I-Resistance spot welding iyinqubo yokushisela esetshenziswa kabanzi ethembela kuma-electrode ukudala ama-welds aqinile futhi athembekile ezintweni ezahlukahlukene.Ukukhethwa kwama-electrode afanele kubalulekile empumelelweni yemisebenzi yokushisela indawo.Kulesi sihloko, sizohlinzeka ngomhlahlandlela ophelele wokuthi ungakhetha kanjani ama-electrode welding welding.
1. Ukuqonda Izinhlobo ze-Electrode
Ama-electrode we-resistance spot welding eza ngezinhlobo ezahlukene, ngalinye lakhelwe izinhlelo ezithile.Izinhlobo ezijwayelekile zama-electrode zifaka:
- I-Copper Electrodes:Lezi zihlukahlukene futhi zilungele inhlobonhlobo yezinto zokwakha, okuhlanganisa insimbi, i-aluminium, nethusi.
- I-Chromium-Copper Electrodes:Ilungele ukushisela izinto ezinamandla kakhulu kanye nezinhlelo zokusebenza ezidinga impilo yama-electrode enwetshiwe.
- I-Tungsten-Copper Electrodes:Zaziwa ngokuqina nekhono lokusingatha izicelo ezishisa kakhulu, ezifana nezinto eziwugqinsi zokushisela.
- I-Molybdenum Electrodes:Isetshenziselwa ukushisela izinto ezingavamile njenge-titanium nasezinhlelweni ezidinga ukumelana nezinga lokushisa eliphezulu.
Ukuqonda izici kanye nokusetshenziswa okuhlosiwe kohlobo ngalunye lwe-electrode kubalulekile ekwenzeni ukukhetha okulungile.
2. Ukuhambisana Kwezinto ezibonakalayo
Khetha ama-electrode ahambisana nezinto ohlose ukuzishisela.Izinto ezihlukile zama-electrode zingase zihlanganyele ngokuhlukile nezinsimbi ezahlukahlukene.Qinisekisa ukuthi ama-electrode afanele ukwakheka kwezinto ezithile kanye nokushuba kwezinto zakho zokusebenza.
3. Ukuma kwe-Electrode nosayizi
Ukuma nobukhulu bama-electrode kudlala indima ebalulekile kwikhwalithi yokushisela kwamabala.Khetha umumo we-electrode ohambisana nejometri yendawo yokushisela.Ubukhulu bama-electrode kufanele bufanele ubuningi be-workpiece ukuze kuqinisekiswe ukusatshalaliswa kokushisa okufanele kanye nokungena ngesikhathi sokushisela.
4. Electrode Coatings
Amanye ama-electrode ambozwe ngezinto ezifana ne-zirconium, ezingathuthukisa ukusebenza kwawo futhi andise ukuphila kwawo.Cabangela ama-electrode amboziwe ukuze asetshenziswe lapho ukushisela okungaguquki kanye nekhwalithi ephezulu kubalulekile.
5. Izindlela Zokupholisa
Ekusetshenzisweni kokushisa okuphezulu, ukupholisa kubalulekile ukuvimbela ukulimala kwe-electrode.Amanye ama-electrode eza nezinhlelo zokupholisa ezakhelwe ngaphakathi, njengama-electrode apholise amanzi, angasiza ukugcina izinga lokushisa lawo futhi andise ukuphila kwawo.
6. Ukulindela Ukuphila Kwe-Electrode
Cabangela isikhathi sokuphila esilindelekile sama-electrode, ikakhulukazi ezindaweni zokushisela ezikhiqiza kakhulu.Nakuba amanye ama-electrode engase abe nesikhathi esifushane sokuphila, abiza kakhulu ukushintshwa.Amanye, njenge-chromium-copper noma ama-electrode e-tungsten-copper, anesikhathi eside sokuphila kodwa angase abize kakhulu ekuqaleni.
7. I-Electrode Maintenance
Ukugcinwa njalo kwama-electrode kubalulekile ukuze kuqinisekiswe ikhwalithi yokushisela engaguquki.Amanye ama-electrode angase adinge ukulungiswa njalo kunamanye.Cabangela ukunethezeka kokulungisa lapho ukhetha ama-electrode wohlelo lwakho lokusebenza.
8. Ukucatshangelwa kwesabelomali
Yize kubalulekile ukukhetha ama-electrode afanele ohlelo lwakho lokusebenza, izingqinamba zesabelomali nazo zingase zibe isici.Linganisa izindleko zama-electrode ngokuphathelene nokusebenza kwawo okulindelekile neminyaka yokuphila.
9. Idumela Lomhlinzeki
Khetha abahlinzeki abathembekile abaziwa ngokuhlinzeka ngama-electrode ekhwalithi ephezulu nokusekelwa kwamakhasimende okuhle kakhulu.Abahlinzeki abathembekile banganikeza isiqondiso ekukhetheni ama-electrode futhi banikeze usizo lapho kudingeka.
Sengiphetha, ukukhethwa kwama-electrode we-resistance welding welding kuhilela ukucatshangelwa ngokucophelela kwezinhlobo zama-electrode, ukuhambisana kwezinto ezibonakalayo, ukwakheka nosayizi, okokunamathelayo, izindlela zokupholisa, ubude besikhathi sokuphila kwama-electrode, izidingo zokunakekelwa, izingqinamba zesabelomali, kanye nesithunzi somphakeli.Ngokucabangela lezi zici, ungenza izinqumo ezinolwazi futhi uqinisekise ukusebenza okuphumelelayo kokushisela ngama-welds aqinile futhi athembekile.
