OVERVIEW

Reliable Stick Rod for Chrome-Moly Pipe and Plate

For professional welders tackling high-temperature alloy jobs, the Exocor E8018-B2 3/16" electrode offers the perfect blend of runability and metallurgical performance. When you are welding chrome-moly pipe or repairing boiler tubes, you need a rod that burns smooth, doesn't stick, and lays down a bead that passes X-ray inspection every time. This electrode is designed to do just that, providing a stable arc with minimal spatter, allowing you to focus on your puddle control and travel speed without fighting the rod.

The 3/16-inch diameter is ideal for filling heavy joints efficiently. While smaller rods are used for root passes, this larger diameter allows for higher deposition rates on fill and cap passes, speeding up production on thick-walled pressure vessels and heavy structural components. The flux coating is engineered to be moisture-resistant, but the real game-changer is the packaging. Coming in a 50lb hermetically sealed can, these rods are protected from humidity right up until you crack the seal. This means you get fresh, dry rods that run consistently from the first burn to the last, minimizing the risk of porosity and hydrogen cracking that can plague low-alloy welding.

Welders will appreciate the slag release on this E8018-B2. In deep grooves, stubborn slag can be a nightmare, leading to inclusions and rework. This Exocor rod features a slag system that cools quickly and detaches easily, often curling up on its own, which saves time on inter-pass cleaning. Whether you are running DCEP or AC, the arc start is crisp, and re-strikes are manageable, reducing the chance of starting porosity. The puddle fluidity is optimized to wet out smoothly at the toes, reducing the need for grinding to blend the weld into the base metal.

This rod is specifically meant for 1-1/4 Cr - 1/2 Mo steels, common in power plants and refineries. Using the correct filler metal is critical in these applications to match the base metal's heat resistance. With the Exocor E8018-B2, you aren't just laying down metal; you are restoring the full mechanical properties of the assembly. It handles the heat, literally and figuratively, giving you the confidence that your welds will hold up under the extreme service conditions of steam lines and process piping.

FAQ

E8018-B2 electrodes are primarily used for welding 1.25% Chromium and 0.5% Molybdenum steels found in high-temperature service applications like power plants and refineries.

Yes, as a low-hydrogen electrode, it should be stored in a holding oven after opening the hermetically sealed can to prevent moisture pickup.

The weld deposit typically has a minimum tensile strength of 80,000 psi (550 MPa) as per AWS requirements.

While it can physically weld mild steel, it is not recommended due to higher cost and the potential for cracking if the alloy content causes hardening in the mild steel dilution.

This electrode runs best on Direct Current Electrode Positive (DCEP), but can also be used with Alternating Current (AC).

The hermetic seal prevents atmospheric moisture from entering the coating, ensuring the rods remain low-hydrogen and ready to use without immediate rebaking.

3/16" is generally considered too large for vertical welding; it is best suited for flat and horizontal fill passes on thick materials.
