Uea Paa GMAW AWS ER70S-6 CO2 miguwea wiliwili
NĀ PALAPALA:
Hoʻohana ʻia no ka wiliwili 500MPa haʻahaʻa haʻahaʻa haʻahaʻa hoʻokahi a me multi-pass kuʻi;no hoi no ke kiʻekiʻe māmā lahilahi papa, paipu laina kila kuʻihao.
He kūpono no ka wili lima, ka wili a me ka wili robot, e like me ka mīkini ʻaila, nā mīkini crane kaumaha, nā moku kaomi,
nā moku ʻaila-kemika, kino moku, , kūkulu kila, etc.
NA ANOAI:
ʻO kēia uea GMAW no Rm 500MPa ke kila kalapona me ka pale kinoea o CO2 a i ʻole M21.
Liʻiliʻi spatter, nani hiʻona, kiʻekiʻe deposition pono a me ka weld metala porosity sensibility uuku.Ua kūpono nā kūlana a pau.
NĀ MEA:
1. Pono e hoʻoneʻe ʻia ka ʻōpala, ka ʻaila, ka wai a me nā mea haumia ʻē aʻe o ka weld ma mua o ka hoʻopili ʻana.
2. E ho'oholo 'ia nā waiwai mehameha o nā metala weld a pau ma ka ho'okomo wela, 'oi aku ka maika'i o ka ho'okomo wela li'ili'i ma mua o ka mea nui.
