Typical Welding Parameters

Note: The amperage range is a typical starting range. Actual settings should be adjusted according to welding position, material thickness, joint design, power source, and approved welding procedure.

Typical Mechanical Properties

Common Applications

• Structural steel welding
• Mild and carbon steel fabrication
• Low-alloy steel welding
• Heavy equipment repair
• Industrial fabrication
• Maintenance and repair
• Shop and field welding
• Applications requiring low-hydrogen electrodes

Low-Hydrogen Performance

One of the main advantages of E7018 is its low-hydrogen coating. Controlling hydrogen is important in applications where hydrogen-related cracking is a concern, particularly when welding thicker, higher-strength, or more highly restrained steel components.

Proper electrode storage and handling are critical to maintaining the low-hydrogen characteristics of E7018.

Storage & Handling

Keep E7018 electrodes dry. Moisture absorbed by the electrode coating can reduce its low-hydrogen performance.

• Keep unopened packages protected from moisture.
• Store opened electrodes according to the applicable welding procedure and electrode manufacturer's recommendations.
• Use an appropriate welding rod oven when required.
• Avoid leaving electrodes exposed to humid shop or field conditions for extended periods.

Storage Tip: If your welding procedure requires controlled low-hydrogen electrodes, follow the specified storage, exposure, and reconditioning requirements for the job.

Frequently Asked Questions

What size are these E7018 electrodes?
This listing is specifically for 1/8" (3.2mm) diameter x 14" long E7018 electrodes.

What is E7018 commonly used for?
E7018 is commonly used for structural steel, carbon steel, low-alloy steel, industrial fabrication, maintenance, and applications requiring strong low-hydrogen weld deposits.

What does the 70 in E7018 mean?
The "70" indicates a minimum tensile strength of 70,000 psi for the deposited weld metal under the applicable classification requirements.

Is E7018 an all-position electrode?
Yes. The "1" in E7018 identifies it as an all-position electrode.

Can I run E7018 on AC?
Yes. E7018 can be operated on AC or DCEP (DC+).

What amperage should I use for 1/8" E7018?
A typical starting range is approximately 90–150 amps. Actual amperage depends on the welding position, material, joint design, equipment, and procedure.

Why does E7018 need to be kept dry?
The electrode uses a low-hydrogen coating. Excess moisture can increase hydrogen introduced into the weld and reduce the benefits of the low-hydrogen electrode system.

How are these electrodes sold?
They are priced per pound and sold in complete 5 lb packs.

Can I buy only one pound?
No. The minimum purchase for this listing is one complete 5 lb pack.
