Is it the thickness X width ...waht you have mentioned ?

If so is there any chart mentioning busbar carri ying above 5000 A current either in copper or aluminium

What else would it be, other than thickness and width?

(And it's copper, as mentioned in the OP; rather than aluminum, which was not mentioned.)

Then make it wider and/or thicker, or two busbars in parallel.

There have been many threads about this on CR4, oftentimes mentioning 1100 amperes per inch2 ≈ 1.7 amperes per mm2 for copper. There is some variation depending on surface area and ambient temperature. For better heat dissipation, if needed, you could go thinner but wider.

Google "busbar calculation" or "busbar area" to discover more.

If you want to be fancy (least area), you could use silver....

I've used 3/8 X 8" for 4000A so go for 3/8 X 12"

As i mentioned it is 6000A DIRECT CURRENT with 8 volts ......

Operating Temperature : 32oC

Process : Electrochemical

Material of interest : copper

Conditions: The is no voltage fluctuations as it is a potentiostatic rectifier

Has to be welded to Nickel Electrodes

Help me out in

1.Size calculation

2.heat generation formula

3.insulating the bus-bar

4. how to take connections from busbar to electrodes ? Through whar king of wires ?

You are obviously not qualified for the job you seem to have. Any first year apprentice wireman can figure this out.

Until "you" can explain yourself clearly how are we supposed to explain "you" to yourself clearly?
