Kupu Whakataki
He kaihanga hiko waka hiko hou i whakaheke i te mokowhiti o te 1.8% ki te 0.05% me te whakanui ake i te kaha o nga hononga ma te 35% ma te arotau i nga tawhā toenga waiariki i roto i a raatau.pūnga hiko tuku welder. I tua atu, i raru tetahi tipu aerospace i nga moroiti i roto i nga waahanga koranu titanium na te ngoikore o te whakahaere i te waiariki, ka mutu, neke atu i te ¥3 miriona nga mate. Ko enei keehi e whakaatu ana ko te toenga waiariki kei rotopūnga hiko tuku welderKo nga punaha e pa ana ki te kounga paihere, te roanga o nga taputapu, me nga utu whakaputa. Hei tohu hangarau matua i roto i te whakahiato hiko, ko te toenga waiariki pumau e toru nga waahanga:te kaha o te hurihanga kaha (>92%), nga huarahi whakaheke wera(rerekenga pāmahana<±5°C), and te whakahaeretanga o te whakarereketanga o nga taonga. Ka tātari nahanaha tenei tuhinga e ono nga mea matua e awe ana i te toenga waiariki i rotopūnga hiko tuku weldermihini.

Patohia te pehanga: 400–600N (whakatairanga i te pakari o te nugget)
I whakaitihia e te kamupene hiko hou te whanuitanga o te wera-rohe (HAZ) ma te 40% me te pehanga servo katia-mana porowhita.
4. Pūnaha Whakamao Pai
4.1 Te Whakarerenga Wera Whakamaana Wai

Whakamutunga
I whakaitihia e te kamupene pākahiko hiko nga rerekee o te pāmahana fehokotaki mai i te ±25 tohu ki te ±3 tohu ma te whakamahi i te tauira mahanga mamati whakamaarama waiariki, ka tapahia nga reeti koha ma te 90%. He 99.99% te reiti tohu mo tetahi wae tiaki mo nga koranu teitei -whakarewa-me nga huringa huringa huringa algorithms. Ko nga raraunga e whakaatu ana ka taea e te whakahaere toenga waiariki te whakawhānui ake i te matapihi o te tukangapūnga hiko tuku weldernga punaha neke atu i te 40%. Ma te whakaurunga o te maha-whakaritenga ahupūngao me te mana urutau, kei te heke maipūnga hiko tuku welderka whakaatu nga mihini ki-te aroturuki i te rere wera o te waa, te utu tawhā hihiko, me te{1}}whakaritenga whakaora-e kawe mai ana i te wa o te mana waiariki nanoscale mo te whakapiri tika.
