摘要：Welded headgear sections can be produced by using a weld tool having pinsprotruding from a weld region contact surface to deliver high-frequency electromagneticenergy to a weld region defined by overlapping top and bottom headgear straps. The
pins fully penetrate the top strap and at least partially penetrate the bottom strap. Thepins concentrate the electromagnetic energy to achieve a weld joint of acceptable weldstrength and aesthetic appeal.
