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.

 History of arc fehokotaki'anga-Tianqian

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 kukuti 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 ki te hanga 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 nga tikanga whakahiato pewa noa te nuinga ko te Wehenga Pounamu Whakaara (SMAW), Ko te Waahanga Pounamu Ruku (SAW), te Wehenga Pewa Tungsten Gas (GTAW ranei TIG fehokotakinga), te Wehenga Pounamu Plasma (PAW) me te Waeherea Peehe Korehu Hau (GMAW,MIG or MAG ranei. ) etc.

Ko te pewa kua rukuhia he tikanga e wera ai te pewa i raro i te paparanga rere mo te whakapiri.Ko te irahiko whakarewa e whakamahia ana i roto i te whakahiato pewa kua rukuhia he waea kore noa e whangaia ana ki roto me te kore e pakaru.I te nuinga o te waa, ka whakamahia he taakahu raima me etahi atu taputapu miihini me te hiko ki te mohio i te nekehanga aunoa o te pewa i te wa e mahi ana.Ka wera te pewa o te pewa karekau i raro i te rere kirikiri.Ko te wera o te pewa ka rewa, ka whakaeto i nga wahanga i mahia tikatia e te pewa o te mea mahi, te pito o te waea whakapiri me te rere, ka whakaeto te kohu o te whakarewa me te rere ki te hanga i te kohao kati huri noa i te pewa.Ka tahuna i roto i tenei rua.Kei te karapotia te kohao e te kiriata para i titoa mai i te para i puta mai i te rewanga rere.Ko tenei kiriata parapara ehara i te mea he pai te wehe i te hau mai i te pa ki te pewa me te puna rewa, engari ka aukati hoki i te pewa kia kore e puta.Ko te waea whakapiri kua werahia me te rewa e te pewa ka taka ki te ahua o te rūrūtia ka uru ki te whakarewa mahi whakarewa hei hanga i te puna rewa.Ka rewa te para iti ake i runga i te puna rewa.I tua atu i te wehenga miihini me te whakamarumaru o te whakarewa kaukau rewa, ka tukuna ano e te para whakarewa he tauhohenga whakarewa me te whakarewatanga o te puna rewa i te wa o te mahi whakapiri, na reira ka pa ki te hanganga matū o te whakarewa.Ka anga whakamua te pewa, ka whakamatao haere te whakarewatanga o te puna kaukau, ka maataata hei hanga i te wea.I muri i te whakamatao o te para whakarewa e maanu ana i te taha o runga o te puna rewa, ka hanga he kirinuku para hei tiaki tonu i te weld i te teitei o te wera me te aukati i te waikura.Ka whakaratohia e matou te rere mo SAW,SJ101,SJ301,SJ302

TIG-TianqiaoWhakaahua 5. Gas Tungsten Arc Weld-TIG

Gas Tungsten Arc Weld/Tungsten Inert Gas Welding (GTAW, TIG ranei)

Ko te whakahiato TIG e pa ana ki te tikanga whakaahuru arc e whakamahi ana i te tungsten, te koranu tungsten ranei (thorium tungsten, cerium tungsten, me etahi atu) hei hikohiko me te argon hei hau whakamarumaru, e kiia ana ko te TIG welding or GTAW welding.I te wa o te whakapiri, ka taea te taapiri i te whakarewa whakakii kaore ranei i te taapiri kia rite ki te ahua o te riu o te weld me te mahi o te whakarewa.Ko te nuinga o nga wa ka taapirihia te whakarewa whakakii mai i mua o te pewa.Na te mea motuhake o te konumohe-konupora me ona taonga koranu, ka hiahiatia te whakahiato arc tungsten AC mo te whakapiri, ka whakamahia te raima arc tungsten DC mo etahi atu mea whakarewa.I roto i te tikanga ki te whakahaere i te tāuru wera, pulsed argon tungsten arc fehokotaki'anga he ake me te ake whānui whakamahia.Te nuinga whakamahia TIG waea fehokotaki'anga heAWS ER70S-6, ER80S-G,ER4043,ER5356,HS221me etahi atu.

Plasma Arc Welding-Tianqiao Whakaatu 5. Plasma Arc Welding

Wehenga Pewa Plasma (PAW)

Ko te Plasma arc he ahua motuhake o te pewa.Ko te arc he tungsten, he koranu tungsten ranei (thorium tungsten, cerium tungsten, me etahi atu) hei hikohiko arc, ma te whakamahi i te argon hei hau whakamarumaru, engari kaore te hiko tungsten e toro atu ki waho o te puha, engari ka hoki ki roto i te puha, te puha. he mea whakamahana wai, e mohiotia ana ko te puha whakamahana wai.Ka wehea te hau inert ki nga wahanga e rua, ko tetahi waahanga ko te hau i puta i waenga i te hiko tungsten me te puha whakamahana wai, e kiia ana ko te hau katote;ko tetahi atu waahanga ko te hau i peia i waenga i te puha whakamahana wai me te kaapu hau whakamarumaru, e kiia ana ko te hau Shielding, ma te whakamahi i te plasma arc hei puna wera mo te whakapiri, te tapahi, te rehu, te papa, me era atu.
