Joint Types and Their Impact on Weld Strength

Today, we will delve into this subject in great detail and unravel the influence of various joint types on the strength of welds using these two electrodes.

Before we dive in, let’s first understand the significance of these numbers. 8010 and 7018 are welding rods or electrodes that are utilized to produce an electrical arc for welding purposes. These numbers are part of the American Welding Society (AWS) classification system, with the first two digits representing the tensile strength of the electrode and the last two digits indicating the welding position and coating type.

Now, let’s address the fundamental question – is 8010 inherently stronger than 7018? The concise response is affirmative, but it’s not as straightforward as it seems. While 8010 boasts a higher tensile strength of 80,000 psi compared to 7018’s 70,000 psi, other factors also play a crucial role in determining the overall strength of a weld.

One crucial factor is the type of joint being welded. There are four primary types of joints in welding – butt joint, lap joint, T-joint, and corner joint. Among these, a butt joint is considered to be the strongest as it facilitates full penetration and allows for more deposition of weld metal. This is where 8010 gains an edge over 7018, thanks to its superior tensile strength and penetration capabilities, making it an ideal choice for butt joints.

However, in lap joints where partial penetration suffices, welds using 8010 may exhibit slightly lower strength due to its lower deposition rate compared to 701This highlights the importance of selecting the appropriate electrode for the specific joint type being welded.

Best Practices for Using 8010 and 7018 in Different Positions

Mastering the art of welding requires more than just choosing the right numbers for your welding rod.
