The best method to do Al bus bar is GMAW (MIG) process. !50 mm thick bus bars
were successfully welded for more than 125 joints earlier and still being done including
repair work of bus bars.. It has fully replaced SMAW, which was used in earlier days.
Filler wire : AWS /SFA- 5.10 ER 4043, size - 1.60 mm
Gas : Argon 99.98% purity rate of flow- 16-18 lpm.
Amps : 250 to 300, Volts-30 to 32
Polarity : DC EP
Tr.Speed : 250 mm/min (avg)
Pr-Heat : 150 deg C.
Joint type : 60 deg. partial groove butt & 'V'30 deg. K fillet -double bevel fillet
Arc Time : 40 to 45 mts.
Heat input :1.80 to 2.0 kj/mm.(average)
Test done : Conductive Test.
Code : AWS D 1.2
Cost economics: 1/3 the cost of SMAW process
Hope above details will be of use to you.

I have Aluminum plate sections to be welded for a power station
busbar. The plate is 200 mm wide, 150 mm thick in the vertical 3F
position. There are over 100 joints to be welded. GMAW and GTAW may
be out of the question due to the sheer volume of weld metal required
for each joint. Please offer time saving suggestions.
