In the automotive industry, laser welding is acquiring more and more importance. The ability of the laser to bundle light energy to form the finest beams which can even weld metals opens up new possibilities in terms of body quality and stability because weld seams can be made extremely narrow and precise.
The very powerful, focused light of laser welding produces very high temperatures which melt the material at a focal point of around 0.5 to 1 millimetre in diameter. Because of the narrow working area, laser welding technology is particularly suitable for butt welding sheets.
The advantages are to be found in the higher strength of the joint and new opportunities for design.
