Adhesiveless bonding of wood – A review with a focus on wood welding

Most industrially used synthetic wood adhesives release formaldehyde, which is carcinogenic for humans. Adhesiveless bonding of can be achieved using heat treatment by either hot-pressing method, suitable mainly particles and fibres or welding. Welding wood, relies on the generated via friction, two more solid pieces together. The process carried out linear rotational This review first considers manufacturing binderless wood-based panels hot-pressing. Then this followed an in-depth outlook welding its application in industry. effects varying parameters, such as applied pressure, vibrational frequency amplitude, holding time, time welding, relative diameter difference between substrate dowel to obtain joints with optimal mechanical physical properties reviewed discussed. Wood products made (hot-pressing welding) are environmentally friendly, brief curing times needed their manufacture represent a great advantage compared usage bind wood.
