The utility model relates to an ultrasonic detection device. According to the technical scheme, the welding seam full-focusing probe device based on the direct longitudinal waves and the double linear arrays comprises a phased array linear array, a wedge block, a sound matching layer, a protection film and a damping block which are installed in a probe shell, and the phased array linear array keeps signal conduction with the outside through a wire; the phased array linear array is characterized in that the wedge block is a double-inclined-surface wedge block, and the phased array linear array comprises a one-dimensional small-angle phased array linear array and a one-dimensional large-angle phased array linear array which are connected to the lower surface of the damping block in a front-and-back mode; the double-inclined-surface wedge block is positioned at the lower part of the probe device, and double inclined surfaces at the top end of the double-inclined-surface wedge block are matched with the array pla
