Zingaki Izinhlobo Zokuhlukana Kwe-Macroscopic Ezikhona Ku-Resistance Spot Welding?

I-Resistance spot welding iyinqubo evamile futhi ebalulekile ezimbonini ezihlukahlukene, kodwa ingabe wake wazibuza ngezinhlobo ezahlukene zokuqhekeka kwe-macroscopic okungenzeka kule ndlela yokushisela? Kulesi sihloko, sizohlola izinhlobo ezahlukene zokuqhekeka kwe-macroscopic ezingabonwa ekushiseleleni indawo yokumelana.

1. Ukuhlukana Kobuso: Ukuphuka kobuso obuhlangene, okwaziwa nangokuthi "ukuhlukaniswa kobuso," kwenzeka ekuxhumaneni kwezinto ezimbili ezishiselwe. Lolu hlobo lokuphuka luvame ukuxhunyaniswa nekhwalithi yokushisela engeyinhle futhi lungabangelwa izinkinga ezifana nokucindezela okunganele noma imingcele yokushisela engafanele.
2. Inkinobho Yokukhipha: Ukuphuka kwezinkinobho zokudonsa kuhilela ukususwa kwenkinobho yensimbi encibilikisiwe eyenziwe ngesikhathi senqubo yokushisela. Lokhu kungenzeka uma impahla yokushisela ingaboshelwe kahle ezintweni eziyisisekelo, okuholela ekutheni inkinobho ikhishwe ngesikhathi sokuhlolwa.
3. Izinyembezi: Ukuphuka kwezinyembezi kubonakala ngokuklebhuka kwesisekelo esizungeze indawo yokushisela. Lolu hlobo lokuphuka luvamise ukwenzeka uma kunokufaka ukushisa okukhulu noma lapho amapharamitha wokushisela engalawulwa kahle.
4. Ipulaki: Ukuphuka kwepulagi kwenzeka lapho ingxenye yento eyodwa yezinto ezishiselwe ihlukaniswa ngokuphelele nayo yonke enye i-weld. Lolu hlobo lokuphuka lungabangelwa izici ezihlukahlukene, okuhlanganisa ukungcola kuma-electrode wokushisela noma inqubo yokushisela engafanele.
5. I-Edge Crack: Imifantu yonqenqema imifantu eyakha eduze konqenqema lwendawo eshiselwe. Zingabangelwa izici ezihlukahlukene ezifana nokungalungiseki kahle kwezinto noma ukulungiswa kwe-electrode okungalungile.
6. I-Nugget Fracture: Ukuphuka kwe-nugget kuhilela ukwehluleka kwesifunda se-weld esimaphakathi, eyaziwa ngokuthi "i-nugget." Lezi ziqhekeko zibalulekile ngoba zingaphazamisa ubuqotho bayo yonke i-weld. Ukuphuka kwe-Nugget kungabangelwa ingcindezi ye-welding enganele noma imingcele ye-welding engafanele.
7. I-Fissure: Ukuqhekeka kwemifantu kuvame ukuba imifantu emincane noma imifantu ngaphakathi kwempahla yokushisela. Lokhu kungaba inselele ukubona ngokubonakalayo kodwa kungenza buthaka ukwakheka kokushisela. Imifantu ingase yenzeke ngenxa yezinkinga zenqubo yokushisela noma ikhwalithi yezinto ezisetshenziswayo.

Ukuqonda lezi zinhlobo ezahlukene zokuphuka kwe-macroscopic ekushiseleleni indawo yokumelana kubalulekile ukuze kuqinisekiswe ikhwalithi nokwethembeka kwamajoyinti ashiselwe emisebenzini ehlukahlukene. Ama-opharetha abashisela nabahloli kufanele baqaphe ukuze bathole futhi babhekane nalokhu kuphuka ukuze kugcinwe ubuqotho besakhiwo sezingxenye ezishiselwe.

Sengiphetha, i-resistance spot welding ingaholela ezinhlotsheni ezihlukene zokuqhekeka kwe-macroscopic, ngayinye enesethi yayo yezimbangela nemithelela. Ukuhlonza lezi ziqhekeko kanye nokubhekana nezimbangela zazo ezibalulekile ukuze kukhiqizwe amashisela ekhwalithi ephezulu ahlangabezana nezindinganiso eziqinile zezimboni zesimanje.
