He aha ka Submerged Arc Welding (SAW)?

ʻO ka hoʻoheheʻe ʻana i ka arc submerged (SAW), e like me ka inoa e hōʻike nei, hana ʻia ma lalo o kahi papa pale a i ʻole kahi uhi o ka flux. Ma muli o ka uhi mau ʻia ʻana o ka arc e ka mānoanoa o ka flux, hoʻopau ia i kekahi radiation mai nā arches i hōʻike ʻia a me ka pono o nā pale hoʻoheheʻe. Me ʻelua mau ʻano o ke kaʻina hana, ʻo ka ʻakomi a me ka semi-akomi, ʻo ia kekahi o nā kaʻina hana hoʻoheheʻe i hoʻohana nui ʻia i ka ʻoihana hana. ʻO Wenzhou Tianyu Electronic Co., Ltd., kekahi o nā mea hoʻolako uea hoʻoheheʻe arc submerged kaulana ma Kina, e hōʻike ana i ke kumumanaʻo a me nā hoʻohana ʻana o ka hoʻoheheʻe submerged. E ʻike kākou iā lākou i ko lākou ʻano:

Kaʻina Hana:

E like me ka wili MIG, hoʻohana pū ʻo SAW i ke ʻano hana o ka hoʻokumu ʻana i kahi arc ma waena o ka hui wili a me ka uea electrode ʻōlohelohe mau. Hoʻohana ʻia kahi papa lahilahi o ka flux a me ka slag e hana i nā hui kinoea pale a e hoʻohui i nā mea hoʻohuihui e pono ai i ka waihona wili. I ka hoʻomau ʻana o ka wili, hoʻokuʻu ʻia ka uea electrode ma ka nui like o ka hoʻohana ʻana a ua omo ʻia ka flux keu ma o kahi ʻōnaehana vacuum no ka hana hou ʻana. Ma waho aʻe o ka pale ʻana i ka radiation, he mea maikaʻi loa nā papa flux i ka pale ʻana i ka nalowale o ka wela. ʻO ka pono wela maikaʻi loa o kēia kaʻina hana, ma kahi o 60%, ua hāʻawi ʻia i kēia mau papa flux. Eia kekahi, ʻaʻohe loa ka hana SAW i ka pīpī ʻana a ʻaʻole pono kekahi kaʻina hana hoʻohemo fume.

Ke kaʻina hana:

E like me nā kaʻina hana kuʻihao ʻē aʻe, ʻo ke ʻano o nā hui kuʻihao e pili ana i ka hohonu o ke komo ʻana, ke ʻano a me ka hoʻohuihui kemika o ka metala kuʻihao i waiho ʻia e hoʻomalu pinepine ʻia e nā palena kuʻihao e like me ke au, ka uila arc, ka wikiwiki o ka hānai ʻana o ka uea kuʻihao, a me ka wikiwiki o ka huakaʻi kuʻihao. ʻO kekahi o nā hemahema (ʻoiaʻiʻo, loaʻa nā ʻano hana e kūʻē iā lākou) ʻo ia ka hiki ʻole i ka mea kuʻihao ke nānā aku i ka waihona kuʻihao a no laila ke hilinaʻi nui nei ke ʻano o ka luawai i nā palena hana.

Nā palena hana:

E like me ka mea i ʻōlelo ʻia ma mua, aia wale nō ia me nā palena hana, a hoʻomaikaʻi ka mea wili i ka hui wili. No ka laʻana, i loko o kahi hana hana aunoa, ʻo ka nui o ka uea a me ke kahe i hoʻohana ʻia e kūpono i ke ʻano maʻamau, ka mānoanoa o ka mea, a me ka nui o ka hana he kuleana koʻikoʻi ia i ka hoʻoholo ʻana i ka helu hoʻokahe a me nā ʻano bead.

Uea:

Ma muli o ke koi o ka nui o ka waiho ʻana a me ka wikiwiki o ka huakaʻi, hiki ke koho ʻia nā uwea ma hope

·Uaea pālua

·Nui nā uea

· Uea ʻōwili

· Hoʻohui ʻia ka pauka metala

· Uea hoʻokahi me ka hoʻohui wela

· Uea hoʻokahi me ka hoʻohui anu

Kahe:

Hoʻohana nui ʻia ka hui ʻana o nā oxides o kekahi mau mea e like me ka manganese, titanium, calcium, magnesium, silicon, alumini, a me ka calcium fluoride ma ke ʻano he flux i loko o SAW. ʻO ka maʻamau, ua koho ʻia ka hui ʻana i mea e hāʻawi ai i nā waiwai mechanical i manaʻo ʻia ke hui pū ʻia me ka uea wili. Pono hoʻi e hoʻomaopopo ʻia he kuleana koʻikoʻi ka haku mele ʻana o kēia mau fluxes i ka voltage arc hana a me nā palena o kēia manawa. Ma muli o ke koi wili, ʻelua mau ʻano fluxes, bonded a me fused i hoʻohana ʻia i ke kaʻina hana.

Nā Hoʻohana:

Loaʻa i kēlā me kēia ʻano hana kuʻihao kāna mau hana ponoʻī, kahi e hoʻopili pinepine ʻia ma muli o ka nui o ka hoʻokele waiwai a me ke koi ʻana i ka maikaʻi.

ʻOiai hiki ke hoʻohana maikaʻi ʻia ʻo SAW no nā hui butt (longitudinal a me circumferential) a me nā hui fillet, he kakaikahi nā kapu liʻiliʻi. Ma muli o ke kahe o ka waihona weld, ka slag i ke ʻano heheʻe a me kahi papa palupalu o ka flux, lawe mau ʻia nā hui butt ma ke kūlana pālahalaha, a ma ka ʻaoʻao ʻē aʻe, hana ʻia nā hui fillet ma nā kūlana āpau - pālahalaha, horizontal, a me vertical.

Pono e hoʻomaopopo ʻia inā e hoʻokō ʻia nā kaʻina hana kūpono a me ke koho ʻana o nā palena no nā hoʻomākaukau hui, hiki ke hoʻokō pono ʻia ʻo SAW no nā mea o kekahi mānoanoa.

Hiki ke hoʻohana pono ʻia no nā kila kalapona, nā kila kila kila a me nā kila alloy haʻahaʻa a me kekahi mau mea alloys a me nā mea hana non-ferrous, inā hoʻohana ʻia nā hui pū ʻana o ka uea a me ka flux i manaʻo ʻia e ke code ASME.

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

Me ka hoʻohana nui ʻana o ka uea electrode a me nā hiki ke hana automation, ʻo SAW kekahi o nā kaʻina hana kuʻihao i ʻimi nui ʻia ma ka ʻoihana hana.
