Gwero la Kutentha ndi Kuwotcherera M'makina a Copper Rod Butt Welding

Makina owotcherera ndodo zamkuwa ndi zida zofunika kwambiri pamafakitale osiyanasiyana, omwe amadziwika kuti amatha kupanga ma welds amphamvu komanso odalirika m'zigawo zamkuwa. Pakatikati pa njira yowotcherera pamakinawa ndikuwongolera kutentha, komwe kumagwira ntchito yofunika kwambiri kuti ma welds apindule. M'nkhaniyi, tiwona gwero la kutentha ndi kayendedwe ka kuwotcherera pamakina amkuwa.

Gwero la Kutentha: Electrical Arc

Gwero lalikulu la kutentha pamakina owotcherera ndodo zamkuwa ndi arc yamagetsi. Njira yowotcherera ikayamba, arc yamagetsi imapangidwa pakati pa maelekitirodi ndi ndodo yamkuwa imatha. Arc iyi imapanga kutentha kwakukulu, komwe kumakhazikika pamalo olumikizana pakati pa ndodo. Kutentha kopangidwa ndi arc yamagetsi ndikofunikira kusungunula malo a ndodo ndikupanga dziwe losungunuka.

Kuwotcherera: Magawo Ofunikira

Njira yowotcherera pamakina owotcherera ndi ndodo yamkuwa imakhala ndi magawo angapo ofunikira, chilichonse chimathandizira kupanga bwino kolumikizana kolimba komanso kodalirika. Zotsatirazi ndi magawo oyambirira a kayendedwe ka kuwotcherera:

1. Kumangirira ndi Kuyanjanitsa

Gawo loyamba limakhudza kukaniza ndodo zamkuwa zokhazikika bwino ndikuwonetsetsa kuti zikuyenda bwino. Gawo ili ndilofunika kuti mukwaniritse mgwirizano wowongoka komanso wofanana. Makina omangira pamakina owotcherera amasunga bwino ndodo, kulepheretsa kuyenda kulikonse panthawi yowotcherera.

2. Electrical Arc Initiation

Ndodozo zikamangika ndikugwirizanitsa, arc yamagetsi imayambitsidwa. Mphamvu yamagetsi imadutsa mu maelekitirodi ndikuyenda kudutsa kampata kakang'ono pakati pa malekezero a ndodo. Izi zimapanga kutentha kwakukulu komwe kumafunikira pakuwotcherera. Arc imayendetsedwa mosamala kuti isatenthedwe komanso kuti iwonetsetse kutentha kofanana kwa ndodo.

3. Welding Pressure Application

Panthawi imodzimodziyo ndi arc yamagetsi, kuthamanga kwa kuwotcherera kumagwiritsidwa ntchito kubweretsa ndodo yamkuwa moyandikana. Kupsyinjika kumagwira ntchito zingapo zofunika: kumapangitsa kuti zigwirizane, kuonetsetsa kusakanikirana koyenera kwa ndodo, ndikuletsa mipata iliyonse ya mpweya yomwe ingasokoneze khalidwe la weld.

4. Fusion ndi Pool Mapangidwe

Pamene arc yamagetsi ikupitirira, kutentha kopangidwa kumasungunula pamwamba pa ndodo yamkuwa. Izi zimapangitsa kuti pakhale dziwe losungunuka pazitsulo zowotcherera. Kuphatikizika koyenera ndikofunikira kuti mupange weld wamphamvu komanso wodalirika.

5. Welding Hold Pressure

Mphamvu yowotcherera ikazimitsidwa, chowotcherera chimasungidwa kuti dziwe losungunuka liwume komanso kuti weld azizizira. Gawoli limapangitsa kuti mgwirizanowo ukhale wolimba mofanana komanso kuti kukhulupirika kwa weld kumasungidwa.

6. Kuzizira ndi Kukhazikika

Gawo la kukakamiza likatha, cholumikizira chowotcherera chimazizira ndikukhazikika. Kuzizira kumeneku kumatsimikizira kuti cholumikizira cha weld chimakwaniritsa mphamvu zake zonse ndikuti malekezero a ndodo yamkuwa amalumikizidwa bwino.

7. Kutulutsa Kupanikizika

Pomaliza, kukanikiza kumasulidwa kumagwiritsidwa ntchito kumasula cholumikizira chowotcherera kuchokera ku makina omangira. Gawoli liyenera kuyang'aniridwa mosamala kuti lisasokonezeke kapena kuwonongeka kwa weld yomwe yangopangidwa kumene.

Pomaliza, gwero la kutentha m'makina owotcherera ndodo zamkuwa ndi arc yamagetsi, yomwe imatulutsa kutentha kwakukulu komwe kumafunikira pakuwotcherera. Kuzungulira kowotcherera kumakhala ndi magawo ofunikira, kuphatikiza kuwongolera ndi kuwongolera, kuyambitsa kwamagetsi arc, kugwiritsa ntchito kuwotcherera, kuphatikizika ndi mapangidwe a dziwe, kuwotcherera kukakamiza, kuziziritsa ndi kulimba, komanso kutulutsa mphamvu. Kumvetsetsa ndikuwongolera bwino magawowa ndikofunikira kuti mukwaniritse ma welds amphamvu, odalirika, komanso apamwamba kwambiri pamafakitale osiyanasiyana.
