Emhlabeni wokukhiqiza nobuchwepheshe bokushisela, ukwakheka kwama-electrode asetshenziswa emishinini yokushisela amantongomane kudlala indima ebalulekile ekuzuzeni ukushisela okusebenzayo nokusezingeni eliphezulu. Ukwakheka kwalawa ma-electrode kungathinta kakhulu inqubo yokushisela iyonke, kuthinte amandla nokuqina kwejoyinti lokugcina lokushisela. Kulesi sihloko, sizocubungula izimo ezihlukahlukene ze-electrode, ukubaluleka kwazo, nokuthi ziwuthonya kanjani umphumela wokushisela.
1. Ama-Flat Electrodes:
Ama-electrode ayisicaba angenye yezindlela ezijwayelekile zama-electrode ezisetshenziswa ekushiseleni amantongomane. Zibonakala ngokubushelelezi kwazo, indawo eyisicaba, okuqinisekisa ukusatshalaliswa okulinganayo kwengcindezi ku-workpiece. Lo mumo ulungele izinto ezinogqinsi olungaguquki, njengoba unganikeza i-weld efanayo kuyo yonke indawo. Ama-electrode ayisicaba avame ukusetshenziswa ezinhlelweni lapho ubuhle nokuqedwa kwengaphezulu kubalulekile, njengoba kunciphisa ukuhlanekezela kwendawo.
2. Ama-Electrode Ahlanganisiwe:
Ama-electrode anama-tapered anomumo ofana ne-conical noma wedge, anephoyinti elincanyana ekugcineni. Lo mklamo ugxilisa amandla okushisela endaweni encane, okwenza ifaneleke lapho ukungena kubalulekile khona. Ama-electrode anama-tapered avame ukusetshenziswa nezinto eziwugqinsi oluhlukahlukene, okuvumela ukulawula okungcono kokujula kwe-weld. Futhi ziwusizo ekushiseleni izinto ezingafani noma lapho ukufinyelela kunqunyelwe khona.
3. Ama-Electrode Anamandla:
Ama-electrode adotiwe, njengoba negama liphakamisa, anendawo egobile noma enedome. Lo mumo usiza ukusabalalisa ingcindezi ngokulinganayo ngenkathi kunciphisa ubungozi bokulimaza noma ukulimaza indawo yokusebenza. Ama-electrode adomiwe avame ukusetshenziswa lapho kudingeka i-weld eqinile neqinile, futhi ukubukeka kwendawo akubalulekile kangako. Zisebenza kahle kakhulu ekushiseleni izinto eziwugqinsi futhi zingamukela ukuhluka okuncane kokucaba kwe-workpiece.
4. Ama-Spherical Electrodes:
Ama-electrode ayindilinga anomumo oyindilinga, ofana nebhola ekugcineni. Lo mklamo ukhulisa indawo yokuxhumana phakathi kwe-electrode kanye ne-workpiece, iqinisekisa ukuqhutshwa kahle kukagesi nokunciphisa ingozi yokufaka i-arcing. Ama-electrode ayindilinga avame ukusetshenziswa ezinhlelweni zokushisela ezinesivinini esikhulu, lapho i-weld engaguquki futhi enokwethenjelwa ibalulekile. Zifanele kokubili izinto ezincane neziwugqinsi futhi zinganweba isikhathi sokuphila se-electrode ngenxa yokuncipha kokuguga.
5. Ama-Electrodes e-Offset:
Ama-electrode e-Offset ane-misalignment ngamabomu, lapho i-electrode eyodwa isuka kancane kwenye. Lo mklamo unenzuzo ezinhlelweni zokusebenza lapho ukufinyelela ohlangothini olulodwa lwe-workpiece kunqunyelwe. Ngokususa i-electrode eyodwa, ingafinyelela ezindaweni ngokuvamile okunzima ukufinyelela kuzo, inike amandla ukushiselwa kwezingxenye eziyinkimbinkimbi ne-asymmetrical.
Sengiphetha, ukuma kwama-electrode emishinini yokushisela amantongomane kuyisici esibalulekile ekunqumeni ikhwalithi nokusebenza kahle kwenqubo yokushisela. Ukukhethwa komumo we-electrode kufanele kusekelwe ezidingweni ezithile zohlelo lokushisela, okuhlanganisa ukushuba kwempahla, ukwakheka okuhlangene, kanye nokufinyelela kucwecwe lokusebenza. Ngokuqonda izinzuzo nemikhawulo yokwakheka kwe-electrode ehlukene, abakhiqizi bangenza izinqumo ezinolwazi ukuze bafinyelele ama-welds angcono kakhulu, ekugcineni baqinisekise ukwethembeka nokuqina kwemikhiqizo yabo.
