code is not restricted to use these consumables but WPS shall refer the same consumable which to be used at the time of welding ,
you need to revise this WPS using the same PQR and submit it for client approval before proceeding for welding , u need to mention consumable type which you wants go for
check client Specification for consumable restrictions against PQR qualified with.
Techinca part : each consumable has its own advantages but ER70S-6 is better for strength and impact applications , one must know that Mn provides better strength and toughness to the weldments. So, any loss of Mn from the weld deposit will actually reduce the strength , more silicon present in ER70S-6 consumable will make a good weld bead appearance.
