This comprehensive guide covers everything professionals and learners need to know about welding electrodes — from fundamental concepts to practical selection strategies. It explains the difference between consumable and non-consumable electrodes, breaks down the four major welding processes (SMAW, TIG, MIG, and SAW), and decodes electrode classification codes such as E6010, E6013, and E7018. The guide also outlines five key factors for choosing the right electrode — including base material, welding position, tensile strength, environment, and machine compatibility — along with a material-specific reference chart and a list of common selection mistakes to avoid. Published in February 2026, this resource is backed by D&H Sécheron's 60+ years of expertise in delivering high-performance welding consumables across steel, power, marine, and construction industries.

WHAT IS A WELDING ELECTRODE?
A welding electrode is a metal rod or wire that conducts electric current from the welding machine to the
workpiece — and may also act as a filler material that melts and joins two metals.
CONSUMABLE NON-CONSUMABLE
• Melts into the weld joint • Does NOT melt
• Used in SMAW, MIG, SAW • Transfers current & heat
• Provides filler material • Used in TIG welding
• Forms strong joints • Ideal for precision work
💡 Welding Rod vs. Electrode: A rod is filler material; an electrode always conducts current. Terms are often used interchangeably in stick welding.
TYPES OF WELDING ELECTRODES
B Y W E L D I N G P R O C E S S
SMAW TIG
Stick Welding TIG / GTAW
Most versatile & portable. Used for structural work, maintenance, Precision welding with tungsten electrodes. Ideal for stainless
and outdoor welding. steel & thin metals.
MIG SAW
MIG / GMAW Submerged Arc
Continuous wire feed for high productivity. Common in Heavy-duty industrial welding submerged under flux. Used in
automotive & fabrication. shipbuilding & pressure vessels.
