扫描焊接
一种塑料焊接工艺：变幅杆（通常为条形变幅杆）在大面积扁平塑料件上横向移动（或塑料件相对于变幅杆移动），从而获得远大于变幅杆端面接触面积的焊缝。塑料可以是织物材料，在变幅杆与连续旋转的滚筒之间输送。
Scan welding
A plastic welding process where a horn (usually a bar horn) moves laterally over a large, flat plastic part (or vice versa) in order to produce a weld that is much larger than the contact area of the horn face. The plastic can be a fabric material that moves between the horn and a continuously rotating drum.
