A PQR was qualified as per ASME SEC IX with two process, GTAW and SMAW with weld metal deposit thickness (t) of 8 mm each in a 16mm base metal thickness (T) of plate. What will be the BASE METAL THICKNESS range T (not deposited weld metal thickness) if a WPS is prepared with only GTAW process supporting the above PQR?.
Here are few ranges;
1). Base metal thickness range 5 mm to 32 mm and deposited weld metal thickness upto 16mm
2). Base metal thickness range 5 mm to 16 mm with a max deposited weld metal thickness of 16 mm
3). Base metal thickness range 1.5 mm to 16 mm with a max deposited weld metal thickness of 16 mm
Which would be selected from the above. Considered all other essential variables are ok and no supplementary essential variables are applicable here.
Please share your knowledge and much more appreciated if your statement can be made referenced with the applicable clause of the code.
