A laser welding system for joining first and second thermoplastic workpieces, and including a clamp, an actuator, and a laser source. The clamp includes first and second clamping structures positioned together to engage opposite sides of the workpieces when they adjoin each other. The first clamping structure has a non-flat or irregular surface, facing the first workpiece. The actuator causes the clamping structures to press the first and second workpieces together. The laser source applies laser radiation having a wavelength of 2 microns toward the workpieces to be joined, while they are pressed together by the clamp, to melt irradiated portions of the workpieces to one another. The first clamping structure transmits substantially all of the energy of the laser radiation through the material. The first workpiece has a non-flat or irregular surface facing the first clamping structure, which substantially conforms with the surface of the first clamping structure.

In an embodiment, a method of forming a cooling plate, comprises laser welding a plurality of weld lines to physically connect a first substrate and a second substrate wherein the plurality of weld lines forms an inflatable track; and inflating the inflatable track with an inflation fluid to form a cooling channel in the cooling plate. In another embodiment, the cooling plate can comprise a first substrate and a second substrate and a plurality of weld lines can form a fluid tight seal for a cooling channel located therebetween.

Laser welding device (1000) includes: laser oscillator (100); optical fiber (300) that transmits a laser beam (LB) generated in laser oscillator (100); laser beam emitting head (400) that is attached to the emission end of optical fiber (300) and emits laser beam (LB) toward workpiece (600); manipulator (500) with laser beam emitting head (400) attached thereto; and controller (200) that controls laser beam emitting head (400) so as to cause laser beam (LB) to be scanned three-dimensionally on the surface of workpiece (600). Controller (200) controls laser beam emitting head (400) so as to change a focal position of laser beam (LB) in accordance with a shape of a welded portion in workpiece (600).
