Description: Discover the unparalleled versatility of the E7018 low hydrogen potassium type iron-carbon steel welding electrode, renowned for its adaptability with both AC and DC currents. This stellar electrode excels in all-position welding, ensuring minimal spatter and easy slag removal while delivering an immaculate weld appearance, especially in flat and fillet welding. Revel in its superior mechanical properties, complemented by a high deposition efficiency due to its iron-rich coating. This innovation reduces the welding layers required, boosting productivity. Prior to welding, it is crucial to have the workpiece devoid of rust, oil, and moisture. Electrode preparation is essential, achieved by baking at about 350 ºC, ensuring it is impeccably dry and primed for immediate use.
Uses: Meticulously crafted for high-stakes applications, this electrode is the epitome of reliability, ideally suited for welding ships, boilers, pressure vessels, pipelines, and other critical structural components fabricated from the corresponding strength grade steel.
