Revolutionary Technology for Battery Industry<\/strong><\/h3>\n

Laser Welding is a revolutionary technology for welding batteries that are highly sensitive to thermal effects. For instance, laser welding has already been widely used in lithium-ion battery fabrication^{1<\/sup> . In addition, the laser welding process uses a low heat application \u2013 the weld is formed as the intense laser beam rapidly heats the material in a non-contact way, typically in milliseconds.  This laser application minimizes any damage to the components or materials.<\/p>\n}

Benefits of Welding Batteries with Lasers<\/strong><\/h3>\n

The main parts that can be welded with laser technology are battery tabs, busbars, and connectors. Laser allows the wiring of these parts with different shapes: spot, line, hollow circle, triangle, etc. Given this flexibility, laser technology offers much more benefits:<\/p>\n

\n
• Low heat input and high energy density result in high weld quality and productivity^{2<\/sup>.<\/li>\n}
• High pull strength;<\/li>\n
• Higher overall joint strength due to the ability to make more welds (greater total welded area) in a smaller space;<\/li>\n
• While joining dissimilar metals, laser welding technology reduces the thickness of the intermetallic layer, minimizes the formation of pores and cracks, and increases the mechanical properties of the weld^{3<\/sup>.<\/li>\n}
• Faster manufacturing cycles as laser welding is >5 times faster than MIG and >10 times faster than TIG;<\/li>\n
• Flexibility in overlapping spot design;<\/li>\n<\/ul>\n

  Our Recent Case<\/strong><\/h3>\n

  Recently, our engineer welded battery tabs at the client\u2019s factory with a handheld* laser welding system. Wiring 400 battery cells, with two battery tabs on each battery and 8 points for each tab (client\u2019s request). This work took 5 hours for a total of 6400 points. See the pictures below for the results of laser welding for batteries. 
  *Option with complete automation of the process with robot hand, including handling and testing is available. Our Laser systems operate 24\/7.<\/p>\n
