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 Ezizibuthe: Le ndlela ifanele ukuhlonza amaphutha angaphezulu 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 ama-welds ahlangabezana namandla adingekayo kanye nokucaciswa kwesakhiwo. Ngokusebenzisa lezi zindlela, abakhiqizi bangakhiqiza imikhiqizo eshiselwe ngekhwalithi ephezulu ngokuzethemba.
