Frequently Asked Questions
E7018 is a low-hydrogen electrode with iron powder in the coating, providing higher strength, better X-ray quality, and faster deposition rates compared to standard rods like E6013.
Yes, the E7018 electrode is designed for all-position welding, including flat (PA), horizontal (PB), vertical (PC/PD), and overhead (PE/PF) positions.
Our E7018 electrodes are versatile and compatible with both AC (Alternating Current) and DC (Direct Current) welding machines.
Absolutely. Due to its low-hydrogen properties and Level I X-ray flaw detection performance, it is highly recommended for pressure vessels and shipbuilding.
The iron powder increases the deposition efficiency, meaning you can fill joints faster with fewer passes, reducing overall labor and material time.
We provide a comprehensive range including ER70S-6, E6013, E6010, E6011, as well as stainless steel, aluminum, and flux-cored welding wires.
