S126032-035 - Hobart E11018-M Low Alloy Stick Electrode 3/32 Inch

Weld High-Strength Steel with Confidence

When the job calls for welding heavy-duty armor plate, crane booms, or T-1 structural steel, a standard 7018 rod just won't cut it. You need a consumable that matches the strength of your base metal. Enter the Hobart Hoballoy 11018-M. This 3/32-inch stick electrode is the heavy hitter of the Hobart lineup, delivering over 100,000 psi of tensile strength to ensure your welds hold up under extreme stress. It’s the go-to rod for professional welders working on heavy equipment repairs, mining machinery, and military-grade projects.

One of the first things you'll notice about the Hoballoy 11018-M is how smoothly it runs. Hobart has formulated this rod to have excellent puddle control, which is crucial when you are trying to manage heat input on sensitive quenched and tempered steels. The arc is soft yet penetrating, and the wetting action at the toes is superb, helping you avoid undercut that could lead to failure down the road. Plus, the slag lifts off easily—often curling up on its own—so you spend less time chipping and more time burning rods.

Why Choose 11018-M?

If you are repairing a cracked excavator boom or fabricating a high-stress joint on a trailer frame, using an under-matched rod like a 7018 can lead to catastrophic weld failure because the weld metal will yield before the steel does. The 11018-M matches the mechanical properties of steels like HY-80 and T-1, ensuring the joint is as strong as the plate surrounding it. The "Low Hydrogen" designation means it resists moisture pickup, protecting your welds from delayed cracking, which is the enemy of high-strength steel fabrication.

Practical Tips for Success:

• Storage: Keep these rods in a holding oven once the can is opened. Moisture is the enemy of 11018 rods.
• Preheat: Always check the preheat requirements for the specific grade of steel you are welding. High-strength steels often require preheat to prevent cracking.
• Technique: Use a short arc length to protect the puddle from the atmosphere. The 3/32" diameter is great for root passes or vertical-up welding where you need precise control.
