What is an 8018 welding rod?
The 8018 welding rod is an all-position low-hydrogen electrode that is mainly used for welding low-alloy steels. It is designed for high-impact strength and low-temperature applications, making it ideal for welding heavy equipment, pressure vessels, and pipelines.
The E8018 electrode is designed to produce high-quality welds with excellent strength and crack resistance, particularly in high-stress applications where the welded joints may be subjected to high loads or impact forces. The low hydrogen content of the electrode helps to prevent hydrogen-induced cracking, which can occur when welding high-strength steels.
Characteristics of 8018 welding rod
The 8018 welding rod has several unique characteristics that make it suitable for specific welding applications. Some of these characteristics include:
Low hydrogen content
One of the defining features of the E8018-B2 electrode is its low hydrogen content. This makes it an excellent choice for welding high-strength steel, as it reduces the risk of hydrogen cracking.
High tensile strength
The E8018-B2 electrode has high tensile strength, which makes it ideal for welding structures that are subject to high stress, such as bridges and buildings.
Low-temperature properties
The 8018 welding rod has excellent low-temperature properties, making it suitable for welding in cold environments.
Welding with E8018-B2 electrode
Welding with the E8018-B2 rod requires skill and expertise. Here are some tips to ensure a successful weld:
Prepare the metal
Before welding, it is essential to prepare the metal properly. This involves cleaning the metal to remove any impurities, and ensuring that it is free from any oils, grease, or other contaminants.
Choose the right amperage
To ensure a successful weld, it is essential to choose the right amperage for the welding job. This will depend on several factors, including the thickness of the metal, the welding position, and the type of joint.
Keep the electrode dry
The welding rod is a low-hydrogen electrode, which means that it is susceptible to moisture. It is essential to keep the electrode dry by storing it in a dry place and using a moisture-resistant container.
Applications
The E8018 electrode is a type of low-hydrogen, iron powder, coated electrode that is commonly used for welding high-strength steels. The “E” in the electrode classification system stands for electrode, while the “80” indicates a minimum tensile strength of 80,000 psi, and the “18” indicates the position in which the electrode can be used, which in this case is all positions (flat, horizontal, vertical, and overhead).
The E8018 electrode is typically used in industries such as construction, shipbuilding, and heavy equipment manufacturing, where high-strength materials are commonly used. It can be used to weld a variety of steels, including carbon steels, low-alloy steels, and high-strength steels, and is often used in applications where the welded joint will be subjected to high stress or impact forces.
