He aha ka Submerged Arc Welding (SAW)?

ʻO ka hoʻoheheʻe ʻia ʻana o ke arc submerged (SAW), e like me ka ʻōlelo ʻana o ka inoa, e hana ʻia ma lalo o kahi papa pale a i ʻole ka uhi o ka flux.E like me ka uhi mau ʻana o ke arc e ka mānoanoa o ka flux, hoʻopau ia i nā pāhawewe mai nā ʻaʻa i ʻike ʻia a me ka pono o nā pale kuʻi.Me nāʻanoʻokoʻaʻelua o ke kaʻina hana, 'akomi a me ka semi-aunoa,ʻo ia kekahi o ka hoʻohana nuiʻana i ke kaʻina hana i hoʻohanaʻia i kaʻoihana hana.ʻO Wenzhou Tianyu Electronic Co., Ltd., kekahi o nā mea hoʻolako wili wili arc submerged kaulana i Kina, e hōʻike ana i ke kumu a me ka hoʻohana ʻana i ka wili sub-arc.E ʻike kākou i ke ʻano o lākou:

Kaʻina hana:

E like me ka MIG welding, hoʻohana pū ʻo SAW i ke ʻano o ka hoʻokumu ʻana i kahi arc ma waena o ka hui weld a me ka uea electrode hoʻomau.Hoʻohana ʻia kahi ʻāpana lahilahi o ka flux a me ka slag no ka hoʻoulu ʻana i nā hui kinoea pale a hoʻohui i nā alloys pono i ka wai weld, kēlā me kēia.Ke hoʻomaka nei ka weld, hoʻokuʻu ʻia ka uea electrode ma ka helu like o ka hoʻohana ʻana a hoʻomoʻi ʻia ka flux keu ma o kahi ʻōnaehana hoʻoheheʻe no ka hana hou ʻana.Ma waho aʻe o ka pale ʻana i ka radiation, ʻoi aku ka maikaʻi o nā papa flux i ka pale ʻana i ka wela.ʻO ka maikaʻi wela maikaʻi o kēia kaʻina hana, ma kahi o 60%, pili i kēia mau papa flux.ʻAʻole loaʻa ke kaʻina hana ʻo SAW i ka spattering a ʻaʻole koi i kahi kaʻina hoʻoheheʻe fume.

Kaʻina hana:

E like me nā kaʻina hana weld ʻē aʻe, ʻo ka maikaʻi o nā hui weld e pili ana i ka hohonu o ke komo ʻana, ke ʻano a me ke ʻano kemika o ka weld metala i waiho ʻia e kaohi mau ʻia e nā ʻāpana weld e like me ke au, ka uila arc, ka weld wire feed rate, a me ka wikiwiki huakaʻi weld.ʻO kekahi o nā drawbacks (ʻoiaʻiʻo, loaʻa nā ala e kūʻē iā lākou) ʻaʻole hiki i ka welder ke nānā i ka wai weld a no laila ke hilinaʻi nei ka maikaʻi o ka pūnāwai i nā ʻāpana hana.

Nā ʻāpana hana:

E like me ka mea i ʻōlelo ʻia ma mua, aia wale nō me nā ʻāpana kaʻina, a hoʻomaʻamaʻa kahi welder i ka hui weld.No ka laʻana, i ke kaʻina hana maʻalahi, ʻo ka nui o ka uea a me ka flux i hoʻohana ʻia i kūpono no ke ʻano maʻamau, ka mānoanoa o nā mea, a me ka nui o ka hana he mea koʻikoʻi i ka hoʻoholo ʻana i ka helu deposition a me nā ʻano bead.

Uea:

Ma muli o ke koi o ka helu deposition a me ka wikiwiki o ka huakaʻi ma hope o nā uea hiki ke koho ʻia

·Uea māhoe

· Nui nā uea

· uwea tubular

· Hoʻohui pauda metala

· Hoʻokahi uea me ka hoʻohui wela

· Hoʻokahi uea me ka hoʻohui anu

ʻAi:

ʻO ka hui pū ʻana o nā oxides o kekahi mau mea e like me ka manganese, titanium, calcium, magnesium, silicon, aluminika, a me ka calcium fluoride e hoʻohana nui ʻia e like me ka flux i SAW.ʻO ka maʻamau, koho ʻia ka hui ʻana e like me ka hāʻawi ʻana i nā waiwai mechanical i manaʻo ʻia i ka wā e hui pū ai me ka uwea welding.Pono e hoʻomaopopo ʻia he mea koʻikoʻi ke ʻano o kēia mau fluxes i ka volta arc hana a me nā ʻāpana o kēia manawa.Ma muli o ke koi welding, ʻelua mau ʻano o nā fluxes, hoʻopaʻa ʻia a fused i hoʻohana ʻia i ke kaʻina hana.

Hoʻohana:

Loaʻa i kēlā me kēia ʻano hana welding kāna mau hoʻonohonoho ponoʻī, kahi maʻamau e uhi ʻia ma muli o ka nui o ka hoʻokele waiwai a me ka pono o ka maikaʻi.

ʻOiai hiki ke hoʻohana maikaʻi ʻia ʻo SAW no nā hui kīʻaha ʻelua (longitudinal a circumferential) a me nā hui fillet, he liʻiliʻi nā palena liʻiliʻi.Ma muli o ka wai o ka wai weld, slag i loko o ke ʻano hoʻoheheʻe a me kahi ʻāpana o ka flux, e hoʻokō mau ʻia nā hui kī ma ke kūlana pālahalaha, a ma kekahi ʻaoʻao, ua hana ʻia nā hui fillet ma nā kūlana āpau - pālahalaha, ākea, a kū pololei.

Pono e hoʻomaopopo ʻia i ka wā e hoʻokō ʻia ai nā kaʻina hana kūpono a me ke koho ʻana i nā ʻāpana no ka hoʻomākaukau ʻana, hiki ke hoʻokō pono ʻia ʻo SAW no nā mea o kēlā me kēia mānoanoa.

Hiki ke hoʻohana maikaʻi ʻia no nā kila kalapona, nā kila kila a me nā kila haʻahaʻa haʻahaʻa a me ka liʻiliʻi o nā mea hao non-ferrous a me nā mea waiwai, hāʻawi ʻia ka ASME code i manaʻo ʻia e hoʻohana ʻia nā hui ʻana o ka uea a me ka flux.

Loaʻa iā SAW kahi wahi paʻa i nā ʻoihana mīkini kaumaha a me nā ʻoihana hana moku no nā ʻāpana wili nui, nā paipu anawaena nui, a me nā moku hana.

Me ka hoʻohana kiʻekiʻe loa o ka uea electrode a me ka hiki ke loaʻa i ka automation, ʻo SAW kekahi o nā mea i ʻimi nui ʻia ma hope o ke kaʻina hana wili i ka ʻoihana hana.
