Current Carrying Capacity in Folded Copper Strips

[Frank]

If a copper strip is folded, is the current capacity changed? Assuming the fold isn't a sharp "crease" in the material, is there any reason to suspect it won't be able to handle as many amps? I'm thinking of soldering a bus bar onto some copper sheet, welding the sheet onto my cells ("sandwich" method), then bending the sheet up on itself to cover the cells, hopefully without creasing the copper strip. Thoughts, opinions, etc. appreciated!

I suspect it will work just fine. The current will take the most direct path, and any added mass in the copper conductors will act as a heat-sink and "radiator"
