Argon tungsten arc fehokotaki'anga whakamahi argon rite hau parepare ki te wera me te whakarewa i te rauemi fehokotaki'anga ake (ka rewa ano i te reira i te tāpiri i te whakarewa whakakī) i te tikanga o te pewa hangaia i waenganui i te hiko tungsten me te tinana weld, a ka hanga i te fehokotaki'anga. o te weld metal Way.Ko tetungsten electrode,Ko te puna kaukau, te pewa me te waahi tui hono kua whakamahanahia e te pewa ka tiakina mai i te poke o te hau e te rere argon.
I te wa o te whakahiato argon arc, ko nga tuunga o te rama, te whakarewa whakakii me te weldment ka rite ki te ahua o raro nei: ko te roa o te pewa ko te 1 ~ 1.5 nga wa te diameter o te hiko tungsten.Ka mutu te whakapiri, ka tangohia tuatahitia te whakarewa whakakī mai i te puna rewa (ka taapirihia te whakarewa whakakii kia rite ki te matotoru o te weldment), me noho tonu te pito wera ki raro i te maru o te rere argon kia kore ai e whakapouri. .
1. Welding rama (rama)
I tua atu i te awhi i te hiko tungsten me te tuku i te naianei fehokotaki'anga, me rehu hau parepare te argon tungsten arc fehokotaki'anga rama (e mohiotia ana ano ko te torch welding).Me whakamahi nga pu fehokotaki i naianei i nga pu whaowhao wai mo te wa roa.Na reira, he mea tino nui te whakamahi tika me te whakamarumaru o te rama raima.Ka whakaatuhia te kaha o naianei o te kawenga hiko hiko (A) i te ripanga i raro nei.
2. Ara hau
Ko te ara hau he mea tito i te pehanga argon cylinder reduction valve, te mita rere, te ngongo me te hiko hiko hiko (kei roto i te miihini whakapiri).Ka whakamahia te paera whakaheke pehanga hei whakaiti i te pehanga me te whakatika i te pehanga o te hau whakamarumaru.Ka whakamahia te mita rere ki te whakatikatika me te whakatika i te rere hau whakamarumaru.Ko nga miihini whakahiato Argon arc te nuinga o te waa ka whakamahi i te ine rerenga whakahekenga whakakotahi, he watea me te pono ki te whakamahi.
I te wa o te whakawhanaunga argon arc, ko te whakaritenga mo te maa o te hau argon ko te chromium-nickel kowiri tira kia ≥99.7%, me te whakarewa whakangao kia ≥99.98%.
(1) Ko te Argon he hau mokowhiti, a ehara i te mea ngawari ki te tauhohe me etahi atu mea whakarewa me nga hau.Ano, na te mea whakamahana o te rere o te hau, he iti te rohe e pa ana ki te wera o te weld me te iti o te huringa o te weldment.Ko te hau whakamarumaru tino pai mo te whakahiato arc tungsten argon.
(2) Ko te nuinga o te Argon e whakamahia ana ki te tiaki i te puna rewa, te aukati i te hau mai i te pakaru i te puna rewa me te whakapouri i te wa o te mahi whakaahuru, a i te wa ano ka pai te wehe i te hau i roto i te waahi weld, kia pai ai te waahi o te weld. ka tiakina, ka pai ake te mahi whakapiri.
(3) Ko te tikanga whakatikatika ka whakatauhia kia rite ki nga mea whakarewa hei paihere, te rahi o te waa, me te tikanga taapiri: ko te nui ake o te waa, ko te nui o te hau whakamarumaru.Mo nga rauemi huānga hohe, me whakakaha te hau whakamarumaru kia nui ake ai te rere.
3. Tawhā whakapūtātanga
Ko nga tawhā paerewa o te argon tungsten arc fehokotaki'anga te nuinga ngā o nāianei, ngaohiko, tere fehokotaki'anga, me te argon hau rere, me o ratou uara e pā ana ki te momo o te rauemi ki te kia paiherea, pereti matotoru me te momo hononga.
Ko nga toenga e toe ana penei i te roa o te hiko tungsten e puta mai ana i te puha he 1-2 nga wa te diameter o te hiko hiko, ko te tawhiti i waenga i te hiko tungsten me te weldment (te roa arc) he 1.5 nga wa te diameter o te tungsten. te hiko, ka whakatauhia te rahi o te puha i muri i te whakatau i te uara o naianei.Tīpakohia anō.
Ko nga korero whaanui whaanui argon arc kowiri tira e whai ake nei:
4. Te horoi i mua i te whakapiri
Tungsten argon arc fehokotaki'anga he tino tairongo ki te poke o te weldment me te whakakī mata whakarewa, na te hinu, paninga, whakahinuhinu me te waikura kiriata i runga i te mata o te weldment me nekehia atu i mua i fehokotaki'anga.
5. Hangarau haumaru
Ko nga kaihautu o te whaewhana arc argon tungsten me mau mahunga mahunga, nga karapu, nga kakahu mahi, me nga hu mahi hei karo i te wera ultraviolet me te infrared i roto i te pewa.Steyr tungsten argon arc fehokotaki mihini e rite rawa ki te tiketike-auau timata pewa.Ahakoa te iti o te kaha o te hiko hiko teitei e kore e wiri i te kaiwhakahaere, i te wa e kino ana te mahi o te whakamarumaru, ka wera te hiko hiko teitei i te kiri o te ringa o te kaiwhakahaere, a he uaua ki te rongoa, na reira ko te mahi whakamarumaru. o te kakau fehokotaki'anga me tirohia auau.I te wa o te whakahiato arc tungsten argon, me whakanui ake te hau i roto i te waahi whakapiri.
Tuhipoka: Ko te mea nui ko te mohio me te mohio.Ko te matotoru o te papa, te wa pao, me te au e pa ana, me mahi tahi raua.
I te wa e whakapiri ana, kaua e tohuhia te tohu ngira ki te waahi whakapiri i te timatanga, katahi ka paopao kia kore e puta te hau i roto i te paipa, kia kore ai e pupuhi te ngira, kia kore ai e puta he pango.He hēkona ruarua, penei, ka tiakina te kowiri tira e te hau argon i te wa e whakamahana ana, kia kore ai e pango, ka ora ano te wai horoi me te pepa whakakoi.Ka taea anake te whakamahi mo te whakapiri waahi.Mena ka toia e koe te raima mo te tawhiti, kaore he huarahi.Ka tino rereke te tae o te papa.Me tatari koe mo te oro me te horoi.
