AWS E8015-B2 ʻO nā kila haʻahaʻa haʻahaʻa haʻahaʻa ka pauka metala wiliwili uwea wiliwili mea

He kūpono ʻo AWS E8015-B2 no ka hoʻoheheʻe ʻana i ka paila hoʻoheheʻe ʻana i ka ʻili o ka ʻili a me ka pā wai o ka pā wai e hana ana ma lalo o 550 ℃.ʻO ka paipu mahu, ka moku kiʻekiʻe, e like me 15CrMo tube plate, A335-P11 tube, A387Gr.11 plate;A hiki no hoi ke hoʻohana 'ia i ka hydrogenation reactor, wela exchanger a me na kiʻekiʻe kiʻekiʻe kiʻekiʻe moku a me boiler pipeline kuʻihao, hiki ke hoʻohana 'ia e weld 30CrMnSi hoolei kila.

Hoʻomaʻamaʻa pinepine ʻia ka groove e ka lapalapa ahi a i ʻole ke kaʻina ʻoki plasma.I ka wā e pono ai, pono e hoʻomaʻamaʻa mua ʻia ka ʻokiʻoki, a pono e hana ʻia ka hoʻāʻo PT ma hope o ka wili ʻana e wehe i nā māwae ma ke awāwa.Hoʻohana pinepine ʻia ke ʻano V-like groove, a ʻo ka Angle groove he 60°.Mai ka manaʻo o ka pale ʻana i nā māwae, ʻoi aku ka maikaʻi o ka Angle groove, akā hoʻonui ia i ka nui o ka welding.I ka manawa like, hoʻomaʻemaʻe ʻia ka ʻāʻī a me nā ʻaoʻao ʻelua o loko, a hoʻopau ʻia ka lepo e like me ka aila, ka ʻōpala a me ka wai (dehydrogenation and porosity prevention).
