Incazelo ejulile ye-Welding Current Curve Emishini Ye-Medium Frequency Inverter Spot Welding

Ijika lamanje lokushisela lidlala indima ebalulekile enqubweni yokushisela yemishini yokushisela ye-medium frequency inverter spot. Imele ukuhluka kwe-welding yamanje ngokuhamba kwesikhathi futhi inomthelela obalulekile kwikhwalithi nezici ze-weld ewumphumela. Lesi sihloko sinikeza incazelo eningiliziwe yejika lamanje lokushisela emshinini wokushisela we-medium frequency inverter spot welding.

1. I-Ramp-Up Yamanje: Ijika lamanje lokushisela liqala ngesigaba sokukhuphuka, lapho i-welding current inyuka kancane kancane isuka kuziro iye kunani elinqunywe kusengaphambili. Lesi sigaba sivumela ukusungulwa kokuxhumana kukagesi okuzinzile phakathi kwama-electrode kanye nezinto zokusebenza. Ubude be-ramp-up kanye nesilinganiso kungalungiswa ngokusekelwe kokubalulekile, ukujiya, kanye nemingcele yokushisela oyifunayo. I-ramp-up yamanje elawulwayo nebushelelezi isiza ekwehliseni ukuphalaza kanye nokuzuza ukwakheka okungaguquki kwe-weld nugget.
2. I-Welding Current Pulse: Ngokulandela i-ramp-up yamanje, i-welding current ingena esigabeni sokushaya kwenhliziyo. Phakathi nalesi sigaba, i-current eqhubekayo isetshenziswa isikhathi esithile, esibizwa ngokuthi isikhathi sokushisela. I-pulse yamanje yokushisela ikhiqiza ukushisa ezindaweni zokuthintana, okubangela ukuncibilika kwendawo kanye nokuqiniswa okulandelayo ukuze kwakhe i-weld nugget. Ubude be-pulse yamanje yokushisela bunqunywa izici ezifana nohlobo lwempahla, ukujiya, kanye nekhwalithi yokushisela efiselekayo. Ukulawula kahle ubude be-pulse kuqinisekisa okokufaka okwanele kokushisa futhi kugwema ukushisa ngokweqile noma ukushisisa kancane kwezinto zokusebenza.
3. Ukubola kwamanje: Ngemva kwe-welding current pulse, yamanje iyabola kancane kancane noma yehle ibuyele kuqanda. Lesi sigaba sibalulekile ekuqiniseni okulawulwayo nasekupholiseni i-weld nugget. Izinga lokubola kwamanje lingalungiswa ukuze kuthuthukiswe izinga lokupholisa futhi kuvinjwe okokufaka ukushisa okudlulele ezindaweni ezizungezile, kuncishiswe ukuhlanekezela kanye nokulondoloza izici zezinto ezibonakalayo.
4. I-Post-Pulse Current: Kwezinye izinhlelo zokusebenza zokushisela, i-post-pulse current isetshenziswa ngemva kwe-welding current pulse nangaphambi kokubola okuphelele kwamanje. I-post-pulse current isiza ekucwengiseni i-weld nugget kanye nasekuthuthukiseni izici zayo zomshini ngokuphromotha ukusakazeka kwesimo esiqinile kanye nokucwengwa kwezinhlamvu. Ubude nobukhulu be-post-pulse current kungalungiswa ngokusekelwe ezidingweni ezithile zokushisela.

Ukuqonda ijika lamanje lokushisela emishinini yokushisela imvamisa ephakathi nendawo kubalulekile ukuze kuzuzwe ukushisela okuseqophelweni eliphezulu nokuthembekile. I-ramp-up elawulwayo, i-welding current pulse, ukubola kwamanje, kanye nokusetshenziswa okungase kube khona kwe-post-pulse current kunomthelela enqubweni yokushisela iyonke, iqinisekisa ukufaka ukushisa okufanele, ukuqiniswa, nokupholisa. Ngokulungiselela ijika lamanje lokushisela ngokusekelwe kumpahla, ukujiya, kanye nezici zokushisela ezifiselekayo, abakhiqizi bangathola imiphumela engaguquki negculisayo ekusetshenzisweni kwabo kokushisela indawo.
