Welding Electrode ESAB OK 46.16 D2.5 5 kg

ESAB OK 46.16 D2.5 5 kg welding electrodes are general-purpose coated MMA electrodes designed for manual metal arc welding of carbon and low-alloy steels. Supplied in a 5 kg pack, these electrodes deliver a stable arc, good bead appearance and consistent mechanical properties suitable for fabrication, repair and maintenance work. The OK 46.16 classification denotes a rutile-based coating that supports easy striking and re-striking of the arc and provides smooth slag removal for efficient multi-pass welding.

Advantages

The electrodes provide stable arc characteristics and predictable weld profiles, which help reduce rework and improve productivity in routine welding tasks. Their rutile coating ensures easy arc starting and smooth slag detachment, while also producing a compact, uniform bead with moderate spatter levels. The 5 kg pack format is convenient for workshops and on-site jobs where a reliable, general-purpose steel electrode is required.

Suitable for

• Manual metal arc (MMA) welding of carbon and low-alloy steels
• General fabrication and structural welding
• Maintenance and repair of steel components and machinery
• Multi-pass welding where consistent slag removal is important

Key specifications

• Electrode type: Rutile-coated MMA electrode for steel welding
• Diameter: 2.5 mm
• Pack weight: 5 kg
• Welding current: Suitable for DC and AC MMA welding (follow equipment settings)
• Typical properties: Stable arc, good bead appearance, smooth slag removal

How to use

Select an appropriate welding current and polarity for 2.5 mm rutile-coated electrodes according to the welding equipment manufacturer’s recommendations. Clean the weld area from rust, oil and contaminants before welding. Strike the arc and maintain a consistent travel speed and angle to achieve an even bead. Allow slag to cool slightly before chip-off and brushing to reveal the finished weld profile. Store the electrodes in a dry environment to maintain coating integrity.

Usage recommendations

For best results, use these electrodes on clean steel surfaces and match welding parameters (current, polarity and travel speed) to the 2.5 mm diameter. When performing structural or critical repairs, verify mechanical requirements and perform appropriate post-weld inspection. Keep the pack sealed and store electrodes in a dry, low-humidity area to avoid coating contamination.
