Iialloyi zobhedu zisetyenziswa kakhulu kwi-electronics, izinto zemoto, kunye nezixhobo zasekhaya ngenxa yokuqhuba kakuhle kombane, ukuxhathisa ukubola, kunye neempawu zoomatshini. Nangona kunjalo, ezi mpawu zifanayo zenza ukuba ukuwelda kube nzima kakhulu xa kuthelekiswa nentsimbi okanye ialuminiyam.
Ukufumana{0}umgangatho ophezulu wokuwelda kufuna ukuqonda ukuziphatha kwengxubevange yobhedu kunye nokusebenzisa iindlela ezifanelekileyo zokuwelda. Esi sikhokelo sichaza indlela yokuwelda iialloyi zethusi ngempumelelo usebenzisa aumatshini wokuwelda indawo, ngedatha-exhaswayo ukuqonda kunye nezisombululo ezisebenzayo kwimveliso yoshishino.
Kutheni iialloys zeCopper zinzima ukubona iWeld
Iialloyi zobhedu kunye nobhedu zibonakalisa imiceli mngeni eyodwa yokuwelda:
1. I-Thermal Conductivity ephezulu kakhulu
I-alloys zethusi ziqhuba ubushushu amaxesha angama-7-11 ngokukhawuleza kunentsimbi ye-carbon.
→ Ubushushu buyahlukana busuka kwindawo yeweld ngoko nangoko, busenza ukwakheka kwe-nugget kube nzima.
2. Ukunyangwa koMbane okuphantsi
Ukuchasana okuphantsi kubangela ukuba i-current idlule ngokulula, ukunciphisa ukuveliswa kobushushu kwindawo edibeneyo.
→ Oku kwandisa ukubakho kweewelds ezibuthathaka okanye ukudityaniswa okunganelanga.
3. Amaxabiso okupholisa ngokukhawuleza
Ukupholisa ngokukhawuleza kunokukhokelela kwi-porosity, iintanda, kunye nokungahambelani kwe-nugget ukukhula{0}}ingakumbi kwi-brass, bronze, kunye{1}}nezinc alloys eziphezulu.
Ngenxa yale miba, ukuseta umatshini we-welding we-standard we-steel awufanelekanga kwi-alloys yobhedu. Ii-electrode ezikhethekileyo kunye nolawulo oluchanekileyo lweparamitha luyimfuneko.
Ukukhetha ii-Electrodes eziLungileyo kwi-Copper Alloy Welding
1. Khetha iMathiriyeli eyilelwe uPhezulu{1}}Iintsimbi zokuSebenza
Izikhokelo ze-welding ezigunyazisiweyo zicebisa:
| Uhlobo lwe-Copper Alloy | I-Electrode ecetyiswayo |
|---|---|
| {0}}Ukuqhuba okuphezulu (umzekelo, Cu-Cr, Cu{4}}Zr) |
Iielectrode zodidi loku-1 (ukusasazwa{1}}kobhedu olomeleziweyo) |
| Ii-alloys ezisezantsi-zokuqhuba (ibrasi, iibronzi) | Iklasi ye-2 ye-alloy electrode yobhedu |
Ukukhetha okuchanekileyo kwe-electrode kuqinisekisa ukuhamba okuzinzile kwangoku kunye nokunciphisa ukulahleka kobushushu.
2. Sebenzisa i-Electrode edibeneyo ene-Tungsten Insert
Ngezicelo ezicela umngeni kwialloy yobhedu:
- I-Tungsten ifake i-electrodes inciphisa ukulahleka kobushushu kwi-electrode.
- I-Tungsten inendawo yokunyibilika3420 degree, iphezulu kakhulu kunobhedu.
- Isindululo sencam yencam ye-tungsten:3–4 mm.
- Iphucula kakhulu ukubunjwa kwe-nugget kunye nokunciphisa ukunamathela kwe-electrode.
Ezi zisombululo ze-electrode ziqinisekiswa ngokubanzi kwimveliso yeemoto kunye ne-elektroniki.
Ukuphucula i-Welding Parameters kwi-Copper Alloy Spot Spot Welding
Ukufezekisa i-welds ezizinzileyo, yakhoumatshini wokuwelda indawokufuneka iqwalaselwe ngeeparamitha ezichanekileyo.
1. Ixesha langoku kunye ne-Welding
- Sebenzisa i-peak current esezantsi xa kuthelekiswa ne-welding yentsimbi.
- Nciphisa ixesha le-weld ukugcina igalelo lobushushu eligxilileyo.
- Iinkqubo ze-MFDC (Medium Frequency Direct Direct Current) zibonelela ngolawulo olungcono lwamaphepha amancinci (<1.5 mm).
- Kuyafuneka-ulungiso olulungileyo kulo lonke uhlobo lwengxubevange yobhedu kuba iimpawu zombane/ze-thermal ziyohluka kakhulu.
2. Iingcebiso zokuSebenzisa inkqubo
- Coca umphezulu ngokucokisekileyo ukususa ioyile, iioksidi, uthuli, kunye nobutyobo beplating.
- Faka amandla aneleyo okucudisa ukuqinisekisa ukuxhathisa okuzinzileyo.
- Sebenzisa ubushushu-iishim zokugquma okanye izidanga xa zifuneka.
- Qinisekisa ukuba inkqubo ye-welding kunye nolawulo lwamandla lulinganiswa rhoqo.
