Description: Discover the unparalleled performance of the E7018 low hydrogen potassium type iron-carbon steel welding electrode. Renowned for its remarkable versatility, it seamlessly adapts to both AC and DC currents, excelling in all-position welding. Experience welding like never before with minimal spatter, easy slag removal, and a flawless weld finish, particularly excelling in flat and fillet welding. Its iron-rich coating ensures top-tier mechanical properties and high deposition efficiency, reducing welding layers and enhancing productivity substantially. Before welding, ensure the workpiece is meticulously free of rust, oil, and moisture. Prepare the electrode by baking at approximately 350 ºC, guaranteeing it is optimally dry and ready for immediate, efficient use.
Uses: Crafted with precision for the most critical applications, this electrode is the ultimate choice for welding ships, boilers, pressure vessels, pipes, and other vital structural components constructed from steel of equivalent strength grade.
