Ho na le mefuta e 'meli ea li-alloys tsa koporo tsa beryllium.Li-alloys tsa koporo tsa beryllium tse matla (Alloys 165, 15, 190, 290) li na le matla a phahameng ho feta leha e le efe alloy ea koporo 'me li sebelisoa haholo ho li-connectors tsa motlakase, li-switches le liliba.Motlakase le mocheso oa motlakase oa motsoako ona o matla o ka bang 20% ​​oa koporo e hloekileng;li-alloys tsa koporo tse phahameng tsa beryllium (li-alloys 3.10 le 174) li na le matla a fokolang, 'me motlakase oa tsona o ka bang 50% ea koporo e hloekileng, e sebelisetsoang lihokelo tsa matla le li-relay.Matla a phahameng a beryllium alloys koporo a bonolo ho hanyetsa weld ka lebaka la conductivity ea bona e tlaase ea motlakase (kapa resistivity e phahameng).
Beryllium koporo e fumana matla a eona a phahameng ka mor'a phekolo ea mocheso, 'me li-alloys tsa koporo tse peli tsa beryllium li ka fanoa ka boemo ba pele ho mocheso kapa mocheso.Ts'ebetso ea welding hangata e lokela ho fanoa maemong a kentsoeng mocheso.Ts'ebetso ea welding hangata e lokela ho etsoa kamora kalafo ea mocheso.Ho tjheseletsa tjheseletsa ya koporo ya beryllium, sebaka se amehileng ke mocheso hangata se nyane haholo, mme ha ho hlokehe ho ba le sesebediswa sa koporo sa beryllium bakeng sa kalafo ya mocheso kamora ho tjheseletsa.Alloy M25 ke sehlahisoa sa koporo ea koporo ea beryllium e sa lefelloeng.Kaha motsoako ona o na le loto, ha o tšoanelehe bakeng sa tjheseletsa ea ho hanyetsa.
Resistance spot welding
Koporo ea Beryllium e na le resistivity e tlase, conductivity e phahameng ea mocheso le coefficient ea ho atolosa ho feta tšepe.Ka kakaretso, koporo ea beryllium e na le matla a tšoanang kapa a phahameng ho feta tšepe.Ha u sebelisa ho hanyetsa letheba tjheseletsa (RSW) beryllium koporo ka boeona kapa beryllium koporo le metsoako e meng, sebelisa phahameng tjheseletsa hona joale, (15%), tlaase gagamalo (75%) le khutsoanyane tjheseletsa nako (50%) .Beryllium koporo e mamella likhatello tse phahameng tsa welding ho feta li-alloys tse ling tsa koporo, empa mathata a ka boela a bakoa ke khatello e tlaase haholo.
Ho fumana sephetho se ts'oanang ho li-alloys tsa koporo, lisebelisoa tsa ho tjheseletsa li tlameha ho khona ho laola nako le hona joale ka nepo, 'me lisebelisoa tsa welding tsa AC li khethoa ka lebaka la mocheso oa eona o tlase oa elektrode le theko e tlase.Linako tsa welding tsa 4-8 cycles li hlahisitse litholoana tse ntle.Ha tšepe tjheseletsa le coefficients tšoanang katoloso, sekamesa tjheseletsa le overcurrent tjheseletsa ka laola katoloso ea tšepe ho fokotsa kotsi e patiloeng ea mapetsong tjheseletsa.Beryllium koporo le lisebelisoa tse ling tsa koporo li cheselitsoe ntle le ho thekesela le ho chesehela ho feta tekano.Haeba ho sebelisoa welding le overcurrent welding, palo ea linako e itšetlehile ka botenya ba workpiece.
Sebakeng sa ho hanyetsa tjheseletsa beryllium koporo le tšepe, kapa li-alloys tse ling tse phahameng tsa ho hanyetsa, ho leka-lekana ha mocheso ho ka fumanoa ka ho sebelisa li-electrode tse nang le libaka tse nyenyane tse amanang le lehlakoreng la koporo la beryllium.Lisebelisoa tsa electrode tse amanang le koporo ea beryllium li lokela ho ba le conductivity e phahameng ho feta workpiece, elektrode ea sehlopha sa RWMA2 e loketse.Li-electrode tsa tšepe tse refractory (tungsten le molybdenum) li na le lintlha tse phahameng haholo tsa ho qhibiliha.Ha ho na tšekamelo ea ho khomarela koporo ea beryllium.Li-electrode tsa 13 le 14 li fumaneha hape.Molemo oa litšepe tse refractory ke bophelo ba bona ba nako e telele ea tšebeletso.Leha ho le joalo, ka lebaka la ho thatafala ha li-alloys tse joalo, tšenyo e ka holim'a metsi e ka khoneha.Li-electrode tse pholileng ka metsi li tla thusa ho laola mocheso oa ntlha le ho lelefatsa bophelo ba li-electrode.Leha ho le joalo, ha ho chesetsoa likarolo tse tšesaane haholo tsa koporo ea beryllium, tšebeliso ea li-electrode tse pholileng ka metsi li ka fella ka ho tima tšepe.
Haeba phapang ea botenya pakeng tsa koporo ea beryllium le alloy e phahameng ea resistivity e kholo ho feta 5, ho lokela ho sebelisoa welding ka lebaka la khaello ea tekanyo e sebetsang ea mocheso.
