摘要：
This study examined the mechanics and temperature during a wood dowel welding process. The test results indicated that the welded depth 40 mm showed the highest pullout resistance. Based on the mechanics and surface morphology, welded depth 30 mm was the optimal parameter. A nonlinear relation existed between pullout resistance and welded depth. The highest temperature of six test points was studied in group of welded depth 30 mm. With the increasing of depth, the highest temperature of six test points showed the decreased trend. A linear relation was found between the highest temperature of welding interface and the depth.
