Hi Kingnero ,

We have a 1600 amps CV power source .

Thanks

Nice.
SAW or ESW?

a 60mm wide strip should be easily doable with your source, at speeds over 8" a minute, depositing roughly 20 kg/hour.

Hi Kingnero ,

Thank you for your input . Its ESW . Will the parameters remain same for both SAW / ESW ?

 

[kingnero]

No, as ESW has a higher deposition rate it will also need adjusted parameters as well as compatible fluxes.
You will have to perform testing as to ideal bead profile, overlap, penetration/dilution, if necessary chemical analysis, ...
You won't find all those details online. Ask your filler material supplier for aid, they will most certainly be able to show you a WPS from which you can finetune to your specific needs.
