Te hiranga opaipa maitai waro porowhita kua whakapirihiaKāore e taea te wareware i te wā e whiriwhiri ana i te paipa tika mō ngā mahi ahumahi. E mōhiotia ana mō tō rātou kaha me te roa, e whakamahia whānuitia ana ēnei paipa i roto i te kawe hinu me te hau, ngā tipu maimoatanga wai, ngā kaupapa hanga, me ētahi atu. Ka rukuhia e mātou ngā āhuatanga hangarau o te paipa maitai waro porowhita kua whakarewahia, me te arotahi ki tana tukanga whakarewa me ngā whakaritenga.

Te Whakarewa Porowhita: Tirohanga Whānui

Ka hangaia ngā paipa maitai waro kua whakapirihia ki te porowhita mā te tukanga whakapiri porowhita, arā, ko te takai me te whakapiri i ngā rīpene maitai tonu kia rite te āhua. He pai ake tēnei tukanga nā te mea ka whakarite kia ōrite te matotoru puta noa i te paipa. He maha ngā painga o te tikanga whakapiri porowhita, tae atu ki te kaha ake, te ātete nui ake ki te ahotea, me te kaha ki te kawe kawenga. Hei tāpiri, ka taea e ia te whakaputa paipa i ngā rahi rerekē, kia pai ai mō te whānuitanga o ngā mahi.

Hangarau whakarewa ngongo waro:

Te whakarewa paipa warohe wāhanga nui o te tukanga hangahanga nā te mea ka whakarite kia kaha, kia pono hoki te hononga i waenga i ngā ngongo.

- Whakarewa pewa ruku (SAW): Ka whakamahia e tēnei hangarau he hikohiko e hiko tonu ana i roto i te rerenga kirikiri. He tere whakarewa teitei, he pai hoki te uruhanga, he pai mō ngā paipa whānui.

- Te Whakarewa Āwhata Konukura Hau (GMAW/MIG): Ka whakamahia e te GMAW te waea whakarewa me te hau ārai hei whakaputa wera whakarewa. He maha ake ngā whakamahinga, ā, he pai hoki mō ngā paipa rerekē te matotoru.

- Te whakarewa pewa hau tungsten (GTAW/TIG): Ka whakamahia e te GTAW ngā irahiko tungsten kore-e pau me te hau tiaki. Ka whakaratohia he mana whakahaere tika o te tukanga whakarewa, ā, e whakamahia ana mō ngā whakarewa kounga teitei i runga i ngā paipa angiangi.
