Description: Discover unparalleled versatility with the E7018 low hydrogen potassium type iron-carbon steel welding electrode by JIANGSU JIUZHOU NEW MATERIAL TECHNOLOGY CO., LTD. This exceptional electrode is designed to seamlessly accommodate both AC and DC power sources, making all-position welding effortlessly achievable. Revel in minimal spatter and the ease of slag removal, while enjoying an immaculate weld appearance, especially in flat and fillet welding scenarios. Its remarkable mechanical properties and high deposition efficiency are credited to its iron-rich coating, which significantly reduces the number of necessary welding layers, boosting productivity to new heights. Before welding, ensure that your workpiece is scrupulously clean of rust, oil, and moisture. Prepare the electrode with precision by baking it at an ideal temperature of 350 ºC, thereby ensuring it emerges dry and ready for immediate, efficient use.
Uses: Expertly crafted for the most demanding and critical applications, this premium electrode shines in welding ships, boilers, pressure vessels, pipes, and other vital structural components constructed from steel of the corresponding strength grade.
