Sentence:  Besides bondline thickness control, the adhesive fillet (called adhesive <WSD>spew</WSD>) is an important issue in joint assembly. The <WSD>spew</WSD> is the result of the adhesive squeezed out of the lap region at the moment of the joint manufacture. It was shown that significant increases in shear strength of lap joints, compared with square-ended bondlines, can be achieved through the formation of an adhasive <WSD>spew</WSD> at the overlap ends. 
Meaning of the word marked with <WSD> tags:  Adhesive that is squeezed from a joint under pressure and held across the joint by a fillet, thereby strengthening the joint.
