Ko te hangarau honohono taiaho, te hangarau whakarewa taiaho rānei, e whakamahi ana i te hihi taiaho kaha teitei hei arotahi me te whakahaere i te whitinga o te mata o te rauemi, ā, ka mimiti te mata o te rauemi i te kaha taiaho ka huri hei kaha wera, ka wera ai te rauemi, ka rewa, ā, muri iho ka whakamatao me te whakapakeke kia tutuki ai te hononga o ngā rauemi ōrite, rerekē rānei. Ko te tukanga whakarewa taiaho e hiahia ana kia 10 te kaha taiaho.4ki te 108W/cm2Ki te whakatauritea ki ngā tikanga whakarewa tuku iho, ko ngā painga o te whakarewa taiaho e whai ake nei.

1-kapua plasma, 2-rauemi rewa, 3-kōhao kī, 4-hōhonutanga o te hanumitanga
Nā te mea kei te pū kōhao kī te hihi laser, i muri i te whitinga o roto o te pū kōhao kī, ka nui ake te mimiti o te laser e te rauemi, ā, ka whakatairanga i te hanganga o te puna rewa i muri i te marara me ētahi atu pānga, ka whakaritea ngā tikanga whakarewa e rua penei.
E whakaatu ana te pikitia i runga ake nei i te tukanga whakarewa taiaho o te rauemi kotahi me te pūtake mārama kotahi, ko te tikanga hurihanga pūngao ka mahia mā te kōhao kī anake, ka neke te kōhao kī me te konganuku rewa e tata ana ki te pakitara o te kōhao me te nekehanga whakamua o te hihi taiaho, ka nekehia te kōhao kī e te konganuku rewa kia matara atu i te hau e toe ana ki muri hei whakakī, ā, i muri i te whakatōtō, ka hanga he hononga whakarewa.
Mena he rerekē te rauemi e whakarewahia ana, ka nui te pānga o ngā rerekētanga o ngā āhuatanga wera ki te tukanga whakarewa, pērā i te rerekētanga o ngā ira rewa, te kawe wera, te kaha wera motuhake, me ngā tauwehenga whānui o ngā rauemi rerekē, ka hua ake te ahotea whakarewa, te whakarerekētanga o te whakarewa, me ngā huringa o ngā āhuatanga tioata o te konganuku hononga whakarewa, ka heke iho ngā āhuatanga miihini o te whakarewa.
Nō reira, e ai ki ngā āhuatanga rerekē o te wāhi whakarewa, kua whakawhanakehia e te tukanga whakarewa te whakarewa whakakī taiaho, te whakarewa taiaho, te whakarewa taiaho kurupae rua, te whakarewa hiato taiaho, me ētahi atu.
Te Whakakī Waea Taiaho
I roto i te tukanga whakarewa rēseri o te konumohe, te titanium me te parahi, nā te iti o te mimiti o te mārama rēseri (<10%) i roto i ēnei rauemi, he ārai motuhake te plasma i hangaia e te whakaahua i te mārama rēseri, nō reira he ngāwari te hanga i te tauhiuhi, ā, ka puta he hapa pērā i te porosity me ngā kapiti. Hei tāpiri, ka pāngia hoki te kounga o te whakarewa ina nui ake te āputa i waenga i ngā wahi mahi i te diameter ira i te wā e tauhiuhi ana te pereti angiangi.
Hei whakaoti i ngā raruraru o runga ake nei, ka taea te whiwhi hua pai ake mā te whakamahi i te tikanga whakakī. Ka taea te whakamahi i te waea, i te paura rānei hei whakakī, ka taea rānei te whakamahi i te tikanga whakakī kua whakaritea. Nā te iti o te wāhi arotahi, ka whaiti te whakakī, ā, ka paku pūkohu te mata i muri i te paninga o te rauemi whakakī.
Te Whakapūmau i te Taiaho
He rerekē tēnei i te whakarewa hanumi, e whakarewa ana i ngā wāhanga e rua i whakarewahia i te wā kotahi, ka tāpirihia e te whakarewa he rauemi whakakī he iti iho te ira rewa i te rauemi turanga ki te mata whakarewa, ka whakarewahia te rauemi whakakī hei whakakī i te āputa i te pāmahana iti iho i te ira rewa o te rauemi turanga, teitei ake hoki i te ira rewa o te rauemi whakakī, kātahi ka whakapūmau hei hanga i tētahi whakarewa totoka.
He pai te whakapūmau mō ngā taputapu hiko iti e tairongo ana ki te wera, ngā pereti angiangi, me ngā rauemi konganuku pupuhi.
I tua atu, ka taea te whakarōpū anō hei whakakā ngohengohe (<450 °C) me te whakakā mārō (>450 °C) i runga i te pāmahana e wera ai te rauemi whakakā.
Whakarewatanga Taiaho Kurupae Takirua
Mā te whakarewa kurupae rua-rama ka taea te whakahaere ngāwari me te watea i te wā me te tūranga o te hihi laser, ka whakarerekētia ai te tohatoha pūngao.
E whakamahia ana te nuinga mō te whakarewa taiaho o te konumohe me te konupora, te whakarewa hononga me te pereti taupoki mō ngā motuka, te whakarewa taiaho me te whakarewa honohono hohonu.
Ka taea te whiwhi i te hihi takirua mā te whakamahi i ngā taiaho motuhake e rua, mā te wehewehe hihi rānei me tētahi wehewehe hihi.
Ka taea e ngā hihi e rua te whakakotahi i ngā taiaho me ngā āhuatanga rohe wā rerekē (pāorooro me te haere tonu), ngā roangaru rerekē (ngā roangaru waenga-whero me te kitea) me ngā mana rerekē, ka taea te whiriwhiri i runga i te rauemi tukatuka tuturu.
4. Te Whakarewatanga Hiko Taiaho
Nā te whakamahinga o te hihi taiaho hei pūtake wera anake, he iti te tere tahuri me te tere whakamahinga pūngao o te whakarewa taiaho pūtake wera kotahi, he ngāwari te hanga i te he o te atanga tauranga rauemi turanga whakarewa, he ngāwari te hanga i ngā pore me ngā kapiti me ētahi atu ngoikoretanga, hei whakaoti i tēnei raruraru, ka taea e koe te whakamahi i ngā āhuatanga whakamahana o ētahi atu pūtake wera hei whakapai ake i te whakamahana o te taiaho i runga i te wahi mahi, e kiia ana ko te whakarewa hiato taiaho.
Ko te momo matua o te whakarewa hiato taiaho ko te whakarewa hiato o te taiaho me te pewa hiko, ko te pānga 1 + 1 > 2 e whai ake nei.
i muri i te hihi laser e tata ana ki te pewa kua whakamahia,kua tino heke te kiato irahiko, ka waimeha te kapua plasma i hangaia e te whakarewa laser, eka taea te whakapai ake i te tere mimiti o te taiaho, i te mea ka nui ake te tere mimiti o te taiaho mā te whakamahana mua i te pewa o te rauemi turanga.
2. te whakamahinga nui o te pūngao o te pewa me te tapekeka whakanuia te whakamahinga pūngao.
3, he iti te rohe mahi whakarewa taiaho, he ngāwari ki te hē te tauranga whakarewa, he nui te mahi wera o te pewa, ka taeawhakaitihia te hē o te putanga whakarewa. I taua wā anō, ko teka whakapai ake i te kounga me te whai huatanga o te pewa whakarewanā te pānga arotahi me te ārahi o te hihi taiaho ki te pewa.
4, he nui te pāmahana tihi o te whakarewanga taiaho, he nui te rohe e pāngia ana e te wera, he tere te whakamatao me te totoka, he ngāwari ki te whakaputa kapiti me ngā pore; he iti te rohe e pāngia ana e te wera o te pewa, ka taea te whakaiti i te pikinga pāmahana, te whakamatao, te tere totoka.ka taea te whakaiti me te whakakore i te putanga mai o ngā pore me ngā kapiti.
E rua ngā momo whakarewa hiato laser-arc e kitea whānuitia ana: te whakarewa hiato laser-TIG (e whakaaturia ana i raro nei) me te whakarewa hiato laser-MIG.
Kei reira anō ētahi atu momo whakarewa pērā i te whakarewa taiaho me te pewa plasma, te whakarewa taiaho me te whakarewa matū pūtake wera ā-whakaoho.
