Optimization a me ka hoʻokele waiwai o ka orbital welding i ka pipeline kūkulu

ʻOiai ʻaʻole ia he mea hou ka ʻenehana hoʻoheheʻe orbital, ke hoʻomau nei ka ulu ʻana, e lilo i ʻoi aku ka ikaika a me ka versatile, ʻoi aku hoʻi no ka wili paipu. He nīnauele me Tom Hammer, he welder akamai ma Axonics ma Middleton, Massachusetts, e hōʻike ana i nā ala he nui e hiki ai ke hoʻohana ʻia kēia ʻenehana no ka hoʻoponopono ʻana i nā pilikia wili paʻakikī. Na Axenics kiʻi
Ua puni ʻo Orbital welding no kahi o 60 mau makahiki, e hoʻohui ana i ka automation i ke kaʻina GMAW. He ala hilinaʻi a kūpono hoʻi no ka hana ʻana i nā welds he nui, ʻoiai ʻaʻole i hoʻohana kekahi mau OEM a me nā mea hana i nā mana o nā welders orbital, e hilinaʻi ana i ka wili lima a i ʻole nā ​​​​mea hoʻolālā paipu metala ʻē aʻe.
Ua puni nā loina o ka welding orbital no nā makahiki he nui, akā ʻo ka hiki o nā welders orbital hou ke lilo i mea hana ikaika loa i ka pahu hana welder, ʻoiai he nui o lākou i kēia manawa he mau hiʻohiʻona "akamai" e maʻalahi ai ka hoʻonohonoho ʻana a me ka lawelawe ʻana ma mua o ka wili maoli. . ● E hoʻomaka me nā hoʻonohonoho wikiwiki a pololei e hōʻoia i nā welds paʻa, maʻemaʻe a hilinaʻi.
ʻO ka Axenics Welding Team ma Middleton, Massachusetts, kahi mea hana ʻāpana ʻaelike, kōkua i ka nui o kāna mau mea kūʻai aku i ka welded orbital inā loaʻa ka mea kūpono no ka hana.
"Ma nā wahi a pau e hiki ai, makemake mākou e hoʻopau i ke kumu o ke kanaka i ka wiliwili, no ka mea, hana pinepine nā mea welder orbital i nā welds ʻoi aku ka maikaʻi," wahi a Tom Hammer, ka welder kūpono ma Axenics.
ʻOiai ua hana ʻia ka welding mua loa ma 2000 mau makahiki i hala aku nei, ʻo ka welding hou he kaʻina hana kiʻekiʻe loa i mea nui o nā ʻenehana a me nā kaʻina hana hou. No ka laʻana, hiki ke hoʻohana ʻia ka welding orbital e hana i nā ʻōnaehana paipu maʻemaʻe kiʻekiʻe i hoʻohana ʻia no ka hana ʻana i nā wafers semiconductor, i hoʻohana ʻia i nā mea uila āpau i kēia mau lā.
ʻO kekahi o nā mea kūʻai aku o Axenics he ʻāpana o kēia kaulahao lako. Ke ʻimi nei ka hui i kahi mea hana ʻaelike e kōkua i ka hoʻonui ʻana i kona hiki ke hana, ʻo ia hoʻi no ka hana ʻana a me ka hoʻokomo ʻana i nā ala kila kuhili maʻemaʻe e hiki ai i nā kinoea ke kahe ma ke kaʻina hana pā.
ʻOiai e loaʻa ana nā mea welder orbital a me nā turntables paʻi lama no ka hapa nui o ka hana paipu ma Axenics, ʻaʻole lākou e pale i ka wili lima i kēlā me kēia manawa.
Ua nānā ʻo Hammer a me ka hui welding i nā koi o ka mea kūʻai aku a nīnau i nā nīnau a me ka manawa:
Hoʻohana ʻo Hammer i ka Swagelok M200 a me Arc Machines Model 207A e hoʻohuli ana i nā welder orbital i hoʻopili ʻia. Hiki iā lākou ke paʻa i nā paipu mai 1/16 ″ a i 4 ″.
"ʻAe ʻo Microheads iā mākou e komo i nā wahi paʻakikī loa," wahi āna. "ʻO kekahi o nā palena o ka welding orbital inā he poʻo kūpono ko mākou no kahi hui. Akā i kēia lā, hiki iā ʻoe ke ʻōwili i ke kaulahao a puni ka paipu āu e wili ai. Hiki i nā welders ke hele i ke kaulahao a ʻaʻohe palena i ka nui o nā welds hiki iā ʻoe ke hana. Ua ʻike au i kekahi mau mīkini wili i nā paipu 20″. He mea kupanaha ka hana a keia mau mīkini i keia la.
Ke noʻonoʻo nei i nā koi maʻemaʻe, ka nui o nā welds e pono ai a me ka mānoanoa o ka pā haʻahaʻa, ʻo ka welding orbital kahi koho kūpono no kēia ʻano papahana. I ka hana ʻana me ka paipu hoʻokele airflow, wili pinepine ʻo Hammer i ke kila kila 316L.
“A laila, lahilahi nā mea. Ke kamaʻilio nei mākou e pili ana i ka wiliwili metala lahilahi. Me ka wili lima, hiki i ka hoʻololi liʻiliʻi ke hana i ka weld e haki. ʻO ia ke kumu makemake mākou e hoʻohana i nā poʻo welding orbital, kahi e hiki ai iā mākou ke wili i kēlā me kēia ʻāpana o ka paipu weld a hoʻomaʻamaʻa pono, ma mua o ka hoʻokomo ʻana i ka ʻāpana. e hemolele ia. Ma ka lima, hana ʻia ka hoʻololi ʻana e ka maka, a inā mākou e hele wāwae nui, hiki ke hele pololei i ka mea.
ʻO ka hana he mau haneli o nā welds pono e like. Hoʻopau ka welder orbital i hoʻohana ʻia no kēia hana i ka weld i ʻekolu mau minuke; i ka wā e holo ana ka Hammer i ka wikiwiki loa, hiki iā ia ke wili lima i ka paipu kila kila ma kahi o hoʻokahi minuke.
“Akā naʻe, ʻaʻole lohi ke kaʻa. Holo mua ʻoe iā ia ma ka wikiwiki kiʻekiʻe i ke kakahiaka a i ka hopena o ka lā e holo mau ana ia ma ka wikiwiki kiʻekiʻe, "wahi a Hammer. "E holo mua au i ka wikiwiki loa i ke kakahiaka, akā i ka hopena, ʻaʻole."
He mea koʻikoʻi ka pale ʻana i nā mea ʻino mai ke komo ʻana i nā paipu kila kila, ʻo ia ke kumu e hana pinepine ʻia ai ka hoʻoheheʻe ʻana i ka maʻemaʻe kiʻekiʻe i ka ʻoihana semiconductor i loko o kahi lumi maʻemaʻe.
Hoʻohana ʻo Hammer i ka tungsten i hoʻopaʻa mua ʻia i kāna mau kukui e like me ka Orbiter. ʻOiai ke hāʻawi nei ka argon maʻemaʻe i ka hoʻomaʻemaʻe waho a me loko no ka wili lima a me ka orbital, e pōmaikaʻi hoʻi ka wili orbital mai ka hana ʻana i kahi wahi paʻa. Ke hoʻokuʻu ʻia ka tungsten, hoʻopiha ka sheath i ke kinoea a pale i ka weld mai ka oxidation. I ka hoʻohana ʻana i ka lama lima, hāʻawi ʻia ke kinoea i hoʻokahi ʻaoʻao o ka paipu e wili ʻia.
ʻOi aku ka maʻemaʻe o nā welds orbital no ka mea ʻoi aku ka lōʻihi o ka uhi ʻana o ke kinoea i ka paipu. I ka hoʻomaka ʻana o ka welding, hāʻawi ka argon i ka pale a hiki i ka mea welder e māʻona i ke anuanu o ka weld.
Hana pū ʻo Axenics me kekahi mau mea kūʻai ikehu ʻē aʻe e hana ana i nā wahie hydrogen no nā kaʻa like ʻole. No ka laʻana, hoʻohana kekahi mau forklift i loko o nā pūnaeau wahie hydrogen e pale ai i nā huahana kemika mai ka luku ʻana i nā lako meaʻai. ʻO ka wai wale nō ka hopena o kahi pūnaeau wahie hydrogen.
Loaʻa i kekahi o nā mea kūʻai aku nā koi like me ka mea hana semiconductor, e like me ka hoʻomaʻemaʻe weld a me ke kūlike. Makemake ʻo ia e hoʻohana i ke kila kuhili ʻole 321 no ka wiliwili paia lahilahi. Eia nō naʻe, pili ka hana i ke kūkulu ʻana i kahi prototype manifold me nā pahu valve he nui, e puka ana kēlā me kēia ma kahi ʻaoʻao ʻē aʻe, e waiho ana i kahi lumi liʻiliʻi no ka wili.
He $2,000 ke kumu kūʻai o ka welder orbital kūpono no kēia hana a e hoʻohana ʻia no ka hana ʻana i nā ʻāpana liʻiliʻi, me ke kumu kūʻai he $250. ʻAʻohe manaʻo kālā. Eia nō naʻe, loaʻa iā Hammer kahi hoʻonā e hoʻohui i ka wili lima a me ka orbital.
"I kēia hihia, e hoʻohana wau i ka turntable," wahi a Hammer. “Ua like maoli nō ia me ka welding orbital, akā hoʻohuli ʻoe i ka paipu, ʻaʻole ka electrode tungsten a puni ka paipu. Hoʻohana au i koʻu lama lima, akā hiki iaʻu ke hoʻopaʻa iā ia i loko o ka vise ma ke kūlana kūpono e mālama i koʻu mau lima… manuahi, no laila ʻaʻole hiki i nā lima kanaka ke hōʻino i ka weld ma muli o ka haʻalulu a haʻalulu paha. Hoʻopau kēia i ka hapa nui o ke kumu hewa kanaka. ʻAʻole ia maikaʻi loa, e like me ka orbital welding no ka mea ʻaʻole ia i loko o ka hale, akā hiki ke hana ʻia kēia ʻano wili i loko o kahi lumi maʻemaʻe e hoʻopau i nā mea haumia.
ʻOiai ʻo ka ʻenehana welding orbital e hōʻoia i ka maʻemaʻe a me ka hana hou ʻana, ʻike ʻo Hammer a me kāna mau hoa welder he mea koʻikoʻi ke kūpaʻa weld i ka pale ʻana i ka downtime ma muli o nā hemahema wili. Hoʻohana ka hui i ka hoʻāʻo non-destructive testing (ND) a i kekahi manawa hoʻāʻo luku no nā welds orbital āpau.
"Ua hōʻoia ʻia kēlā me kēia weld a mākou e hana ai," wahi a Hammer. "Ma hope o kēlā, nānā ʻia nā welds me kahi spectrometer helium. Ma muli o ka kikoʻī a i ʻole nā ​​​​koi o ka mea kūʻai aku, nānā ʻia kekahi mau welds e ka radiograph. Hiki nō hoʻi ke hoʻāʻo ʻino.
Hiki i ka hoʻāʻo ʻino ke komo i nā hoʻāʻo ikaika tensile e hoʻoholo ai i ka ikaika tensile hope loa o ka weld. No ke ana ʻana i ke koʻikoʻi nui e hiki ai i kahi weld ma kahi mea e like me 316L stainless steel ke kūpaʻa ma mua o ka hāʻule ʻana, hoʻolōʻihi ka hoʻāʻo a hoʻolōʻihi i ka metala a hiki i ka haki.
Alternative ikehu consumer welds i kekahi manawa ma lalo o kani ultrasonic non-destructive ho'āʻo ma luna o ka welds o triple wela exchanger hydrogen wahie keena pauku i hoʻohana 'ia i loko o 'ē aʻe ikehu machines a me nā kaʻa.
“He hoʻāʻo koʻikoʻi kēia no ka mea ʻo ka hapa nui o nā mea a mākou e hoʻouna ai i loko o nā kinoea weliweli. He mea koʻikoʻi ia iā mākou a me kā mākou mea kūʻai aku he kīnā ʻole ke kila kila a ʻaʻole e kahe, "wahi a Hammer.
