Contacts welded with Synrad's Evolution Series 200W sealed CO2 laser.

Two spot welds
The fine control of the laser is once again highlighted in this welding application. The 0.01"-thick contact was welded to the main body with two spot welds. The spot welds provide excellent strength, while ensuring that the battery's internal components are not overheated during the process. In addition, the weld only partially penetrates the underlying thickness, so that the battery casing remains sealed.
