Ngā Tukanga Whakarewa Paipa Rino SSAW mō ngā Raina Hau
Paipa maitai SSAW, e mōhiotia ana ko te paipa whakarewa pewa ruku, e whakamahia whānuitia ana i roto i ngā whakaurunga paipa hau nā tōna pakari me tōna kaha. Heoi, ko te whai huatanga o ēnei paipa e whakawhirinaki nui ana ki te kounga o ngā tikanga whakarewa e whakamahia ana i te wā tāutanga. Ka taea e ngā tikanga whakarewa hē te hua ake he ngoikore me te pakaru o ngā hononga, ka hua ake he tūponotanga haumaru me te rahunga o te pūnaha.

Ko tētahi o ngā mea matua hei whakarite i te pono o te whakaurunga paipa hau mā te whakamahi i te paipa maitai whakarewa porowhita-uru ko te whiriwhiri i te tukanga whakarewa tika. Kei roto i tēnei ko te whakaaro nui ki ngā tikanga whakarewa, ngā rauemi whakakī me te whakarite i mua i te whakarewa. Hei tāpiri, he mea nui te tutuki i ngā paerewa me ngā ture ahumahi hei whakarite i te pono me te haumaru oraina hausngā pūnaha.
He mea nui te whakarite tika mō te whakarewanga i mua i te whakarewanga kia angitu ai te whakarewanga o ngā paipa maitai kua whakarewahia ki te pewa porowhita i roto i ngā whakaurunga raina hau. Kei roto i tēnei ko te horoi me te tirotiro i te mata o te paipa hei tango i ngā poke, i ngā hapa rānei ka pā ki te kounga o te whakarewanga. Hei tāpiri, kia kaha ai, kia pono ai hoki te whakarewanga, me ine tika te paipa me te whakarite.
I te wā e mahi ana i te whakarewanga, he mea nui te aro ki ngā taipitopito me te piri ki ngā tikanga tika. Ko te whiriwhiri i te tikanga whakarewa tika, ahakoa he TIG (whakarewa hau korekore tungsten), he MIG (whakarewa hau korekore whakarewa) he SMAW rānei (whakarewa arc stick) me whiriwhiri i runga i ngā whakaritenga motuhake o te tāutanga paipa hau. Hei tāpiri, ko te whakamahinga o ngā rauemi whakakī kounga teitei me ngā tikanga whakarewa tupato he mea nui ki te whakaputa i ngā whakarewa pono me te pakari e tutuki ai ngā whakaritenga o ngā mahi paipa hau.
Hei tāpiritanga, he mea nui te tirotiro me te whakamātautau i muri i te whakarewa hei whakarite i te kounga me te pono o te whakarewa i roto i ngā whakaurunga paipa hau mā te whakamahi i ngā paipa maitai SSAW. Mā ngā tikanga whakamātautau kore-whakangaro, pērā i te whakamātautau ira-X me te whakamātautau ultrasonic, ka āwhina i te tautuhi i ngā hapa, i ngā koretake rānei o ngā hononga whakarewa kia taea ai te whakatika wawe me te whakarite i te pono o tō pūnaha paipa hau.
Hei whakarāpopototanga, he mea nui ngā tikanga whakarewa tika mō te tāuta i ngā raina hau mā te whakamahi i ngā paipa maitai whakarewa porowhita-uru. Ko te pono me te haumaru o tō pūnaha paipa hau e whakawhirinaki ana ki te kounga o tō whakarewa, nō reira me whai i ngā paerewa me ngā mahi pai o te umanga whakarewa. Mā te whakatairanga i te whakarite tika i mua i te whakarewa, ngā tikanga whakarewa tino tika, me ngā tirotiro tino pai i muri i te whakarewa, ka taea e ngā kaiwhakauru paipa hau te whakarite i te pono me te haumaru o ngā tāutanga paipa maitai SSAW mō ngā tono paipa hau.
