Whakamātautau Whakauru Kurupae H (PT) 316L maitai kore waikura i whakarewaina
I ahu mai i te JBT 6062-2007 Whakamātautau kore-whakangaro - whakamātautau werohanga o ngā whakarewa mō te kurupae H maitai kore waikura 304L 316L.
He aha ngā tikanga whakarewa?
Ko ngā tikanga whakarewa ko te whakarewa pewa, te whakarewa pare hau (whakarewa MIG/MAG), te whakarewa ātete, te whakarewa taiaho, te whakarewa pewa plasma, te whakarewa whakaoho waku, te whakarewa pēhanga, te whakarewa hihi irahiko, me ētahi atu. He tono me ngā āhuatanga motuhake o ia tikanga, e tika ana mō ngā momo mahi rerekē me ngā whakaritenga whakaputa. Ka whakamahia te pewa hei whakaputa i ngā pāmahana teitei, te whakarewa i te konganuku i runga i te mata o te mahi hei hanga hononga. Ko ngā tikanga whakarewa pewa noa ko te whakarewa pewa ā-ringa, te whakarewa pewa argon, te whakarewa pewa ruku, me ētahi atu. Ko te wera i puta mai i te ātete ka whakamahia hei whakarewa i te konganuku i runga i te mata o te mahi hei hanga hononga. Kei roto i te whakarewa ātete te whakarewa ira, te whakarewa hononga me te whakarewa pūtu.
I ngā wā katoa e taea ai, me mahi ngā whakarewa i roto i te toa mahi, kei reira te kounga o te whakarewa e pai ake ana. Kāore ngā whakarewa i roto i te toa mahi e pāngia ana e te huarere, ā, he tuwhera te urunga ki te hononga. Ka taea te whakarōpū i ngā whakarewa ki te papatahi, te whakapae, te poutū, me te runga. Ka kitea ko ngā whakarewa papatahi te mea ngāwari ki te mahi; koinei te tikanga e pai ake ana. Me karohia hoki ngā whakarewa i runga, e mahia ana i te mara, i ngā wā katoa e taea ai nā te mea he uaua, he roa ake te wā, ā, he nui ake te utu.
Ka taea e ngā whakarewa awaawa te wero i te mema hono mō tētahi wāhanga o te matotoru o te mema, ka taea rānei te wero i te matotoru katoa o te mema hono. Ka kiia ēnei ko te wero hononga wāhanga (PJP) me te wero hononga-katoa (CJP). Ko ngā whakarewa wero katoa (e kiia ana ko ngā whakarewa wero katoa, "pene-katoa" rānei) e whakakotahi ana i te hohonutanga katoa o ngā pito o ngā mema hono. He iti ake te utu o ngā whakarewa wero wāhanga, ā, ka whakamahia ina he nui ngā kawenga e pā ana, ā, kāore e hiahiatia he whakarewa wero katoa. Ka taea hoki te whakamahi ina he iti noa te urunga ki te awaawa ki tētahi taha o te hononga.

He aha ngā painga o te whakarewa pewa ruku?
He pai te whakarewa pewa ruku mō ngā taiao aunoa me ngā taiao nui-rahi. Ka taea e ia te whakaoti i te nui o ngā mahi whakarewa i roto i te wā poto, ā, ka whakapai ake i te pai o te whakaputa. He pai te whakarewa pewa ruku mō ngā taiao aunoa me ngā taiao nui-rahi. Ka taea e ia te whakaoti i te nui o ngā mahi whakarewa i roto i te wā poto, ā, ka whakapai ake i te pai o te whakaputa. Ko te whakarewa pewa ruku te tikanga e whakamahia ana hei whakarewa i ngā pepa whakarewa matotoru ake nā te mea he nui te iahiko me te urunga nui ka pai ake te whai hua i roto i ēnei mahi. Nā te mea kua kapi te whakarewa i te rere, ka taea te ārai pai i te hāora kei uru ki te wāhi whakarewa, ā, ka whakaiti i te tūponotanga o te waikura me te ruirui. Ki te whakatauritea ki ētahi tikanga whakarewa ā-ringa, he maha ngā wā ka taea te aunoa i te whakarewa pewa ruku, ka whakaiti i te nui o ngā tono ki ngā pūkenga kaimahi. I roto i te whakarewa pewa ruku, ka taea te whakamahi i ngā waea whakarewa maha me ngā pewa i te wā kotahi hei whakatutuki i te whakarewa maha-awa (maha-paparanga) me te whakapai ake i te pai.
He aha ngā whakamahinga o ngā kurupae H-kowiri tira?
He whānuitia te whakamahinga o ngā kurupae H kowiri tira i roto i ngā mahi hanga, te miihini moana, ngā taputapu ahumahi, ngā motuka, ngā kaupapa pūngao, me ētahi atu mara nā te mea he ātete ki te waikura me te roa. Ka tautoko i ngā hanganga i roto i ngā kaupapa hanga, ā, he mahi nui tā rātou i roto i ngā taiao e hiahia ana kia ātete ki te waikura, pērā i ngā taiao moana, ahumahi rānei. Hei tāpiri, nā te āhua hou me te ātaahua e pai ai mō ngā mahi hoahoa whare me ngā mahi hoahoa ā-roto.
Kia pēhea te tika o te kurupae HI Kowiri tira?
Ko te tika o te kurupae-H kowiri tira, pērā i ngā wāhanga hanganga katoa, he mea nui mō tōna mahi me te tāutanga. I te nuinga o te wā, ka hangaia e ngā kaihanga ngā kurupae-H kowiri tira me tētahi taumata tika kia tutuki ai ngā paerewa me ngā whakaritenga ahumahi.
Ko te paerewa ahumahi kua whakaaetia mō te tika o te maitai hanganga, tae atu ki ngā kurupae-H o te maitai kore waikura, ka tautuhia i runga i ngā rerekētanga e whakaaetia ana mai i tētahi rārangi tika i runga i tētahi roa kua tohua. Ko tēnei rerekētanga ka whakaatuhia i roto i ngā mirimita, i ngā inihi rānei o te nekehanga taha, te nekehanga taha rānei.
He kupu whakataki ki te āhua o te hihi H?
Ko te āhua whakawhiti-wāhanga o te maitai kurupae-I, e mōhiotia whānuitia ana ko "工字钢" (gōngzìgāng) i te reo Hainamana, he rite ki te reta "H" ina whakatuwheratia. Ina koa, ko te whakawhiti-wāhanga he mea hanga ki ngā pae whakapae e rua (ngā flanges) i te tihi me te raro, me te pae waenga poutū (whatunga). Mā tēnei āhua "H" ka nui ake te kaha me te pumau ki te maitai kurupae-I, ka waiho hei rauemi hanganga noa i roto i te hanganga me te miihini. Mā te āhua hoahoa o te maitai kurupae-I ka taea te whakamahi mō ngā tono kawe kawenga me te tautoko, pērā i ngā kurupae, ngā pou, me ngā hanganga piriti. Mā tēnei whirihoranga hanganga ka taea e te maitai kurupae-I te tohatoha pai i ngā kawenga ina pāngia e ngā kaha, ka whakarato tautoko pakari. Nā tōna āhua ahurei me ōna āhuatanga hanganga, ka kitea te whakamahinga whānui o te maitai kurupae-I i roto i ngā mara o te hanganga me te miihini.
