Ukuhlaziywa Okujulile Kwezinto Zokushisela zikagesi kanye neThermal Resistance Spot Welding Materials

I-Resistance spot welding iyindlela esetshenziswa kakhulu ekukhiqizeni, ikakhulukazi ezimbonini zezimoto kanye ne-aerospace. Ukusebenza kwale nqubo kuncike kakhulu ekuziphatheni kukagesi nokushisa kwezinto ezihilelekile. Kulesi sihloko, sizohlola umhlaba oyinkimbinkimbi walezi zakhiwo ezibonakalayo kanye neqhaza lazo elibalulekile ekushiseleni indawo yokumelana.

I-Electric Conductivity: Isihluthulelo Sokushisela Okuphumelelayo

1. Ukuqonda I-Electrical Conductivity: I-electric conductivity isilinganiso sekhono lempahla lokuqhuba umsinga kagesi. Ku-resistance spot welding, izinto zokusebenza (imvamisa izinsimbi) kufanele zithwale amandla kagesi ngendlela efanele ukuze zikhiqize ukushisa endaweni yokushisela. Izinto ezine-conductivity kagesi ephezulu, njengethusi ne-aluminium, zikhethwa kuma-electrode ngoba zisiza ukuhamba kukagesi, zenze umthombo wokushisa ogxilile endaweni yokuxhumana.
2. Iqhaza Esizukulwaneni Sokushisa: Uma amandla kagesi edlula ezintweni zokusebenza, ukumelana kwazo kukagesi kubangela ukuthi zishise ngenxa yokushisisa kwe-Joule. Lokhu kushisisa kwendawo kuthambisa izinto, kuzivumela ukuthi zihlanganiswe ndawonye endaweni yokushisela. I-conductivity kagesi ephezulu kuma-electrode iqinisekisa ukulahlekelwa okuncane kokushisa, okwenza inqubo yokushisela isebenze kahle.
3. Ukukhetha Okubalulekile: I-Copper kanye nama-alloys ayo, njenge-copper-chromium ne-copper-zirconium, yizinqumo ezithandwayo zama-electrode welding ngenxa yokuhamba kahle kagesi. Kodwa-ke, izinto ze-electrode kufanele futhi zimelane nokucindezeleka kwemishini nokugqoka ngesikhathi senqubo yokushisela.

I-Thermal Conductivity: Ukulinganisa Ukusabalalisa Ukushisa

1. Ukuqonda Conductivity Thermal: I-Thermal conductivity ikala ikhono lempahla lokuqhuba ukushisa. Ku-resistance spot welding, kubalulekile ukulawula ukusatshalaliswa kokushisa ukuze uvimbele ukungqubuzana noma ukulimala kwezingcezu zokusebenza. I-thermal conductivity ephansi ezintweni ezishiselwe kusiza ukuqukatha ukushisa ngaphakathi kwendawo yokushisela.
2. Ukuvimbela Ukushisisa ngokweqile: Izinto ezinokusebenza okuphezulu kwe-thermal, njengethusi, zingasusa ngokushesha ukushisa kude nendawo yokushisela. Nakuba lesi sakhiwo sinenzuzo kuma-electrode ukuvimbela ukushisa ngokweqile, kubalulekile ukusebenzisa izinto ezinokuguquguquka okuphansi kwe-thermal kuma-workpieces. Lokhu kuqinisekisa ukuthi ukushisa kugxile endaweni yokushisela, okuvumela ukujoyina okuphumelelayo ngaphandle kokusabalalisa ukushisa okukhulu.
3. Ukuthuthukisa Inhlanganisela Yezinto Ezibalulekile: Ukufinyelela ibhalansi efanele phakathi kokusebenza okuphezulu kukagesi kuma-electrode kanye nokushintshwa kwe-thermal okuphansi ezintweni zokusebenza kubalulekile ekushiseleleni okuphumelelayo kwendawo yokumelana. Onjiniyela bavame ukuhlola izinhlanganisela zezinto ezahlukahlukene ukuze bathole ibhalansi efanelekile yezinhlelo ezithile zokushisela.

Ku-resistance spot welding, ukuqonda ukuguquguquka kukagesi nokushisa kwezinto kubalulekile ekuzuzeni ama-welds athembekile futhi aphezulu. I-electrical conductivity iqinisekisa ukugeleza kwamanje okusebenzayo kokukhiqiza ukushisa, kuyilapho ukulawula ukuhanjiswa kwe-thermal kusiza ukugcina ukugxila kokushisa okufanele endaweni yokushisela. Onjiniyela nabashiseli kufanele bakhethe ngokucophelela futhi balinganisele lezi zakhiwo ezibonakalayo ukuze bazuze imiphumela efiselekayo ezinqubweni ezihlukahlukene zokukhiqiza.
