- Table OW-264 has a new requirement that includes carbon equivalent limits for applicable steel alloys, when laser welding is performed, in order to address the increased risk of any cracks occurring.
- A new paragraph in QW-403 also includes the new variable for a change in base metals.
- Table QW/QB-422 has been revised to include:
· Weld metals based on SFA classification: SFA-5.9, SFA-5.18, & SFA-5.28
· An explanatory note-QW-424.3
· Base metal specification and grades for IRAM-lAS U500-42, an Argentinian standard for structural use of hot rolled carbon steel sheets.
- Nonmandatory Appendix-L has been revised to further clarify the qualification requirements for welders and welding operators.
