E7015 Welding Electrode
AWS E7015 welding electrode
Description:
E7015 welding electrode is a type of low-hydrogen, iron powder electrode that is used primarily for welding mild and low alloy steels.
Features :
It is characterized by its excellent welding performance and superior mechanical properties, making it ideal for use in a variety of applications.
One of the main advantages of the E7015 welding electrode is that it has a low hydrogen content, which helps to prevent cracking and porosity in the weld. Additionally, its high iron powder content provides for strong, stable arc performance and improved deposition rates.
Applications:
Used for welding important medium carbon steel and low alloy steel structures (under pressure and dynamic load), such as 16Mn, 09Mn2Si, 09Mn2v, and ship grade A, B, D, E steel, etc., also used for thick plates.Welding of carbon steel structures with poor weldability.
In order to ensure safe and effective use, it is important to follow proper welding procedures and techniques when using the E7015 welding electrode. This includes using the appropriate amperage and voltage settings, maintaining a clean and dry work surface, and properly storing and handling the welding electrode.
The E7015 welding electrode typically comes packaged in standard 10 lb. boxes, with each electrode measuring approximately 14 inches in length. It is important to keep the electrodes dry and protected from moisture during storage and transportation.
ATTENTION:
1. Before welding, the welding rod must be baked for 1 hour at a temperature of 350 ° C and used as needed.
2. Before welding, impurities such as rust, oil stains, and moisture must be removed from the welded parts.
3. Short arc operation must be used during welding, preferably with narrow weld beads.
