ʻO ka pūʻali o ka welding arsenals i loaʻa no ka hakakā ʻana i ka hana hoʻoponopono metala ua ulu nui aʻe i nā makahiki, me ka papa inoa alphabetical o ka welder.

ʻO ka pūʻali o ka welding arsenals i loaʻa no ka hakakā ʻana i ka hana hoʻoponopono metala ua ulu nui aʻe i nā makahiki, me ka papa inoa alphabetical o ka welder.
Inā ʻoi aku ʻoe ma mua o 50, ua aʻo paha ʻoe pehea e wili ai me kahi mīkini wiliwili SMAW (Shielded Metal Arc a i ʻole Electrode).
Ua lawe mai nā makahiki 1990 iā mākou i ka ʻoluʻolu o ka MIG (metal inert gas) a i ʻole FCAW (flux-cored arc welding) welding, kahi i hoʻomaha ai nā buzzers he nui.I kēia mau lā, ua komo ka ʻenehana TIG (tungsten inert gas) i nā hale kūʻai mahiʻai ma ke ʻano he ala kūpono e hoʻohui ai i ka metala, alumini a me ke kila kila.
ʻO ka ulu nui ʻana o nā welders multi-purpose i kēia manawa, hiki ke hoʻohana ʻia nā kaʻina hana ʻehā i hoʻokahi pūʻulu.
Ma lalo iho nei nā papa wiliwili pōkole e hoʻomaikaʻi ai i kou mau mākau no nā hopena hilinaʻi, ʻaʻohe o ke kaʻina hana wili āu e hoʻohana ai.
Ua hoʻolaʻa ʻo Jody Collier i kāna ʻoihana i ka hoʻomaʻamaʻa welder a me ka welder.Hoʻopiha ʻia kāna mau pūnaewele Weldingtipsandtricks.com a me Welding-TV.com i nā ʻōlelo aʻoaʻo kūpono a me nā hoʻopunipuni no nā ʻano wiliwili āpau.
ʻO ke kinoea i makemake ʻia no ka wiliwili MIG ʻo ia ke kalapona ʻokikene (CO2).ʻOiai ʻo CO2 ka waiwai a kūpono no ka hana ʻana i nā welds komo hohonu i nā kila mānoanoa, hiki ke wela loa kēia kinoea pale i ka wā e wili ai i nā metala lahilahi.ʻO ia ke kumu i manaʻo ai ʻo Jody Collier e hoʻololi i kahi hui o 75% argon a me 25% carbon dioxide.
"ʻAe, hiki iā ʻoe ke hoʻohana i ka argon maʻemaʻe i ka MIG weld alumini a i ʻole ke kila, akā he mau mea lahilahi wale nō," wahi āna."Hoʻopili maikaʻi ʻia nā mea ʻē aʻe me ka argon maʻemaʻe."
Hoʻomaopopo ʻo Collier he nui nā hui kinoea ma ka mākeke, e like me ka helium-argon-CO2, akā i kekahi manawa paʻakikī lākou e loaʻa a pipiʻi.
Inā hoʻoponopono ʻoe i ke kila kila ma kahi mahiʻai, pono ʻoe e hoʻohui i ʻelua hui ʻana o 100% argon a i ʻole argon a me ka helium no ka wili alumini a me kahi hui ʻana o 90% argon, 7.5% helium a me 2.5% carbon dioxide.
ʻO ka permeability o ka MIG weld e pili ana i ke kinoea pale.Hāʻawi ka carbon dioxide (luna ʻākau) i ka wiliwili komo hohonu e hoʻohālikelike ʻia me argon-CO2 (hema hema).
Ma mua o ka hana ʻana i ka alumini, e hoʻomaʻemaʻe pono i ka weld e pale aku i ka luku ʻana i ka weld.
He mea koʻikoʻi ka hoʻomaʻemaʻe weld no ka mea heheʻe ka alumina ma 3700°F a heheʻe nā metala kumu ma 1200°F.No laila, ʻo kekahi oxide (oxidation a i ʻole keʻokeʻo corrosion) a i ʻole ka aila ma ka ʻili i hoʻoponopono ʻia e pale i ke komo ʻana o ka metala hoʻopiha.
ʻO ka wehe mua ʻana i ka momona.A laila, a laila wale nō, pono e wehe ʻia ka contamination oxidative.Mai hoʻololi i ke kauoha, aʻo aku ʻo Joel Otter o Miller Electric.
Me ka piʻi ʻana o ka kaulana o nā mīkini welding uea i nā makahiki 1990, ua koi ʻia nā mea welder beehive i hoʻāʻo ʻia e hōʻiliʻili i ka lepo ma nā kihi o nā hale kūʻai.
ʻAʻole like me kēlā mau buzzers kahiko i hoʻohana wale ʻia no nā hana hoʻololi o kēia manawa (AC), hana nā welders o kēia manawa ma ke ala ʻokoʻa a me ke au pololei (DC), e hoʻololi ana i ka polarity wili he 120 mau manawa i kekona.
Nui nā pōmaikaʻi i hāʻawi ʻia e kēia hoʻololi polarity wikiwiki, me ka maʻalahi o ka hoʻomaka ʻana, ka liʻiliʻi o ka pipiʻi, ka liʻiliʻi o ka spatter, nā welds ʻoi aku ka maikaʻi, a me ka maʻalahi o ka wili kū pololei a ma luna.
Hoʻohui ʻia me ka ʻoiaʻiʻo o ka hoʻopili ʻana i ka lāʻau e hoʻohua i nā welds hohonu, maikaʻi ia no ka hana o waho (ua puhi ʻia ke kinoea pale ʻo MIG e ka makani), hana maikaʻi me nā mea mānoanoa, a puhi ʻia i ka ʻōpala, lepo, a me ka pena.Hiki ke hoʻohana ʻia nā mīkini welding a maʻalahi hoʻi e hana, no laila hiki iā ʻoe ke ʻike i ke kumu e pono ai ke hoʻopukapuka ʻana i kahi mīkini wiliwili hou a i ʻole multi-processor.
Hāʻawi ʻo Joel Orth o Miller Electric i nā kuhikuhi electrode aʻe.No ka ʻike hou aku e kipa: millerwelds.com/resources/welding-guides/stick-welding-guide/stick-welding-tips.
He pōʻino wiliwili koʻikoʻi ke kinoea hydrogen, e hoʻopaneʻe ana i ka wiliwili ʻana, hāhā ka HAZ i mau hola a i ʻole mau lā ma hope o ka pau ʻana o ka wili, a i ʻole nā ​​mea ʻelua.
Eia naʻe, hiki ke hoʻopau maʻalahi ka hoʻoweliweli hydrogen ma ka hoʻomaʻemaʻe pono ʻana i ka metala.Wehe i ka aila, ka ʻōpala, ka pena a me nā mea maʻamau no ka mea he kumu ia o ka hydrogen.
Eia nō naʻe, he mea hoʻoweliweli ka hydrogen i ka wā e wili ai i ke kila ikaika (e hoʻohana nui ʻia i nā lako mahiʻai hou), nā ʻaoʻao metala mānoanoa, a ma nā wahi hoʻopaʻa paʻa loa.I ka hoʻoponopono ʻana i kēia mau mea, pono e hoʻohana i kahi electrode hydrogen haʻahaʻa a hoʻomaʻamaʻa i ka wahi weld.
Hōʻike ʻo Jody Collier ʻo nā puka spongy a i ʻole nā ​​​​huehu ea liʻiliʻi e ʻike ʻia ana ma ka ʻili o kahi weld he hōʻailona ʻoiaʻiʻo he porosity kāu weld, ʻo ia ka mea i manaʻo ʻia he pilikia helu ʻekahi me ka wili.
Hiki ke loaʻa nā ʻano like ʻole o Weld porosity, me nā pores o ka ʻili, nā wormhole, nā lua, a me nā lua, ʻike ʻia (ma ka ʻili) a ʻike ʻole (hohonu i ka weld).
Ua ʻōlelo pū ʻo Collier, "E hoʻoheheʻe ʻia ka puddle no ka manawa lōʻihi, e ʻae i ke kinoea e paila mai ka weld ma mua o ka maloʻo ʻana."
ʻOiai ʻo 0.035 a me 0.045 iniha ka nui o nā anawaena uea maʻamau, ʻoi aku ka maʻalahi o ke anawaena liʻiliʻi e hana i kahi weld maikaʻi.Manaʻo ʻo Carl Huss o Lincoln Electric i ka hoʻohana ʻana i ka uea 0.025″, ʻoi aku ka nui i ka wā e wili ai i nā mea lahilahi 1/8″ a i ʻole.
Ua wehewehe ʻo ia ʻo ka hapa nui o nā welders e hana i nā welds i ʻoi aku ka nui, hiki ke alakaʻi i ke ahi.Hāʻawi ka uea anawaena liʻiliʻi i ka weld paʻa i ke au haʻahaʻa me ka liʻiliʻi o ke ahi.
E akahele i ka hoʻohana ʻana i kēia ʻano hana ma nā mea mānoanoa (3⁄16″ a ʻoi aku ka mānoanoa), no ka mea, ʻaʻole lawa ka heheʻe ʻana o ka uea 0.025″.
I ka manawa i hiki mai ai ka moeʻuhane no ka poʻe mahiʻai e ʻimi nei i kahi ala maikaʻi aʻe e wili ai i nā metala lahilahi, aluminika a me ke kila kila, ʻoi aku ka maʻamau o nā welders TIG i nā hale kūʻai mahiʻai ma muli o ka ulu nui ʻana o nā mea welders multi-processor.
Eia naʻe, ma muli o ka ʻike pilikino, ʻaʻole maʻalahi ke aʻo ʻana i ka welding TIG e like me ke aʻo ʻana i ka welding MIG.
Pono ʻo TIG i nā lima ʻelua (hoʻokahi e hoʻopaʻa i ke kumu wela i ka electrode tungsten wela o ka lā, ʻo kekahi e hānai i ke koʻokoʻo hoʻopiha i loko o ke arc) a me kahi wāwae (e hana i ka pedal wāwae a i ʻole ka mea hoʻoponopono o kēia manawa i kau ʻia ma ka lama) Hoʻohana ʻia ka hoʻohui ʻana ʻekolu ala e hoʻomaka, hoʻoponopono a hoʻōki i ke kahe o kēia manawa).
No ka pale ʻana i nā hopena e like me kaʻu, hiki i ka poʻe hoʻomaka a me ka poʻe e ʻimi nei e hone i ko lākou mau mākaukau e hiki ke hoʻohana i kēia mau ʻōlelo aʻoaʻo wiliwili TIG, ma ka ʻōlelo a Miller Electric consultant Ron Covell, Welding Tips: The Secret to TIG Welding Success.
