Te Putanga o te Hau Tiaki

Tuatahi, ko te pupuhi o te hau whakamarumaru
I tenei wa, e rua nga tikanga pupuhi o te hau whakamarumaru: ko tetahi he hau whakamarumaru taha-paraxial, e whakaatuhia ana i te Whakaahua 1;I te nuinga o te waa, e taunaki ana kia whakamahia te pupuhi taha ki te tiaki i te hau

Rua, te hau tiaki hau pupuhi tikanga whiriwhiri parau tumu
Tuatahi, me maarama ko te mea e kiia nei ko te weld he "oxidized" he ingoa noa.Ko te tikanga, e pa ana ki te tauhohenga matū i waenga i te weld me nga kai kino o te hau, e pa ana ki te kino o te kounga o te weld.He mea noa kia tauhohe te konganuku weld ki te hāora, te hauota me te hauwai i te rangi i tetahi pāmahana.
Ki te aukati i te weld kia kore e "oxidized" ko te whakaiti, te karo ranei i te pa atu o aua kai kino ki te whakarewa i roto i te ahua teitei o te pāmahana.Ko tenei ahuatanga teitei o te pāmahana ehara i te mea ko te whakarewatanga o te puna rewa anake, engari ko te wa katoa o te waa mai i te wa e rewa ai te whakarewa o te whakarewa ki te whakamaaramatanga o te whakarewatanga o te poka wai, ka heke tona pāmahana ki tetahi pāmahana i raro nei.
Toru, tango tauira.
Hei tauira, ko te koranu koranu Titanium, ka eke te pāmahana ki runga ake i te 300 ℃ ka tere te tango i te hauwai, neke atu i te 450 ℃ ka tere te tango i te hāora, neke atu i te 600 ℃ ka tere te tango hauota, na reira ko te titanium koranu koranu tui i muri i te pakaritanga me te whakaheke i te pāmahana ki te 300 ℃ i raro i tenei waahanga me whai hua te whakamarumaru, ki te kore ka "whakaora".
Mai i te whakaahuatanga i runga ake nei ehara i te mea uaua ki te maarama, ko te whakamarumaru o te hau e pupuhi ana ehara i te mea tika ki te tiaki i te kaukau rewa te weld, me pai ano hoki kia paiherea te waahi tio noa o te whakamarumaru, na reira ka mau te paraxial e whakaatuhia ana i te ahua 1 te taha tiaki. hau, no te mea tenei ara e pa ana ki nga huarahi ki te tiaki i te awhe whakamarumaru o te ara whakamarumaru coaxial o te ahua 2 he whanui ake, Ina koa mo te weld kua whakamaroke noa he pai ake te whakamarumaru.
Ko te pupuhi taha paraxial mo nga tono miihini, kaore e taea e nga hua katoa te whakamahi i te hau whakamarumaru i te taha o te taha rakau, mo etahi hua motuhake, ka taea anake te whakamahi i te hau whakamarumaru coaxial, nga hiahia motuhake mai i te hanganga hua me te whiriwhiringa kua tohua.
E wha, kowhiringa aratau pupuhi hau whakamarumaru motuhake
1. Wero tika
Ka rite ki te Whakaaturanga 3, he raina tika te ahua o te wea o te hua, a ko te ahua o te hononga he hononga reke, he hononga hiku, he hononga kokonga kino, he hononga īnaki ranei.Mo tenei momo hua, he pai ake ki te tango i te taha taha ki te pupuhi i te tikanga hau whakamarumaru e whakaatuhia ana i te Whakaahua 1.

2. Paetahi katia whakairoiro paiherea
E whakaatu ana i te Whakaahua 4, ko te ahua weld o te hua ko te ahua porohita porohita, te hanga rererangi maha, te ahua raina-waahanga rererangi me etahi atu ahua kati.Ko te ahua o te hononga ka taea te hono reke, te hononga hiku, te whakapiri inaki me etahi atu.Mo tenei momo hua, he pai ake te tango i te aratau hau whakamarumaru coaxial e whakaatuhia ana i te Whakaahua 2.

Ko te kowhiringa o te hau whakamarumaru ka pa tika ki te kounga o te raima, te kakama me te utu o te whakaputa, engari na te rereketanga o nga rawa whakakao, i roto i nga mahi whakaahuru, he uaua ake te kowhiringa o te hau whakaahuru, me whai whakaaro nui ki nga rauemi whakahiato, tikanga whakahiato. , te tuunga whakaahuru, me nga whakaritenga o te paanga whakaahuru, na roto i nga whakamatautau whakahiato ki te whiriwhiri i nga mea e pai ake ana mo te weriweri hau, kia pai ake nga hua.
