“…Rotational dowel welding, instead, is very flexible, needing only inexpensive but good quality hand or fixed drills, and presents no limitations of application. It has been and is already being used in small workshops for some biofurniture, assembly of small wood pieces, and room refitting [133][134][135][136][137][138][139][140][141][142]. Some temperature-welded plywood has also been prepared, but its hot press time is far too long to be of industrial significance [143,144].…”

This review presents first, rather succinctly, what are the important points to look out for when preparing good wood composites, the main types of wood composites manufactured industrially, and the mainly oil-derived wood composite adhesives and binders that dominate and have been dominating this industry. Also briefly described are the most characteristic biosourced, renewable-derived adhesives that are actively researched as substitutes. For all these adhesives, synthetic and biosourced, the reviews expose the considerable progresses which have occurred relatively recently, with a host of new approaches and ideas having been proposed and tested, some even implemented, but with even many more already appearing on the horizon.

“…A minimalist Z chair was built by rotational dowel welding without using any wooden or metallic angular supports. The dowels were welded at two different angles to minimise the leverage action on the joints (Renaud 2009).…”

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

“…and beech (Fagus sylvatica L.), were undertaken largely on small pieces, but much larger specimens (Fig. 2) were also used [31][32][33][34][35][36][37][38][39][40]. At the same time, attempts have been made to adapt other types of wood, aluminum, metal, and plastic welding to small parts, such as ultrasonic and micro-motion welding techniques [11,41].…”

Wood plays a major role in the production of furniture and wooden structures. Nevertheless, in this process, the massive use of adhesives and plural connectors remains a definite problem for health and the environment. Therefore, wood welding is a breakthrough in this respect. This paper reviews the applications of wood welding in furniture and construction and then examines advances in improving the durability of welded wood against water. Our contribution also highlights the need to join African tropical woods using the rotational friction welding technique. According to our results, these woods present interesting chemical singularities, which could provide solutions to the water vulnerability of the welded wood. Moreover, the use of such a joining method would first free the Cameroonian furniture industry from the chemical industry, secondly position it at the forefront of new eco-design trends and thirdly make it competitive with other countries in the Central African sub-region. These works enrich the long and rich bibliography on the technique of wood welding, which has long been conspicuous by its absence of tropical woods.
