Causes of differential behavior of extractives on the natural cold water durability of the welded joints of three tropical woods

This study aims to investigate the causes of the differential behavior of extractives on the water resistance of the welded joints of three tropical woods. The welded joints of these chemically characterized woods were obtained by rotational dowel welding. The respective extractives contents obtained during the successive extractions were 12.98 ± 0.90% for Iroko, 17.36 ± 0.40% for African pearwood and 18.16 ± 1.00% for Padauk. Phytochemical...
