Weld spatter refers to small droplets of molten metal that are expelled during the welding process and can land on surrounding surfaces. This phenomenon typically occurs due to the high heat involved in welding, which can cause some of the material being welded to splatter away from the weld pool. While weld spatter is a common occurrence, it is generally considered undesirable as it can lead to additional cleanup work and may affect the quality of the finished weld if not managed properly.

The other options touch on different aspects of the welding process: the process of adjusting the welding torch is an important skill for welders but does not define weld spatter itself. A welding helmet is essential for safety during welding operations, but it does not relate to the definition of weld spatter. The sound made during welding can vary but does not encapsulate the definition of weld spatter either. Thus, understanding this specific term helps welders prepare adequately for maintaining a clean workspace and enhancing the quality of their work.
