He hana koʻikoʻi ka welding i ke kūkulu ʻana i ka hapa nui o nā mea i hana ʻia me ke kila a me ka alumini.ʻO ka lōʻihi o ka hale holoʻokoʻa a me ka holomua o ka papahana e hilinaʻi pinepine i ka maikaʻi o ka weld.No laila, ma waho aʻe o nā pono kūpono kūpono, pono ʻoe e ʻike pehea e hoʻopili ʻia ai kēlā me kēia mea.ʻO kekahi o nā mea hoʻololi i ke kaʻina holoʻokoʻa ʻo ke ʻano welding.No nā kumu o kēia pou, e nānā wale mākou i ka wili arc me nā electrodes i uhi ʻia.
He aha ka wiliwili lima arc?
He maʻalahi loa ka hana holoʻokoʻa.ʻO ia kekahi o nā ʻano hana wiliwili kaulana loa.Aia ia i ka hoʻoheheʻe ʻana i ka uhi me ka electrode consumable me ka mea welded ma o ke arc uila.Hana ʻia ka hapa nui o nā hana me ka lima a ʻo ka maikaʻi o ka hana ma muli o ke akamai o ka welder.Eia nō naʻe, aia nā kumu e noʻonoʻo ai inā makemake ʻoe e hana ʻoihana.Pono ʻoe e nānā, ma waena o nā mea ʻē aʻe:
pololei a me ka ʻokoʻa o ke kumu o kēia manawa, ʻo ia hoʻi he mīkini wiliwili kaulana
uwea me ka paʻa electrode
uwea lepo me ka pipili electrode
ʻano mahiole a me nā mea ʻē aʻe
Ma waho aʻe o ka ʻenehana welding ponoʻī, he mea nui ke koho ʻana i ke anawaena electrode no ka mea welded.Me ka ʻole o ia, ʻaʻole hiki ke hana i kahi weld maikaʻi.He aha kāu e hoʻolohe ai e hauʻoli i ka hopena hopena?
Ke koho ʻana i ke anawaena electrode no ka mea hana - pono ʻoe e ʻike!
ʻO ke koho ʻana o ke anawaena electrode no ka mea welded ma ke ʻano MMA e pili ana i ka mānoanoa o ka weld a i ʻole nā mea i wili ʻia.He mea nui hoʻi ke kūlana āu e wili ai.ʻO ka maʻamau, hiki ke manaʻo ʻia ʻo nā anawaena mai kahi 1.6mm a hiki i 6.0 mm.He mea nui ʻaʻole ʻoi aku ke anawaena o ka electrode ma mua o ka mānoanoa o ka mea āu e manaʻo ai e weld.Pono e liʻiliʻi.Ma ka palapala e pili ana i ka welding e ʻike ʻoe i ka nui o ke anawaena o ka electrode e like me ka hiki.ʻO kēia neʻe ka ʻoi aku ka waiwai.No laila, ʻoi aku ka maikaʻi o nā mea me ka mānoanoa o 1.5 mm a 2.5 mm me kahi electrode me kahi ʻāpana keʻa o 1.6 mm.Pehea ma nā hihia ʻē aʻe?
Nā laʻana o ka mānoanoa mea a me ke anawaena electrode kūpono.
No ka ʻike maikaʻi ʻana i ke koho ʻana o ke anawaena electrode no ka mea hana, ma lalo ʻoe e ʻike ai i kahi papa inoa pōkole o nā mānoanoa mea kaulana loa a me ke anawaena electrode maikaʻi loa.
Mānoanoa mea - Electrode diameter
1.5mm a 2.5mm - 1.6mm
3.0mm a 5.5mm - 2.5mm
4.0mm a 6.5mm - 3.2mm
6.0mm a 9.0mm - 4.0mm
7.5mm a 10mm - 5.0mm
9.0mm i 12mm - 6.0mm
