Dear All,

Last line of QW-403.5 "This variable does not apply when impact testing of HAZ is not required by other sections". Can you please elaborate it. I cannot understand what it wants to convey?
 
Sometimes construction codes such as Sec VIII Div. 1 will specify impact testing of the weld metal only. When this is the case, this variable does not apply.
 
Or when no impact testing is required. So, if your intended application does not require impact testing by Code rules, the welding variable does not apply.
