Karere - E hia nga momo welding laser e mohio ana koe?（2）

3 Taiaho rere fehokotaki'anga

(1) Tikanga

Ko te Welding on Fly ka kiia ko te welding laser mamao, ko te karetao matawai taiaho ranei.Ko te whakauru i te upoko matawai whakaata tere tere ki te tuaono o te karetao, me te mohio ki te nekehanga ara taiaho na roto noa i te whakaata hurihuri whakaata, kaore he ringa karetao e whai ana i te nekehanga.Ko te punaha whakahiato mamao laser he tino ngawari me te pai ake i te raima laser noa.Ka taea e te huinga o te punaha te whakakapi i nga huinga 6 ~ 9 o te raima waahi karetao noa.Ko te tawhiti i waenga i te mahunga taiaho me te taputapu mahi ka neke atu i te 500mm, ka taea te whakaroa i te oranga o te karaihe tiaki arotahi.He rite tonu te maataapono o te mahi ki tera o te whakakotahitanga, ko te ahua o te papa pereti.Ko te Whakaaturanga 1 e whakaatu ana kei te whakamahi te kuaha i te raima rererangi.

(1) Nga waahanga

Ki te whakatauritea ki te whakahiato tuku iho, ko te painga nui rawa atu o te weriweri mamao taiaho ko te mea ka taea e ia te whakapai ake i te pai o te whakaputa.Ko te tere o te nekehanga o te arotahi o te upoko matawai ka tino whakaitihia te wa e whakamahia ana ki te kimi i te kaikokoti, na reira ka tino whakaitihia te waa mahi.Whakaritea ki te tere toharite o 0.5 tohu fehokotaki'anga / s o te ātete wahi fehokotaki'anga, te tere fehokotaki'anga ko 3-4 tohu fehokotaki'anga / s, hanga whakamahi tonu o te kurupae taiaho.Na roto i te whakamatautau whakaputa papatipu, ka whakatauritea ki te weriweri waahi aukati tuku iho, ka taea te whakapoto i te wa o te welding mamao taiaho e 80%.

Ki te whakatauritea ki te weriweri waahi tuku iho, ka taea e te weriweri rere taiaho te whakarite i te ahua weld, te arotau i te ngawari o te hoahoa whakapiki kaha o te weld, a ka taea te tono ki tetahi ahua weld me tetahi ahunga weld.Ko te ahua 2 e whakaatu ana i te whakatairitetanga i waenga i te raima waahi tuku iho me te raima rererangi laser.

(1) Te waahi tono

I tenei wa, kei te whakamahia te nuinga o te raima rererangi laser mo nga tatau o te motuka, te whakatuwhera i nga tatau o te pakitara taha me etahi atu waahanga me nga tohu whakapiri (e hiahia ana ki te pai o te raima) me nga whakaritenga kawenga iti.Whakaatu 3 whakaatu te rohe fehokotaki'anga rere taiaho o Ford Mustang.
