I ka hana ʻana i kēia wā, ʻo ka ʻenehana welding, ʻoi aku ka nui o ka ʻenehana welding wahi, ke kuleana koʻikoʻi i ka hoʻohui ʻana i nā mea. Hoʻohana nui ʻia nā ʻāpana kila kiʻekiʻe-i nā ʻoihana kaʻa, aerospace, a me nā ʻoihana hana kaumaha ma muli o ko lākou ikaika maikaʻi a me nā ʻano māmā. Eia nō naʻe, ma muli o ko lākou mau waiwai, ʻoi aku ka nui o nā ʻāpana kila ikaika kiʻekiʻe i ke kaʻina hana wili. E kālele ana kēia ʻatikala i ka hoʻohana ʻana omīkini wiliwili wahi alapinepinema ka wiliwili ʻana i nā pepa kiʻekiʻe-ikaika, e noʻonoʻo ana pehea e loaʻa ai ka -kiʻekiʻe kiʻekiʻe wiliwili o nā-pepa ikaika kiʻekiʻe ma omīkini wiliwili wahi alapinepine.
I. Kumu a me na pono o ka Medium Frequency Spot Welding Machines
- Mekini wiliwili wahi alapinepinee hoʻoulu i ka wela ma o ka manawa kiʻekiʻe ma waena o nā electrodes, a laila e loaʻa ai ke kuʻi ʻana o nā mea hana. ʻO ka pinepine o kā lākou hana ʻana mai kekahi mau kilohertz a i mau haneli kilohertz. Hoʻohālikelike ʻia me nā mīkini wiliwili haʻahaʻa haʻahaʻa maʻamau, hāʻawi nā mīkini wiliwili haʻahaʻa haʻahaʻa i nā mea maikaʻi e like me ka maikaʻi o ka wiliwili kiʻekiʻe, ka wela liʻiliʻi -kahi i hoʻopili ʻia, a me ka liʻiliʻi o ka hoʻololi ʻana.
- Ma ke kiko'ī, i ka wā e wiliwili ai i nā pepa ikaika -ki'eki'e, hiki i nā mīkini wiliwili wahi alapinepine ke ho'oku'i koke i ka wela ma ka wahi wili, e ho'emi nui i ka wela-wahi i ho'opilikia 'ia, no laila e pale pono ai i nā pilikia deformation ma muli o ka wela nui o ka mea. Eia hou, hāʻawi nā mīkini wiliwili wahi alapinepine i ka mana pololei o ke au wiliwili, e ʻae ana i ka hoʻololi maʻalahi o nā ʻāpana wili e pili ana i nā mea like ʻole a me nā mānoanoa o nā pepa ikaika -kiʻekiʻe e loaʻa ai nā hopena wiliwili maikaʻi loa.
II. Nā Luʻi Kuʻikuʻi o nā Pepa Kiʻekiʻe -Ikaika
- ʻO nā pepa ikaika kiʻekiʻe, ʻoi aku ka nui o nā mea i hoʻohana ʻia i nā ʻāpana haʻawe kūkulu hale -ʻano maʻamau, loaʻa ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ka hana luhi maikaʻi. Eia nō naʻe, ke kū nei kēia mau mea i kekahi mau pilikia i ka wā o ke kaʻina hana wili. ʻO ka mea mua, paʻakikī loa nā pepa ikaika kiʻekiʻe i ka wela, no laila e maʻalahi lākou i ka wiliwili ʻana a me ka embrittlement. ʻO ka lua, ma muli o ka paʻakikī kiʻekiʻe o nā ʻili -ikaika kiʻekiʻe, ʻaʻole lawa ka ikaika o ka lae weld a i ʻole ka hoʻololi ʻana o ka wiliwili kuʻuna.
III. Kaʻina hana no ka wiliwili kiko kiʻekiʻe -pepa ikaika me nā mīkini wiliwili ʻokoʻa.
No ka hō'oia 'ana i ka wiliwili -ki'eki'e o nā pepa ikaika ki'eki'e ma lalomīkini wiliwili wahi alapinepine, pono e mālama pono ʻia nā ʻāpana kaʻina hana nui:
- ʻO kēia manawa a me ka manawa?
ʻO ka wili o kēia manawa a me ka manawa o ka mīkini wiliwili wahi waena ka mea koʻikoʻi loa. ʻO ka maʻamau, pono e koho ʻia ka nui kūpono o kēia manawa a me ka manawa wili ma muli o ka mānoanoa a me nā hiʻohiʻona o ka pepa -kiʻekiʻe. Hiki i ke au nui a i ʻole ka manawa lōʻihi ke kumu i ka wela nui a i ʻole ke ʻā ʻana-, ʻoiai ʻaʻole lawa ka manawa a i ʻole ka manawa pōkole hiki ke alakaʻi i ka ikaika ʻole o ke kiko weld.
- Paʻi Electrode?
Hoʻopilikia nui ka puʻe electrode i ka maikaʻi wili. ʻO ke kaomi electrode kūpono e hōʻoia i ka pilina maikaʻi o nā mea i ka wā o ke kaʻina hana kuʻi, hoʻomaikaʻi i ka conductivity a me ka thermal conductivity o ka weld point. I ka manawa like, hiki i ke kaomi kūpono ke pale pono i ka deformation welding.
- Ke Kaʻina Hana a me ke kuhikuhi ʻana?
No nā kūlana e koi ana i ka wiliwili ʻana i nā pepa kiʻekiʻe -ikaika nui, hiki i ke kaʻina wiliwili kūpono a me ke kuhikuhi ʻana ke hōʻemi i ka hoʻololi ʻana o ka wiliwili a hoʻomaikaʻi i ka maikaʻi wiliwili piha. Hoʻohana maʻamau ʻia kahi kaʻina kuʻihao lele lele e hōʻemi i ke koʻikoʻi koʻikoʻi.
IV. Hoʻomalu i ka hana maʻamau
- Hoʻomaʻamaʻa mua?
No nā lau mānoanoa ki'eki'e -ikaika, hiki ke hana 'ia ka ho'oma'ama'a ho'oma'ama'a ma mua o ka wiliwili 'ana no ka ho'emi 'ana i ke kaumaha wela i ka wā o ke ka'ina wiliwili a pale i ka hiki 'ana mai o nā māwae.
- ʻO ka hoʻonui ʻana i ka palena?
Ma ka hana ma'amau, ma muli o ka nui -ikaika pepa a me ka mānoanoa, pono e ho'opololei mau 'ia nā palena wili e like me ke au, ka manawa, a me ke kaomi ma o ka ho'ā'o wiliwili no ka 'imi 'ana i ka hopena wiliwili maika'i loa.
- Mālama i nā lako?
I ka wā o ka hoʻohana ʻana i kamīkini wiliwili wahi alapinepine, Pono e nānā mau ʻia nā electrodes no ka ʻaʻahu a hoʻololi koke ʻia e hōʻoia i ke kūlana hana maikaʻi loa o nā mea hana a hōʻoia i ka maikaʻi o ka wili.
Ka hopena?
Mekini wiliwili wahi alapinepineloaʻa nā pōmaikaʻi nui a me nā hiʻohiʻona no ka hoʻohana ʻana i nā pepa kiʻekiʻe -ikaika. Ma o ka hoʻonohonoho ʻana i nā ʻāpana kūpono a me ka mana kaʻina hana, hiki ke hoʻokō ʻia ka -kiʻekiʻe kiʻekiʻe o nā pepa ikaika kiʻekiʻe, e hoʻokō i nā koi kiʻekiʻe o ka hana hou no ka maikaʻi a me ka maikaʻi o ka wiliwili. I ka wā e hiki mai ana, me ka ho'onui hou 'ana i ka 'epekema waiwai a me ka 'enehana wiliwili, 'o ka ho'ohana 'ana i nā mīkini wiliwili wahi alapinepine ma ka -ki'eki'e ikaika wili pepa e laha loa ana, me ka hā'awi 'ana i ke kāko'o ikaika no ka ho'ololi 'ana i ka 'oihana māmā a ki'eki'e.
