He aha te mahi arc welding?

Electrode arc fehokotaki'anga ko te tikanga fehokotaki'anga tino whakamahia i roto i te hanga ahumahi.Ko te konganuku hei paihere he pou kotahi, ko te hiko ko tetahi atu pou.Ina tata nga pou e rua ki a raua, ka puta he pewa.Ko te wera i puta mai i te arc discharge (e mohiotia ana ko te arc combustion) ka whakamahia hei hono i te electrode me nga mea mahi ka rewa tetahi ki tetahi, ka hanga i te weld i muri i te whakamaaramatanga, kia whiwhi ai i te tukanga weriweri me te hononga kaha.

Whakaaturanga 1. Te hitori o te whakapiri

He korero poto

I muri i te maha o nga whakamatautau weriweri i te timatanga o te rau tau 1900, i whiwhi tuatahi tetahi tangata Ingarihi ko Willard te ingoa mo te whakahiato pewa i te tau 1865. I whakamahia e ia te hiko hiko ki te haere i roto i nga wahanga rino iti e rua kia pai ai te whakakotahi, a i te rua tekau tau i muri mai, he Ruhia. Ko Bernard te ingoa i whiwhi patent mo te mahi whakahiato pewa.I mau tonu ia i te pewa i waenganui i te pou waro me nga mea mahi.I te wa i whakahaeretia a ringatia ai te pewa i roto i te hononga o nga mea mahi, ka hono tahi nga mea mahi hei paihere.I te tekau tau atu i 1890, i hangaia te whakarewa totoka hei hiko, ka pau i roto i te puna rewa, ka uru ki roto i te whakarewa whakarewa.Heoi, ko te hāora me te hauota i roto i te hau i hanga he waikura kino me nga nitrides i roto i te whakarewa whakarewa., Ko te arahi ki te kounga fehokotaki'anga rawakore.

I te timatanga o te rautau 20, kua kitea te hiranga o te tiaki i te pewa ki te karo i te kuhu o te hau, a ko te whakamahinga o te wera arc ki te whakakore i te paninga ki roto i te hiko o te parepare hau whakamarumaru te huarahi pai rawa atu.I waenganui i nga tau 1920, i whakawhanakehia te electrode pania, i tino pai ake te kounga o te whakarewa.I te wa ano, tera pea ko te whakarereketanga tino nui o te whakahiato arc.Ko nga taputapu matua i roto i te mahi whakaahuru ko te miihini hiko, te kokopi me te kanohi kanohi.

Tikanga

Te pewa fehokotaki'anga te powered e te puna mana fehokotaki'anga.I raro i te mahi a tetahi ngaohiko, ka puta he ahuatanga whakaheke kaha me te wa roa i waenga i te hiko (me te mutunga o te waea whakapiri, te tokotoko ranei) me te taputapu mahi.Ko te tino o te pewa fehokotaki'anga ko te kawe hau, ara, te hau kupapaku i roto i te waahi kei reira te pewa ka pakaruhia ki roto i nga katote pai katoo pai me nga irahiko toraro i raro i te mahi a tetahi ngaohiko, e kiia nei ko te ionization.Ko enei matūriki utu e rua ka anga ki nga pou e rua.Ko te nekehanga o te ahunga ka whakahaere te hau o te rohe i te hiko kia puta ai he pewa.Ko te pewa hiko ka huri te hiko hiko ki te wera, ka whakamahana, ka rewa te whakarewa hei hanga i tetahi hononga paiherea.

I muri i te whakakorikori o te pewa ki te "whakaoho", ka taea e te tukanga tukunga ake te whakaputa i nga matūriki kua tohua hei pupuri i te tukunga, he ahuatanga tukunga whaiaro.A ko te tukanga tuku arc he iti ngaohiko, teitei o naianei, teitei teitei me te kaha o te rama.Ma tenei tukanga, ka huri te hiko hiko ki te wera, te miihini me te hiko marama.Ko te nuinga o te welding te whakamahi i tona hiko wera me te miihini ki te whakatutuki i te kaupapa o te hono konganuku.

I te wa o te whakapiri, ka wera te pewa i waenga i te kaitao me nga taputapu mahi, ka whakarewa i nga mea mahi me te matua hiko kia hanga he puna rewa.I te wa ano, ka rewa ano te paninga hiko, ka puta he tauhohenga matū ki te hanga i te para me te hau, e tiaki ana i te mutunga o te hiko, te pata, te puna rewa me te whakarewa wera wera.

Te whakarōpūtanga matua

Ko te nuinga o nga tikanga whakahiato pewa te nuinga ko te Wehenga Pounamu Maamaa (SMAW), te Wehenga Pounamu Rukuhia (SAW), te Wehenga Waehanga Tungsten Gas (GTAW, TIG ranei te Welding), te Waehere Pounamu Plasma (PAW) me te Waeherea Pewa Korehu Hau (GMAW，MIG or MAG ranei. ) etc.
