospheres hau paruru. Ka taea e te mahi te reira i ara nga tohunga ki tohu mātauranga raro atu i hiahiatia mō te fehokotaki'anga pewa ā-. I roto i tenei take, e te tukanga iti te wā. Ko te hua hangarau kaupapa Weld o kounga tiketike, me te e kore e rapua e murua muri i te para. Atu tukatuka (tämata, peita, me ētahi atu) paiherea taea te hanga hua whakaroa inati ki waho. Ko te whakamahi o te fehokotaki'anga hononga āhua-aunoa taea honotanga wahi whakarewa rawa kikokore (0.1 - 1.5 mm), te mahi honotanga he tui haere kaimono-pewa, hononga hapai i whānuitanga iti. Ko te reira i te tukanga fehokotaki'anga pai hoki-tauine iti ranei production papatipu.

Ko te ingoa "semiautomatic" tenei hangarau he rawa mo te waea. I roto i te meka, te reira te pewa taua kakano ia kawehiko waea motuhake kawea e te roto i roto i te hau e mangere. Ko te parau tumu i runga i hāngai te fehokotaki'anga āhua-aunoa, he tino māmā. whakaputaina e kai ana pūwhāngai kakano ia waea te ki te pūrere tangohanga, a ka - i roto i te rohe Weld. kaimahi pūrere mana taputapu motuhake ki te whakahaere i te tere waea kawehiko.

Tīmata i te tinana te mahi ngā taviri wā kotahi taua tuku o te hau, me te waea. I mua ki te timatanga o te wāhi tukanga tikanga tui o Weld ki tonu te ki te rere o te piringa motuhake. kawea excitation te pewa retireti haereraa i mua o te kawehiko haere nga taha papa paiherea ina te ngā i te kawehiko te ware, ka hono kē kai me te rere tonu ranei. I muri i patoto ua haapuai kawehiko matamata para, ki te keto te pewa te ka mura kotahi ano matou. Kei te nuinga o te tukanga kawea atu ki tauutuutu nāianei, ahakoa he taea hoki reira ki te whakamahi i pūmau.

Mig fehokotaki'anga - he tukanga wāhanga aunoa. hanga Moving te taata tei mau i te welder tui o e te ringa, i runga i tetahi taimaha ki te aro i runga i te tokotoko motuhake whakanohoia e te i runga i te hua. Whakamahia rite kai kawe, me te pahoho, tei te whiriwhiri i runga i te mahi fehokotaki'anga motuhake. Kua tīpakohia e te electrodes rite ki nga āhuatanga o te whakarewa paiherea me ngā āhuatanga Weld ki te kia whiwhi. Te hau paruru, kawea ai te te fehokotaki'anga i āhua tīpakohia hoki e hāngai ana i runga i nga āhuatanga o te maitai paiherea. Hoki iti maitai waro paruru hau hanga hauhā (CO _2), kia tono ai hauhauhā. tukua Gas te i te pupuha, displacing rangi i te wāhi fehokotaki'anga me te tiaki i te tui.

Na roto i te hoko i te taputapu fehokotaki'anga, e hiahia ana maha kaihoko ki te taea ki te whakaputa i me te kakano ia hoki konumohe. Nā ki te āhua o te whakarewa, he hangarau atu uaua atu i te pūhui o ngā hua maitai fehokotaki'anga āhua-aunoa o te konumohe. Fifi e pā ana ki tino rerekētanga o te pāmahana rewa o te konumohe (660 ° C) me te kiriata tiaki i runga i tona mata (2200 ° C). Tikina te kătahi kounga Weld me te pai āhua-aunoa i roto i te taiao hauhauhā he taea, engari i konei ka whakawhirinaki nga mea katoa i runga i te pūkenga, mahi me te pūkenga o te welder e mahi ana i te mahi.
