Panasonic makes very good quality stuff. I think the tricky part is getting all the batteries connected in series and parallel with those nickel tabs. Usually, people use a big machine that uses 2 pulses. The first pulse vaporises the impurities on the 2 surfaces, and the next pulse of about 3000 amps welds them together. I bet there's a way to do that that's similar to a motor controller. PWM can do anything. The pulse is for only needed for a couple millisec I think.
