Stainless Steel Welding Electrodes for welding repair and surfacing including structural steel welding rod, heat-resistant steel electrode, stainless steel electrode, welding electrodes, cast iron welding rod, nickel and nickel alloy electrode and special purpose welding rod, etc..

    The electrode model based electrode based national standards, to reflect the the electrode main characteristics of a representation. Electrode models include the following meanings: Electrode category electrode characteristics (such as welding core metal type, the use of temperature and chemical composition of the deposited metal or tensile strength), the drug skin type and the welding power source. Model representation of the different types of rods are also different.

1, carbon steel welding rod Model

    According to the requirements of the GB/T5117-95 "carbon steel electrode standard, carbon steel welding rod model based on the mechanical properties of the deposited metal, the drug skin type, welding position, and types of welding current division. The first letter "E" electrode; first two digits indicate the minimum tensile strength of the metal, deposited in kgf / mm 2 (1kgf/mm 2 = 9.81MPa); the third digit welding position, 0 "and" 1 "for all-position welding (can Ping, Li Yang, cross welding)," 2 "for flat welding and fillet welding," 4 "is suitable for vertical down welding; Third The fourth digit combination indicates the type of welding current and medicated skin type. Additional letters after the fourth digit electrodes with special provisions, such as "R" means resistance to moisture absorption electrode; additional "-1", said the impact properties of the special provisions of the welding rod.

2, low-alloy steel electrodes Model

    Standard provisions GB/T5118-95 "low-alloy steel electrodes, low alloy steel welding rod model based on the mechanical properties of the deposited metal, chemical composition, the drug skin types, welding position and current types of. The first letter "E" indicates the electrode, the first two digits of deposited metal minimum tensile strength; the third digit welding position "0" and "1" for all-position welding (flat welding, vertical welding overhead welding and cross welding), "2" for flat welding and fillet welding; third, fourth digit combination indicates the type of welding current and medicated skin type; suffix letters for the classification code of the deposited metal chemical composition and dash "-" previous figures separately. If there are additional chemical components, additional chemical components are directly represented by element symbols, and a dash "-" and separate from the front of a suffix letter.

3, stainless steel welding rod Model

    According to standard requirements GB/T983-95 "stainless steel electrode, stainless steel electrode according to the chemical composition of the deposited metal the drug skin types, welding position and the welding current types of models. The first letter "E" stands electrode "E" behind the numbers indicate the chemical composition of the deposited metal classification code, there are special requirements for the chemical composition of the element symbols placed behind the numbers. Dash "-" behind the two figures represents the type of Nickel Electrode coating, welding position, and types of welding current.
   Stainless steel electrode Model appended suffix (15,16,17,25,26) electrode the drug skin types and types of welding power supply, see table 1 - 1. Suffix 15 indicates alkaline, anti-DC-level resistance welding; suffix 16 alkaline or titanium or titanium calcium type, AC and DC; suffix 17 drug skin type 16 variant, said titanate type coating (SiO2 instead of the drug skin types 16 TiO2), welding melting rate, excellent anti-redness, AC and DC. Suffix 25 and 26 drug skin components and operating characteristics similar to the electrode and the drug skin types 15 and 16, the drug skin types 15 and 16, a description of the wire is also suitable for the drug skin types 25 and 26.
