Description: The Heavy-Duty E7018 Welding Electrode, a masterpiece of engineering from JIANGSU JIUZHOU NEW MATERIAL TECHNOLOGY CO., LTD., offers unparalleled adaptability. With its low hydrogen potassium type iron-carbon steel composition, it smoothly transitions between AC and DC power sources, excelling in all-position welding tasks. This electrode minimizes spatter and makes slag removal a breeze, delivering a flawless weld appearance. Especially proficient in flat and fillet welding, it provides excellent mechanical properties and boasts a high deposition efficiency. Its iron-rich coating reduces the number of welding layers required, boosting productivity significantly. For optimal performance, ensure the workpiece is devoid of rust, oil, and moisture. Prior to welding, bake the electrode at approximately 350 ºC, ensuring a dry and ready state for immediate use.
Uses: This electrode, crafted with precision for critical applications, is perfectly suited for constructing ships, boilers, pressure vessels, pipes, and other vital structural components that require the corresponding strength grade steel.
