Product Overview
AWS E12015-G low alloy steel electrode is a high-performance low hydrogen iron powder electrode designed for welding low alloy steel pressure vessels and other high strength structures with a tensile strength of 830MPa. It adopts advanced formula and strict production process to ensure that the welded joint has excellent mechanical properties and crack resistance, and is suitable for welding operations under various harsh working conditions.
Core advantages
- High strength matching: Meets the welding requirements of 830MPa low alloy steel, and the weld metal strength is perfectly matched with the base material
- Excellent low temperature toughness: Maintains good impact toughness at -40℃, suitable for application in cold areas
- Low hydrogen characteristics: Diffusible hydrogen content ≤5ml/100g, effectively preventing cold cracks
- Arc stability: The arc is stable during welding, with little spatter, beautiful shape, and easy operation
- All-position welding: Can be performed in all positions such as horizontal, vertical, horizontal, and vertical, with strong adaptability

Instructions for use
1. Before welding, the electrode must be baked at 350-400℃ for 1 hour and placed in an 80-100℃ insulation cylinder for use
2. Remove impurities such as oil, rust, and moisture within 20mm of the weld groove and both sides
3. Use direct current reverse connection (DCEP), and the welding current should be selected according to the electrode diameter, weld thickness and joint form
4. Short arc operation should be maintained during welding, and the interlayer temperature should be controlled at 150-250℃
5. After welding, stress relief treatment should be performed at 250-350℃×1-2 hours
FAQ
Q: What is the difference between AWS E12015-G and other types of welding rods?
A: AWS E12015-G is a high-strength low-alloy steel welding rod with a tensile strength of 830MPa, which is higher than the ordinary E7018 welding rod (490MPa), and is suitable for welding occasions with higher strength requirements.
Q: Is this welding rod suitable for welding in low-temperature environments?
A: Yes, this welding rod has excellent low-temperature toughness, and the impact energy can still be maintained at more than 47J at -40℃, which is suitable for use in cold areas or low-temperature conditions.
Q: What should I do if pores appear after welding?
A: Porosity is usually caused by improper cleaning of the weldment surface or improper baking of the welding rod. Make sure to thoroughly clean the weldment surface before welding, and bake and keep the welding rod at the specified temperature.
