c. AWS Approved Steels. The steels listed in Annex M are approved for use, but Welding Procedure
Specifications (WPSs) must be qualified prior to use in welding these steels. These steels are generally
quenched and tempered steels, which are sensitive to temperature changes from welding operations that
may affect their strength, ductility, and toughness. They are also generally more sensitive to diffusible
d. Matching Filler Metals for Prequalified Steels. Table 4-1 provides a summary of structural steels
that are both approved by AISC and listed by AWS as prequalified. For joint designs requiring "matching"
filler metal, the "matching" filler metal for the given welding process is provided.
