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 ʻokoʻa o ka mānoanoa ma waena o ka beryllium copper a me ka alloy resistivity kiʻekiʻe ma mua o 5, pono e hoʻohana ʻia ka wiliwī projection ma muli o ka paʻakikī o ke kaulike wela.
Kuʻekuʻe projection wiliwili
Hiki ke hoʻoponopono ʻia ka nui o nā pilikia o ka beryllium copper i ka hoʻopaʻa ʻana i nā wahi 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 maʻamau ʻo 2, 3, a me 4 pole electrodes;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 hoʻohana koke ʻia ka mana a me ke kiʻekiʻe e hoʻoheheʻe ai ka protrusion ma mua o ka haki ʻana.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.
