ER385 Tšepe e sa Khaotseng ho Welding Rod
Tlhaloso e Khutšoanyane:
ER385 ke mofuta oa tšepe e tlatsang ho tjheseletsa, haholo-holo elektrode ea tšepe e sa ruseng. “ER” e emetse “Electrode kapa Rod,” 'me “385″ e bontša sebopeho sa lik'hemik'hale le litšobotsi tsa tšepe e tlatsang. Tabeng ena, ER385 e etselitsoe ho tjheseletsa litšepe tse sa ruseng tsa austenitic.
ER385 Thupa ea ho Welding:
Litšepe tse sa hloekang tsa Austenitic, tse kang Type 904L, li na le maemo a holimo a chromium, nickel, le molybdenum, e leng se etsang hore li se ke tsa bola haholo 'me li lokele ho sebelisoa libakeng tse thata. Lithupa tsa ho welding tsa ER385 li sebelisoa hangata lits'ebetsong moo ho hanyetsa mafome e leng ntlha ea bohlokoa, joalo ka indastering ea lik'hemik'hale, petrochemical le ea likepe. Lithupa tsa ho welding tsa ER385 li loketse lits'ebetso tse fapaneng tsa ho welding, ho kenyeletsoa ho welding ea tšepe e sirelelitsoeng (SMAW), ho welding ea arc ea gas tungsten (GTAW kapa TIG), le ho welding ea arc ea tšepe ea gas (GMAW kapa MIG).
