## How to Use AWS E7018 Welding Electrode.
**1. What is AWS E7018 Welding Electrode?**.
AWS E7018 welding electrode is a type of rod used in shielded metal arc welding (SMAW). It is known for providing high-quality welds with good toughness, ductility, and crack resistance. The "E" stands for electrode, "70" refers to the tensile strength (70,000 psi), "1" indicates it can be used in all positions, and "8" signifies the type of flux coating and current options available.
**2. What are the preparation steps before welding with AWS E7018?**.
Before starting to weld with an AWS E7018 electrode, follow these preparation steps:
- **Ensure Clean Surface:** Clean the welding surface thoroughly to remove any rust, oil, paint, or other contaminants. This ensures a strong bond.
- **Dry the Electrodes:** E7018 electrodes are low-hydrogen rods and must be kept dry to prevent weld defects. Store them in a heated oven at 250°F to 300°F to keep moisture out.
- **Select Proper Settings:** Adjust the welding machine according to the electrode manufacturer’s guidelines. Typically, E7018 electrodes work well with Direct Current Electrode Positive (DCEP).
**3. How to perform the actual welding process with AWS E7018?**.
During the welding process, follow these steps for optimal results:
- **Strike the Arc:** Start by striking the arc smoothly. Avoid striking like a matchstick to prevent spatters.
- **Maintain Proper Arc Length:** Keep the arc length short, about the diameter of the electrode core wire. A long arc can cause excessive spattering and instability.
- **Correct Angle and Movement:** Hold the electrode at about a 20° angle relative to the workpiece. Move steadily along the welding line with consistent speed and pressure.
- **Control the Heat:** Adjust the speed to ensure adequate penetration without burning through the material. Listen for a consistent buzzing sound, which indicates stable welding.
**4. What are some tips for troubleshooting common issues?**.
If you encounter problems, consider these tips:
- **Porosity:** If you see small holes in your weld, it could be due to moisture. Ensure your electrodes are dry and the welding surface is clean.
- **Cracking:** Maintain the right temperature and do not allow the weld to cool too quickly. Preheating the workpiece can sometimes help.
- **Inconsistent Weld Beads:** Verify your travel speed and ensure proper electrode angles. Inconsistent speed can cause irregular beads.
**5. What are the safety measures to follow when using AWS E7018?**.
Always prioritize safety by adhering to these measures:
- **Wear Protective Gear:** Use a welding helmet with a proper shade, gloves, fire-resistant clothing, and safety glasses.
- **Ventilation:** Weld in a well-ventilated area to avoid inhaling fumes. Use exhaust systems or fans if necessary.
- **Check Equipment:** Regularly inspect your welding equipment and tools for any damages or wear.
By understanding these basic guidelines and preparation steps, you can effectively use AWS E7018 electrodes to produce high-quality welds. Always refer to the specific manufacturer's instructions and maintain a keen eye on safety to ensure successful welding operations.
