• Laser welding is the very latest technology for solar absorbers, solving the inefficiencies and problems of other methods.
• Laser welding technology allows long-term stability and thermal shock durability.
• Laser welding results in ideal heat transfer and in turn the highest performance because the join is perfect and because the surface is not damaged by the process, unlike the ultra-sonic method. The heat transfer is more efficient than in any other joining method giving the best results for the absorber strips.
• The specific laser method enables complete welding of the aluminium and copper without limitations on the design imposed by other methods, which can be affected by factors such as material thickness, tube spacing and tube diameter.
• The selective coating is not in any way damaged by laser welding, meaning that the absorber’s appearance remains excellent. Professionals and consumers agree that laser welding uses cutting edge technology to great performance and a brilliant appearance.

How does it work?

The welding is achieved by focusing the laser beam through the acute angle formed by the copper tube and the aluminium/copper plate.

Material from both tube and plate melts forming an excellent weld without the addition of any filler material.
