1. A weld inspection method, comprising:
transmitting an ultrasonic wave to a weld portion at a transmission angle;
detecting an intensity of a reflected wave from the weld portion at a plurality of points in a transmitting direction of the ultrasonic wave; and
setting the transmission angle based on a tilt angle, the tilt angle indicating a tilt of the weld portion and being calculated using a gradient of the intensity for each of the plurality of points.
