Description: Introducing the unparalleled E7018 low hydrogen potassium type iron-carbon steel welding electrode, a marvel of welding technology. Its extraordinary flexibility with both AC and DC currents makes it a leader in all-position welding. This electrode shines with minimal spatter and smooth slag removal, delivering a perfect weld finish, particularly in flat and fillet welds. With outstanding mechanical strength and high deposition efficiency, attributed to its iron-rich coating, it significantly reduces the number of welding layers required, boosting productivity. Before welding, ensure the surface is devoid of rust, oil, and moisture. Prepare the electrode by baking it at a precise temperature of around 350 ºC, ensuring it achieves a dry state for optimal performance.
Uses: Crafted for supreme performance in critical scenarios, this electrode is the go-to choice for welding ships, boilers, pressure vessels, pipes, and other essential structural components made from steel of corresponding strength grades.
