NOTES: 1. Total cladding thickness should be approximately equal to the unmachined thickness to be deposited in production, with adequate allowance to permit machining the entire weld surface while maintaining minimum required thickness (see notes 2, 3, 5(c), and 6). The number of weld layers at the minimum machined thickness used for qualification (see note 2) shall equal the minimum number of layers to be used in production. For cladding of cylindrical materials, also see figure 7-5. 2. Base Metal Thickness, Weld Thickness, and Minimum Number of Weld Layers. (a) T is the test assembly nominal base metal thickness. (1) For T = 1 inch or greater, qualified base metal thickness is 1 inch and greater. (2) For T less than 1 inch, qualified base metal thickness is T and all greater thicknesses. (b) Where composition testing is performed (see notes 5 and 6) the machined weld thickness and number of layers present at which composition testing is performed shall be the minimum qualified. (c) Where dilution testing is performed in lieu of composition testing (see notes 5(c) and 7), the minimum qualified weld thickness and layers shall be either of the following, as applicable: (1) Three layers and the machined weld thickness at which 3 layers are obtained, but no less than ¼ inch (see note 5(c)(1)); or (2) Two layers and the machined weld thickness at which 2 layers is obtained, but no less than 3/16 inch (see note 5(c)(2)). (d) Maximum weld thickness qualified shall be twice the machined weld thickness at which NDT and bend testing are performed.
