M'dziko lazopanga, makina owotcherera ma nati amatenga gawo lofunikira kwambiri pakulumikiza zida mosatetezeka. Makinawa ndi osinthika kwambiri ndipo amapezeka m'mafakitale osiyanasiyana, kuyambira wamagalimoto mpaka omanga. Kuti mukwaniritse ma welds olondola komanso odalirika, ndikofunikira kumvetsetsa mfundo zomwe zimagwiritsidwa ntchito pamakinawa.
Nut spot kuwotcherera ndi njira yomwe imaphatikizapo kugwiritsa ntchito mphamvu zamagetsi kuti apange mgwirizano wamphamvu pakati pa mtedza ndi chogwirira ntchito. Ubwino wa weld umadalira magawo osiyanasiyana, omwe ali ndi gawo lalikulu pakukwaniritsa weld wopambana. Tiyeni tifufuze mfundo zazikuluzikulu za magawo owotcherera awa.
1. Kuwotcherera Pano
Kuwotcherera panopa ndi chimodzi mwa zinthu zofunika kwambiri pa ndondomeko kuwotcherera. Zimatsimikizira kuchuluka kwa kutentha komwe kumapangidwa panthawi ya weld. Kutentha kwakukulu kumapangitsa kutentha kwambiri, komwe kungapangitse kuti kuwotcherera kwakuya komanso kwakukulu. Komabe, kutentha kwambiri kungayambitsenso kupotoza kwa zinthu ndikufooketsa mgwirizano. Chifukwa chake, kusankha njira yowotcherera yoyenera ndikofunikira kuti mukwaniritse zowotcherera zolimba, zokhazikika.
2. Nthawi Yowotcherera
Nthawi yowotcherera ndi chinthu china chofunikira. Imatanthawuza nthawi yomwe ikuyenda pakalipano kudzera mu mtedza ndi workpiece. Nthawi yoyenera kuwotcherera imatsimikizira kuti kutentha komwe kumapangidwa kumakhala kokwanira kuti apange mgwirizano wolimba popanda kuchititsa kutentha kapena kuwotcha. Ndikofunika kupeza njira yoyenera kuti mupange weld wodalirika.
3. Mphamvu ya Electrode
Mphamvu ya elekitirodi, yomwe imadziwikanso kuti kuthamanga kwa kuwotcherera, imakhudza kulumikizana pakati pa ma elekitirodi ndi chogwirira ntchito. Parameter iyi ndiyofunikira kuti mupange weld wokhazikika komanso wofanana. Mphamvu yochepa imatha kupangitsa kuti isalowe bwino, pomwe mphamvu yochulukirapo imatha kuwononga zida zomwe zikulumikizidwa. Kusunga mphamvu yolondola ya ma elekitirodi ndikofunikira kuti ma weld achite bwino.
4. Electrode Geometry
Maonekedwe ndi kukula kwa maelekitirodi omwe amagwiritsidwa ntchito m'makina owotcherera ma nati ndizofunikira kwambiri. Electrode geometry imatha kukhudza kugawa kwapano komanso kukakamiza panthawi yowotcherera. Ndikofunikira kusankha ma elekitirodi omwe amagwirizana ndi zomwe pulogalamuyo ikufuna kuti muwonetsetse kuti ma welds amawotchera komanso kupewa zinthu monga zipsera kapena kupunduka kwambiri.
5. Zinthu Zakuthupi
Zida zomwe zimawotcherera zimagwiranso ntchito kwambiri pozindikira magawo owotcherera. Zida zosiyanasiyana zimakhala ndi ma conductivity osiyanasiyana komanso matenthedwe. Chifukwa chake, ndikofunikira kusintha magawo azowotcherera kuti agwirizane ndi zida zomwe zikukhudzidwa kuti mukwaniritse zomwe mukufuna.
Mwachidule, kumvetsetsa ndi kuwongolera magawo owotcherera pamakina owotcherera a mtedza ndikofunikira kuti tipeze ma welds odalirika komanso osasinthasintha. Posintha mosamalitsa kuwotcherera pakali pano, nthawi, mphamvu ya ma elekitirodi, geometry ya electrode, ndikuganizira zazinthu zakuthupi, opanga amatha kuwonetsetsa kuti zinthu zawo zimakwaniritsa miyezo yapamwamba kwambiri komanso yolimba. Mfundozi zimathandizira kukhazikitsidwa kwa kuwotcherera kogwira mtima ndi makina owotcherera ma nati, kuwapanga kukhala zida zofunika kwambiri pakupanga zamakono.
