Kupu Whakataki
I roto i te fehokotaki'anga o ripa pākahiko mo waka pūngao hou, te whakamahi o matapae haukowhiowhio i roto iwelder wahi tuku capacitivekua piki ake te kaha o nga punaha ki te 40%. I taua wa, i tutuki i tetahi kaihanga parepare he kore-te kapohia o nga waahanga titanium angiangi-ma te whakamahi i nga matapaetanga hanga motuhake. Ko enei angitu e whakaatu ana ko te ahuahanga matapae he nui noa atu i te ahua hoahoa ngawari -e whakauru ana i te mana o naianei, te taurite whakamaarama, me te rheology rawa. Hei take matua e whakatau ana i te kounga paihere, ka whakaawe tika te ahua o te matapae i te kaha o te arotahi o te hiko (neke atu i te 92%) me te pumau o te poti. Ko tenei tuhinga e whakarato ana i te wetewete nahanaha o nga momo matapae nui e wha me o raatau tono ahumahi i rotowelder wahi tuku capacitivehangarau.
1. Nga Maapono Taketake: He pehea te Paanga o te Hanga Matapae ki te Kounga Weld
Matapae i rotowelder wahi tuku capacitiveka taea e nga punaha te tuku hiko aronga. Me tutuki i a raatau hoahoa nga whaainga e toru:
- Mana Kiato o Naianei: Whakapaihia te tohatoha me te karo i nga paanga taha (hapa<±5%).
- Ture Whakauru Wera: Whakatauritea te hanga poti me te wera -rohe kua pangia (HAZ).
- Te kaha o te kawe i te pehanga: Me whakarite kia rite te whakawhiti kaha (he rereke<±3%).

Papatahi mata<0.01mm
Tapa whakaawhiwhi R=0.05–0.2mm
- Uara Matua:
He pai te tohatoha pehanga (<±1.5% fluctuation)
He pai mo nga rawa -tekaeka (HRC Nui ake i te rite ranei ki te 40)
50% te whakapai ake i te pou-whakamutu mata

99% impedance hihiri tika ōrite ōrite
40% te whakapai ake i te rerenga rauemi
He tere ki te 120 welds/meneti
- Taupānga Motuhake:
Te whiri waea whiri waea ka taea
Nga hononga-a-taiao mo te raina wahie maru{0}}
3. Tikanga Whiriwhiri: E rima nga waahanga Whakatau Matua
3.1 Tauira Hototahi Rawa
| Momo Rawa | Te Matapae Manakohia | Kaupapa Hangarau |
|---|---|---|
| Kawenga teitei (Cu) | Hemiporo | Ka pehia te mararatanga o naianei |
| Te pakeke (Ti) | Papatahi | Ka karo i te kukū te ahotea |
| Maha{0}}apa/rereke | Motuhake -ahua | Ka taea te whakatikatika impedance hihiri |
3.2 Tātai Whakaōrite Mātotoru
Teitei Rawa H=0.2 × (t1 + t2) + 0.1mm
Hei tauira: Mo nga pepa konumohe 2mm + 1.5mm, he koeko kua tapahia me te H=0.8mm i eke ki te 5.2mm nugget (100% tautukunga).
4. Hunga -Te Hunga Whanaketanga Mata
- Whakawhiti Hanga Maramarama:
Te whakatikatika i te kopiko aunoa i runga i te matotoru rawa (whakautu<0.1s)
I whakauruhia e tetahi kaihanga Tiamana te hanga-whakawhiti hiko me te 6 ipurangi-kaahuri ka taea te huri, me te whakapai ake i te pai o te huringa ma te 80%.
- Te Hanganga Moroiti:
Taiaho -ahuatanga nanoscale kakano (Ra=0.05–0.2μm) ka whakaiti i te parenga whakapiri ma te 15% me te oranga hiko e toru.
- Hoahoa Kaupapa Hiato:
Tungsten-turanga parahi me te paninga taimana (50μm) ka mau ki te 800 tohu, ka taea te 800,000+ weera ki runga -te maitai teitei.
Whakamutunga
Ko tetahi kaihanga hiko hiko i whakaiti i te mokowhiti mai i te 0.5% ki te 0.02% ma te whakamahi i nga tohu motuhake -ahua, ka penapena neke atu i te ¥5 miriona ia tau mo nga utu rawa. I tutuki i tetahi hinonga aerospace he paihere pono o te pepa titanium 0.15mm, i whai waahi ki te 15% te hekenga o te taumahatanga amiorangi. Ko enei hua ka whakapumau ka piki ake te hoahoa matapaewelder wahi tuku capacitivemahi ki teitei hou. Ma te whakaurunga o te arotautanga topological me te hanga taapiri, ka whakaatuhia e nga matapaetanga a meake nei te whakarereketanga urutau, nga hangahanga moroiti ka taea te whakahaere, me nga rōnaki mahi-e iriti ana i te kaha ake mo te whakangao.
