Indlela Yokuthola Ikhwalithi Yephoyinti Le-Weld Emishinini Yokushisela I-Resistance Spot

I-Resistance spot welding iyindlela esetshenziswa kakhulu ezimbonini zokukhiqiza ukuze kuhlanganiswe izingxenye zensimbi ngokuphumelelayo.Ukuqinisekisa ikhwalithi yamaphoyinti okushisela kubalulekile ukugcina ubuqotho besakhiwo nokuphepha komkhiqizo wokugcina.Kulesi sihloko, sizoxoxa ngendlela yokuthola ikhwalithi ye-weld point emishini yokushisela indawo yokumelana.

I-Resistance spot welding iyinqubo lapho izingcezu ezimbili zensimbi zihlanganiswa ngokufaka ukushisa nokucindezela ezindaweni ezithile.Izinga lephoyinti lokushisela lincike ezintweni ezahlukahlukene, kufaka phakathi imingcele yokushisela, izakhiwo zezinto ezibonakalayo, kanye nesimo sama-electrode wokushisela.Ukubona nokuqinisekisa ikhwalithi yala maphuzu e-weld kubalulekile ukuvimbela amaphutha nokugcina ukuthembeka kwezingxenye ezishiselwe.

Indlela Yokuthola Ikhwalithi Yephoyinti Le-Weld

1. Ukuhlola Okubonakalayo: Indlela elula yokuthola ikhwalithi yephoyinti le-weld iwukuhlola okubonakalayo.Ama-opharetha anamakhono angahlola izindawo zokushisela ukuze kubonakale ukungalungi njengokuqhekeka, i-voids, noma ukungena okunganele.Ukuhlola okubonakalayo kunikeza impendulo esheshayo futhi ngokuvamile umugqa wokuqala wokuzivikela ekulawuleni ikhwalithi.
2. Ukuhlolwa kwe-Ultrasonic: Ukuhlola kwe-Ultrasonic kuyindlela engacekeli phansi esebenzisa amaza omsindo wemvamisa ephezulu ukuhlola ukwakheka kwangaphakathi kwe-weld.Ingakwazi ukubona ukukhubazeka kwangaphakathi okungenzeka kungabonakali ngokuhlola okubonakalayo, njengokuqhekeka okufihliwe noma izikhala.
3. Ukuhlolwa kwe-X-ray: Ukuhlolwa kwe-X-ray kungenye indlela engonakalisi enikeza isithombe esinemininingwane yesakhiwo sangaphakathi se-weld.Isebenza kahle kakhulu ekutholeni amaphutha angaphakathi nokuqinisekisa ubuqotho bamaphuzu okushisela abalulekile.
4. Weld Current kanye Voltage Monitoring: Ukuqapha i-welding current kanye ne-voltage ngesikhathi senqubo yokushisela kunganikeza ulwazi lwesikhathi sangempela mayelana nekhwalithi ye-weld.Ukuchezuka kumapharamitha acacisiwe kungakhombisa izinkinga nge-weld, njengokuthintana kabi noma ukungahambisani kwezinto.
5. Ukuhlolwa kwe-Shear kanye ne-Tensile: Ukuhlola amandla omshini we-weld, amasampuli angenziwa ngaphansi kokuhlolwa kwe-shear kanye nokuqina.Lokhu kuhlola kunquma ikhono le-weld lokumelana namandla angaphandle futhi kuqinisekise ukuthi ihlangabezana nezicaciso zamandla ezidingekayo.
6. Ukuhlaziywa kweMicrostructural: Ukuhlaziywa kwe-Microstructural kuhilela ukuhlola i-microstructure ye-weld ngaphansi kwesibonakhulu.Le ndlela ingadalula ulwazi mayelana nesakhiwo sokusanhlamvu se-weld, esingaba nomthelela emikhiqizweni yayo.
7. Ukuhlolwa kwe-Dye Penetrant: Ukuhlola ukungena kwedayi kuyindlela esetshenziswa ukuthola ukukhubazeka okungaphezulu kuma-welds.Udayi ongenelayo usetshenziswa endaweni yokushisela, futhi noma yimuphi udayi oweqile uyasulwa.Udayi uzongena emaphutheni angaphezulu, awenze abonakale ngaphansi kokukhanya kwe-UV.
8. Ukuhlolwa Kwezinhlayiya Zezibuthe: Le ndlela ifanele ukubona ukonakala okungaphezulu naseduze kobuso ezintweni ze-ferromagnetic.Izinhlayiya zikamagnetic zisetshenziswa ekushiseleni, futhi noma yikuphi ukuphazamiseka endaweni kazibuthe okubangelwa ukukhubazeka kuyabonakala.

Ukuqinisekisa ikhwalithi yamaphoyinti e-weld emishini yokushisela indawo yokumelana kubalulekile ekugcineni ubuqotho bezingxenye ezishiselwe.Ukusebenzisa inhlanganisela yokuhlola okubonakalayo kanye nezindlela zokuhlola ezingalimazi njengokuhlola i-ultrasonic, ukuhlolwa kwe-X-ray, nokuqapha kwamanje kwe-weld kungasiza ekutholeni amaphutha nokuchezuka kumazinga ekhwalithi.Ukuhlolwa kwemishini kanye nokuhlaziywa kwe-microstructural kuqinisekisa futhi ukuthi amashisela ahlangabezana namandla adingekayo kanye nokucaciswa kwesakhiwo.Ngokusebenzisa lezi zindlela, abakhiqizi bangakhiqiza imikhiqizo eshiselwe ngekhwalithi ephezulu ngokuzethemba.
