Munzvimbo yepakati-frequency DC nzvimbo welding, basa rekumanikidza welding rinoramba riri musoro wakakoshesesa. Ichi chinyorwa chinotarisa mukukosha kwekumanikidzwa kwewelding, maitiro ayo pakuita welding, uye zvinhu zvinoda kunyatsotariswa.
Welding inzira yakaoma inosanganisira kusanganiswa kwezvidimbu zviviri zvesimbi kuburikidza nekushandiswa kwekupisa nekumanikidza. Kunyange kukosha kwekupisa mukuita uku kuchizivikanwa zvakanyanya, basa rekumanikidza welding rinowanzo ramba rakaderera. Mune yepakati-frequency DC spot welding, kudzvanywa kunoitwa panguva yewelding process kunogona kukanganisa zvakanyanya kunaka uye kutendeseka kwejoinhi reweld.
Chimwe chezvikonzero zvakakosha nei kudzvanywa kwewelding kwakakosha iko pesvedzero yayo pakubata kwemagetsi pakati pezvishandiso. Mune yepakati-frequency DC spot welding, inogara ichiyerera yakananga ikozvino inopfuura nepakati pezvishandiso, ichigadzira kuramba uye kugadzira kupisa. Unhu hwekusangana kwemagetsi pakati pezvishandiso zvinogadziriswa zvakananga nekumanikidza kunoshandiswa. Dzvinyiriro isina kukwana inogona kukonzeresa kusashanda zvakanaka kwemagetsi, zvichikonzera kudziyisa kusina kuenzana uye mubatanidzwa usina simba weweld.
Zvakare, welding pressure inoita basa rakakosha mukuwana inopindirana weld nugget, inova dziva resimbi rakanyungudutswa rakaumbwa padanho rekupinza. Kumanikidza kunobatsira kuve nechokwadi chekuti maworkpieces anobatwa zvakasimba pamwe chete, achibvumira kugovera kwakafanana kwekupisa uye kudzvanywa pajoini. Kufanana uku kwakakosha kuburitsa ma welds akasimba, akasimba anosangana nezviyero zveindasitiri uye kuchengetedza zvinodiwa.
Iko kukanganiswa kwekumanikidzwa kwewelding hakugumiri kumhando yejoinhi ye weld. Izvo zvinokanganisawo kushanda kwese kweiyo welding process. Kusakwana kudzvinyirira kunogona kutungamirira kune nguva yakareba yewelding uye kuwedzerwa kwesimba rekushandisa, pakupedzisira kukanganisa kudhura-kushanda kwekushanda kwewelding.
Zvinhu zvakati wandei zvinofanirwa kuverengerwa pakusarudza iyo yakanyanya kunaka welding kumanikidza kune yakapihwa application. Ukobvu hwezvinhu, rudzi rwesimbi dziri kubatanidzwa, saizi ye electrode uye chimiro, uye zvigadziriso zvemuchina wewelding zvese zvinotora basa mukutsanangura iyo yakakodzera kumanikidza paramita. Welding vanoshanda vanofanirwa kudzidziswa kuti vaone zviratidzo zvekusakwana kana kuwandisa kudzvanywa uye kuita shanduko dzinodiwa kuti uwane inodiwa weld mhando.
Mukupedzisa, welding pressure yakakosha zvisingarambiki mune yepakati-frequency DC spot welding. Iyo inobata zvakananga kubatwa kwemagetsi, weld nugget kuumbwa, uye kugona kwese kweiyo welding process. Kuti uwane epamusoro-mhando uye akavimbika welds, welding vanoshanda vanofanirwa kunzwisisa basa rekumanikidza uye kusangana kwayo neakasiyana welding paramita. Nekuita izvi, vanogona kuve nechokwadi chekuti mashandiro avo ekuwelda anosangana nezvinodiwa uye anogadzira majoini akasimba, anogara akasimba.
