Can undermatching be used for Prequalified?

e.g.  I want to weld the A572 GR65 to A572 GR65 , according to the table 2.3 or 2.6, we can determine the filler metal strength requirements to undermatch base metal strength. Can we use prequalified here, if any other condtions is suit for the code.

Hi, Gizmo,    I interpret the Pre-Qualified section of the code that,  yes, undermatching filler metals are permitted under specific conditions (with reference to Clause 3.3 and the Tables 2.3 and 2.6).

The second paragraph in 3.3 states that the Matching / Undermatching table [in Clause 3.3 which references Tables 2.3 and 2.6] SHALL be used in conjunction with Table 3.1.      

Regards, Sol
