Frequently Asked Questions
What is an E7018 welding electrode?
E7018 is a low-hydrogen, iron-powder covered stick electrode used for welding carbon and low-alloy steels where strong mechanical properties, crack resistance, and high-quality weld deposits are required.
What welding process is used with Harris E7018 electrodes?
These electrodes are designed for shielded metal arc welding (SMAW), commonly called stick welding.
Can Harris E7018 electrodes be used with AC?
Yes. Harris specifies these E7018 electrodes for operation with AC or DCEP welding current.
Can E7018 be welded in all positions?
Harris identifies E7018 for flat, horizontal, vertical-up, and overhead welding. Vertical-down welding is generally not recommended.
What amperage should I use for 3/32" E7018?
Harris recommends approximately 65–85 amps for flat welding and 50–80 amps for vertical or overhead welding. Actual settings may vary with joint design, welding machine, technique, and other application factors.
What amperage should I use for 1/8" E7018?
Harris recommends approximately 90–130 amps for flat welding and 85–120 amps for vertical or overhead welding.
What amperage should I use for 5/32" E7018?
Harris recommends approximately 130–180 amps for flat welding and 110–160 amps for vertical or overhead welding.
What is the difference between the 5 lb and 10 lb options?
The electrode classification and welding characteristics remain the same for a selected diameter. The package-size option determines whether you receive a 5 lb or 10 lb tube.
What applications are Harris E7018 electrodes commonly used for?
Typical applications include piping, pressure vessels, boilers, low-alloy structures, heavy-duty equipment, shipbuilding, general maintenance, and production fabrication.
Why is E7018 called a low-hydrogen electrode?
The electrode coating is formulated to limit hydrogen introduced into the weld deposit. Proper handling and storage are important to maintain the low-hydrogen characteristics of the electrode.
How should E7018 electrodes be stored?
Keep electrodes dry and follow Harris, applicable welding-code, and job-procedure requirements for storage and handling of low-hydrogen electrodes. Do not use electrodes that have been improperly stored without first determining whether they remain suitable for the intended work.
Does Harris E7018 meet AWS requirements?
Harris lists these electrodes as complying with ANSI/AWS A5.1 and ASME SFA 5.1 E7018 requirements.
