Description: The E7018 low hydrogen potassium type iron-carbon steel welding electrode is your go-to choice for exceptional versatility and performance. Its compatibility with both AC and DC ensures it can conquer all-position welding with ease. This remarkable electrode not only minimizes spatter but also offers effortless slag removal, resulting in flawless weld appearances every time. It truly shines in flat and fillet welding scenarios. What sets it apart is its superb mechanical properties and high deposition efficiency, courtesy of an iron-rich coating that reduces the layers needed in welding and boosts productivity. To ensure optimal performance, prepare the workpiece by removing rust, oil, and moisture. The electrode should be baked at approximately 350 ºC, guaranteeing it is perfectly dry and primed for immediate use.
Uses: Seamlessly crafted for crucial applications, this electrode excels in welding ships, boilers, pressure vessels, pipes, and other vital structural components made from the corresponding strength grade steel.
