HYW E7018 Stick Electrodes are a low-hydrogen, iron-powder rod engineered for high-strength, crack-resistant structural welds, supplied in a convenient 10 lb package. They run smoothly on AC or DC+ and deposit dense, ductile 70,000 psi weld metal that meets demanding code and radiographic requirements — the go-to choice for structural steel, pressure work, and high-restraint joints.

Storage & Handling
As a low-hydrogen electrode, E7018 must be kept dry to perform as designed. Store opened electrodes in a heated rod oven, and redry in accordance with AWS/manufacturer guidelines if they are exposed to moisture, to preserve low-hydrogen weld quality.
Recommended amperage ranges are general guidelines; optimal settings vary with base-metal thickness, joint design, and welding position.
