Kukho iintlobo ezimbini ze-beryllium copper alloys.Amandla aphezulu e-beryllium copper alloys (I-Alloys 165, 15, 190, 290) inamandla aphezulu kunanoma yiyiphi i-alloy yobhedu kwaye isetyenziswa ngokubanzi kwizixhumi zombane, izitshixo kunye nemithombo.I-conductivity yombane kunye ne-thermal ye-alloy yamandla aphezulu malunga ne-20% yobhedu olucocekileyo;i-high-conductivity beryllium copper alloys (i-alloys 3.10 kunye ne-174) inamandla angaphantsi, kwaye ukuhanjiswa kwawo kombane malunga ne-50% yobhedu olucocekileyo, olusetyenziselwa izixhumi zamandla kunye nokuhanjiswa.Amandla aphezulu e-beryllium i-alloys yobhedu kulula ukuxhathisa i-weld ngenxa ye-conductivity yombane ephantsi (okanye ukuxhathisa okuphezulu).
I-beryllium yobhedu ifumana amandla ayo aphezulu emva kokunyanga ubushushu, kwaye zombini i-beryllium i-alloys yethusi inokubonelelwa kwimeko yangaphambili okanye ekuphathweni ukushisa.Imisebenzi ye-welding kufuneka inikezelwe ngokubanzi kwimeko yokushisa ukushisa.Umsebenzi we-welding kufuneka uqhutywe ngokubanzi emva kokunyanga kobushushu.Kwi-welding ye-beryllium yobhedu, indawo echaphazelekayo yokushisa idla ngokuba yincinci kakhulu, kwaye akufuneki ukuba ube ne-beryllium yobhedu yokwenza unyango lobushushu emva kwe-welding.I-alloy M25 yimveliso yentonga ye-beryllium yokusika yasimahla.Ekubeni le ngxube iqulethe i-lead, ayifanelekanga kwi-welding yokumelana.
Ukumelana neendawo zokuwelda
I-beryllium yobhedu ine-resistiveivity ephantsi, i-conductivity ephezulu ye-thermal kunye ne-coefficient yokwandisa kunentsimbi.Ngokubanzi, i-beryllium yobhedu inamandla afanayo okanye aphezulu kunentsimbi.Xa usebenzisa i-resistance spot welding (RSW) i-beryllium yobhedu ngokwayo okanye i-beryllium yobhedu kunye nezinye i-alloys, sebenzisa i-welding current ephezulu, (15%), i-voltage ephantsi (75%) kunye nexesha elifutshane le-welding (50%) .Ubhedu be-beryllium bumelana noxinzelelo oluphezulu lwe-welding kunezinye i-alloys zethusi, kodwa iingxaki zinokubangelwa ziingcinezelo eziphantsi kakhulu.
Ukufumana iziphumo ezihambelanayo kwii-alloys zethusi, izixhobo ze-welding kufuneka zikwazi ukulawula ngokuchanekileyo ixesha kunye nexesha langoku, kunye nezixhobo ze-welding ze-AC zikhethwa ngenxa yokushisa kwe-electrode ephantsi kunye neendleko eziphantsi.Amaxesha e-Welding emijikelezo ye-4-8 avelise iziphumo ezingcono.Xa ukuwelda isinyithi kunye coefficients ukwandiswa efanayo, welding tilt kunye overcurrent welding inokulawula ukwandiswa kwentsimbi ukunciphisa ingozi efihlakeleyo yokuqhekeka welding.I-beryllium yobhedu kunye nezinye iialloys zobhedu zidityaniswe ngaphandle kokuthambeka kunye ne-overcurrent welding.Ukuba i-welding inclined kunye ne-welding overcurrent isetyenzisiweyo, inani lamaxesha lixhomekeke kubukhulu be-workpiece.
Kwindawo yokumelana ne-welding beryllium copper kunye nentsimbi, okanye ezinye iialloys ezixhathisayo eziphezulu, ibhalansi ye-thermal engcono inokufunyanwa ngokusebenzisa i-electrodes enemigangatho emincinci yokudibanisa kwicala le-beryllium yobhedu.Izinto ze-electrode ezidibanisa nobhedu lwe-beryllium kufuneka zibe ne-conductivity ephezulu kune-workpiece, i-electrode ye-RWMA2 ye-grade grade ifanelekile.Ii-electrodes zetsimbi ezichasayo (i-tungsten kunye ne-molybdenum) zineendawo eziphezulu zokunyibilika.Akukho mkhuba wokunamathela kwi-beryllium copper.I-13 kunye ne-14 yee-electrode ze-pole ziyafumaneka.Inzuzo yeentsimbi eziphikisayo bubomi babo benkonzo ende.Nangona kunjalo, ngenxa yobunzima be-alloys ezinjalo, umonakalo ophezulu unokwenzeka.I-electrode epholileyo yamanzi iya kunceda ukulawula iqondo lokushisa kunye nokwandisa ubomi be-electrode.Noko ke, xa udityaniswa iziqendu ezibhityileyo zeberyllium yobhedu, ukusetyenziswa kwee-electrode ezipholiswe ngamanzi kunokubangela ukucinywa kwesinyithi.
Ukuba umehluko wobunzima phakathi kwe-beryllium yobhedu kunye ne-alloy resistivity alloy inkulu kune-5, i-welding ye-projection kufuneka isetyenziswe ngenxa yokungabikho kwe-balance balance thermal.
