ABSTRACT:
A method of controlling a movable energy source includes controlling the velocity and the power of the energy source moved along the predetermined path in accordance with a difference between the predetermined and the measured temperature at different areas of the surface. A signal to control the movement of the energy source is provided when the path of the source is approximated by a broken line represented by the piecewise linear function or arcs of circles of different radii. The power of the source is varied in proportion to the average deviation of the measured temperature from the predetermined one for each area of the surface. The velocity of the source is controlled using the signals representative of the difference between the predetermined and the measured temperature. An apparatus for carrying out this method includes a temperature sensor, a signal forming unit adapted to form the signals representative of the correction values of the velocity of the source, and a functional signal converter adapted to convert the latter signals to the signals representative of the components determined by the law of movement of the source.
