ESAB welding electrode OK 46.16 D 4.0 mm, flux-coated stick electrodes, 5 kg

ESAB welding electrode OK 46.16 D 4.0 mm is a flux-coated stick electrode supplied in a 5 kg pack, intended for manual metal arc (MMA) welding of steel. This electrode is formulated for general-purpose joining and repair work, providing a stable arc and reliable weld metal suitable for maintenance, fabrication and on-site applications. The 4.0 mm diameter balances deposition rate and control, making it suitable for medium-thickness steel work where a flux-covered consumable is preferred.

Advantages

OK 46.16 D electrodes deliver consistent arc stability and a smooth slag profile to simplify slag removal. The flux coating provides good weldability on a variety of steel surfaces, tolerating typical site conditions and minor surface contaminants. Supplied in a 5 kg pack, these electrodes offer a practical quantity for workshop and field use, allowing uninterrupted welding sessions with an electrode designed for predictable performance.

Suitable for

• General-purpose steel fabrication and assembly
• Maintenance and repair of structural and mechanical components
• On-site welding where portability and flux-coated electrodes are preferred
• Medium-thickness plate welding and joint work using MMA process

Key specifications

• Electrode type: flux-coated stick electrode for manual metal arc (MMA) welding
• Diameter: 4.0 mm
• Packing: 5 kg coil/pack of electrodes
• Application material: carbon and low-alloy steels
• Arc characteristics: stable arc with controllable deposition rate

How to use

Select appropriate welding current and polarity according to electrode diameter and base metal thickness, and ensure proper electrode holder connection and cable condition. Clean the weld area from heavy rust, oil and loose scale for best results; light surface contamination is tolerated but cleaning improves weld quality. Strike the arc and maintain a steady travel speed and correct electrode angle to control penetration and slag formation. After welding, allow the slag to cool and chip it off, then inspect the weld bead for continuity and sound fusion.

Usage recommendations

Store electrodes in a dry environment to prevent moisture pickup. For critical or high-strength applications, perform welding procedure tests and post-weld inspection as required. When working outdoors or in variable conditions, adjust welding parameters to maintain arc stability and ensure proper slag removal between passes.
