What does the term "weld bead" mean?

The term "weld bead" refers to the visible line of weld material that is deposited on the base metal during the welding process. This weld bead is the result of melted filler material, which solidifies as it cools, forming a joint that bonds the materials together. The characteristics of the weld bead, such as its width, height, and appearance, can indicate the quality of the weld and the welding technique used. Understanding the properties of the weld bead is essential for evaluating the integrity and strength of the weld. In welding practice, recognizing the significance of the weld bead helps welders assess their work and make necessary adjustments to improve the results.
