Mawonekedwe a Electrode ndi Zida Zopangira Makina Owotcherera a Pakatikati Pafupipafupi

Medium frequency spot kuwotcherera ndi njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale opangira kujowina zitsulo.Chimodzi mwazinthu zofunika kwambiri zomwe zimakhudza ubwino wa ma welds a malo ndi mapangidwe ndi mapangidwe a maelekitirodi omwe amagwiritsidwa ntchito popanga.Nkhaniyi ikufotokoza mbali zosiyanasiyana za mawonekedwe a elekitirodi ndi kusankha zinthu kwa sing'anga pafupipafupi malo kuwotcherera makina.

Maonekedwe a ma elekitirodi amatenga gawo lofunikira kuti akwaniritse zowotcherera pamalo okhazikika komanso odalirika.Maonekedwe a electrode amatsimikizira kugawidwa kwamakono ndi kupanikizika pa malo owotcherera.Nthawi zambiri, maelekitirodi athyathyathya, owongoka, komanso owoneka ngati dome ndi zosankha zofala.Ma electrode a Flat amapereka malo olumikizirana okulirapo, kugawa kuwotcherera pano mofanana.Ma elekitirodi osongoka amaunjikiza kwambiri mphamvu ya magetsi pamalo enaake, zomwe zimachititsa kuti pakhale kutentha kwakukulu.Maelekitirodi opangidwa ndi dome amapereka mgwirizano pakati pa ziwirizi, zomwe zimapangitsa kuti kutentha kumayendetsedwa ndi kugawanika.

Zomwe Zimakhudza Mawonekedwe a Electrode:

1. Makulidwe a Zinthu:Zida zokhuthala nthawi zambiri zimafunikira ma elekitirodi athyathyathya kuti zitsimikizire kugawa kwa kutentha kofanana, pomwe maelekitirodi owoneka ngati dome ndi oyenera kuzinthu zocheperako.
2. Welding Panopa:Mafunde apamwamba amawotchera amayendetsedwa bwino ndi maelekitirodi owongoka, kupewa kutenthedwa.Mafunde apansi angagwiritsidwe ntchito ndi ma elekitirodi athyathyathya kuti aziwotcherera mofanana.
3. Mtundu Wazinthu:Zida zosiyanasiyana zimakhala ndi madulidwe osiyanasiyana amagetsi.Maelekitirodi osongoka amawakonda pazinthu zotsika kwambiri, pomwe ma elekitirodi athyathyathya amagwira ntchito bwino ndi zida zowongolera kwambiri.

Kusankhidwa kwa Zinthu za Electrode:Kusankhidwa kwa ma elekitirodi kumakhudza kwambiri mtundu wa weld komanso moyo wautali wamagetsi.Zipangizo zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo ma aloyi amkuwa, ma alloys a refractory, ndi zida zophatikizika.

1. Zida za Copper:Izi zimayamikiridwa kwambiri chifukwa cha matenthedwe abwino kwambiri komanso malo osungunuka kwambiri.Amachotsa bwino kutentha, kusunga umphumphu wa electrode.Komabe, iwo akhoza kuvutika ndi kuvala ndi kukakamira nkhani.
2. Refractory Alloys:Tungsten ndi molybdenum ndi zitsanzo za alloys refractory.Ali ndi malo osungunuka kwambiri ndipo amagonjetsedwa kwambiri ndi kutentha ndi kuvala.Komabe, amatha kukhala osasunthika komanso osasunthika kwambiri kuposa ma aloyi amkuwa.
3. Zophatikiza:Izi zimaphatikiza ubwino wa zipangizo zosiyanasiyana.Mwachitsanzo, copper-tungsten composite imapereka kutentha kwabwino komanso kulimba poyerekeza ndi ma elekitirodi amkuwa.

M'malo apakati pafupipafupi kuwotcherera mawanga, mawonekedwe a electrode ndi kusankha kwazinthu ndizofunikira kwambiri zomwe zimakhudza mtundu ndi kusasinthika kwa ma welds.Mainjiniya ndi opanga ayenera kuganizira mozama zinthu monga makulidwe azinthu, kuwotcherera pano, komanso mtundu wazinthu posankha mawonekedwe a electrode.Kuphatikiza apo, kusankha koyenera kwa zida za elekitirodi, kaya zosakaniza zamkuwa, ma aloyi amkuwa, kapena ma kompositi, zimakhudza kwambiri momwe weld amakhalira komanso moyo wamagetsi.Kuyika bwino pakati pa kapangidwe ka ma elekitirodi ndi kusankha kwazinthu ndikofunikira kuti mukwaniritse zotsatira zabwino kwambiri zowotcherera.
