Njira ya Resistance Spot Welding Copper Alloys

Resistance spot kuwotcherera ndi njira yomwe imagwiritsidwa ntchito kwambiri polumikiza zitsulo zosiyanasiyana, kuphatikiza ma aloyi amkuwa.Njirayi imadalira kugwiritsa ntchito kutentha komwe kumapangidwa ndi kukana kwamagetsi kuti apange ma welds amphamvu, olimba.M'nkhaniyi, tiwona njira yothanirana ndi kuwotcherera ma aloyi amkuwa ndikukambirana njira zazikuluzikulu zomwe zikukhudzidwa.

 Kumvetsetsa I

1. Kukonzekera Zinthu:

Musanayambe kuwotcherera, ndikofunikira kuwonetsetsa kuti zidutswa za aloyi zamkuwa zomwe zilumikizidwe zili zoyera komanso zopanda zowononga.Zonyansa zilizonse zapamtunda zimatha kusokoneza mtundu wa weld.Kuyeretsa kumachitika pogwiritsa ntchito burashi wawaya kapena zosungunulira mankhwala.

2. Kusankhidwa kwa Electrodes:

Kusankha ma elekitirodi ndikofunikira pakuwotcherera pamalo olimbana ndi malo.Ma elekitirodi ayenera kupangidwa ndi zinthu zomwe zimatha kupirira kutentha kwakukulu komwe kumapangidwa panthawi yowotcherera.Ma elekitirodi amkuwa amagwiritsidwa ntchito powotcherera ma aloyi amkuwa chifukwa cha kusinthasintha kwawo komanso kulimba kwawo.

3. Kukhazikitsa Zowotcherera Parameters:

Kuyika zowotcherera moyenera ndikofunikira kuti mukwaniritse bwino.Zofunikira kuziganizira ndi izi:

• Welding current: Kuchuluka kwa magetsi omwe amagwiritsidwa ntchito powotcherera.
• Nthawi yowotcherera: Nthawi yomwe magetsi akugwiritsidwa ntchito.
• Mphamvu yamagetsi: Kukakamiza komwe kumagwiritsidwa ntchito ndi ma elekitirodi.

Makhalidwe enieni a magawowa adzadalira makulidwe ndi kapangidwe ka aloyi yamkuwa yomwe ikuwotchedwa.

4. Njira Yowotcherera:

Zowotcherera zikakhazikitsidwa, njira yeniyeni yowotcherera imatha kuyamba.Zogwirira ntchito zimayikidwa pakati pa maelekitirodi, kuonetsetsa kuti magetsi amalumikizana bwino.Kuwotchera kukagwiritsidwa ntchito, kukana pamalo olumikizirana kumatulutsa kutentha, zomwe zimapangitsa kuti aloyi yamkuwa isungunuke ndikuphatikizana.Mphamvu ya electrode imatsimikizira kukhudzana koyenera ndikuthandizira kupanga weld.

5. Kuzizira ndi Kuyang'ana:

Pambuyo kuwotcherera, ndikofunikira kulola kuwotcherera kuzizirira mwachilengedwe kapena kugwiritsa ntchito njira yoziziritsa yoyendetsedwa bwino kuti zisapangike zolakwika.Akazirala, weld iyenera kuyang'aniridwa kuti ikuwoneka bwino.Izi zikuphatikizapo kufufuza ming'alu, porosity, ndi kusakanikirana koyenera.Ngati pali cholakwika chilichonse, chowotchereracho chingafunikire kukonzedwa kapena kukonzedwanso.

6. Chithandizo cha Post-Weld:

Nthawi zina, chithandizo cha post-weld chingakhale chofunikira kuti muwonjezere makina a weld kapena kuchepetsa kupsinjika kotsalira.Izi zingaphatikizepo njira zochepetsera nkhawa kapena kuchepetsa nkhawa.

Pomaliza, resistance spot kuwotcherera ndi njira yothandiza kwambiri yolumikizira ma aloyi amkuwa atachita bwino.Potsatira ndondomeko zomwe tazitchula pamwambapa ndikuwongolera mosamala magawo otsekemera, ndizotheka kupanga ma welds amphamvu ndi odalirika muzitsulo zamkuwa, kupanga njirayi kukhala chida chamtengo wapatali m'mafakitale osiyanasiyana omwe amagwiritsidwa ntchito mkuwa.
