What action must be taken if a contractor performs unauthorized welding on structural steel in the shop or in the field?
• A. Correction of unauthorized welding on structural steel will require the following: All weld metal shall be removed using a method to ensure that the structural steel base metal is not nicked or undercut. Generally, the weld is removed by grinding. Following removal of the weld metal, testing of the Heat-Affected Zones (HAZ) must be evaluated by Magnetic Particle Testing to assure that there are no cracks. The limits of the HAZ area to be tested will be specified by the Office of Materials. If cracks are found, additional grinding to remove the crack will be required or the structural steel member may be required to be replaced. Hardness tests will be required, using the Rockwell Methods, to determine that the HAZ remaining in the structural steel is not in an unacceptable hard condition. If the hardness is unacceptable, additional grinding to remove the hardened zone will be required or the structural steel member may be required to be replaced. All correction work shall be under
