Stick Electrodes — Selection Guide

Stick welding (SMAW) has survived 100 years because the consumable is self-contained: filler metal, shielding gas (from the flux), and slag protection all wrapped around a steel core wire. No gas bottles, no wire feeders. Just a rod, a stinger, and a power source.

The AWS E-classification system packs critical info into 4 digits. A 7018 rod means: 70,000 PSI tensile strength, all-position capability (1), and a low-hydrogen iron powder coating suitable for AC/DCEP (8). Understanding this numbering system is the fastest way to pick the right rod for any job.

The five most common electrodes cover nearly all shop work. 6010 runs DCEP only and digs hard, making it the pipeline root pass standard. 6011 is the AC equivalent, built for buzz boxes and farm welding. 6013 is the beginner-friendly rod with a soft, quiet arc and easy slag removal. 7018 is the structural workhorse specified by AWS D1.1 for critical joints. 7024 is a drag rod for flat-position production work with high deposition rates.

Diameter selection follows material thickness and amperage. A 3/32 rod runs at 60-90 amps for thinner material and root passes. A 1/8 rod runs at 90-140 amps and handles the bulk of general fabrication. A 5/32 rod at 120-180 amps speeds up heavier plate work. Each manufacturer publishes recommended ranges, but these starting points get you close.

Storage matters, especially for low-hydrogen rods. 7018 absorbs moisture from the air, and wet 7018 causes hydrogen cracking, the kind of defect that doesn’t show up until the weld is under load. Keep opened cans in a rod oven set to 250-300F. Non-low-hydrogen rods like 6013 and 6011 are more forgiving but still perform better when stored dry.
