Hardfacing WeldingI-Electrode
Umgangatho: DIN 8555 (E7-UM-250-KPR)
Uhlobo lweNombolo: TY-C BMC
Inkcazo kunye nesicelo:
· I-electrode ye-SMAW yokubuyisela isiseko esiphezulu
· Isakhiwo esipheleleyo se-austenite.Ukusebenza okuphezulu kakhulu kunye nobunzima obuphezulu.
• Ilungele ukugquma kwiindawo eziphantsi koxinzelelo oluphezulu kunye nokothuka xa kudityaniswa ne-abrasion.Ukubekwa phezulu kungenziwa kwintsimbi ye-ferritic kunye ne-austenitic eqinile ye-Mn-steel kunye ne-joints of hard Mn-steel inokudityaniswa.
· Iindawo ezisetyenziswayo eziphambili zikushishino lwemigodi kunye nesamente, umzila kaloliwe onqumlayo, iimpompo ze-dredge, iipiston zokucinezela ngoxinzelelo lwehydraulic, indawo yesityuli ephantsi kweempembelelo eziphezulu zezimbiwa ezithambileyo.
