No ka mea maʻamaupaipu ailaʻAʻole ʻae ʻia ka wiliwili, paʻakikī ka maikaʻi e hoʻokele a paʻakikī hoʻi e hoʻokō i ka slag welding e koi ʻia i loko, akā naʻe, ʻoi aku ka maikaʻi a me ka hoʻohana nui ʻana i ka welding backing i hana ʻia, manual arc welding method e uhi.Ma keia ala akaka arc, welding hana mea maʻalahi, emi prone pores, slag, incomplete komo a me na weld defects ma hope o, ia manawa, ma muli o ka liʻiliʻi laina kaha, no laila, he wahi wela liʻiliʻi, deformation liʻiliʻi a me ka pohā.
ʻO ke kinoea inert welding abbreviation TIG (Tungsten Inert Gas Weiding) welding.Aia ia ma lalo o ka pale o ke kinoea inert, ʻo ka hoʻohana ʻana i ka tungsten arc i hana ʻia e ka electrode a me ka mea hana kumu hana a me ka uea hoʻoheheʻe hoʻoheheʻe wela (filler wire inā hoʻohana ʻia) he ʻano welding.Hoʻokuʻu ʻia ke kinoea pale pale hoʻomau mai ka nozzle o ka lama, ua hoʻokumu ʻia ke arc a puni ka papa pale i hoʻokaʻawale ʻia mai ke kinoea ea, e pale i kahi hopena maikaʻi loa i ka wela tungsten e pili ana i ka wai weld, e ʻae ai i nā welds kiʻekiʻe.
ʻO nā pono wiliwili TIG:
1) Hiki i ka wili TIG ke weld metala a ʻoi aku ka maikaʻi, hiki ke hoʻokaʻawale maikaʻi ʻia ka wahi wili argon mai ka ea a puni, ʻaʻole ia e hoʻoheheʻe i ka metala, ʻaʻole hoʻi ka metala.TIG kuʻikuʻi kaʻina hana, arc kuʻihao like me 'akomi scavenging ili oxide film.No laila, ʻo ka kūleʻa o nā ʻano hana ʻē aʻe o ka welding maʻalahi oxidized maʻalahi welded, nitriding, chemical reactivity a me nā metala ikaika ʻole ferrous, stainless steel a me nā ʻāpana like ʻole.
2) hopena pale, kiʻekiʻe weld maikaʻi.ʻO Ar kekahi o nā kinoea paʻa a inert ʻaʻole i pane me ka hopena metala, hiki ke hoʻoheheʻe ʻia i loko o ka metala wai ʻaʻole e hoʻohua i nā pores, no laila he hana pale maikaʻi loa ia.ʻO ke kaʻina hana welding he mea hoʻoheheʻe metala maʻalahi a me ke kaʻina hana crystallization, a no laila ke kūlana weld kiʻekiʻe.
3) Ma muli o ka hoʻopili ʻana a me ka hoʻoluʻu ʻana o ke arc ma ke kahe argon, liʻiliʻi ke koʻikoʻi kuʻi a me ka deformation, ʻo ka ʻike wela arc a me ka argon wela kiʻekiʻe, hiki ke hōʻoia i ka komo ʻana o ke aʻa weld, nā ʻāpana liʻiliʻi i hoʻopili ʻia i ka wela, liʻiliʻi welding deformation. a me ka manaʻo māhā.Nui no ka nui welded kila ea quenching tendencies.
4) tungsten arc paʻa, ʻoiai i loko o kahi kuʻekuʻe liʻiliʻi (<10A) aia nō ma lalo o ka hoʻopau paʻa ʻana, ʻoi aku hoʻi no nā mea wiliwili pā lahilahi.
5) hiki ke hoʻomalu ʻia ka wela a me ka uea hoʻopihapiha, a no laila maʻalahi ke hoʻoponopono i ka hoʻokomo wela e hiki ke welded ma nā wahi like ʻole, akā ʻo ke ala kūpono hoʻi e hoʻokō ai i ka wili ʻaoʻao pua.
6) No ka hele ʻole ʻana o ka uea hoʻopiha i ka arc, ʻaʻole ia e hana i ka spatter, weld helehelena.
7) ʻO Ar he kinoea atom hoʻokahi, liʻiliʻi ka wela wela, haʻahaʻa haʻahaʻa haʻahaʻa, wela ka hoʻohana ʻana, ʻoi aku ka maikaʻi o ka puhi ʻana o ke arc, ʻoiai ma nā kūlana haʻahaʻa o kēia manawa a me kahi arc lōʻihi, paʻa mau ke arc, maʻalahi e hana, maʻalahi e hana. e hoʻomalu i ka maikaʻi o ka weld no nā ala paʻakikī e hoʻoheheʻe i ka paipu i ke kūlana a pau.
Maʻalahi ka hana ʻana o TIG welding ma muli o ka maikaʻi, i nā makahiki i hala iho nei, ua lilo ia i ala maʻamau no nā ʻoihana hana mana i ka hoʻonohonoho ʻana a me ka mālama ʻana i nā paipu wela wela i hoʻopaʻa ʻia.Ma lalo o nā kūlana o ka mālama ʻana i ka pūnaewele, a me ka hana ʻana o ke kūlana kuʻi ma nā palena ākea, ʻo ke ʻano hana maʻamau i hoʻohana ʻia ʻo ka hoʻohaʻahaʻa ʻana i ka TIG welding SMAW e uhi i ka maka holoʻokoʻa a i ʻole ka hoʻohana ʻana o TIG welding.
