What is the term used for the angle between the joint and the electrode along the axis of the weld?

The term that refers to the angle between the joint and the electrode along the axis of the weld is known as the travel angle. This angle plays a critical role in determining how the arc is directed and can influence the characteristics of the weld, such as penetration and bead shape.

When the welder positions the electrode, the travel angle helps establish the direction and stability of the weld pool, which is essential for achieving quality welds. A proper travel angle ensures optimal heat input and effective fusion between the base materials being welded.

In contrast, the work angle describes the angle between the workpiece and the electrode in a lateral sense, which affects the weld bead width and penetration differently. The push angle refers to the technique of pushing the electrode away from the weld pool, while the pull angle involves pulling towards the welder. These terms are important too, but they do not specifically define the angle between the joint and the electrode along the weld axis as accurately as the travel angle does.
