Ukukhethwa Nokugcinwa Kwezinto Ze-Electrode Emishinini Yokushisela I-Medium-Frequency Inverter Spot

Ama-Electrode adlala indima ebalulekile emishinini yokushisela indawo ye-inverter-frequency medium.Ukukhethwa kwezinto ze-electrode kubalulekile ekuzuzeni ama-welds ekhwalithi ephezulu kanye nokuqinisekisa impilo ende yemishini yokushisela.Lesi sihloko sidingida izici okufanele zicatshangelwe lapho ukhetha izinto ze-electrode zemishini yokushisela indawo ye-inverter ye-medium-frequency futhi inikeza isiqondiso ekunakekeleni kwabo.

1. Ukukhethwa Kwezinto Ezibalulekile: Ukukhethwa kwempahla ye-electrode kuncike ezintweni ezimbalwa, okuhlanganisa uhlobo lwe-workpiece, yamanje yokushisela, indawo yokushisela, kanye nekhwalithi yokushisela oyifunayo.Izinto ezisetshenziswa kakhulu ze-electrode zihlanganisa:

   a.I-Copper Electrodes: I-Copper isetshenziswa kabanzi ngenxa ye-conductivity yayo enhle kakhulu ye-thermal, i-conductivity ephezulu kagesi, nokumelana okuhle kokugqoka nokuguqulwa.Ifanele izicelo zokushisela inhloso evamile.

   b.Ama-Electrodes e-Copper-Chromium-Zirconium (CuCrZr): Ama-electrode e-CuCrZr anikeza ukumelana okuthuthukisiwe ekugqokeni okushisayo nokukagesi, okuwenza afanelekele ukushisela okunokushisa okuphezulu kanye nezicelo zamanje.

   c.Ama-Refractory Electrodes: Izinto eziphikisayo ezifana ne-tungsten, i-molybdenum, nama-alloys azo zikhethwa ekushiseleleni izinsimbi ezinamandla kakhulu, izinsimbi ezingenasici, nezinye izinto ezinamaphoyinti ancibilika aphezulu.

2. Ukunakekela: Ukugcinwa okufanele kwama-electrode kubalulekile ukuze kuqinisekiswe ukusebenza kwawo nokuphila isikhathi eside.Nawa amathiphu okunakekela:

   a.Ukuhlanza Okuvamile: Khipha noma iyiphi imfucumfucu, i-weld spatter, noma ama-oxide endaweni ye-electrode ukuze ugcine ukuxhumana okuhle kukagesi.Sebenzisa amathuluzi okuhlanza afanelekile kanye nezincibilikisi njengoba kunconywe umenzi we-electrode.

   b.Ukugqoka kwe-Electrode: Ngezikhathi ezithile gqokisa amathiphu e-electrode ukuze ulondoloze ukwakheka kwawo kanye nekhwalithi yendawo.Le nqubo ihilela ukugaya noma ukulungisa ithiphu le-electrode ukususa noma yiziphi izindawo ezigugile noma ezilimele futhi ubuyisele i-geometry oyifunayo.

   c.Ukupholisa: Qinisekisa ukupholisa okufanele kwama-electrode ngesikhathi sokushisela, ikakhulukazi uma usebenzisa imisinga ephezulu noma ezinhlelweni zokushisela eziqhubekayo.Ukushisa okudlulele kungaholela ekonakaleni kwe-electrode nokuncipha kwekhwalithi yokushisela.

   d.I-Insulation: Vala abanikazi be-electrode futhi uqinisekise ukufakwa okufanele phakathi kwe-electrode nomshini wokushisela ukuvimbela ukuvuza kukagesi nokuthuthukisa ukuphepha.

   e.Ukuqapha: Hlola njalo ama-electrode ukuze uthole izimpawu zokuguga, ukonakala, noma ukonakala.Shintshanisa ama-electrode agugile noma alimele ngokushesha ukuze ugcine ikhwalithi yokushisela efanele.

Ukukhethwa kwezinto ze-electrode emishinini yokushisela indawo ye-inverter ephakathi nendawo kufanele kucabangele izici ezifana nezinto zokusebenza, izimo zokushisela, kanye nekhwalithi yokushisela oyifunayo.Izindlela zokunakekela ezifanele, ezihlanganisa ukuhlanza, ukugqokisa, ukupholisa, ukufaka ugesi, nokuqapha, kubalulekile ukuze kuqinisekiswe ukuphila isikhathi eside nokusebenza kwama-electrode.Ngokukhetha izinto ezifanele ze-electrode kanye nokusebenzisa izindlela zokulungisa ezisebenzayo, abashiseli bangakwazi ukufeza ukushisela okungaguquki nokusezingeni eliphezulu ezinhlelweni zokushisela ezihlukahlukene.
