When you are welding up a crane boom, repairing an excavator bucket, or fabricating structural steel that needs to hold serious weight, a standard 7018 rod just won't cut it. You need the extra muscle of the Hobart Hoballoy 9018-M. This 5/32" stick electrode is built for high-strength steel, delivering a massive 90,000 psi tensile strength to match the base metal of heavy equipment and critical structures.
Hobart knows that high-strength welding can be tricky, which is why they designed this rod to run smoothly. The low hydrogen iron powder coating gives you a stable, forgiving arc that digs in deep but leaves a bead that looks great. If you are used to running 7018, you will feel right at home with the 9018-M, but you will be laying down metal that is significantly stronger and tougher. The slag peels off easily, so you aren't spending half your day chipping and grinding, letting you move on to the next pass faster.
One of the biggest enemies of high-strength welds is cracking, often caused by moisture. Hobart ships these rods in a 50 lb hermetically sealed can to keep them bone dry until you crack the seal. The 'M' rating means it meets strict military specs for moisture resistance and toughness, so you know it can handle the cold and the stress without failing. Whether you are in the shop or out in the field, this is the rod you want in your stinger when the specs call for 90ksi filler metal.
This 5/32" size is a workhorse for filling joints on thick plate. While it runs best on DCEP, it offers good puddle control in various positions if you have the skill. Don't risk a weld failure on critical machinery—upgrade to the Hobart Hoballoy 9018-M and weld with confidence knowing your deposit can take the abuse.
