Ngokuthuthuka okusheshayo kwamandla kagesi wezwe lami, izidingo zamajoyinti ezinqeni zethusi ne-aluminium ziya ngokuya zisetshenziswa kabanzi futhi nezidingo ziya ngokuya ngokuya zikhuphuka. Izinqubo ezivamile zokushisela i-copper-aluminium emakethe namuhla zifaka: i-flash butt welding, i-rolling friction welding kanye ne-brazing. Umhleli olandelayo uzokwethulela izici zalezi zinqubo.
I-Friction rolling welding okwamanje ilinganiselwe kuphela kuma-welding bar, futhi izinsimbi ezishiselwe zingaphinde zenziwe zibe amapuleti, kodwa kulula ukubangela ukuqhekeka kwama-interlayers nama-welds.
I-Brazing isetshenziswa kakhulu, futhi isetshenziswa kakhulu ezindaweni ezinkulu nezingajwayelekile ze-copper-aluminium butt, kodwa kunezici ezifana nokushesha okuphansi, ukusebenza kahle okuphansi, kanye nekhwalithi engazinzile.
I-Flash butt welding okwamanje iyindlela engcono kakhulu yokushisela ithusi ne-aluminium. I-Flash butt welding inezidingo eziphezulu kugridi yamandla, futhi kusenokulahlekelwa okuvuthayo. Kodwa-ke, i-workpiece eshiselwe ayinawo ama-pores kanye ne-dross ku-weld seam futhi amandla we-weld seam aphezulu kakhulu. Kuyabonakala ukuthi ukuntula kwayo kusobala, kodwa izinzuzo zayo zingaphezu kobubi bayo.
Inqubo yokushisela i-copper-aluminium flash welding butt iyinkimbinkimbi, futhi amanani epharamitha ahlukahlukene futhi akhawulelana ngokuyinkimbinkimbi, ngalinye elizothinta ikhwalithi yalo yokushisela. Njengamanje, ayikho indlela enhle yokuthola ikhwalithi ye-copper-aluminium welding, futhi iningi lazo lisebenzisa ukutholakala okulimazayo ukuze kuqinisekiswe amandla ayo (ukufinyelela amandla e-aluminium material), ukuze isebenze ngokuthembekile kugridi yamandla.
Izidingo zomshini wokushisela we-copper-aluminium butt welding
1. Izidingo ezibonakalayo zomshini wokushisela izinqe ze-flash;
Ibanga lezinto ezisetshenziswayo zokushisela akufanele libe ngaphansi kwezinga elijwayelekile
2. Shintshela kuzidingo zempahla yomshini wokushisela we-flash butt:
Akufanele kube khona amabala amafutha nezinye izinto ezithinta conductivity lapho Welding ebusweni izingxenye, futhi akufanele kube khona upende phezu Welding ekupheleni surface kanye nezinhlangothi zombili.
3. Shintshela kumshini wokushisela we-flash butt izidingo zokuqala zokulungiselela:
Lapho amandla ezinto ezibonakalayo ephakeme kakhulu, kufanele afakwe kuqala ukuze kuqinisekiswe ubulukhuni obuphansi kanye ne-plasticity ephezulu ye-weldment, ehambisana nokukhishwa kwe-slag yensimbi ye-liquid ngesikhathi sokuphazamiseka.
4. Shintshela kusayizi wempahla womshini wokushisela izinqe ze-flash;
Uma ukhetha ubukhulu bomsebenzi wokushisela ngokusho kobukhulu obushiselayo bomshini wokushisela, khetha inani elibi lethusi kanye nenani elihle le-aluminium (ngokuvamile i-0.3 ~ 0.4). Umehluko wokujiya phakathi kwethusi ne-aluminium akufanele udlule leli nani, ngaphandle kwalokho kuzodala ukugeleza okwanele noma okucasulayo ngokweqile, okuzothinta kakhulu ikhwalithi yokushisela.
5. Izidingo zengxenye yempahla yomshini wokushisela we-flash butt:
Ubuso bokugcina be-weldment kufanele bube buyisicaba, futhi ukusika akufanele kube kukhulu kakhulu, okuzobangela ukukhiqizwa kokushisa okungalingani emikhawulweni yomibili ye-weld futhi kubangele i-weld engalingani.
6. Usayizi wokuvala we-flash butt welding workpiece:
Lapho uvala ukushisela, inani lokushiswa kwe-flash kanye nokuphazamiseka kufanele lengezwe emdwebeni ngokuya ngenqubo yokushisela.
