You can usually pop those welds,  they're only small spots.  Also,  if you
want to make a replacement pack get the cells with the tabs,  and simply
solder them,  unless you have access to some place that can make the welds.
 Soldering to the battery cases doesn't usually work well,  and it damages
them.

That is odd.
