Hardfacing Welding Electrode
Chiyero: DIN 8555 (E6-UM-60)
Rudzi rweNhamba: TY-C DUR 600
Tsanangudzo & Mashandisirwo:
· Yekutanga yakavharwa SMAW electrode yekuomesera kumberi.
· Yakanakisa kupikisa kupokana nekumanikidza kumanikidza uye zvinokanganisa.
· Yese inoshanda pakupfekedzwa pazvikamu zvesimbi, simbi yakakandwa uye yakakwira Mn-simbi, inozviisa panguva imwe chete kune abrasion, kukanganisa uye kudzvanywa.Mamiriro ekushandisa akajairika ivhu rinofamba uye indasitiri yekurapa matombo, semuenzaniso mazino ekuchera, mapanga emabhakiti, shaya dzekupwanya nemakoni, sando dzechigayo nezvimwe.
Kemikari yakagadzirwa nesimbi yakaiswa (%):

General Characteristics:
· Microstructure Martensitic
· Machinability Yakanaka neTungsten carbides tipped maturusi
· Preheating Preheat zvinorema zvikamu uye yakakwirira-tensile simbi kusvika 200-350 ℃
· Redrying Redry ye2 h pa300 ℃ usati washandisa.
