Pūtaiao Rongonui o te Maven Laser | 10 Ngā Tikanga Whakarewa Noa
- Te Whakarewatanga Āwhata Whakamarumaru (SMAW)
Ko te whakarewa whakarewa āwhata tētahi o ngā pūkenga matua me matatau te kaiwhakarewa. Mēnā kāore i te tino matatau ki tēnei pūkenga, ka hua ake he maha ngā hapa i roto i te hononga whakarewa.
- Te Whakarewa Āwhata Ruku (SAW)
Ko te whakarewa pewa ruku he tikanga whakarewa e whakamahi ana i te pewa hiko hei pūtake wera. He hohonu te urunga, he nui te hua, ā, he pai rawa te kounga whakarewa: ka wehea te konganuku rewa mai i te hau mā te tiaki paru, ā, he tino mīhini te mahi, he pai mō te whakarewa i ngā hononga roa o ngā hanganga pereti reo me te matotoru.
- Wehenga Pewa Tungsten Hau (GTAW/TIG)
Anei ētahi whakatūpato matua mō te GTAW:
(1) Me whakakoi tonu te hiko tungsten kia angiangi. Ka puta he iahiko marara me te pewa kore pumau i te hiko pakari, ka pakaru te whakarewa.
(2) Ki te tata rawa te hiko tungsten ki te hononga whakarewa, ka piri ki te mea mahi; ki te tawhiti rawa, ka marara te pewa, ka mangu ngā whakarewa, ka tere te pakaru o te hiko, ā, ka kaha ake te pānga o te hihi ki te kai whakarewa. He pai ake te pupuri kia tata rawa atu.
(3) He pūkenga te whakahaere i te pūwero, inā koa mō te whakarewa pereti angiangi—he whakarewanga wāhi anake i roto i ngā wā poto. Kāore i rite ki ngā mīhini whakarewa aunoa me te waea whāngai aunoa me te neke, ka tahuna te whakarewa tonu i roto i te mea mahi.
(4) Me mārama te whāngai ā-ringa i ngā waea. Ka taea te tapahi i te waea whakarewa kounga teitei mai i ngā rau maitai kore waikura 304 mā te mīhini kutikuti hei utu mō te hoko waea kua takai mua; ko te waea kua takai mua, e wātea ana i ngā kaiwhakarato rarawe.
(5) Me mahi tonu i roto i tētahi wāhi e pai ana te hau, ā, me mau hoki he karapu hiako, he kākahu ātete mura, me te potae whakarewa e whakapouri aunoa ana.
(6) Whakamahia te pūwero uku o te rama whakarewa hei ārai i te mārama o te pewa—kia mau tonu te anga o muri o te rama ki tō mata i ngā wā katoa e taea ana.
(7) He mārama ā-roto, he matakite hoki tō te tohunga whakarewa mō te pāmahana, te rahi me te mahi a te pūahi rama o te puna whakarewa.
(8) Whakatakotoria te whakamahi i ngā irahiko tungsten kua tohua ki te kōwhai, ki te mā rānei, nā te mea e hiahiatia ana he pūkenga whakarewa teitei ake.
- Te Whakarewa Hau Oxy-Fuel (OFW)
Ka whakamahia e te whakarewa hau oxy-wahie he mura hei whakamahana i te konganuku turanga me te waea whakarewa i te hononga o ngā wahi mahi whakarewa, ka whakarewahia kia tutuki ai te whakarewa. Ko ngā hau wahie noa ko te acetylene, te hau hinu wai me te hauwai, me te hāora hei waikura matua.
- Te Whakarewatanga Taiaho
He tikanga whakarewa tino whai hua, tino tika hoki te whakarewa reera e whakamahi ana i te hihi reera kiato-pūngao teitei hei pūtake wera, ā, he tono matua tēnei o te hangarau tukatuka rauemi reera. I ngā tau 1970, i whakamahia nuitia mō te whakarewa rauemi angiangi me te whakarewa tere-iti. Ko te tukanga whakarewa he mea whakahaere e te ara iahiko: ka whakamahana te ira reera i te mata o te mea mahi, ā, ka horapa te wera o te mata ki roto mā te ara iahiko wera. Mā te whakahaere i ngā tawhā pēnei i te whānui o te pā o te reera, te pūngao, te mana tihi me te tere auau, ka rewa te mea mahi hei hanga i tētahi puna whakarewa motuhake.
- Wehenga Pewa Korehu Hau (GMAW/MIG/MAG)
He tokomaha ngā kaiwhakarewa e whakaaro ana ko te GMAW te tikanga whakarewa māmā rawa atu nā te mea he iti te arai urunga me te ngāwari ki te ako. I te nuinga o te wā, ka taea e te tauhou kāore he wheako whakarewa te mahi whakarewa tūranga taketake i muri i te 2-3 hāora noa iho o te ako mai i te tohunga.
Ngā kaupapa matua mō te ako i te GMAW: kia mau tonu te ringa, kia matatau ki te whakarerekē i te au me te ngaohiko, kia whakahaere i te tere whakarewa, kia ako hoki i ngā nekehanga ringa tika (he ngāwari te ako mā te mātaki i ngā akoranga ataata). Mā te matatau ki te raupapa whakarewa ka taea e koe te whakahaere i te nuinga o ngā mahi whakarewa.
- Te Whakarewatanga Waku
Ko te whakarewa waku he tikanga e whakamahi ana i te wera e puta mai ana i te waku i ngā mata pa o ngā wahi mahi hei pūtake wera, ka puta te āhua kirihou o ngā wahi mahi i raro i te pēhanga hei whakatutuki i te whakarewa.
I raro i te pēhanga me te taipana pumau, e piki haere ana rānei, ka puta te wera waku me te wera āhua kirihou i runga me te taha o te mata waku nā te nekehanga whanaunga i waenganui i ngā mata pito o te hononga whakarewa, ka piki ake te pāmahana o te wāhi ki te awhe tata ki te ira rewa engari i raro iho i te nuinga o te wā. Ka whakaitihia e tēnei te ātete āhua o te rauemi, ka whakanui ake i te āhua kirihou, ā, ka pakaru te kiriata waikura i te atanga. I raro i te pēhanga whakakorikori, me te āhua kirihou me te rere o te rauemi, ka tutuki te whakarewa mā te horapa i waenga i ngā ngota me te whakakōkī anō i te atanga—ka waiho hei tikanga whakarewa āhua totoka.
Ko te whakarewa waku e whā ngā taahiraa: (1) te huri i te pūngao miihini ki te pūngao wera; (2) te whakarerekētanga kirihou o te rauemi; (3) te whakakorikori i te pēhanga i raro i ngā āhuatanga thermoplastic; (4) te horapa i waenga i ngā ngota me te whakakōkī anō.
- Te Whakarewatanga Ultrasonic
Ka tukuna e te whakarewa ultrasonic ngā ngaru wiri auau-teitei ki ngā mata o ngā wahi mahi e rua hei whakarewa. I raro i te pēhanga, ka mirimiri ngā mata e rua tetahi ki tetahi hei hanga i te hanumitanga i te paparanga ngota. Ko te pūnaha whakarewa ultrasonic katoa he mea hanga mai i te whakaputa ultrasonic, te whakawhiti hiko, te haona, te huihuinga pito whakarewa, te pokepokea ai me te anga.
- Te whakapiri ngohengohe
Ko te whakakoi me te whakapiripiri ka whakamahia he konganuku whakakī he iti ake te ira rewa i te konganuku turanga. Ka whakamahanahia ngā wahi mahi me te konganuku whakakī ki te pāmahana kei runga ake i te ira rewa o te whakakoi engari kei raro iho i te ira rewa o te konganuku turanga. Ka whakamakuku te konganuku whakakī rewa i te konganuku turanga, ka whakakī i te āputa hononga ka horapa ki te konganuku turanga kia tutuki ai te hononga wahi mahi. He iti noa te whakarerekētanga o te ahua o te whakakoi me te whakapiripiri, ā, he maeneene, he ātaahua ngā hononga, e pai ai mō te whakapiripiri tika, ngā wāhanga uaua me ngā huihuinga i hangaia mai i ngā rauemi rerekē (hei tauira, ngā panera honikoma, ngā mata tāpoi, ngā taputapu tapahi karawiti sima me ngā papa ara iahiko tā). I runga i te pāmahana whakapiripiri, ka wehea te whakapiripiri me te whakapiripiri kia rua ngā wāhanga: ko te tukanga me te pāmahana whakapiripiri i raro i te 450℃ ka kiia ko te whakapiripiri ngohengohe, ā, ko te mea kei runga ake i te 450℃ ka kiia ko te whakapiripiri mārō.
