1. Welded huinahalike paipu mea he hakahaka huinahalike kila huinahalike paipu, no hoi i ikeia he puha anu-hana kila.Hoʻokumu ʻia ia e ke kuʻi anu a me ke kuʻekuʻe kiʻekiʻe ma hope o ka ʻōwili wela a i ʻole ka ʻōwili ʻia a i ʻole ka coil e like me ke kila Pāhaʻi ʻia me ke ʻano ʻāpana kea a me ka nui.
Ma waho aʻe o ka mānoanoa o ka pā mānoanoa o ka pā mānoanoa pāhaʻi paipu, ka nui kihi a me ka lihi flatness hiki a oi aku paha i ka pae o ke kū'ē welded anu-hana huinaha paipu.Aia ka nui o ka huina R ma waena o 2 manawa a 3 manawa o ka mānoanoa o ka pā..E like me ka makemake o nā mea kūʻai, hiki iā mākou ke hana i nā paipu huinahā R-angle o ka nui i makemake ʻia e nā mea kūʻai;
