摘要

The possibility of welding wood dowels into low-density plywood substrates without a pilot hole was investigated. Sharpened beech wood dowels with a diameter of 10 mm were inserted into plywood plates made from poplar and paulownia wood at a rotational rate of 1500 rpm with a manually operated drill press. This process resulted in welded joints of considerable strength. When poplar was used, withdrawal strengths as high as those of adhesive bonds were achieved.
