Uhlalutyo olunzulu loMbane kunye neThermal Conductivity ye-Resistance Spot Welding Materials

I-Resistance spot welding bubuchule obusetyenziswa kakhulu kwimveliso, ngakumbi kumashishini eemoto kunye ne-aerospace. Ukusebenza kwale nkqubo kuxhomekeke kakhulu kumbane kunye ne-thermal conductivity yezinto ezibandakanyekayo. Kweli nqaku, siza kugocagoca kwihlabathi elintsonkothileyo lezinto eziphathekayo kunye nendima yazo ebalulekileyo ekuxhathiseni i-welding spot.

I-Conductivity yoMbane: Isitshixo kwi-Welding esebenzayo

1. Ukuqonda ukuQhutywa koMbane: I-conductivity yombane ngumlinganiselo wesakhono semathiriyeli ukuqhuba umsinga wombane. Kwindawo yokuwelda, izixhobo zokusebenza (ezidla ngokuba ziintsimbi) kufuneka zithwale ngokufanelekileyo umsinga wombane ukuvelisa ubushushu kwindawo yeweld. Izinto eziphathekayo ezinombane ophezulu, ezifana nobhedu kunye ne-aluminium, zikhethwa kwi-electrodes kuba ziququzelela ukuhamba kombane, ukudala umthombo wokushisa ogxininisiweyo kwindawo yokudibanisa.
2. Indima kwisiZukulwana soBubushushu: Xa umsinga wombane udlula kwizinto zokusebenza, ukuxhathisa kwabo kombane kubangela ukuba bafudumale ngenxa yokufudumala kweJoule. Oku kufudumeza kwendawo kuthambisa izinto, kuvumele ukuba zidityaniswe kwindawo ye-weld. I-conductivity ephezulu yombane kwi-electrodes iqinisekisa ukulahleka kobushushu obuncinci, okwenza inkqubo ye-welding isebenze ngakumbi.
3. Ukukhethwa kwezinto: I-Copper kunye ne-alloys zayo, ezifana ne-copper-chromium kunye ne-copper-zirconium, zikhetho ezidumileyo kwi-welding electrodes ngenxa yombane obalaseleyo. Nangona kunjalo, izixhobo ze-electrode kufuneka zimelane noxinzelelo lomatshini kunye nokunxiba ngexesha lenkqubo ye-welding.

I-Thermal Conductivity: Ukulinganisa ukuhanjiswa kobushushu

1. Ukuqonda i-Thermal Conductivity: I-Thermal conductivity ilinganisa ukukwazi kwesixhobo ukuqhuba ubushushu. Kwindawo yokumelana nokuwelda, kubalulekile ukulawula ukusasazwa kobushushu ukuthintela ukulwa okanye ukonakaliswa kwezixhobo zokusebenza. I-conductivity ephantsi ye-thermal kwizinto ezifakwe kwi-welded inceda ukuquka ukushisa ngaphakathi kwendawo ye-welding.
2. Ukuthintela Ukushisa Okugqithisileyo: Izinto eziphathekayo ezine-conductivity ephezulu ye-thermal, njengobhedu, zinokukhupha ngokukhawuleza ukushisa kude ne-welding point. Ngelixa le propati iluncedo kwii-electrode ukunqanda ukufudumeza, kubalulekile ukusebenzisa imathiriyeli ene-thermal conductivity ephantsi yezixhobo zokusebenza. Oku kuqinisekisa ukuba ubushushu bugxininiswe kwindawo ye-weld, kuvumela ukujoyina okusebenzayo ngaphandle kokusasazwa kobushushu obugqithisileyo.
3. Ukuphucula ukudityaniswa kwezinto: Ukufezekisa ulungelelwaniso oluchanekileyo phakathi kokuhamba kombane okuphezulu kwi-electrode kunye ne-thermal conductivity ephantsi kwizinto zokusebenza kubalulekile kwimpumelelo yokumelana nendawo ye-welding. Iinjineli zihlala zivavanya indibaniselwano yemathiriyeli eyahlukeneyo ukufumana ibhalansi efanelekileyo yosetyenziso oluthile lwe-welding.

Kwindawo yokumelana ne-welding, ukuqonda umbane kunye ne-thermal conductivity yemathiriyeli kubalulekile ekufezekiseni i-welds ethembekileyo kunye nekhwalithi ephezulu. I-conductivity yombane iqinisekisa ukuhamba ngoku ngokufanelekileyo kokuveliswa kobushushu, ngelixa ukulawula ukuqhutyelwa kwe-thermal kunceda ukugcina ubushushu obufanelekileyo kwindawo yokutshisa. Iinjineli kunye ne-welders kufuneka zikhethe ngokucophelela kwaye zilungelelanise ezi zixhobo eziphathekayo ukuze zifezekise iziphumo ezifunwayo kwiinkqubo ezahlukeneyo zokuvelisa.
