7018 (3.2mm) – E7018 Electrode (1/8 inch) – Usage and Advantages
Usage:
- Welding Position: All positions (flat, horizontal, vertical, overhead)
- Base Metals: Low to medium carbon steel, structural steel, and mild steel
- Applications:
- Structural welding (bridges, buildings, ships)
- Pressure vessels and piping
- Industrial fabrication
- Repair and maintenance work
- Power Source: Requires DC+ (reverse polarity) or AC
- Electrode Diameter: 1/8 inch (3.2 mm) – suitable for medium to heavy thickness materials
Advantages:
- Low Hydrogen Content: Reduces risk of hydrogen-induced cracking
- Smooth, Strong Welds: Produces high-quality, ductile welds with good impact strength
- Easy Slag Removal: Slag peels off easily, improving efficiency
- Good Arc Stability: Makes welding easier and more consistent
- Moisture Resistance: Iron powder coating helps resist moisture absorption when stored properly
