Question: QW-403.9 states: "For single or multipass welding in which any pass is greater than 1/2 in., an increase in thickness beyond 1.1 times that of the qualification test coupon." Does the phrase "...greater than 1/2 in..." refer to width or thickness?

Reply: The phrase shown in the Question refers to the thickness of any pass.
