Kune marudzi maviri e beryllium copper alloys.Simba repamusoro beryllium copper alloys (Alloys 165, 15, 190, 290) ine simba rakakwirira kudarika chero ipi zvayo yemhangura yemhangura uye inoshandiswa zvakanyanya mumagetsi emagetsi, switch uye zvitubu.Iyo yemagetsi uye yekupisa conductivity yeiyi yakakwirira-simba alloy inenge 20% yeiyo yakachena mhangura;high-conductivity beryllium copper alloys (alloys 3.10 uye 174) ane simba rakaderera, uye maitiro avo emagetsi anenge anenge 50% yemhangura yakachena, inoshandiswa pamagetsi emagetsi uye relays.Simba repamusoro beryllium copper alloys zviri nyore kupikisa weld nekuda kwekuderera kwemagetsi conductivity (kana yakakwirira resistivity).
Beryllium mhangura inowana simba rayo repamusoro mushure mekupisa kupisa, uye zvese zviri zviviri beryllium mhangura alloys inogona kupihwa mu pre-heated kana kupisa-kurapwa mamiriro.Welding mashandiro anofanira kazhinji kupihwa mune inodziya-yakagadziriswa mamiriro.The welding operation inofanira kazhinji kuitwa mushure mekupisa kupisa.Mukudzivirira welding yeberyllium mhangura, nzvimbo inobatwa nekupisa inowanzova diki, uye haidiwe kuve neberyllium copper workpiece yekupisa kupisa mushure mekupisa.Alloy M25 ndeyemahara-kucheka beryllium yemhangura tsvimbo chigadzirwa.Sezvo iyi alloy iine lead, haina kukodzera kupinza welding.
Resistance spot welding
Beryllium mhangura ine yakaderera resistivity, yakakwirira thermal conductivity uye coefficient yekuwedzera kupfuura simbi.Pakazara, beryllium mhangura ine simba rimwechete kana rakakwirira kupfuura simbi.Paunenge uchishandisa resistance spot welding (RSW) beryllium copper pachayo kana beryllium copper nemamwe maalloys, shandisa yakakwira welding current, (15%), yakaderera voltage (75%) uye ipfupi welding time (50%) .Beryllium mhangura inomirisana nepamusoro welding pressure pane mamwe maalloys emhangura, asi matambudziko anogonawo kukonzerwa nekumanikidzwa kwakadzikira.
Kuti uwane mhedzisiro inowirirana mumhangura alloys, welding michina inofanirwa kunyatso kudzora nguva uye ikozvino, uye AC welding michina inosarudzwa nekuda kwekudzika kwayo kweelectrode tembiricha uye mutengo wakaderera.Welding nguva dze4-8 cycle dzakaburitsa zvirinani.Kana welding simbi dzine zvakafanana ekuwedzera coefficients, tilt welding uye overcurrent welding inogona kudzora kuwedzera kwesimbi kudzikamisa njodzi yakavanzwa yekutsemuka kwemagetsi.Beryllium mhangura nemamwe maalloys emhangura anosungwa pasina kurereka uye overcurrent welding.Kana inclined welding uye overcurrent welding inoshandiswa, nhamba yenguva inoenderana nehupamhi hwebasa rekushanda.
Munzvimbo yekupikisa welding beryllium mhangura nesimbi, kana mamwe maaloyi ekupikisa, zviri nani kupisa chiyero chinogona kuwanikwa nekushandisa maelectrodes ane madiki ekusangana padivi reberyllium mhangura.Iyo electrode zvinhu zvinosangana neberyllium mhangura inofanira kuva nepamusoro conductivity kupfuura workpiece, RWMA2 boka regiredhi electrode yakakodzera.Refractory metal electrodes (tungsten uye molybdenum) ine yakanyanya kunyungudika.Iko hakuna tsika yekunamatira kune beryllium mhangura.13 uye 14 pole electrodes iripo zvakare.Zvakanakira refractory simbi hupenyu hwavo hurefu hwebasa.Zvisinei, nekuda kwekuoma kwema alloys akadaro, kukanganisa kwepamusoro kunogona kuitika.Mvura-yakatonhodzwa maelectrode anozobatsira kudzora tembiricha yekupisa uye kurebesa hupenyu hwe electrode.Zvisinei, pakunama zvidimbu zvitete zvikuru zvemhangura yeberyllium, kushandisa maelectrodes anotonhodzwa nemvura kunogona kukonzera kudzimwa kwesimbi.
Kana musiyano weukobvu pakati peberyllium mhangura uye yakakwira resistivity alloy yakakura kupfuura 5, fungidziro yewelding inofanirwa kushandiswa nekuda kwekushaikwa kweiyo inoshanda yekupisa chiyero.
