YESWELDER Mild Steel TIG Rod ER70S-6
ER70S-6 is a gas-shielded copper-coated carbon steel rod designed for mild steel fabrication. It features a strong combination of manganese and silicon deoxidizers, enabling higher welding currents with 100% CO2 shielding gas. This composition helps produce a smoother bead with minimal post-weld cleanup. It’s well-suited for a range of mild and low alloy steels, especially where higher deposition efficiency is desired. Flux and coating influence spatter and bead appearance; selecting the right shielding gas mix can further improve results.
YESWELDER E7018 3/32″ 5LB
E7018 electrodes are low-hydrogen iron powder-type rods suitable for all-position welding on AC or DC reverse polarity. They excel in welding medium-grade carbon steels where no preheat is used and can help reduce porosity on cold-rolled steels. The rods provide a steady arc, low spatter, and strong re-striking ability, delivering high deposition efficiency for consistent, quality welds across structural and fabrication tasks.
ARCCAPTAIN E7018 Welding Rod 3/32″ 5LB
This ARCCAPTAIN E7018 option is a 3/32″ diameter low-hydrogen iron powder electrode, designed for all-position welding with both AC and DC reverse polarity. It provides excellent x-ray quality welds, high tensile strength, and good resistance to cracking, making it a practical choice for structural steel and fabrication applications that demand reliable performance in varying positions.
ARCCAPTAIN ER308L TIG Filler Rod
ER308L is a low-carbon stainless TIG welding rod with corrosion resistance suitable for stainless steel welding. It is sized at 1/16″ diameter and 16″ length, designed for full-location welding with 100% Argon or Argon/Helium shielding gas. This rod is ideal for joining stainless components where maintaining corrosion resistance and a clean weld bead is important, complementing mild steel work when stainless transitions are present.
UNIFAMILY ER308L 1/16″ TIG Rod
UNIFAMILY’s ER308L TIG welding rods offer low-carbon stainless steel capabilities with good corrosion resistance. At 1/16″ x 16″ in length, these rods are designed for reliable TIG welds on mild and low-alloy steels converted to stainless sections. They pair with argon-based shielding gas mixtures and are noted for smooth weld seams and reduced post-weld cleanup. They’re a practical choice when stainless needs intersect with carbon steel projects.
YESWELDER E308L-16 Stainless Steel Stick Electrodes
E308L-16 stainless steel electrodes are used for stainless welding, supporting all-position work. They are designed for unstabilized stainless steel and provide a smooth arc with low spatter and a self-peeling slag. This rod is suitable for repairing and fabricating stainless components in automotive, kitchen equipment, and industrial settings where corrosion resistance matters.
Saker E6013 Welding Rod 3/32″
The E6013 is a versatile low-carbon steel electrode suitable for AC and DC welding. It delivers excellent results on a wide range of welding applications, including lower-voltage machines. All-position welding, easy arc start, minimal spatter, and a flux coating that aids slag removal make the E6013 a reliable choice for beginners and professionals alike.
TOOLIOM Mild Steel TIG Rod ER70S-6
TOOLIOM’s ER70S-6 TIG filler rod is copper-coated for mild steel, designed for use with argon-CO2 mixes or 100% CO2 shielding gas. The 3/32″ diameter and 16″ length offer a stable arc and reduced spatter, enabling high welding current operations. This rod mirrors the performance of standard ER70S-6 with emphasis on smooth bead appearance in typical steel fabrication settings.
Buying Guide: Key Considerations For Steel Welding Rods
- Material compatibility: Mild steel rods (ER70S-6, E7018) suit most structural and fabrication tasks. Stainless rods (ER308L) provide corrosion resistance for stainless-to-steel transitions.
- Shielding gas and process: MIG/TIG processes depend on shielding gas composition. CO2 or Argon-CO2 mixes influence bead smoothness, penetration, and spatter. E7018 rods pair well with multiple currents and require proper control of hydrogen content.
- Rod diameter and length: 1/16″ to 3/32″ diameters cover many thin to mid-thickness steel applications. Longer lengths reduce frequent rod changes during longer runs, especially for TIG work.
- Position of welding: All-position electrodes (E7018, E6013) allow vertical and overhead welding. Some rods are optimized for specific positions; choose accordingly for your project.
- Strength and weld quality: Low-hydrogen rods (E7018) often yield higher x-ray quality welds and reduced cracking risk in critical joints. Flux-coated rods typically require slag removal for a clean weld.
- Storage and handling: Low-hydrogen rods need proper storage to prevent moisture uptake. Keep in a dry, sealed environment and rotate stock to ensure freshness.
- Application scope: For stainless components or where corrosion resistance is necessary, ER308L-based rods are preferred. For general structural steel, ER70S-6 and E6013 options cover most needs.
