Kuwunika kwa Impact of Transition process pa kuwotcherera mu Medium Frequency Inverter Spot Welding Machine (Gawo 2)

M'nkhani yapita, tinakambirana kufunika kwa njira kusintha sing'anga pafupipafupi inverter malo kuwotcherera makina ndi zotsatira zake pa kuwotcherera zotsatira. Gawo lachiwiri ili la mndandanda likufuna kusanthula mopitilira muyeso wa kusintha kwa njira yowotcherera ndikuwunikanso zinthu zina zomwe zingakhudze ubwino wa weld.

1. Electrode Material and Coating: Kusankhidwa kwa zinthu za elekitirodi ndi zokutira kungakhudze kwambiri kusintha kwakusintha ndi kuwotcherera kotsatira. Zida zosiyanasiyana zama elekitirodi zimakhala ndi magetsi komanso matenthedwe amagetsi, zomwe zimatha kukhudza kutulutsa kutentha ndikusuntha panthawi yowotcherera. Zopaka pa maelekitirodi zimathanso kukhudza zinthu monga kukana kukhudzana, moyo wa electrode, komanso kugawa kwa kutentha. Kusankha zida zoyenera za ma elekitirodi ndi zokutira kutengera zomwe zimafunikira kuwotcherera ndikofunikira kuti mukwaniritse kusintha koyenera komanso mtundu wa weld.
2. Kuwongolera Mphamvu ya Electrode: Panthawi yosinthira, kukhalabe ndi mphamvu yokhazikika komanso yoyendetsedwa bwino ya ma elekitirodi ndikofunikira kuti tipeze ma welds odalirika. Kusinthasintha kapena kusagwirizana kwa mphamvu ya ma elekitirodi kumatha kubweretsa kusintha kwa kutentha, kukhudzana kwa zinthu, ndi mtundu wa maphatikizidwe. Makina ena apakati osinthira ma inverter spot kuwotcherera amagwiritsa ntchito njira zowunikira ndi mayankho kuti zitsimikizire zolondola komanso zokhazikika zama elekitirodi panthawi yonseyi. Izi zimathandiza kuti zikhale zofanana komanso zimathandizira kuti weld ikhale yabwino.
3. Kutalika kwa Pulse ndi Frequency: M'makina owotcherera ma frequency inverter spot, kutalika kwa pulse ndi magawo pafupipafupi zitha kusinthidwa kuti ziwongolere njira yosinthira ndi zotsatira zowotcherera. Kuthamanga kwafupipafupi kumalola kusuntha mphamvu mwachangu ndipo kungathandize kuchepetsa madera omwe amakhudzidwa ndi kutentha. Kuthamanga kwamphamvu kwamphamvu kumapereka mphamvu zowongolera kutentha komanso kutha kuwongolera mtundu wa weld muzinthu zina. Kupeza kulinganiza koyenera pakati pa kugunda kwanthawi yayitali komanso pafupipafupi kutengera zinthu zakuthupi ndi mawonekedwe omwe amafunidwa ndi weld ndikofunikira kuti mukwaniritse zotsatira zabwino kwambiri zowotcherera.
4. Kuyang'anira ndi Kuyang'anira Kachitidwe: Kuonetsetsa kusasinthika ndi mtundu wa njira yosinthira, makina owotcherera apakati pafupipafupi a inverter amakhala ndi machitidwe owunikira komanso mayankho. Makinawa amawunika mosalekeza magawo osiyanasiyana monga apano, magetsi, mphamvu ya electrode, ndi kutentha panthawi yowotcherera. Kupatuka kulikonse pamikhalidwe yomwe mukufuna kumatha kuzindikirika ndipo zosintha zitha kupangidwa munthawi yeniyeni kuti mukhalebe ndi kusintha koyenera komanso mtundu wa weld. Kuphatikizika kwa njira zowunikira zapamwamba ndi mayankho kumakulitsa kuwongolera ndi kudalirika kwa njira yowotcherera.

Njira yosinthira pamakina owotcherera ma frequency inverter spot amakhudza kwambiri zotsatira zowotcherera. Zinthu monga ma elekitirodi ndi zokutira, kuwongolera mphamvu ya ma elekitirodi, kutalika kwa kugunda kwamtima komanso pafupipafupi, komanso kukhazikitsidwa kwa njira zowunikira komanso zowunikira zonse zimathandizira kuti kuwotcherera kukhale bwino. Pomvetsetsa ndi kukhathamiritsa njira yosinthira, opanga amatha kukwaniritsa ma welds okhazikika komanso apamwamba pamapulogalamu osiyanasiyana. Mu gawo lotsatira la mndandandawu, tikhala tikuyang'ana gawo la pambuyo pa kuwotcherera komanso chikoka chake pamtundu womaliza wa weld.
