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 kwekuomerwa kweiyo practicable thermal balance.
Resistance projection welding
Mazhinji ematambudziko eberyllium mhangura mukupikisa nzvimbo welding anogona kugadziriswa neresistance projection welding (RPW).Nekuda kweiyo diki kupisa kwakakanganisika nzvimbo, akawanda maoparesheni anogona kuitwa.Masimbi akasiyana ehukobvu hwakasiyana ari nyore kubatanidza.Yakapamhama muchinjika-chikamu maelectrodes uye akasiyana maelectrode maumbirwo anoshandiswa mukupikisa projection welding kuderedza deformation uye kunamira.Electrode conductivity ishoma yedambudziko pane ye resistance spot welding.Inowanzoshandiswa ndeye 2, 3, uye 4 pole electrodes;kuoma kwe electrode, hupenyu hurefu.
Akapfava emhangura alloys haaitike kuramba projekiti welding, beryllium mhangura yakasimba zvakakwana kudzivirira nguva isati yakwana kuputika uye inopa weld yakakwana.Beryllium mhangura inogona zvakare kuve fungidziro yakasungirirwa pakukora pazasi 0.25mm.Sezvinei nekupikisa nzvimbo welding, AC michina inowanzo shandiswa.
Paunenge uchitengesa simbi dzakasiyana, mabumps anowanikwa mune yakakwirira conductive alloys.Beryllium mhangura inoumbika zvekuti inogona kubaya kana kuburitsa chero chero chimiro che convex.Kusanganisira zvimiro zvakapinza.Iyo beryllium yemhangura yemhangura inofanirwa kuumbwa isati yapisa kurapwa kuti irege kuputika.
Senge resistance spot welding, beryllium copper resistance projection welding process inoda yakakwira amperage.Simba rinofanira kushandiswa pakarepo uye rakakwirira zvakakwana kuti riite kuti protrusion inyunguduke isati yatsemuka.Welding pressure uye nguva inogadziriswa kudzora bump breakage.Welding pressure uye nguva zvakare zvinoenderana nebump geometry.Iko kuputika kudzvinyirira kunoderedza weld defects isati yasvika uye mushure mekugadzira.
