点焊
一种塑料焊接工艺，其焊点直径相对较小（在 20 kHz 下通常小于 20 mm），且塑料材料的熔化发生在整个焊点直径范围内（而非仅沿边界熔化）。常用的点焊变幅杆包括指数形、悬链线及类似的实心圆柱形变幅杆。
Spot welding
A plastic welding process where the weld diameter is relatively small (typically less than 20 mm at 20 kHz) and melting of the plastic material occurs completely across the weld diameter (as opposed to melting only along a boundary). Common spot welding horns include exponential, catenoidal, and similar solid cylindrical horns.
