Ama-alloys e-Copper asetshenziswa kakhulu kuma-elekthronikhi, ezingxenyeni zezimoto, nasezintweni zikagesi zasendlini ngenxa yokuhamba kahle kukagesi, ukumelana nokugqwala, kanye nezakhiwo zemishini. Kodwa-ke, lezi zici ezifanayo zenza ukushisela kwamabala kube nzima kakhulu uma kuqhathaniswa nensimbi noma i-aluminium.
Ukuthola{0}}ikhwalithi ephezulu yokushisela kudinga ukuqonda ukuziphatha kwe-copper alloy nokusebenzisa amasu afanele wokushisela. Lo mhlahlandlela uchaza indlela yokushisela ama-alloys ethusi ngokuphumelelayo usebenzisa i-aumshini wokushisela indawo, enedatha-esekelwe imininingwane nezisombululo ezisebenzayo zokukhiqizwa kwezimboni.
Kungani I-Copper Alloys Kunzima Ukubona I-Weld
Ama-alloys ethusi nawethusi aletha izinselelo eziyingqayizivele zokushisela:
1. I-Thermal Conductivity Ephakeme Kakhulu
Ama-alloys ethusi ahambisa ukushisa ngokushesha izikhathi ezi-7-11 kune-carbon steel.
→ Ukushisa kuhlakazeka kude nendawo yokushisela khona manjalo, okwenza ukwakheka kwe-nugget kube nzima.
2. Ukumelana Kagesi Okuphansi
Ukumelana okuphansi kubangela ukuthi i-current idlule kalula, kunciphisa ukukhiqizwa kokushisa endaweni ehlangene.
→ Lokhu kwandisa amathuba okushisela okubuthakathaka noma ukuhlanganisa okunganele.
3. Fast Ukupholisa Amazinga
Ukupholisa ngokushesha kungaholela ekuqineni, ekuqhekekeni, nasekukhuleni kwe-nugget okungahambisani-ikakhulukazi kwithusi, ithusi, kanye{1}}nezinhlayiya eziphakeme ze-zinc.
Ngenxa yalezi zici, ukusethwa komshini wokushisela indawo okujwayelekile wensimbi akufanelekile kuma-alloys ethusi. Ama-electrode akhethekile nokulawula ipharamitha okunembile kubalulekile.
Ukukhetha ama-Electrode Alungile we-Copper Alloy Welding
1. Khetha Izinto Ezidizayinelwe Izinsimbi Eziphezulu{1}Zokusebenza
Imihlahlandlela yokushisela egunyaziwe iyancoma:
| Uhlobo lwe-Copper Alloy | I-Electrode Enconyiwe |
|---|---|
| Ukusebenza{0}okuphezulu (isb, Cu-Cr, Cu-Zr) |
Ama-electrode ekilasi 1 (ukusabalalisa{1}}ithusi eliqinisiwe) |
| Ama-alloys-aphansi e-conductivity (ithusi, ama-bronze) | Ama-electrode e-copper alloy ekilasi 2 |
Ukukhethwa okulungile kwama-electrode kuqinisekisa ukugeleza kwamanje okuzinzile futhi kunciphisa ukulahlekelwa ukushisa.
2. Sebenzisa ama-Electrode Ahlanganisiwe ane-Tungsten Insert
Ngezicelo eziyinselele ze-copper alloy welding:
- Ama-electrodes e-Tungsten anciphisa ukulahlekelwa ukushisa ku-electrode.
- I-Tungsten inephuzu lokuncibilika3420 degree, ephakeme kakhulu kunethusi.
- Okunconyiwe kwethiphu ye-tungsten:3–4 mm.
- Ithuthukisa kakhulu ukwakheka kwe-nugget futhi inciphisa ukunamathela kwe-electrode.
Lezi zixazululo ze-electrode ziqinisekiswa kabanzi ekukhiqizeni izimoto kanye ne-electronics.
Ukuthuthukisa amapharamitha we-Welding we-Copper Alloy Spot Welding
Ukuze kuzuzwe welds ezinzile, yakhoumshini wokushisela indawokufanele ilungiswe ngemingcele enembayo.
1. Isikhathi Samanje Nese-Welding
- Sebenzisa i-peak current ephansi uma kuqhathaniswa ne-steel welding.
- Nciphisa isikhathi sokushisela ukuze ulondoloze okokufaka okugxilile kokushisa.
- Izinhlelo ze-MFDC (Medium Frequency Direct Current) zinikeza ukulawula okungcono kwamashidi amancane (<1.5 mm).
- Kudingeka-ukushuna kahle kulo lonke uhlobo lwengxube yethusi ngoba izici zikagesi/ezishisayo ziyahlukahluka kakhulu.
2. Amathiphu Okuthuthukisa Inqubo
- Hlanza indawo engaphezulu kahle ukuze ususe uwoyela, ama-oxide, uthuli, nemfucumfucu yokucwenga.
- Sebenzisa amandla okucindezela anele ukuze uqinisekise ukumelana nokuxhumana okuzinzile.
- Sebenzisa ukushisa-amashimu noma ama-interlayers lapho kudingeka.
- Qinisekisa ukuthi isistimu yokushisela kanye nokulawulwa kwamandla kuyalinganiswa njalo.
Ukuxazulula Izinkinga Ezivamile Ze-Copper Alloy Welding
1. I-Electrode Sticking
Imbangela:
- Ukushisa okweqile kusixhumi esibonakalayo
- Ukuthambisa i-Electrode noma ukungcoliswa
Izixazululo:
- Engeza ama-electrode ahlanganisiwe we-tungsten
- Yehlisa yamanje / yehlisa isikhathi sokushisela
- Thuthukisa ukupholisa futhi wenze ukugqoka njalo kwama-electrode
2. Amandla Weld Angenele
Imbangela:
- Ukushisa kuhlakazeka ngokushesha kakhulu
- Ukukhula okungekuhle kwe-nugget
Izixazululo:
- Khulisa amandla okucindezela
- Nweba kancane isikhathi se-weld
- Qinisekisa okukhiphayo okungaguquki okuvela kusilawuli se-welding
- Hlanza i-workpiece ngokucophelela
Imikhuba Engcono Kakhulu Yekhwalithi Ye-Weld Ye-Copper Alloy
Ukugcina{0}}ukuzinza kwesikhathi eside nokuphindaphinda:
- Dala-amajika epharamitha ethile
- Hlola futhi ugqoke ama-electrode njalo
- Sebenzisa ama-weld okuhlola kuwo wonke ama-batch amasha we-alloy
- Rekhoda inhlanganisela yepharamitha eyimpumelelo
- Gada amathrendi ku-weld current, force, nosayizi we-nugget
Lezi zinqubo zehlisa kakhulu izilinganiso zokwehluleka-ezindaweni zokukhiqiza ezinkulu.
Ukuqinisekisa Ikhwalithi kanye Nezinqubo Zokuhlola
Ukuze uqinisekise ukwethembeka kwe-weld:
- Ukuhlola okulimazayo (ukugunda, ukungezwani, -ukuhlolwa kwesigaba)
- Ukuhlolwa kwe-peel ukuze uqinisekise ububanzi be-nugget nokuhlanganisa
- Ukuhlolwa okubonakalayo kokuqhekeka, ukubola, nokushisa ngokweqile
- Ukuhlola ukungaguquguquki kwepharamitha kusilawuli nesiguquli
Ukubhala le miphumela kusiza ukugcina izindinganiso zesitifiketi kanye nezidingo zekhwalithi zamazwe ngamazwe.
Isiphetho
Ngezinto ezifanele ze-electrode, izilungiselelo zenqubo ezilungiselelwe, nokulawulwa kwekhwalithi okuqondisiwe, aumshini wokushisela indawoingafinyelela ama-welds aqinile futhi anokwethenjelwa kuma-alloys ethusi. Ngokuphatha ukugeleza kokushisa, ukucindezela kokuzinzisa, nokuvimbela ukuwohloka kwe-electrode, abakhiqizi bangakwazi ukunqoba izinselele ezikhona zokushisela ingxubevange yethusi.
Ukwenza kahle lezi zindlela akuthuthukisi ukusebenza kahle kokushisela kuphela kodwa futhi kuthuthukisa ukuqina komkhiqizo kanye nokungaguquguquki kokukhiqiza ezimbonini ezifana ne-electronics, izimoto, ukugcinwa kwamandla, kanye nezingxenye zikagesi.
