I roto i te mara o te whakarewa hanganga me te ahumahi, he mea nui te whiriwhiri i ngā rauemi whakakī tika hei whakarite i te pumau me te mahi o ngā hononga.Irahiko Whakarewa Waro RinoHe mea taketake te kāwai, e kapi ana i ngā momo rerekē kua hangaia hei whakatutuki i ngā whakaritenga miihini me ngā whakaritenga tikanga. I roto i ēnei, ko te AWS E7015, e kiia ana hoki ko te tauira 507 i ētahi rohe, he hiko iti-hauwai e whakamahia whānuitia ana mō ngā tono maitai waro nui.
Ko te āhuatanga matua o tēnei Irahiko Whakarewa Waro motuhake ko tōna paninga konutai hauwai-iti. He mea nui tēnei hanganga paninga hei whakaiti i te whakaurunga o te hauwai ki roto i te konganuku whakarewa, e whakaiti nui ana i te tūponotanga o te pakaru i puta mai i te hauwai, inā koa i roto i ngā wāhanga matotoru ake, i raro rānei i ngā āhuatanga kua whakawhāitihia. He tino pai te kirihou, te pakari, me te ātete pakaru whānui o te konganuku kua whakatakotoria, e pai ai mō ngā taiao uaua e tino hiahiatia ana te pono o te hanganga.
Mai i te tirohanga whakahaere, ko tēneiIrahiko Whakarewa Waro Rinome whakamahi i te taura hiko DCEP (Direct Current Electrode Positive). Mā tēnei āhuatanga hiko ka hohonu te urunga me te pewa pumau. He mea nui, kua hangaia te hiko mō te whakarewa i ngā tūranga katoa, e tuku ana i te whānuitanga o ngā mahi papatahi, whakapae, poutū, me runga. Nā tēnei ka waiho hei taputapu whai hua mō ngā mahi hanga uaua me te hanganga mara e rerekē ana te aronga whakarewa.
He mārama te whānuitanga o te whakamahinga o tēnei Hiko Whakarewa Waro Rino iti-hauwai. E taunakihia ana mō te whakarewa i ngā maitai waro-waenga me ētahi hanganga maitai iti-koranu. Ko ngā rauemi turanga noa ko ngā momo pēnei i te 09Mn2Si, Q345 (he maitai hanganga Hainamana noa e rite ana ki te ASTM A572 Gr. 50), me te 09Mn2V. Nā ōna āhuatanga e pai ai mō te hanga me te mahi whakatika i roto i ngā ahumahi pēnei i te hanga, te hanga kaipuke, te hanga oko pehanga, me ngā mīhini taumaha whānui ina rite te whakarewa, me nui ake rānei i te pakari o te konganuku turanga.
Ko te tauira AWS E7015 / J507 e whakaatu ana i tētahi hua matua i roto i teIrahiko Whakarewa Waro Rinowhakarōpūtanga. Ko tōna paninga hauwai-iti, me te āheinga tūranga-katoa mā te whakamahi i te DCEP, ka aro atu ki ngā wero noa i roto i te whakarewa i ngā maitai ngāwari. Mā te tuku i te konganuku kua whakatakotoria me te pono teitei, ngā āhuatanga miihini pai, me te ngāwari pakaru iti, ka whakaratohia e tēnei hiko he otinga pono mō ngā tohunga e mahi ana i ngā hononga maitai waro me te maitai koranu-iti nui puta noa i ngā rāngai ahumahi rerekē.
