Description: The exceptional E7018 low hydrogen potassium type iron-carbon steel welding electrode redefines adaptability with its dual compatibility for AC and DC currents. This remarkable electrode is expertly designed for all-position welding, offering you the advantage of significantly reduced spatter, seamless slag removal, and a flawless weld finish. It particularly excels in flat and fillet welding operations. The electrode is enriched with iron, leading to superior mechanical properties and increased deposition efficiency. This results in fewer welding layers needed, thereby boosting productivity. Before commencing welding, it is crucial to prepare the workpiece by removing any rust, oil, or moisture. Additionally, for optimal electrode performance, bake it at approximately 350 ºC, ensuring it remains dry and primed for immediate application.
Uses: Ingeniously crafted for high-stakes applications, this electrode is the perfect choice for welding ships, boilers, pressure vessels, pipes, and other pivotal structural elements fabricated from steel of equivalent strength grade, ensuring reliable performance across projects.
