430Mpa Hand Electrode For Low Carbon Steel
Application & Standard
1. Suitable for welding of carbon steel and corresponding strength of boiler, pipeline, vehicle,
building, bridge and other structures, such as Q235.
2. The standard we met: GB/T5117 E4315, AWS, ISO2560-A:E 35 3 B 2 2, ISO 2560-B: E4315A
When welding carbon steel, the strength grade of the steel is typically chosen to match the electrode, taking into account the complex structure, thick plate, stiffness, dynamic load, and poor weldability. Low hydrogen type electrodes are typically chosen for their good plasticity, high impact toughness, and crack resistance. If the welding position requires a particular electrode, such as a bottom electrode, vertical downward electrode, or other special electrode, it must be utilized. The welding efficiency can be increased by using iron powder electrodes.
Features
1. Low sodium hydrogen electrode with a stable arc, lovely shape, tiny splash, and exquisite ripple.
2. Consistent mechanical characteristics, strong plasticity, impact resistance, and crack resistance.
The minimum tensile strength of molten metal is 42Kg/mm2 (420MPa) for GEM-47 type low carbon steel with hand electrode, and 7 indicates low sodium hydrogen type electrode coating, appropriate for full position welding. It is a carbon steel electrode coated with low sodium hydrogen. It may be welded in any position and runs on a DC power supply. More significant carbon steel and low alloy steel are primarily welded together.
