Whakamōhio mai:
I roto i te rāngai ahumahi e whanake tonu ana, he mea nui te whanaketanga o te hangarau whakarewa ki te whakapiki i te hua, te whai huatanga me te tika whānui. I te mea kei te piki haere tonu te hiahia mō ngā tikanga whakarewa pono, pakari hoki, kua huri ngā hangarau auaha pēnei i te Spiral Submerged Arc Welding (HSAW). He mea whakamiharo te HSAW e whakakotahi ana i ngā painga o te pewa ruku me te whakarewa porowhita, ā, kei te huri haere i te ao whakarewa. I roto i tēnei tuhinga, ka tūhuratia e mātou te ao whakamīharo o te whakarewa pewa ruku porowhita me tōna hiranga ki te whakapai ake i te whai huatanga me te tika o ngā tukanga whakarewa ahumahi.
He aha te Whakarewa Āwhata Porowhita (HSAW)?
Ko te whakarewa porowhita-uru (HSAW), e mōhiotia ana ko te whakarewa porowhita, he tikanga whakarewa motuhake e āwhina ana ki te hono i ngā paipa rino roa, tonu. Ko te tikanga ko te whāngai i te paipa rino ki roto i tētahi mīhini, ka tukuna tonutia he pewa hiko e te pane whakarewa porowhita hurihuri, ka hanga he whakarewa maeneene, he rite tonu. Ka neke porowhita te pane whakarewa i te taha o roto, o waho rānei o te paipa hei whakarite i te ōritetanga me te pumau o te tukanga whakarewa.
Whakapai ake i te whai huatanga:
He maha ngā painga o te HSAW ki te tukanga whakarewa, ā, ka piki ake te pai o te mahi. Ko tētahi o ngā painga nui o te HSAW ko tōna kaha ki te whakarewa i ngā paipa o te nuinga o te rahi me te matotoru. Mā tēnei whānuitanga ka taea te whakarite me te urutau, ka taea ai e ngā ahumahi te whakatutuki i ngā whakaritenga kaupapa rerekē. Mā te haere tonu o te whakarewa ka kore e hiahiatia he whakamutu me te tīmatanga pinepine, ka whakaitihia te wā kore mahi me te whakapiki i te hua. Hei tāpiri, mā te āhua aunoa o te tukanga ka whakaitihia te whakawhirinaki ki te mahi ā-ringa, ka whakaitihia te puta o ngā hapa, ā, ka whakapiki ake i te putanga katoa.
Te tika o te arotautanga:
Ko te tika te tohu o ia tukanga whakarewa angitu, ā, he tino pai te HSAW i tēnei āhuatanga. Mā te nekehanga porowhita o te pane whakarewa ka whakarite kia ōrite te āhua whakarewa puta noa i te porowhita katoa o te paipa. Mā tēnei ōritetanga ka whakakorea te tūponotanga o ngā ngoikoretanga, ngā hapa rānei i roto i te whakarewa, ka whakarite i te hanganga me te pono. Hei tāpiri, ka taea e ngā pūnaha whakahaere matatau i roto i ngā mīhini HSAW te whakarite tika i ngā tawhā whakarewa pērā i te ngaohiko pewa me te tere whāngai waea, ka hua ake he whakarewa tika me te taea te whakahoki. Mā tēnei tika ka whakapai ake i te kounga whānui o te hononga whakarewa, ā, ka whakaitihia te tūponotanga o ngā hapa, ngā rahunga rānei.
Ngā tono a te HSAW:
Nā ngā painga kore e taea te whakataurite o te HSAW, he mea rongonui tēnei hangarau whakarewa i roto i ngā ahumahi maha. He whānuitia te whakamahinga o te HSAW i roto i te hanganga paipa i roto i te rāngai hinu me te hau. Mā ngā whakarewa pono e whakaratohia ana e te HSAW ka whakarite i te pono me te pakari o ēnei paipa, he mea nui mō te kawe pai o te hinu me te hau i ngā tawhiti roa. Hei tāpiri, he tono kei roto i te umanga hangahanga te HSAW, e whakamahia ana hei hanga i ngā wāhanga hanganga rino nui pērā i ngā pou me ngā kurupae. Nā te pai me te tika o te HSAW, he mea pai mō ēnei kaupapa uaua, ka whakaiti i te wā hanga me te whakarite i te pumau o te hanganga.
Hei whakamutunga:
Hei whakarāpopototanga, ko te whakarewa āwhata porowhita (HSAW) he hangarau whakarewa hou kua huri i ngā tukanga whakarewa ahumahi. Nā te kaha ki te whakapiki i te pai me te tika, kua noho te HSAW hei taonga nui ki ngā ahumahi mai i te hinu me te hau ki te hanga. Nā te āhua tonu me te aunoa o te tukanga, me tana pūnaha whakahaere tika, ka hua ake he whakarewa whai hua me te pono. I te whanaketanga haere tonu o te hangarau, tera pea ka nui haere te mahi a te HSAW ki te whakatutuki i ngā hiahia o te rāngai ahumahi hou, me te whakarite kia kaha ngā hononga whakarewa.
