The invention discloses a production method for a maximum-intensity surface wave, wherein the production method comprises the following steps: 1) selecting a straight probe, selecting a plurality of acoustically transparent wedges, making the acoustically transparent wedges and the straight probe form a surface wave probe, and selecting an arbitrary acoustically transparent wedge as a to-be-tested acoustically transparent wedge; and 2) coating a position of the to-be-tested acoustically transparent wedge making contact with the straight probe with a coupling agent, then fixing the straight probe on the to-be-tested acoustically transparent wedge, next placing the to-be-tested acoustically transparent wedge on a to-be-tested workpiece surface, making the straight probe generate a surface wave, allowing the surface wave to be incident into the to-be-tested workpiece surface through the to-be-tested acoustically transparent wedge, then reflecting back through the to-be-tested workpiece surface, measuring whether the amplitude value of the wave reflected back through the to-be-tested workpiece is 80% of full screen, when the amplitude value of the reflected wave is 80% of full screen, recording the surface wave probe composed of the current to-be-tested acoustically transparent wedge and the straight probe as an optimal surface wave probe, and generating the maximum-intensity surface wave through the optimal surface wave probe. The method can generate the maximum-intensity surface wave.
