A laser welding apparatus for welding a workpiece in a welding zone, comprising
- a first clamping jaw comprising an array of laser diodes arranged to emit laser light and a transparent body arranged to receive and transmit the laser light into the workpiece, wherein the array of laser diodes is arranged in proximity to the transparent body, the transparent body having a clamping surface arranged to come into contact with the workpiece.
A method of laser welding a workpiece in a welding zone, comprising:
- arranging the workpiece between a first clamping jaw and a second clamping jaw, the first clamping jaw comprising a two-dimensional array of laser diodes and a transparent body, the transparent body having a clamping surface arranged to come into contact with the workpiece, wherein the array of laser diodes is arranged in proximity to the transparent body,
- clamping the workpiece between the clamping surface of the transparent body and the second clamping jaw along the welding zone,
- causing at least a part of the laser diodes to emit laser light and transmitting the laser light through the transparent body along the welding zone into the workpiece.
