Dear Friends

We are presently trying to use a local make 4.8mm dia SAW filler wire (EM12K)in place of 3.15mm dia.
Can anyone tell us the correct welding parameters like:
current, voltage, travel speed,etc for 4.8mm dia wire..
The base metal is SA516Gr.70, the thickness is 70mm. The joint is single bevel groove joint with no access from other side. Presently we weld first 2 passes with TIG, Then 2 passes of SMAW and then subsequent passes with SAW-3.15mm dia. Now we want to use 5.0mm dia SAW wire. So what should be the welding parameters ? We have tried various parameters for SAW(4.8mm dia wire) but failed to get good weld finish /UT. We have a 1200A Lincoln Power source.
The joint calls for UT.

Regards
