M'dziko laukadaulo wopangira ndi kuwotcherera, mawonekedwe a maelekitirodi omwe amagwiritsidwa ntchito pamakina owotcherera a mtedza amatenga gawo lofunikira kuti akwaniritse ma welds abwino komanso apamwamba kwambiri. Mapangidwe a maelekitirodiwa amatha kukhudza kwambiri njira yonse yowotcherera, zomwe zimakhudza mphamvu ndi kulimba kwa cholumikizira chomaliza. M'nkhaniyi, tiwona mitundu yosiyanasiyana ya ma elekitirodi, kufunikira kwake, ndi momwe amakhudzira zotsatira zowotcherera.
1. Ma Electrodes Okhazikika:
Ma elekitirodi a Flat ndi amodzi mwa mawonekedwe omwe amagwiritsidwa ntchito kwambiri powotcherera ma nati. Amadziwika ndi mawonekedwe awo osalala, osalala, omwe amatsimikizira kugawa ngakhale kukakamizidwa pa workpiece. Maonekedwewa ndi abwino kwa zipangizo zokhala ndi makulidwe osasinthasintha, chifukwa amatha kupereka weld yunifolomu pamtunda wonse. Ma electrode a Flat amagwiritsidwa ntchito nthawi zambiri pamapangidwe omwe kukongola ndi kumalizidwa kwapamwamba ndikofunikira, chifukwa amachepetsa kupotoza kwapamwamba.
2. Tapered Electrodes:
Ma electrode opangidwa ndi tapered amakhala ndi mawonekedwe owoneka ngati mphero, okhala ndi mfundo yocheperako kunsonga. Kapangidwe kameneka kamayang'ana mphamvu yowotcherera pamalo ang'onoang'ono, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe kulowera ndikofunikira. Ma elekitirodi okhala ndi tapered amagwiritsidwa ntchito ndi zida za makulidwe osiyanasiyana, zomwe zimalola kuwongolera bwino pakuzama kwa weld. Zimakhalanso zopindulitsa pakuwotcherera zida zofananira kapena pomwe mwayi uli ndi malire.
3. Domed Electrodes:
Maelekitirodi okhala ndi domed, monga momwe dzinalo likusonyezera, amakhala ndi malo opindika kapena opindika. Mawonekedwewa amathandizira kugawanitsa mofanana ndikuchepetsa chiopsezo chowononga kapena kuwononga malo a workpiece. Ma elekitirodi okhala ndi dome amagwiritsidwa ntchito nthawi zambiri pakafunika kuwotcherera kolimba komanso kolimba, ndipo mawonekedwe apansi ndi ovuta kwambiri. Ndiwothandiza kwambiri pakuwotcherera zinthu zokhuthala ndipo amatha kutengera kusinthasintha kwakung'ono pakukhazikika kwa workpiece.
4. Ma Electrodes Ozungulira:
Maelekitirodi ozungulira ali ndi mawonekedwe ozungulira, ngati mpira kumapeto. Mapangidwe awa amakulitsa malo olumikizirana pakati pa ma elekitirodi ndi chogwirira ntchito, kuonetsetsa kuti magetsi akuyenda bwino komanso kuchepetsa chiopsezo cha arcing. Ma elekitirodi ozungulira amagwiritsidwa ntchito powotcherera mwachangu kwambiri, pomwe kuwotcherera kosasinthasintha komanso kodalirika ndikofunikira. Ndioyenera kuzinthu zonse zoonda komanso zokhuthala ndipo amatha kukulitsa moyo wa ma elekitirodi chifukwa cha kuchepa kwachangu.
5. Offset Electrodes:
Ma electrode a Offset amakhala ndi kusakhazikika mwadala, pomwe ma elekitirodi amodzi amachotsedwa pang'ono ndi mnzake. Mapangidwe awa ndi opindulitsa kwa mapulogalamu omwe mwayi wopita mbali imodzi ya workpiece ndi yochepa. Pochotsa maelekitirodi amodzi, amatha kufikira madera omwe nthawi zambiri amakhala ovuta kuwapeza, ndikupangitsa kuwotcherera kwa magawo ovuta komanso osawoneka bwino.
Pomaliza, mawonekedwe a maelekitirodi mumakina owotcherera nati ndi chinthu chofunikira kwambiri pakuzindikira momwe ntchito yowotcherera imagwirira ntchito. Kusankhidwa kwa mawonekedwe a electrode kuyenera kutengera zofunikira pakugwiritsa ntchito kuwotcherera, kuphatikiza makulidwe azinthu, mapangidwe olumikizana, komanso mwayi wogwiritsa ntchito. Pomvetsetsa ubwino ndi malire a mawonekedwe osiyanasiyana a electrode, opanga amatha kupanga zisankho zomveka bwino kuti akwaniritse ma welds abwino kwambiri, potsirizira pake kuonetsetsa kudalirika ndi kulimba kwa zinthu zawo.
