FYI, AWS recently released a new standard, "D1.7/D1.7M:2010, Guide for Strengthening and Repairing Existing Structures."
It provides engineers and contractors with general direction and guidance on weld repairs, weld strengthening, and other procedures to correct problematic issues with existing structures made of steel (minimum yield strength of 100 ksi and minimum thickness of 1⁄8 inch), cast iron, and wrought iron.
It's useful to the engineer who is obligated under D1.1 Clause 8 to plan for projects that involve strengthening and repairing. Preview it at
