Tire Bead: The tire bead is the part of the tire that fits onto the rim of the wheel. It forms a seal with the rim to keep the tire inflated, especially in tubeless tires.
Bead (Particle): A small ball-like particle used in processes like bead blasting or sometimes found in catalytic converters for various purposes.
Weld Bead: In welding, the bead refers to the appearance of the finished weld. It describes the neatness and uniformity of the ripples formed by the melted metal during the welding process.
Trimming and Sealing: In automotive or upholstery contexts, bead can refer to a formed, often ornamental molding used for sealing or trimming purposes. For example, it might be used between fenders and the body of a car, or in vehicle upholstery as flexible welting.
