Laser Beam Welding is a fusion welding process in which two metal pieces are joined together by the use of a laser. The laser beams are focused on the cavity between the two metal pieces to be joined. The laser beams have enough energy and when they strike the metal pieces produce heat that melts the material from the two metal pieces and fills the cavity.

6 FAQs about [Photovoltaic energy storage laser welding principle diagram]

What is a laser beam welding diagram?

Laser Beam Welding Diagram The diagram of laser welding is as follows- In the diagram, the workpiece is positioned under the laser beam. Next, it is directed onto the area where the weld is to be created. The laser beam heats the workpiece, causing it to melt. This forms a pool of molten material in the weld region.

How does laser beam welding work?

Laser Beam Welding (LBW) is a welding process, in which heat is generated by a high-energy laser beam targeted on the workpiece. The laser beam heats and melts the edges of the workpiece, forming a joint. The energy of a narrow laser beam is highly concentrated at 10 8 -10 10 W/cm 2, so a weak weld pool is formed very rapidly (for about 10 -6 sec).

How is laser welding used for metallization and interconnection of solar cells?

Laser welding is used for the metallization and interconnection of solar cells. Figure 21 (Schulte-Huxel et al. 2016) shows the interconnection of two cells using laser welding of Al foil.
