AWS E7015-B2L Haʻahaʻa-alloy steels Manual electrode Welding jointing

ʻO AWS E7015-B2L(R307L) ka mea hoʻoheheʻe lima hao hao hao haʻahaʻa, hoʻohana nui ʻia i nā hiʻohiʻona like ʻole. ʻO ka electrode lima i hāʻawiʻia e kā mākou hui he mea kaulana loa ia ma ka mākeke home o Kina ma muli o kona kūlana kiʻekiʻe a me ke kumukūʻai kūpono. He maikaʻi loa kēia ʻano electrode no ka hoʻoheheʻe ʻana i ke kila wela i nā wahi āpau. Hiki i kēia electrode ke weld i nā kila like ʻole a me 13%Mn tempered steel a me Cr steel.

Noi a me ka maʻamau a me ka manaʻo:

ʻO AWS E7015-B2L wela ke kila electrode kūpono no ka hoʻoheheʻe ʻia ʻana o ka paila hoʻomehana ʻana i ka ʻili o ka ʻili a me ka mana mea kanu wai paia, ka mahu paipu a me ka moku kiʻekiʻe e hana ana i ka mahana ma lalo o 550 ℃, e like me 15CrMo paipu pā, A335-P11 paipu, A387Gr.11 pā. A hiki ke hoʻohana no ka 30CrMnSi hoʻoheheʻe ʻia, kūpono no ka manawa o ka haʻahaʻa haʻahaʻa haʻahaʻa. Eia kekahi, pono e hoʻomaʻamaʻa mua i ka weldment ma ke anawaena waena o 160 ℃ ~ 190 ℃ i ka wā wili, a me 690 ± 15 ℃ * 1h mālama wela e like me nā koi maʻamau o nā mea welding.

Nā hiʻohiʻona

ʻO AWS E7015-G2L(R307L) ʻano wela-kūʻai lima electrode he haʻahaʻa sodium hydrogen type lima electrode, paʻa arc, liʻiliʻi splash, hana maikaʻi, desagging maʻalahi, maikaʻi ka hana X-Ray. Loaʻa iā ia nā waiwai mechanical paʻa a hiki ke mālama i ka paʻakikī hopena kiʻekiʻe ma lalo o nā kūlana mālama wela. He hana ʻenehana koʻikoʻi ka preheating no ka wili ʻana i nā māwae anu a hoʻopau i ke koʻikoʻi o ke kila pale wela perlite. I mea e hōʻoia ai i ka maikaʻi o ka welding, ʻaʻohe mea i ke kaʻina o ka wili paʻa paʻa a i ʻole ke kuʻi ʻana, pono e hoʻomaʻamaʻa ʻia a mālama i kahi pae wela. Ma hope o ka pau ʻana o ka hana kuʻi ʻana i ka hoʻoheheʻe ʻana i ka hoʻoluʻu lohi, ʻo ka kuʻi ʻana i ka chromium-molybdenum heat resistant steel pono e hahai pono i ke kumu, ʻoiai i ke kauwela wela pono e hana i kēia, ʻo ka wili nui me ka lole asbestos e uhi i ka weld a ma kahi kokoke i kahi seam, hiki ke hoʻokomo i nā ʻāpana kuʻi liʻiliʻi i loko o ka lole asbestos e hoʻomaha mālie.

ʻO nā kila kalapona kiʻekiʻe Nā mea hoʻoheheʻe electrode manual
