The laser welding system for photovoltaic junction boxes typically comprises several key components: a control system, laser generator, temperature management unit, vision and lighting modules, welding modules, dust extraction systems, and product handling mechanisms.
[pdf] The method comprises the following steps: preparing a material to be welded; the material to be welded at least comprises a battery piece and a welding strip; applying pressure to the welding strip and the battery piece in the material to be welded by using a vacuum adsorption pressing plate mode, so that the welding strip and the battery piece are attached; and carrying out multi-welding point position processing on the materials to be welded after the welding belt and the battery piece are attached by adopting a laser beam splitting processing mode.

[pdf] today, contact-free infrared, hot air or la-ser soldering is used to connect tin-plated copper ribbons to the screen-printed metal-lization on the frontside and the backside of the adjacent cell. the resulting solar strings then are arranged onto a lamination foil and joined by cross-connectors.
[pdf] Laser welding enables precise and efficient connection of tabs to the battery cell body, with high welding speeds, a minimal heat-affected zone, and minimal damage to the cell’s internal structure.
[pdf] There is a possibility to weld carbon steel plates with thickness up to 12 mm by using solar energy source instead of electrical energy source. There is a stable arc length and smooth welding process with low welding smoke can be obtained in case of using solar energy source.
