Hiki ke hoʻomaʻemaʻe ʻia ka Beryllium copper me ka momona ʻole a i ʻole ka ʻili a i ʻole ke kuʻi ʻana.Inā ʻeleʻele loa ka ʻili a i ʻole ka oxidized o ka ʻili e ka mālama wela māmā, pono e holoi ʻia e wehe i ka oxide.ʻAʻole e like me ka ʻokikene keleawe ʻulaʻula ʻulaʻula i ʻike ʻia, paʻakikī ke ʻike ʻia ka beryllium oxide ma luna o ka ʻili (i hana ʻia e ka mālama wela i loko o ke kinoea hoʻohaʻahaʻa a i ʻole ke kinoea hoʻohaʻahaʻa), akā pono e wehe ʻia ma mua o ka wili ʻana.

Beryllium Copper Alloy

ʻElua ʻano o ka beryllium copper alloys.Loaʻa ka ikaika kiʻekiʻe o ka beryllium copper alloys (Alloys 165, 15, 190, 290) ma mua o kēlā me kēia keleawe keleawe a hoʻohana nui ʻia i nā mea hoʻohui uila, nā hoʻololi a me nā pūnāwai.ʻO ka uila a me ka thermal conductivity o kēia huila ikaika kiʻekiʻe ma kahi o 20% o ke keleawe maʻemaʻe;kiʻekiʻe-conductivity beryllium keleawe alloys (alloys 3.10 a me 174) i haʻahaʻa ikaika, a me ko lakou uila conductivity mea e pili ana i 50% o ka maemae keleawe, hoʻohana no ka mana connectors a me relays.ʻOi aku ka maʻalahi o nā ʻāpana keleawe beryllium ikaika kiʻekiʻe i ke kūʻē ʻana ma muli o kā lākou conductivity uila haʻahaʻa (a i ʻole ka resistivity kiʻekiʻe).

Loaʻa ka Beryllium copper i kona ikaika kiʻekiʻe ma hope o ka mālama ʻana i ka wela, a hiki ke hoʻolako ʻia nā ʻāpana keleawe beryllium ʻelua ma ke kūlana pre-heated a wela paha.Pono e hoʻolako ʻia nā hana welding ma kahi kūlana wela.Pono e hana ʻia ka hana kuʻi ʻana ma hope o ka mālama ʻana i ka wela.I ke kuʻi ʻana o ke keleawe beryllium, liʻiliʻi loa ka wahi i hoʻopili ʻia i ka wela, ʻaʻole pono e loaʻa kahi mea hana keleawe beryllium no ka mālama wela ma hope o ka wili.ʻO ka Alloy M25 kahi huahana keleawe beryllium ʻoki manuahi.No ka loaʻa ʻana o kēia alloy i ke kēpau, ʻaʻole kūpono ia no ka wili kūʻē.

wiliwili wahi kūʻē

ʻO ka Beryllium copper ka haʻahaʻa haʻahaʻa, ʻoi aku ka kiʻekiʻe o ka thermal conductivity a me ka coefficient o ka hoʻonui ʻana ma mua o ke kila.ʻO ka holoʻokoʻa, ʻoi aku ka ikaika o ka beryllium copper ma mua o ke kila.I ka hoʻohana 'ana i ka resistance spot wili (RSW) beryllium copper pono'ī a i 'ole beryllium copper a me nā mea'ē a'e, e ho'ohana i ke au ku'i ki'eki'e, (15%), ka uila ha'aha'a (75%) a me ka manawa wiliwili pōkole (50%).ʻO ka Beryllium copper ke kūpaʻa i nā kaomi kuʻi kiʻekiʻe ma mua o nā ʻāpana keleawe ʻē aʻe, akā hiki ke kumu i nā pilikia ma muli o nā haʻahaʻa haʻahaʻa.

No ka loaʻa ʻana o nā hopena kūlike i nā ʻāpana keleawe, pono e hiki i nā mea wili ke hoʻomalu pono i ka manawa a me kēia manawa, a ʻoi aku ka maikaʻi o nā mea hana kuʻi AC ma muli o kona haʻahaʻa haʻahaʻa electrode a me ke kumu kūʻai haʻahaʻa.ʻO nā manawa welding o 4-8 cycles i loaʻa nā hopena maikaʻi aʻe.I ka wā e wiliwili ai i nā metala me nā koena hoʻonui like, hiki ke hoʻopaʻa i ka hoʻonui ʻia ʻana o ka metala e hoʻopaʻa i ka pōʻino huna o nā māwae.Hoʻopili ʻia ke keleawe Beryllium a me nā mea hoʻohui keleawe ʻē aʻe me ka ʻole o ka hili ʻana a me ke kuʻi ʻana.Inā hoʻohana ʻia ka welding inclined a me ka overcurrent welding, ʻo ka helu o nā manawa e pili ana i ka mānoanoa o ka mea hana.

Ma ka wiliwili wahi kū'ē o ke keleawe beryllium a me ke kila, a i ʻole nā ​​mea hoʻohui kūʻē kiʻekiʻe ʻē aʻe, hiki ke loaʻa ke koena wela maikaʻi ma o ka hoʻohana ʻana i nā electrodes me nā wahi pili liʻiliʻi ma kekahi ʻaoʻao o ke keleawe beryllium.ʻO ka mea electrode i hoʻopili ʻia me ka beryllium copper e ʻoi aku ka kiʻekiʻe o ka conductivity ma mua o ka mea hana, kūpono kahi electrode hui RWMA2.ʻO nā electrodes metala refractory (tungsten a me molybdenum) he kiʻekiʻe loa nā helu heheʻe.ʻAʻohe manaʻo e pili i ka beryllium copper.Loaʻa pū kekahi 13 a me 14 pole electrodes.ʻO ka maikaʻi o nā metala refractory ko lākou ola lōʻihi.Eia nō naʻe, ma muli o ka paʻakikī o ia mau alloys, hiki ke pōʻino i luna.E kōkua nā electrodes hoʻoluʻu wai i ka mālama ʻana i ka wela wela a hoʻolōʻihi i ke ola electrode.Eia nō naʻe, i ka wā e wiliwili ai i nā ʻāpana lahilahi loa o ka beryllium copper, hiki i ka hoʻohana ʻana i nā electrodes hoʻoluʻu wai ke hopena i ke kinai ʻana o ka metala.

Inā ʻoi aku ka mānoanoa o ka ʻokoʻa ma waena o ka beryllium copper a me ka alloy resistivity kiʻekiʻe ma mua o 5, pono e hoʻohana ʻia ka hoʻoheheʻe projection ma muli o ka nele o ke koena wela.

Kuʻekuʻe projection wiliwili

Hiki ke hoʻoponopono ʻia ka nui o nā pilikia o ka beryllium copper i ka hoʻoheheʻe ʻana i ka wahi kūʻē me ka resistance projection welding (RpW).Ma muli o ka liʻiliʻi o ka wela wela, hiki ke hana i nā hana he nui.ʻO nā metala ʻokoʻa o nā mānoanoa like ʻole he maʻalahi ke wili.Hoʻohana ʻia nā electrodes cross-section a me nā ʻano electrode like ʻole i ke kuʻekuʻe projection e hoʻemi i ka deformation a me ka pipili.ʻOi aku ka pilikia o ka conductivity Electrode ma mua o ka hoʻopaʻa ʻana i nā wahi kuʻi.Hoʻohana mau ʻia nā electrodes 2, 3, a me 4-pole;ʻoi aku ka paʻakikī o ka electrode, ʻoi aku ka lōʻihi o ke ola.

ʻAʻole i loaʻa i nā ʻāpana keleawe palupalu ke kuʻekuʻe ʻana o ka projection kuʻi ʻana, ikaika ka beryllium keleawe e pale aku ai i ka haki ʻana o ka puʻupuʻu mua a hāʻawi i kahi weld piha loa.Hiki ke hoʻopili ʻia ke keleawe Beryllium ma nā mānoanoa ma lalo o 0.25mm.E like me ke kuʻi ʻana o ka wahi kūʻē, hoʻohana pinepine ʻia nā mea hana AC.

Ke kūʻai aku i nā metala ʻokoʻa, aia nā puʻupuʻu i loko o nā alloy conductive kiʻekiʻe.He malleable ka Beryllium copper e kuʻi a hoʻopau paha i nā ʻano convex.Me nā ʻano ʻoi loa.Pono e hana ʻia ka mea hana keleawe beryllium ma mua o ka hoʻomaʻamaʻa ʻana i ka wela e pale ai i ka haki ʻana.

E like me ke kuʻi kuʻi ʻana, ʻo ka beryllium copper resistance projection wiliwili e koi mau i ka amperage kiʻekiʻe.Pono e ho'oikaika 'ia ka mana i ka manawa a me ke ki'eki'e e ho'ohehe'e ai ka protrusion ma mua o ka naha'e.Hoʻoponopono ʻia ke kaomi welding a me ka manawa e hoʻomalu i ka haki ʻana o ka puʻu.ʻO ke kaomi welding a me ka manawa e hilinaʻi pū ʻia i ka geometry bump.E ho'ēmi ka puʻe pahū i nā hemahema weld ma mua a ma hope o ka wili ʻana.

Ka mālama pono ʻana i ka Beryllium Copper

E like me ka nui o nā mea ʻenehana, ʻo ka beryllium copper he pōʻino olakino wale nō ke mālama pono ʻia.He palekana loa ka Beryllium copper ma kona ʻano paʻa maʻamau, ma nā ʻāpana i hoʻopau ʻia, a ma ka hapa nui o nā hana hana.Eia nō naʻe, i loko o kahi pākēneka liʻiliʻi o nā kānaka, ʻoi aku ka maikaʻi o ka inhalation o nā ʻāpana liʻiliʻi i nā maʻi ʻehaʻeha.ʻO ka hoʻohana ʻana i nā mana ʻenekinia maʻalahi, e like me ka hana hoʻoheheʻe ʻana e hoʻoulu i ka lepo maikaʻi, hiki ke hōʻemi i ka pōʻino.

No ka mea liʻiliʻi loa ka heheʻe ʻana o ka welding a ʻaʻole i wehe ʻia, ʻaʻohe pilikia kūikawā ke hoʻomalu ʻia ke kaʻina hana kuʻi keleawe beryllium.Inā koi ʻia kahi kaʻina hana hoʻomaʻemaʻe mechanical ma hope o ke kūʻai ʻana, pono e hana ʻia ma ka wehe ʻana i ka hana i kahi ʻāpana ʻāpana maikaʻi.
