in garment manufacturing, the point where sections are joined in clothing, footwear, and the like. There are three types of seams: stitched, glued, and welded. Stitched seams are the most common. Welded seams are used for garments made of thermoplastic fabric or films; they are ordinarily produced by the heat, ultrasound, or high-frequency method. Welded seams may be segmented to reduce rigidity if the seal does not have to be airtight.
