OVERVIEW

High-Performance Manganese-Molybdenum Welding Electrodes

The Hobart Hoballoy 10018-D2 is a premium low-alloy steel electrode designed for the welding of high-tensile steels where weld metal strength must equal or exceed 100,000 psi. Engineered to meet the rigorous AWS A5.5 specifications, this E10018-D2 classified electrode features a specialized manganese-molybdenum alloy core and a low-hydrogen iron powder coating. This composition ensures exceptional mechanical properties, making it the preferred choice for industrial fabrication sectors requiring superior structural integrity and resistance to cold cracking.

Industrial procurement specialists will appreciate the consistent quality and traceability associated with the Hobart brand. The 3/16-inch diameter is optimized for heavy deposition rates in flat and horizontal positions, significantly improving productivity on thick-section materials. The electrode formulation provides a stable arc and excellent puddle control, resulting in X-ray quality welds essential for critical infrastructure projects. The inclusion of manganese and molybdenum enhances the weld deposit's hardenability and impact toughness, even at sub-zero temperatures, which is a critical requirement for pressure vessel and piping applications.

Moisture control is paramount in high-strength welding to prevent hydrogen-induced cracking (HIC). The Hoballoy 10018-D2 is packaged in a hermetically sealed 50-pound can, ensuring the coating remains dry and factory-fresh until the moment of use. This packaging solution reduces waste and the immediate need for re-baking upon opening, provided standard exposure limits are observed. For MRO operations dealing with earthmoving equipment, crane booms, or high-stress structural components, this electrode offers the reliability and mechanical performance necessary to meet stringent engineering codes.

FAQ

E10018-D2 electrodes are designed for welding high-tensile strength steels, specifically manganese-molybdenum alloys, often found in pressure vessels, heavy construction equipment, and structural components requiring at least 100,000 psi tensile strength.

The recommended polarity for Hobart Hoballoy 10018-D2 is Direct Current Electrode Positive (DCEP), also known as DC+ or reverse polarity.

Yes, as low-hydrogen electrodes, they should be stored in a holding oven at temperatures between 250°F and 300°F (120°C - 150°C) after opening the hermetically sealed can to prevent moisture absorption and hydrogen cracking.

While E10018-D2 is an all-position classification, the 3/16-inch diameter is generally too large for vertical or overhead welding due to the large weld puddle. It is best suited for flat and horizontal fillet welds.

The main difference is tensile strength and alloy composition. E7018 has a minimum tensile strength of 70,000 psi for mild steel, while E10018-D2 has a minimum of 100,000 psi and contains manganese and molybdenum for welding higher strength alloy steels.

The typical operating amperage range for a 3/16-inch diameter E10018-D2 electrode is approximately 200 to 275 Amps.

E10018-D2 is often used in applications requiring specific hardness controls, but suitability for NACE/sour gas service depends on the specific heat input and post-weld heat treatment procedures used to maintain hardness below required limits.
