The 5P welding rod—also labeled E6010—is a versatile filler metal designed for direct current (DC) welding, especially ideal for pipe work.
5P rods generate a steady, stable arc that delivers deep penetration with minimal spatter. They perform reliably on painted, greasy, and rusty steel, and are suitable for flat, overhead, and vertical welding positions. The filler metal spreads smoothly and cures quickly, reducing post‑weld cleanup.
Coated with a high‑cellulose sodium compound, 5P rods are compatible with 220–440 V DC welding machines. According to Richard Finch’s Welder’s Handbook, they are available in diameters of 1/8 inch and larger.
These rods excel in welding pipes, storage tanks, and structural joints in buildings, bridges, and maritime vessels. They boast a tensile strength of 70,000 psi, as reported by AMFiller.com.
