Zamagetsi Zazikulu Zamagetsi ndi Makhalidwe Akunja a Makina Owotcherera a Medium Frequency Inverter Spot

Makina owotcherera apakati pafupipafupi inverter spot ndi chida chomwe chimagwiritsidwa ntchito kwambiri polumikizana ndi zitsulo kudzera pakuwotcherera kwamagetsi. Kuti mumvetsetse ndikugwiritsa ntchito makinawa moyenera, ndikofunikira kudziwa bwino magawo ake amagetsi ndi mawonekedwe akunja. M'nkhaniyi, ife delve mu kiyi magetsi magawo ndi makhalidwe akunja a sing'anga pafupipafupi inverter malo kuwotcherera makina.

1. Zida Zamagetsi Zazikulu: 1.1 Welding Current (Iw): Mphamvu yowotcherera ndi yofunika kwambiri yamagetsi yomwe imatsimikizira kutentha komwe kumachitika panthawi yowotcherera. Imayesedwa mu ma amperes (A) ndipo imatha kusinthidwa kuti ikwaniritse zomwe mukufuna komanso mphamvu. Kuwotcherera pakali pano kumakhudzidwa ndi zinthu monga mtundu wa zinthu, makulidwe, ndi mapangidwe olowa.

1.2 Welding Voltage (Vw): Mphamvu yowotcherera ndi mphamvu yamagetsi yomwe imagwiritsidwa ntchito pa ma elekitirodi owotcherera panthawi yowotcherera. Imayesedwa mu ma volts (V) ndipo imagwira ntchito yofunika kwambiri pakuwongolera kuzama kolowera ndi mtundu wonse wa weld. Mphamvu yowotcherera imakhudzidwa ndi zinthu monga madulidwe azinthu, ma electrode geometry, ndi kasinthidwe kolumikizana.

1.3 Mphamvu Yowotcherera (Pw): Mphamvu yowotcherera ndi yopangidwa ndi mphamvu yowotcherera pano ndi voteji. Zimayimira kuchuluka kwa mphamvu zamagetsi zomwe zimasinthidwa kukhala mphamvu ya kutentha panthawi yowotcherera. Mphamvu yowotcherera imatsimikizira kutentha kwa kutentha ndipo imakhudza mapangidwe a weld nugget. Imayezedwa ndi ma watts (W) ndipo imatha kusinthidwa kuti ipititse patsogolo njira yowotcherera.

2. Mawonekedwe Akunja: 2.1 Nthawi Yowotcherera (tw): Nthawi yowotcherera imatanthawuza nthawi yowotcherera, kuyambira pakuyambika kwakuyenda kwapano mpaka kutha. Nthawi zambiri imayendetsedwa ndi nthawi ya makina owotcherera ndipo imatengera zinthu monga mtundu wazinthu, kapangidwe kazinthu zolumikizana, komanso mtundu womwe mukufuna. Nthawi yowotcherera iyenera kusankhidwa mosamala kuti ikwaniritse kuphatikizika komwe kumafunikira komanso kulumikizana kwazitsulo.

2.2 Electrode Force (Fe): Mphamvu ya elekitirodi ndi kukakamiza komwe kumapangidwa ndi ma elekitirodi owotcherera pa workpiece panthawi yowotcherera. Ndikofunikira pakuwonetsetsa kulumikizidwa koyenera kwa magetsi komanso kulumikizana kwachitsulo ndi chitsulo pakati pa malo ogwirira ntchito. Mphamvu ya elekitirodi nthawi zambiri imayang'aniridwa ndi makina a pneumatic kapena hydraulic system ndipo amayenera kukongoletsedwa potengera momwe zinthu ziliri komanso zofunikira zolumikizana.

2.3 Electrode Geometry: Electrode geometry, kuphatikizapo mawonekedwe, kukula, ndi malo okhudzana, zimakhudza kugawidwa kwamakono ndi kutentha panthawi yowotcherera. Zimakhudza mwachindunji mapangidwe a weld nugget ndi mtundu wonse wa weld. Kukonzekera koyenera ndi kukonza ma elekitirodi ndikofunikira kuti mupeze zotsatira zokhazikika komanso zodalirika zowotcherera.

Kumvetsetsa magawo akuluakulu amagetsi ndi mawonekedwe akunja a makina owotcherera pafupipafupi a sing'anga ma frequency inverter ndikofunikira pakukhathamiritsa njira yowotcherera ndikukwaniritsa ma weld apamwamba kwambiri. Poyang'anira magawo monga kuwotcherera pakali pano, magetsi owotcherera, mphamvu yowotcherera, nthawi yowotcherera, mphamvu ya electrode, ndi geometry yamagetsi amagetsi, oyendetsa amatha kusinthira mikhalidwe yowotcherera kuti igwirizane ndi zofunikira zinazake komanso zolumikizana. Chidziwitso ichi chimathandizira ntchito zowotcherera moyenera komanso zodalirika, kuonetsetsa kuti ma welds amphamvu komanso okhazikika pamafakitale osiyanasiyana.
