Kodi Fusion Nugget ndi chiyani? Njira Yamapangidwe a Fusion Nugget mu Medium-Frequency Inverter Spot Welding

Munjira yowotcherera mawanga apakati pafupipafupi, kupangidwa kwa nugget yophatikizika kumagwira ntchito yofunika kwambiri pakukwaniritsa weld wamphamvu komanso wodalirika. Nkhaniyi ikufuna kufotokoza lingaliro la fusion nugget ndikuwunika momwe amapangidwira muzowotcherera mawanga apakati-frequency inverter spot.

1. Fusion Nugget: The fusion nugget imatanthawuza malo omwe amakhalapo azinthu zosungunuka zomwe zimapangika panthawi yowotcherera. Ndi chifukwa cha kutentha kwakukulu komwe kumapangidwa ndi kukana kwa magetsi pakati pa zida zogwirira ntchito ndi zomwe zimagwiritsidwa ntchito pakalipano. The fusion nugget imayang'anira kulumikiza zida zogwirira ntchito pamodzi, kupanga cholumikizira cholimba komanso chokhazikika.
2. Njira Yamapangidwe a Fusion Nugget: Mapangidwe a fusion nugget mu welding wapakatikati-frequency inverter spot kuwotcherera kumaphatikizapo magawo angapo:

a. Kulumikizana ndi Kuponderezana: Zida zowotcherera zimalumikizidwa ndikuphatikizidwa ndi mphamvu ya elekitirodi. Izi zimatsimikizira kulumikizana kwapamtima ndikukhazikitsa njira yolumikizirana yowotcherera.

b. Kutenthetsa: Zopangirazo zikangolumikizana, mawotchi apamwamba amadutsamo. Kukaniza kwamagetsi pamawonekedwe kumapangitsa kutentha, kukweza kutentha kwambiri pamalo olumikizana. Kutentha kumapangitsa kuti zinthuzo zikhale zofewa ndipo pamapeto pake zimasungunuka, kupanga dziwe losungunuka.

c. Kusakaniza ndi Kulimbitsa: Pamene kuwotcherera kumapitirira kuyenda, zinthu zosungunula zochokera kuzinthu zonsezi zimasakanikirana mu dziwe losungunuka. Izi zimalimbikitsa kufalikira kwa ma atomu ndikuthandizira kupanga zomangira zachitsulo pakati pa zida za workpiece. Dziwe losungunukalo limayamba kulimba pamene kutentha kukutha, kupanga fusion nugget.

d. Kuziziritsa ndi Kulimbitsa: Mphamvu yowotcherera ikazimitsidwa, fusion nugget imayamba kuzizira ndikukhazikika. Mlingo wozizira umakhudza mawonekedwe a microstructure ndi makina a weld. Kuziziritsa kolamulidwa kumalola kupanga magawo omwe amafunidwa zitsulo ndikuonetsetsa kuti mphamvu yowotcherera imayenera.

3. Zomwe Zimayambitsa Kupanga Kwa Nugget Fusion: Zinthu zingapo zimatha kukhudza mapangidwe a fusion nugget mu welding wapakati-frequency inverter spot kuwotcherera:

• Kuwotcherera panopa: Kukula kwa kuwotcherera panopa kumakhudza mwachindunji mbadwo wa kutentha ndipo, motero, kukula ndi kuya kwa nugget yophatikizika.
• Mphamvu ya Electrode: Mphamvu yogwiritsidwa ntchito imatsimikizira malo olumikizana pakati pa zogwirira ntchito, zomwe zimakhudza kugawa kwa kutentha ndi kupanga nugget.
• Nthawi yowotcherera: Kutalika kwa ntchito yowotcherera kumakhudza kuchuluka kwa kutentha komanso kukula kwa nugget yophatikizira.
• Katundu wa zinthu: Ma conductivity, makulidwe, ndi kapangidwe ka zida zogwirira ntchito zimakhudza kukana kwawo kukuyenda kwapano ndipo, chifukwa chake, kupanga kwa kutentha ndi kuphatikizika kwa nugget.

Kuphatikizika kwa nugget ndi gawo lofunikira pakukwaniritsa weld wopambana mu welding wapakati-frequency inverter spot kuwotcherera. Kumvetsetsa momwe ma fusion nugget mapangidwe amapangidwira komanso zomwe zimawakhudzira zitha kuthandiza kukhathamiritsa magawo owotcherera, kuwongolera mtundu wa weld, ndikuwonetsetsa kulimba ndi kulimba kwa cholumikizira chowotcherera. Poyang'anira mosamala kuwotcherera pakali pano, mphamvu ya ma elekitirodi, nthawi yowotcherera, ndi zinthu zakuthupi, ma welder amatha kukwaniritsa mapangidwe osakanikirana komanso odalirika a nugget, zomwe zimatsogolera ku ma welds apamwamba kwambiri.
