Application&Standard&Note

1. Suitable FOR WELDING OF CARBON STEEL AND LOW ALLOY STEEL, AS WELL AS THE CORRESPONDING STRENGTH OF BOILER, pipeline, vehicle, BUILDING, BRIDGE AND other STRUCTURES, SUCH AS Q345.
2. The standard we met: GB/T5117 E5018, AWS A5.1 E7018 & A5.1M E4918, ISO2560-A:E 42 3 B 3 2, ISO 2560-B: E4918 A

Since the E7018 electrode easily absorbs moisture, it is kept in the electrode drying oven. The electrode stored in the air can be rebaked at 350 ~ 400℃ for 1h ~ 2h. In order to restore the properties of the skin. Mild steel can be welded with unbaked E7018 electrodes, but the final weld strength may not be high enough.

Features

Iron powder low hydrogen type hand electrode, high welding efficiency, stable arc, beautiful forming, corrugations, little splash, easy de-slagging, good drug skin fire resistance, good stomatal resistance. Stable mechanical properties, good plasticity and low temperature impact tenacity.

E7018 is a high quality carbon steel electrode with iron powder low hydrogen potassium coating. The electrode has excellent welding process performance, arc stiffness is good, not easy to produce magnetic bias blowing, welding seam forming fine clean and beautiful, less splash, slag is easy; The weld metal has excellent and stable low temperature toughness and crack resistance. Ac and DC dual use, can carry on the whole position welding. Its characteristic is that the drug skin contains iron powder, which can reduce the number of welding layers. Bake the electrode at 350 ~ 400 degrees Celsius for 1 ~ 2 hours, and use with baking. Generally this high quality electrode is used for welding ship steel (A, B, D or E, A36, E36) and important structures of low-alloy steel of the same grade of strength, such as boilers, pressure vessels and offshore drilling platforms, etc.
