E7018 rods are a type of welding rod used in arc welding processes. They’re made with low-hydrogen, high-tensile iron powder electrodes and are particularly good at penetrating the base metal they’re working on. Because E7018 rods produce a slower heating action than other types, they can be used on thicker materials and provide excellent load-bearing strength. There’s no other welding rod that has such strong welds. This makes them perfect for modern construction and industrial applications requiring strength and penetration depth to produce durable, dependable welds.
Advantages of E7018 Rods
Several advantages are worth noting when using an E7018 rod for welding cast iron to mild steel. Firstly, these rods have excellent arc stability allowing them to maintain their shape even when used in down-hand positions. Secondly, they produce smooth bead profiles that minimize grinding during post-weld cleanup operations. Finally, they can withstand higher levels of corrosion than other electrodes due to their high chromium content. This makes them perfect for outdoor applications where corrosion could be a problem.
Welding Rod Uses
When using an E7018 rod, you must prepare your metals properly before beginning the welding process. Ensure that both pieces are clean and free of debris or contamination that could affect the integrity of the welded joint. Use a wire brush or grinder to prepare each piece before starting your welds for the best results. Once your materials are prepped and ready to go, you can begin by striking an arc in the joint until full penetration is achieved, then build up multiple passes until the desired thickness is reached.
We recommend using alternating current (AC) power sources when working with E7018 rods since they require higher winds than other electrodes. AC power sources provide more current at lower voltages which helps prevent burn-through during deep penetration applications like those found in cast iron work pieces.
Conclusion :
E7018 electrodes are a type of welding rod used to weld low-carbon steel. They can be used in all positions but work best on flat and horizontal surfaces. E7018 rods produce minimal smoke and spatter, which makes them ideal for use in tight spaces or indoors. It is essential to keep the electrode angle at 15 degrees or less when using these rods to prevent slag inclusion. Thanks for reading!
