Pehea e mig weldpaipu kila

ʻO ka wiliwili MIG me ke kinoea ma ke ʻano he mea e pale aku ai i ka kulu metala, ka wiliwili ʻana i ka wai hoʻoheheʻe kiʻekiʻe ke ʻano o ka wiliwili metala arc a me ka wahi wili, i kapa ʻia ʻo MIG arc welding.Me ka uwea kumu paʻa o ke kinoea inert (Ar a i ʻole He) pale arc kuʻihao i kapa ʻia he melting inert gas protection welding.ʻO ka wiliwili MIG me ka hoʻohana ʻana i ka uea metala ma kahi o ka wiliwili tungsten electrode i waho.'ē aʻe a me TIG welding.No laila, hoʻoheheʻe ʻia ka uea ma ka hoʻoheheʻe ʻana i ke arc i loko o ka weld zone.ʻO ka huila uila e like me ka uwea kuʻi mai ka spool e pono ai i ka lama kuʻi.ʻO ke kumu wela Dc uila, akā hoʻohana ʻia ka polarity a me TIG welding no ka ʻaoʻao ʻē aʻe.ʻOkoʻa ke kinoea pale a makemake e hoʻohui i ke kinoea argon e lilo i 1% oxygen e hoʻomaikaʻi i ke kūpaʻa o ke arc.

Hiki ke hoʻohana ʻia ka wiliwili MIG semi-aunoa a i ʻole ka hoʻoheheʻe ʻana i ka mīkini, ākea ākea o nā noi.Hiki i ka wili MIG ke weld i nā ʻano mea like ʻole, akā i nā makahiki i hala iho nei ma muli o ke kalapona a me nā mea hao haʻahaʻa, a ʻoi aku ka hoʻohana ʻana i ka argon-rich hybrid GMAW welding, a ʻaʻole i maʻemaʻe ke kinoea inert maʻemaʻe, ke kinoea inert metala, no laila, hoʻohana mau ʻia ka welding. no ka wiliwili ʻana i ka aluminika, ka magnesium, ke keleawe, ka titanium a me kāna mau ʻāpana a me ke kila kila.Hiki i ka wiliwili MIG ke wiliwili i nā mānoanoa like ʻole o ka mea hana, akā ʻo ka hana maoli ʻo ia ka hoʻoheheʻe ʻana i ka pā aniani, e like me ka mānoanoa o ka lau 2mm ma lalo me ka hoʻohana ʻana i ka wiliwili kinoea inert metala maikaʻi.Hiki i ka MIG welding ke hoʻokō i ka mana naʻauao o nā kūlana kuʻuna āpau.

Loaʻa ka MIG welding i nā ʻano semi-akomi.Hoʻopili ʻia ka welding MIG maʻamau i nā lula o ka seam longitudinal, girth a me ke kūlana pae o ka welding;Hoʻohana nui ʻia ka wili MIG semiautomatic pōkole no ka wiliwili ʻana, weld discontinuous welding a me ke poʻo ipu alumini, hui paipu a me ka hoʻoikaika ʻana i ke apo wili o ka wiliwili.Me ka hoonui ana o MIG kuʻihao palapala noi, wale ma Ar paha He mea paakiki e halawai me ka pono o ka pale kinoea, pela i hoʻomohala i ka inert kinoea e hui i ka uuku nui o ka reactive kinoea e like me oxygen, carbon dioxide kinoea hui e like me ka pale kinoea.Kāhea pinepine ʻia melt reactive gas, welding a MAG.I ka hana kuʻi ʻana o ka hana ʻana, ʻoi aku hoʻi i nā metala kiʻekiʻe a me nā metala nonferrous a me kā lākou mau alloys i ka hana ʻana o ka welding, ʻo MIG welding ke kūlana koʻikoʻi.
