Kumashishini afana namandla avuselelekayo, ukuhanjiswa kwamandla, ukugcinwa kwebhetri, kunye neenkqubo ze-photovoltaic,oomatshini bokuwelda ekusasazenidlala indima ebalulekileyo ekuveliseni iziqhagamshelo eziguquguqukayo, iibhasi zombane, iiconductors ezihlanganisiweyo, kunye -nokuthembeka okuphezulu kwezixhobo zombane.
Phakathi kwazo zonke iiparamitha zenkqubo, ubushushu be-welding kunye noxinzelelo lwe-welding zezona zinto zibalulekileyo ezimisela umgangatho odibeneyo, amandla omatshini, kunye nokuthembeka kwexesha elide-.
Ulawulo olululo lwale parameters luchaphazela ngokuthe ngqo ukusebenza kwemveliso kwaye lukwaphembelela indlela abasebenzisi abafanele bavavanye ngayo kwaye bakhethe izixhobo ze-welding ze-diffusion.
Esi sikhokelo sichaza amaqondo obushushu kunye noxinzelelo, indlela abasebenza ngayo kunye, kunye nendlela ezi parameters kufuneka ziqwalaselwe xa ufunda malunga ne-welding ye-diffusion okanye ukhetha umatshini ochanekileyo wokuvelisa.
Kutheni iqondo lobushushu kunye noxinzelelo lubalulekile kwi-Diffusion Welding
I-Diffusion welding yinkqubo yokudityaniswa yelizwe-eqinile. Ngokungafaniyo ne-fusion welding, izixhobo azinyibiliki. Endaweni yoko, i-joint yenziwa ngokusasazwa kwe-athomu kwiqondo lokushisa eliphezulu kwaye phantsi koxinzelelo olulawulwayo.
Inkqubo yokudibanisa isekwe kwi:
- I-deformation yeplastiki kwindawo yoqhagamshelwano
- Ukunyuka kwendawo yoqhagamshelwano yokwenene phakathi kwezinto
- Ukufuduka kweAtomic ngaphaya kojongano
- Ukuqulunqwa kwebhondi ye-metallurgical ezinzileyo
- Ukuphelisa i-voids kunye nee-oxides zomhlaba
Ngenxa yokuba akukho kunyibilika kwenzeka, umgangatho we-weld uxhomekeke ikakhulu kwi:
- Ubushushu obaneleyo ukuze kusebenze ukusasazwa kweatom
- Uxinzelelo olwaneleyo lokudala unxibelelwano lomphezulu olusondeleyo
Yiyo loo nto oomatshini bokudibanisa i-diffusion bafuna iinkqubo zokulawula ubushushu obuchanekileyo kunye neenkqubo ezizinzileyo zolawulo loxinzelelo, hayi nje amandla aphezulu aphumayo.
Ubushushu obuqhelekileyo beWelding Ranges
Iqondo lobushushu Umgaqo: 0.6–0.8 of Melting Point
Kwimizi-mveliso, ubushushu be-welding ye-diffusion budla ngokulawulwa60%–80% yobushushu obunyibilikayo besixhobo (Tm).
Olu luhlu luvumela ukusasazwa okusebenzayo kweathomu ngaphandle kokubangela ukunyibilika okanye ukonakala kwesakhiwo.
IiNqanaba zoBuqondo obuqhelekileyo boShishino
| Izinto eziphathekayo | Indawo yokunyibilika ( isidanga ) | Uluhlu lwe-Diffusion Welding ( isidanga) |
Usetyenziso oluqhelekileyo |

| Ubhedu-Intsimbi engatyiwayo | -- | 750–900 | Amalungu esinyithi ahlukeneyo |
Ngaphakathi kolu luhlu, i-welding ye-diffusion inokufikelela kumandla adibeneyo ukuya kuthi ga kwi-90% okanye ngaphezulu kwamandla esiseko, kunye nokuhanjiswa kombane okugqwesileyo kunye nokuzinza komatshini.
Ulawulo lobushushu kuMandla kunye nezicelo zokuGcina
Kwimveliso yokwenyani,{0}}iiprofayile zokufudumeza ezininzi zisetyenziswa kakhulu:
- Inqanaba lokufudumala - kunciphisa uxinzelelo lwangaphakathi
- Inqanaba lokufudumeza eliphambili - livula ukusasazwa kweathom
- Inqanaba lokubamba - lizinzisa inkqubo yokusabalalisa
- Inqanaba lokupholisa elilawulwayo - lithintela iintanda kunye nomonakalo wesakhiwo
Umzekelo, kwi-copper-aluminium composite busbar welding:
- Ukufudumeza ngokuthe ngcembe ukusuka kwiqondo lokushisa ukuya kwi-300℃→ 500℃→ 600 degree
- Oku kuthintela uxinzelelo lwe-thermal olubangelwa ngamazinga ahlukeneyo okwandisa
- Uqinisekisa ukuhlangana okuzinzileyo kunye nemfezeko yesakhiwo
Yiloo nto-umgangatho ophezulu we-diffusion oomatshini bokuwelda kufuneka baxhase amaqondo obushushu alungelelanisiweyo kunye nolawulo oluzinzileyo lwe-thermal, hayi nje ubushushu obuphezulu.
IiRange zoxinzelelo lweWelding eqhelekileyo

Igcina iimeko ezizinzileyo zokusasazwa kokudibanisa
Le ndlela iphucula umgangatho wokudibanisa, ikhusela ukutyibilika kwezinto, kwaye iqinisekisa isakhiwo esidibeneyo.
Ulawulo olulungelelanisiweyo loBubushushu kunye noxinzelelo
I-welding ye-Diffusion ayikona nje "ubushushu obuphezulu + uxinzelelo oluphezulu."
Yiinkqubo yongqamaniso elawulwayophakathi kobushushu kunye noxinzelelo:
- Ubushushu bulawula isantya sokusasazwa
- Uxinzelelo lulawula umgangatho woqhagamshelwano
- Ngokudibeneyo bamisela ukusebenza kakuhle kokudibanisa
Imizekelo evela kwizicelo zamandla:
- Ukuwelda ngentsimbi yobhedu:
~800–900℃+ 12–18 MPa
Ivelisa iileya ezizinzileyo zokusasazwa kwaye inqanda iikhompawundi ezinqabileyo
- Welding yobhedu-aluminiyam:
~600℃+ 18–25 MPa
Ilawula isantya sosasazo kwaye inqande ukukhula kwe-brittle intermetallic layer
Xa idibene ne-atmospheres ekhuselayo (i-argon okanye i-vacuum), i-oxidation iyancitshiswa kwaye i-conductivity edibeneyo iphuculwe ngakumbi.
