TIG
1.Palapala noi :
TIG wiliwili(tungsten argon arc welding) ʻo ia ke ʻano kuʻikuʻi e hoʻohana ʻia ai ka Ar maʻemaʻe ma ke ʻano he kinoea pale a hoʻohana ʻia nā electrodes tungsten e like me nā electrodes.Hāʻawi ʻia ka uea kuʻi TIG i nā ʻāpana pololei o kekahi lōʻihi (maʻa mau lm).Inert kinoea shielded arc welding me ka hoʻohana ʻana i ka tungsten maʻemaʻe a i ʻole ka tungsten hoʻāla ʻia (tungsten thoriated, cerium tungsten, zirconium tungsten, lanthanum tungsten) ma ke ʻano he electrode non-melting, me ka hoʻohana ʻana i ke arc ma waena o ka electrode tungsten a me ka mea hana e hoʻoheheʻe i ka metala e hana i kahi weld.ʻAʻole hoʻoheheʻe ʻia ka electrode tungsten i ka wā o ke kaʻina hana kuʻi ʻana a hana wale ia ma ke ʻano he electrode.I ka manawa like, hānai ʻia ka argon a i ʻole helium i loko o ka nozzle o ka lama no ka pale.Hiki ke hoʻohui ʻia nā metala hou e like me ka makemake.Ua ʻike ʻia ma ka honuaTIG wiliwili.
2. Pōmaikaʻi：
ʻO ka pōmaikaʻi nui o ke ʻano welding TIG hiki iā ia ke weld i kahi ākea o nā mea.Me nā mea hana me ka mānoanoa o 0.6mm a ma luna, ʻo nā mea i loaʻa i ke kila kila, aluminika, magnesium, keleawe a me kāna mau ʻāpana, hao hina hina, nā keleawe like ʻole, nickel, kālā, Titanium a me ke kēpau.ʻO ke kahua nui o ka noi ʻana ʻo ka wili ʻana o nā mea hana lahilahi a me ka mānoanoa ma ke ʻano he aʻa e hele ai i nā ʻāpana mānoanoa.
3. Nānā:
A. Shielding kinoea holo koi: i ka wā o ka kuʻihao o keia manawa ma waena o 100-200A, he 7-12L / min;i ka wā o ke kuʻi ʻana ma waena o 200-300A, ʻo ia ka 12-15L / min.
B. ʻO ka lōʻihi o ka tungsten electrode e like me ka pōkole e pili ana i ka nozzle, a ʻo ka lōʻihi o ke arc e hoʻomalu mau ʻia ma 1-4mm (2-4mm no ke kuʻi ʻana i ke kila kalapona; 1-3mm no ke kuʻi ʻana i ke kila haʻahaʻa. a me ke kila kila).
C. Ke ʻoi aku ka wikiwiki o ka makani ma mua o 1.0m/s, pono e lawe ʻia nā hana pale makani;e hoʻolohe i ka ea e pale aku i ka pōʻino i ka mea hana.
D. E wehe pono i ka aila, ka ʻōpala a me ka lepo lepo mai ka wahi wili i ka wā wili.
E. Manaʻo ʻia e hoʻohana i ka mana DC me nā hiʻohiʻona o waho, a ʻoi aku ka maikaʻi o ka pou tungsten.
F. I ka wā e wiliwili ai i ke kila kila haʻahaʻa ma luna o 1.25%Cr, pono e pale ʻia ka ʻaoʻao hope.
MIG
1. Noi:
MIG wiliwiliʻo ia ka hoʻoheheʻe ʻana i ka pole inert gas pale.Hoʻohana ʻo ia i ka Ar a me nā kinoea inert ʻē aʻe ma ke ʻano he kinoea pale nui, me ke kinoea Ar a i ʻole Ar maʻemaʻe i hui pū ʻia me kahi kinoea ikaika liʻiliʻi (e like me O2 ma lalo o 2% a i ʻole CO2 ma lalo o 5%) no ka hoʻoheheʻe ʻana.ʻO ke ala hoʻoheheʻe o ka wili arc.Hāʻawi ʻia ka uea MIG i nā wili a i ʻole nā pili i nā papa.Ke hoʻohana nei kēia ʻano hoʻoheheʻe i ke ahi wela ma waena o ka uwea wili hoʻomau i hānai ʻia a me ka mea hana e like me ke kumu wela, a hoʻohana ʻia ke kinoea i hoʻokuʻu ʻia mai ka nozzle lama e pale i ke arc no ka wili.
2. Pōmaikaʻi:
He mea maʻalahi no ka welding ma nā kūlana like ʻole, a ʻoi aku ka wikiwiki o ka welding a me ka helu deposition kiʻekiʻe.Hoʻopili ʻia ka wiliwili arc pale MIG i ka wiliwili ʻana o ka hapa nui o nā metala nui, me ke kila kalapona a me ke kila kila.He kūpono ka MIG arc welding no ke kila kila, aluminika, magnesium, keleawe, titanium, koho a me nā nickel alloys.Hiki ke hana ʻia ka wiliwili wahi arc me ka hoʻohana ʻana i kēia ʻano wili.
3.Atention：
A. ʻO ke kahe o ke kinoea pale e ʻoi aku ka maikaʻi o 20-25L / min.
B. ʻO ka lōʻihi o ke arc ke hoʻomaluʻia ma kahi o 4-6mm.
C. ʻAʻole maikaʻi loa ka mana o ka makani i ka wiliwili.Ke ʻoi aku ka wikiwiki o ka makani ma mua o 0.5m/s, pono e lawe ʻia nā hana pale makani;e hoʻolohe i ka ea e pale aku i ka pōʻino i ka mea hana.
D. Hiki i ka hoʻohana ʻana i ka pulsed arc i kēia manawa ke loaʻa i kahi arc spray stable, ʻoi aku ka maikaʻi no ka hoʻopili ʻana i ke kila kila, ka pā lahilahi, ka kuʻi ʻana a me ke kuʻi ʻana i luna.
E. E ʻoluʻolu e hoʻohana i ka hui kinoea Ar+2% O2 e wiliwili i ke kila kuʻilima kalapona haʻahaʻa loa, mai hoʻohana i ke kila kuʻihao hui ʻia ʻo Ar a me CO2.
F. E wehe pono i ka aila, ka ʻōpala a me ka lepo lepo ma ka wahi wili i ka wā wili.
