摘要
A method and apparatus for high speed welding are disclosed wherein a continuous weld is formed at high speed along a member with a plurality of overlapping welds formed by pulses of high density energy from a pulsed high energy density welding device such as an electronically pulsed gas laser. The movement of the member being welded is detected in the vicinity of the pulsed laser. The pulsed laser is controlled in response to the detected movement so that the energy for welding from the pulses per unit length of the member being welded is accurately controlled. The control of the laser involves pulsing of the laser in response to the detected movement of the member so that the pitch of the overlapping welds along the member is substantially constant. Also, the power of the laser pulses is controlled and adjusted in a predetermined manner in response to the detected movements. The high speed movement of the member is detected by detecting the leading edge of the moving member at or upstream of the pulsed laser and also continuously decteing the position of the moving member at or as it moves past the pulsed laser. High quality welds can be made in materials at speeds of 22-40 m/min. or more with the method and apparatus.
