e. Matching Filler Metals for Non-prequalified Steels. Table 4-2 provides "matching" filler metal
information for structural steels approved by AISC, but not listed as prequalified by AWS D1.1.
Quenched and tempered steels are not listed in this table. With the exception of A992, the advice of a
competent welding consultant should be used prior to welding these steels. A992 steel is a new steel
specification which is essentially a more restricted A572, grade 50 steel.
