Dear Expert,
Greetings of the day.
I have a doubt on welding high strength material YP690, jack-up rig.
Currently we are using E111T1-GM H4, 80%Ar - 20%CO2, 1.2mm wire size.
Recently client is insisting on changing to 1.6mm wire size for higher productivity & efficiency.
However in my opinion, using 1.6mm requires usage of higher welding current 350A & above,
And not all welders are able to handle such high ampere & speed, this might cause some defects.
In addition, my concern is high heat input & cooling rate.
I have explained all this details to client, but client don't accept.
