This equipment is used to automatically string-weld solar cells with 5, 6, 9, 10, 11, 12, 20 grid lines into battery strings according to set parameters. It uses infrared welding method; solder paste immersion supply; automatic feeding positioning and pulling belt.
[pdf] One of the main advantages is their ability to deliver consistent and precise welds. The fixed position ensures welds are applied exactly where needed, leading to higher quality and uniform results. Spot welding is a quick process that doesn’t require filler materials.
[pdf] Issue: One of the most frequent problems is when the machine doesn’t deliver enough welding power to create a strong bond between the metal pieces. Solution: To address this issue, check and, if necessary, replace the welding electrodes, and ensure the capacitor energy storage unit is fully charged.
[pdf] Common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and arc welding. MIG welding is ideal for its speed and ease of use, while TIG welding offers greater precision for intricate designs.
[pdf] In busbar welding or cell connector welding, the cell connectors are pressed onto the cell poles without a gap using a hold-down device and then welded with a laser. This method ensures a precise and stable connection, which is necessary for the performance and safety of the battery.
