Electrodos de varilla de acero dulce Lincoln

Inweld 7018 is a general-purpose, all-position stick welding electrode for carbon steel, free-machining steel, high-tensile steel and low-alloy steel. Its low-hydrogen iron-powder coating delivers a quiet, steady arc with low spatter and medium penetration.

Features and applications

• High deposition efficiency with a smooth, finely rippled weld bead and easy slag removal.
• Suitable for structural fabrication, including beams, angles, channels and plates.
• Additional applications include cast steel, process piping, cold-rolled steel and shipbuilding steel.

Technical specifications

• Classification: AWS A5.1 E7018.
• Process: SMAW (stick welding).
• Recommended polarity: DCEP (electrode positive).
• AWS tensile strength specification: 70,000 psi.
• AWS yield strength specification: 58,000 psi.
• AWS elongation specification: 22%.
