Micro laser welding
Laser welding is a process with a high energy density. It is a connection method that can be adapted very well to to precisely weld small elements with low distortion.
The process can be used for welding of metals and even for plastics. It should be noted that reflecting metals (such as copper and aluminium) show a lower process efficiency.
Laser welded stainless steel foil (0,1 mm thickness)
Heat exchanger with curved plates with a thickness of 0,1 mm. These were welded with pulsed laser welding.
