In GTAW, what is the term for the beads formed during the welding process?

In Gas Tungsten Arc Welding (GTAW), the term used to describe the beads formed during the welding process is "weld beads." These beads are the solidified metal deposits that result from the molten filler material being added to the weld pool as the tungsten electrode generates an electric arc.

Weld beads are critical for both the strength and appearance of the weld. Properly formed beads indicate good control over the welding process, ensuring that the materials have fused correctly and that there are no defects such as undercutting or inadequate penetration. They are typically characterized by a smooth, uniform surface that resembles a small ridge along the weld line.

Other terms like weld pools refer specifically to the liquid state of the metal before solidification occurs, while weld dabs may describe small amounts of filler material added during the process. Weld fillets typically refer to the joint configuration rather than the bead itself. Understanding these distinctions is important for anybody engaged in welding, particularly when assessing the quality and characteristics of a weld joint.
