CLASSIFICATIONS:
E7018-1 H4R

IronArc 7018-1 MR (3/32x14 in, 50 lb can) is a mild steel, low hydrogen stick electrode ideal for pipeline and pipe repair welding. Meets AWS A5.1 E7018-1 H4R.

DETAILS

Lincoln Electric’s IronArc 7018-1 MR produces a soft, smooth and stable arc that offers an easy to manipulate weld puddle and good operator control, even for beginner welders! Compared to its Excalibur equivalent that is known for its deeper penetration profile, the IronArc 7018-1 is designed with a flat bead profile that has excellent wetting in the toes ideal for cap passes. By combining a high deposition rate, tested moisture resistance, and low spatter levels, these stick electrodes minimize post-weld clean up and allow for less hold times to optimize productivity.

Features

Soft arc for ease of puddle manipulation
Smooth arc transfer
Excellent wetting in the toes allowing for less hold times
Flat bead profile ideal for cap passes on pipe, groove welds, and pipe repair
No intentional addition of zinc for moisture resistance
Q2 Lot®- Certificate showing actual deposit chemistry and mechanical properties available online
