Description: Introducing the revolutionary E7018 welding electrode, a low hydrogen potassium iron-carbon steel marvel. With its seamless compatibility with both AC and DC currents, it becomes the epitome of flexibility, perfect for mastering all-position welding. This innovative electrode minimizes spatter, simplifies slag removal, and guarantees a pristine weld finish, particularly thriving in both flat and fillet welding scenarios. Packed with superior mechanical properties, it also offers an impressive deposition efficiency, courtesy of its iron-enriched coating. This advancement means fewer welding layers are needed, drastically boosting productivity. Before embarking on your welding journey, ensure the workpiece is impeccably clean from rust, oil, and moisture. Prepare the electrode diligently by baking it at approximately 350 ºC, ensuring it is optimally dry for immediate, flawless application.
Uses: Crafted with precision for essential and demanding applications, our electrode is the ultimate choice for welding ships, boilers, pressure vessels, pipelines, and other critical structural elements made from the respective strength grade steel.
