Battery and laser welding
« on: July 12, 2024, 08:30:11 pm »
Anyone has any experience with laser welding when connecting batteries?
(Spot welding is not powerful enough for our need)

AAA? AA? Car batteries? Truck batteries?

    They spotweld steel car frames together so I have to wonder what size battery cells the OP is talking about.  All of the LARGE cells that I've seen have all been connected by bolted on straps or cables of some sort.  The largest battery cells that need to be spotwelded that I'm aware of are D sized cells and a spotwelder can certainly handle those.  X-cells are larger but have terminal lugs on them.

   The OP needs to tell us more about what she's trying to do.

You can get spot welders in excess of 200KVA for a few thousand dollars. You can't get a laser that is that powerful for anywhere near the cost.
AFAIK laser battery welders are chosen for speed not for power.
