A laser welding method and system join portions of two workpieces of thermoplastic material by clamping together the portions of the workpieces to be joined, against a baseplate engraved or etched to form an image to be replicated in the joined portions of the workpieces, and applying laser radiation to the portions of the clamped workpieces to be joined, to melt those portions of the clamped workpieces to be joined and to replicate the image in the joined portions of the clamped workpieces when the material solidifies. The thermoplastic material of the workpieces can be optically transparent but absorbs a portion of the laser radiation, so that both workpieces are heated and melted by the laser radiation. A portion of the melted workpiece material flows into the engraved or etched portions of the baseplate, forming an embossed surface on the lower surface of the area where the workpieces are joined.
