As per ASME SEC IX ,we qualified PQR(SMAW/GMAW process) with 8mm/10 mm thickness plate full penetration welding( Root Land:1mm to 1.5 mm) as root ,hot and cap welding and then back/root side of plate was grounded(approx 2mm) to sound metal and one pass of cap welding was done in root side.
My question is whether is method is considered as welding with backing or with out backing it is considered as backing. how?
