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 ephezulu. 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 zokwenziwa kwe-electrode emishinini yokushisela indawo ye-inverter ye-medium-frequency kufanele kubhekwe izinto ezifana nezinto zokusebenza, izimo zokushisela, kanye nekhwalithi yokushisela oyifunayo. Izinqubo zokunakekela ezifanele, ezihlanganisa ukuhlanza, ukugqokisa, ukupholisa, ukuvaleka, 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.
