Abstract
The present invention provides a square-wave laser seal pattern made by first directing a laser beam onto an shaft while the shaft is moving in a horizontal direction relative to a laser device so as to create a horizontal laser seal bond segment. Next, with the shaft rotating about a shaft longitudinal axis, the laser beam is directed onto the shaft so as to create a vertical laser seal bond segment. By alternately creating and coupling together a plurality of horizontal and vertical laser seal bond segments, a square-wave laser seal is formed around a circumference of the shaft. The shaft's movement in a horizontal direction relative to a laser beam may be either at a constant speed or a variable speed so as to control the amount of laser energy heat impacting the shaft material.
