What type stainless There are basic coated stainless steel electrode and Aluminum Flux Core Welding Wire acidic drug skin two categories. Basic coated stainless steel electrode with a type of stomatal sensitivity to small , stable alloy composition Fixed and excellent mechanical properties and welding performance characteristics ; acidic Drug skin type stainless steel electrode with drug-resistant skin redness and excellent mechanical properties and welding performance. ( 1 ) stainless steel electrode model based GB/T983-1995 " stainless steel electrode " requirement , stainless steel electrodes deposited metal model based on the chemicalChemical composition , drug skin type , welding position and the welding current category from Points. Its model preparation method is: the first letter "E" indicates electrode , "E" behind the numbers indicate the chemical composition of deposited metal classification code , such asThere are special requirements for chemical composition, the chemical composition of elemental symbol table Shown , on the back of digital ; dash " - " followed by two numbers indicate the drug skin type , welding position and the welding current category.
