Welding Electrode Metalweld RUTWELD12 4.0 mm rutile 6 kg

Metalweld RUTWELD12 rutile-covered welding electrode, diameter 4.0 mm, pack weight 6 kg is designed for manual shielded metal arc welding (SMAW) of general structural steels. The rutile flux coating provides a stable, smooth arc and produces a relatively soft, easily removable slag. Electrodes perform well in flat and vertical welding positions and are suitable for construction, repair and metal fabrication environments where straightforward welding characteristics and good bead appearance are required.

Advantages

The rutile coating ensures reliable arc starting and a stable arc with low spatter levels, which simplifies post-weld cleaning. The formulation yields good wetting on the base material for uniform bead shape and reduced undercut. Easy slag detachment speeds up successive welds, and consistent coating quality across the 4.0 mm electrodes supports predictable deposition rates and operator control in common structural applications.

Suitable for

• General structural steel welding in construction and fabrication
• On-site repair and maintenance of steel components
• Welding in flat (1G/1F) and vertical (3G/3F) positions
• Workshops producing frames, supports and welded assemblies

Key specifications

• Diameter: 4.0 mm
• Pack weight: 6 kg
• Recommended application: general structural steels
• Welding positions: flat and vertical
• Arc characteristics: smooth, stable arc with low spatter
• Slag behaviour: soft, easy to remove

How to use

Prepare weld surfaces by removing rust, oil and loose scale for consistent arc behavior and weld quality. Select appropriate welding current according to electrode diameter and material thickness; for 4.0 mm electrodes refer to standard SMAW current ranges for rutile electrodes and adjust for operator technique and position. Strike the arc, maintain a steady travel speed and an appropriate work angle for flat or vertical welding. After welding, chip off the slag and inspect the bead for penetration, fusion and any defects. Store unused electrodes in a dry, low-humidity environment to prevent moisture pickup and maintain welding performance.

Usage recommendations

For reliable results, use recommended current settings for 4.0 mm rutile electrodes and preserve electrodes in sealed packaging or a dry oven if long-term storage is required. When welding vertical joints, control heat input to limit sagging and adjust travel speed for uniform bead formation.
