Victory Welding Alloys 7018–3/16″ (STARTECHWELD)
Product is a low-hydrogen, all-position electrode designed for carbon steel, high-tensile steel, low alloy steel, and free-machining steels. It delivers a quiet steady arc, low spatter, and strong re-striking capabilities. The coating supports high deposition efficiency and x-ray quality weld deposits with excellent Charpy impact values at sub-zero temperatures (78 ft-lbs at -20°F).
Best for: Professional welders and fabrication shops needing reliable, all-position performance on carbon and alloy steels with excellent low-temperature toughness.
Limitations: Requires proper storage and handling to maintain low-hydrogen properties; slag removal is needed to reveal the final bead.
Hy-weld 7018 1/8″ Premium Arc Electrodes
Contains multiple 1/8″ electrodes conforming to AWS A 5.1 E7018 (ASME/SFA-A5.1). Suitable for welding hardenable and cold-rolled steels, including those with higher sulfur or selenium content. The 1/8″ size balances ease of use with adequate penetration for mid-thickness work.
Best for: Welders working with hardenable steels or thickened sections where dependable 7018 performance is needed from a compact-size rod set.
Caution: Improper amperage settings can affect arc stability and bead appearance; ensure the power source supports E7018 requirements.
Victory Welding Alloys 7018–1/8″ STARTECHWELD
Low-hydrogen, all-position electrode for carbon steel, high-tensile steel, low alloy steel, and free-machining steels. Features quiet steady arc, low spatter, and excellent re-striking. Slag removal reveals a finely rippled bead and robust Charpy impact values at sub-zero temperatures.
Best for: Projects requiring a stable arc with clean bead profiles and strong impact performance in cold environments.
Limitation: 1/8″ diameter may be too small for very high deposition needs without appropriate setup.
Victory Welding 7018 5/32″ STARTECHWELD
5/32″ diameter electrodes with low-hydrogen coating designed for all-position use on carbon and alloy steels. Embeds with steady arc, low spatter, and high deposition. Bead appearance is rippled and accumulates robust weld deposits suitable for structural work.
Best for: Thicker sections or higher deposition requirements where larger diameter rods provide faster fill and strong welds.
Caution: Requires compatible power settings and proper technique to avoid excessive heat input or distortion.
TASKZOOM E7018 3/32″ 5LB
3/32″ diameter electrodes with low-hydrogen coating for all-position welding on carbon steel. Offers a stable arc, smooth starts, easy re-striking, and minimal spatter. Suitable for thin-to-medium carbon steel projects and repairs.
Best for: DIYers and professionals working on lighter gauge steel or detail work where precise control matters. Avoid using with very dirty or contaminated metals without proper prep.
Buying Guide
What to consider when choosing 7018 welding rods:
- Rod diameter and box size: Choose a size that matches your project thickness and welding machine output. Smaller diameters are easier to control on thin material; larger ones deposit more metal for thicker sections.
- Coating and hydrogen content: Low-hydrogen coatings reduce cracking risk, especially in high-tillet or structural steel welds. Ensure proper storage to prevent hydrogen pickup.
- Position capability: All-position rods (V, H, for vertical and overhead) are versatile for complex joints, while certain diameters may perform best in specific positions.
- Material compatibility: Ensure the rod chemistry aligns with your base metals, including carbon steel, high-tensile steel, or low-alloy steels.
- Power requirements: Check whether your welder supports AC/DC and the current range recommended for the rod size and thickness.
- Bead finish and cleaning: Look for electrodes with smooth arc, easily removable slag, and a bead that meets your cosmetic and structural needs.
Frequently Asked Questions
- What is 7018 welding rod best used for?
Best for all-position welds on carbon steel and low-alloy steels with good impact toughness, especially in structural applications. - Do 7018 rods require special storage?
Yes. They should be kept in a dry, controlled environment to maintain the low-hydrogen coating and prevent moisture pickup. - Can I use 7018 rods with both AC and DC power?
Many 7018 rods are designed for AC/DC compatibility, but confirm the electrode packaging or manufacturer guidance for your specific lot. - Which diameter should I choose for thin sheet metal?
3/32″ to 1/8″ rods work well for thin sheets, offering better control and reduced heat input. - Is one brand superior to others?
Performance varies by rod diameter, coating quality, and storage. The best option aligns with your material, welding position, and machine setup. - What should I do if I see excessive spatter?
Check amperage settings, base metal cleanliness, and ensure proper shielding gas coverage if applicable; adjust to reduce spatter and improve bead appearance.
