Kunezinhlobo ezimbili zama-alloys ethusi e-beryllium.Amandla aphezulu ama-alloys ethusi e-beryllium (Ama-alloys 165, 15, 190, 290) anamandla aphezulu kunanoma iyiphi i-alloy yethusi futhi asetshenziswa kakhulu kwizixhumi zikagesi, ukushintshwa neziphethu.I-conductivity kagesi kanye ne-thermal yale alloy yamandla aphezulu cishe i-20% yethusi elihlanzekile;i-high-conductivity beryllium copper alloys (ama-alloys 3.10 no-174) anamandla aphansi, futhi ukuqhutshwa kwawo kagesi cishe ku-50% yethusi ehlanzekile, esetshenziselwa izixhumi zamandla kanye nama-relay.Amandla aphezulu e-beryllium alloys yethusi kulula ukumelana ne-weld ngenxa yokuguquguquka kwawo okuphansi kagesi (noma ukumelana okuphezulu).
I-Beryllium yethusi ithola amandla ayo aphezulu ngemva kokwelashwa kokushisa, futhi womabili ama-alloys ethusi e-beryllium anganikezwa esimweni sokushisisa kwangaphambili noma esiphathwe ngokushisa.Imisebenzi yokushisela kufanele ngokuvamile inikelwe esimweni esiphethwe ukushisa.Ukusebenza kwe-welding kufanele kwenziwe ngokujwayelekile ngemuva kokwelashwa kokushisa.Ekushiseleni ukumelana kwe-beryllium yethusi, indawo ethintekile ekushiseni ivamise ukuba yincane kakhulu, futhi akudingekile ukuthi kube nesiqeshana sokusebenzela sethusi se-beryllium sokwelashwa kokushisa ngemva kokushisela.I-alloy M25 iwumkhiqizo wenduku yethusi osika mahhala we-beryllium.Njengoba le alloy iqukethe umthofu, ayifaneleki ukushisela ukumelana.
I-Resistance spot welding
Ithusi le-beryllium linokumelana okuphansi, ukuqhutshwa kwe-thermal okuphezulu kanye ne-coefficient yokunwetshwa kunensimbi.Sekukonke, ithusi le-beryllium linamandla afanayo noma aphezulu kunensimbi.Uma usebenzisa i-resistance spot welding (RSW) i-beryllium yethusi ngokwayo noma ithusi le-beryllium namanye ama-alloys, sebenzisa i-welding current ephezulu, (15%), i-voltage ephansi (75%) kanye nesikhathi esifushane sokushisela (50%) .I-Beryllium yethusi imelana nokucindezela okuphezulu kwe-welding kunamanye ama-alloys ethusi, kodwa izinkinga zingabangelwa ukucindezela okuphansi kakhulu.
Ukuze uthole imiphumela engaguquki kuma-alloys ethusi, imishini yokushisela kufanele ikwazi ukulawula ngokunembile isikhathi nesikhathi samanje, futhi imishini yokushisela ye-AC ikhethwa ngenxa yokushisa kwayo okuphansi kwe-electrode kanye nezindleko eziphansi.Izikhathi zokushisela zemijikelezo engu-4-8 zikhiqize imiphumela engcono.Lapho ushisela izinsimbi ezinama-coefficients afanayo wokunweba, i-welding etshekile kanye ne-overcurrent welding ingalawula ukunwetshwa kwensimbi ukukhawulela ingozi efihliwe yokuqhekeka kokushisela.I-Beryllium yethusi namanye ama-alloys ethusi ashiselwe ngaphandle kokutsheka nokushisela ngokweqile.Uma kusetshenziswa i-welding ethambekele kanye ne-overcurrent welding, inani lezikhathi lincike ekugqineni kwe-workpiece.
Endaweni yokumelana nokushisela i-beryllium yethusi nensimbi, noma amanye ama-alloys aqinile, ibhalansi engcono yokushisa ingatholwa ngokusebenzisa ama-electrode anezindawo ezincane zokuthintana ngasohlangothini lwethusi lwe-beryllium.Izinto ze-electrode ezithintana ne-beryllium yethusi kufanele zibe ne-conductivity ephakeme kune-workpiece, i-electrode yebanga leqembu le-RWMA2 ifanelekile.Ama-electrode ensimbi aphikisayo (i-tungsten ne-molybdenum) anamaphuzu aphezulu kakhulu ancibilika.Akukho ukuthambekela kokunamathela ku-beryllium yethusi.Ama-electrode angu-13 no-14 ayatholakala.Inzuzo yezinsimbi eziphikisayo impilo yabo ende yesevisi.Kodwa-ke, ngenxa yokuqina kwama-alloys anjalo, umonakalo ongaphezulu kungenzeka.Ama-electrode apholile ngamanzi azosiza ukulawula izinga lokushisa lethiphu futhi andise impilo yama-electrode.Nokho, lapho kushiselwa izingxenye ezacile kakhulu zethusi i-beryllium, ukusetshenziswa kwama-electrode apholise amanzi kungase kuphumele ekucimeni kwensimbi.
Uma umehluko wokujiya phakathi kwethusi le-beryllium kanye nengxubevange ephezulu ye-resistivity mkhulu kuno-5, i-projection welding kufanele isetshenziswe ngenxa yokuntuleka kwebhalansi esebenzayo yokushisa.
