Description: Dive into the world of precision welding with the outstanding E7018 low hydrogen potassium type iron-carbon steel welding electrode from JIANGSU JIUZHOU NEW MATERIAL TECHNOLOGY CO., LTD. This premium electrode offers unparalleled versatility, seamlessly working with both AC and DC power sources, and is a maestro of all-position welding. It guarantees minimal spatter, makes slag removal a breeze, and delivers a flawless weld appearance, especially shining in flat and fillet welding scenarios. Its mechanical properties are top-notch, and it boasts a high deposition efficiency, courtesy of its iron-rich coating that minimizes the need for multiple welding layers, thereby optimizing productivity. Before you begin welding, ensure your workpiece is immaculate, free of rust, oil, and moisture. Prepare the electrode by baking it to perfection at approximately 350 ºC, ensuring it is perfectly dry and ready for immediate action.
Uses: Specifically engineered for the most demanding applications, this electrode is your go-to choice for welding ships, boilers, pressure vessels, pipes, and other critical structural elements made from steel of the corresponding strength grade.
