Momwe Mungawotchere Ma Alloys a Copper ndi Resistance Spot Welding

Kukaniza kuwotchererandi njira yogwiritsidwa ntchito kwambiri yolumikizirana zosiyanasiyanazitsulo, kuphatikizapo zitsulo zamkuwa. Ukadaulo umadalira kutentha komwe kumapangidwa ndi kukana kwamagetsi kuti apange ma welds amphamvu, olimba. Pali njira zambiri zowotcherera mkuwa, koma mwina simunamvepo za kugwiritsa ntchito amakina kuwotcherera malokuwotcherera aloyi zamkuwa. M'nkhaniyi, tiwona njira yothanirana ndi kuwotcherera ma aloyi amkuwa ndikukambirana njira zazikuluzikulu zomwe zikukhudzidwa.

Kukonzekera zinthu

Choyamba, konzani aloyi mkuwa kuti welded. Chifukwa chapadera cha kuwotcherera malo, mawonekedwe a zinthu sangakhale mawonekedwe achilendo monga chitoliro. Ndi bwino kukonzekera mbale 1-3 mm wandiweyani.

Kuyeretsa zinthu

Asanayambekuwotcherera ndondomeko, muyenera kuonetsetsa kuti zidutswa za aloyi zamkuwa zomwe zilumikizidwe ndi zoyera komanso zopanda zonyansa. Zonyansa zilizonse zapamtunda zidzasokoneza ubwino wa weld. Kuyeretsa kumachitika ndi burashi ya waya kapena mankhwala osungunulira.

Kusankhidwa kwa electrode

Kusankhidwa kwa ma elekitirodi pakuwotcherera malo olimbikira ndikofunikira. Ma elekitirodi ayenera kupangidwa ndi zinthu zomwe zimatha kupirira kutentha kwakukulu komwe kumapangidwa panthawi yowotcherera. Ma elekitirodi amkuwa ali ndi madulidwe abwino kwambiri komanso okhazikika. Nthawi zambiri timagwiritsa ntchito maelekitirodi amkuwa kuti tiwotcherera ma aloyi amkuwa.

Khazikitsani zowotcherera

Kukhazikitsa bwinokuwotcherera magawon'kofunika kwambiri kuwotcherera bwino. Zofunikira kuziganizira ndi:

Welding panopa:Kuchuluka kwa zomwe zimagwiritsidwa ntchito panthawi yowotcherera.

Nthawi yowotcherera:Nthawi yogwiritsira ntchito.

Mphamvu yamagetsi:Kupanikizika kochitidwa ndi electrode pa workpiece.

Makhalidwe enienipamwa magawowa zidzadalira makulidwe ndi kapangidwe ka aloyi yamkuwa yomwe ikuwotchedwa.

Njira yowotcherera

Zowotcherera zikakhazikitsidwa, njira yeniyeni yowotcherera imatha kuyamba. Tikumbukenso kuti pamene kuwotcherera kaloti zamkuwa, ife zambiri kuwonjezera solder pakati pa mfundo ziwiri kukhudzana. Pamene kuwotcherera, workpiece imene solder anawonjezera pabwino pakati maelekitirodi kuonetsetsa kukhudzana magetsi wabwino. Pamene kuwotcherera pakali pano kumagwiritsidwa ntchito, kukana kwa malo okhudzana kumatulutsa kutentha, kuchititsa kuti aloyi yamkuwa ndi solder zitsulo zisungunuke ndikusakanikirana pamodzi. Mphamvu ya electrode imatsimikizira kukhudzana koyenera ndikuthandizira kupanga weld.

Kuziziritsa ndi kuyendera

Pambuyo kuwotcherera, kuwotcherera kuyenera kuloledwa kuziziritsa mwachilengedwe kapena njira zoziziritsa zoyendetsedwa bwino ziyenera kugwiritsidwa ntchito kuti zisapangike zolakwika. Pambuyo kuzirala, weld ayenera kuyang'aniridwa bwino. Izi zikuphatikizapo kufufuza ming'alu, porosity ndi kuphatikizika koyenera. Ngati pali cholakwika chilichonse, chowotchereracho chingafunikire kukonzedwa kapena kukonzedwanso.

Mwachidule, tikachita bwino, kuwotcherera malo okanira ndi njira yabwino kwambiri yolumikizira ma aloyi amkuwa. Potsatira masitepe omwe ali pamwambawa ndikuwongolera mosamala magawo owotchera, ma welds amphamvu komanso odalirika amatha kupangidwa muzitsulo zamkuwa, zomwe zimapangitsa kuti njirayi ikhale chida chamtengo wapatali m'mafakitale osiyanasiyana omwe amagwiritsa ntchito zida zamkuwa.
