Isakhiwo se-electrode somshini wokushisela imvamisa ophakathi nendawo siqukethe izingxenye ezintathu: ikhanda nomsila, induku nomsila. Okulandelayo, ake sibheke izici ezithile zesakhiwo zalezi zingxenye ezintathu.
Ikhanda liyingxenye yokushisela lapho i-electrode ithintana ne-workpiece, futhi ububanzi be-electrode emingceleni yenqubo yokushisela ibhekisela kububanzi bokusebenza kwendawo yale ngxenye yokuxhumana. I-electrode eqondile evamile yokushisela indawo inezinhlobo eziyisithupha zomumo wekhanda: okhonjiwe, oyi-conical, oyindilinga, ogobile, oyisicaba, kanye ne-eccentric, kanye nezici zabo zomumo nezimo ezisebenzayo.
Induku iyi-substrate ye-electrode, ikakhulukazi isilinda, futhi ububanzi bayo bufushanisiwe njengobubanzi be-electrode D lapho kusetshenzwa. Iwusayizi oyisisekelo we-electrode, futhi ubude bayo bunqunywa inqubo yokushisela.
Umsila uyingxenye yokuxhumana phakathi kwe-electrode nokubamba noma exhunywe ngokuqondile engalweni ye-electrode. Kuyadingeka ukuqinisekisa ukudluliswa okubushelelezi kwe-welding current kanye ne-electrode pressure. Ukumelana nokuxhumana kwendawo yokuxhumana kufanele kube kuncane, kuvalwe ngaphandle kokuvuza kwamanzi. Ukuma komsila we-electrode welding welding kuncike ekuxhumekeni kwayo nokubamba. Ukuxhumana okuvame ukusetshenziswa kakhulu phakathi kwe-electrode nokubamba ukuxhunywa kwe-tapered shank, okulandelwa ukuxhuma okuqondile kwe-shank kanye noxhumo oluxhunyiwe. Ngokuhambisanayo, kunezinhlobo ezintathu zomumo womsila we-electrode: isibambo esiyikholi, isibambo esiqondile, kanye ne-spiral.
Uma i-taper yesibambo ifana ne-taper yembobo yokubamba, khona-ke ukufakwa nokuhlakazeka kwe-electrode kulula, kuncane kakhulu ukuvuza kwamanzi, futhi kulungele izimo ezicindezelayo; Ukuxhumana kwesibambo esiqondile kunesici sokuqaqa ngokushesha futhi kufanelekile ukushisela ngaphansi kwengcindezi ephezulu, kodwa umsila we-electrode kufanele ube nokunemba okwanele kwe-dimensional ukufanisa eduze imbobo yokubamba futhi uqinisekise ukuhamba kahle. I-drawback enkulu yokuxhuma okufakwe intambo ukungaxhumani kahle kukagesi, futhi impilo yabo yesevisi ayilungile njengaleyo yama-electrode ama-shank tapered.
