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 e pili ana i 50% o ka maemae keleawe, hoʻohana 'ia 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.

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 hoʻokumu ʻia 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.
I ka wiliwili ʻana i ka beryllium keleawe 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 ka ʻaoʻao 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 pūʻulu 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.
