Uea Uea Paa GMAW AWS A5.18 ER70S-G CO2 Mig Uea Welding
Uea Paa GMAW AWS A5.18 ER70S-g CO2 miguwea wiliwili
Nā noi:
Hoʻohana ʻia no ka wiliwili ʻana i nā ʻano ʻāpana kila 500MPa, nā papa mānoanoa a me nā pipeline mānoanoa, no ka wili wikiwiki kiʻekiʻe ma nā metala kumu 500MPa.
Nā hiʻohiʻona:
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.

1. Pono e hoʻoneʻe ʻia ka ʻōpala, ka ʻaila, ka wai a me nā mea haumia ʻē aʻe o ka weld ma mua o ke kuʻi 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.
