Figure 3.1—Tolerances in Assembly of Groove Weld Butt Joints—Dry Welding at the job site and at the depth at which production welding; will take place. At least one confirmation weld, excluding automated welding, shall be satisfactorily completed for each welding system to be used during production. The confirmation test weld shall be a fillet break weld conforming to the requirements of section 5.11.7 except that the length shall be a minimum of 200 mm (8 in.). Unless otherwise specified by the Customer, the requirements of 3.4.2, 3.4.3, and 3.4.4 apply.

3.4.2 Base Metals. The base metal for the confirmation weld should be 10 mm (3/8 in.) minimum thickness and carbon equivalent within 0.05 of the maximum CE of the base metal welded in production.

3.43 Position. Where the production weld is to be made in only one welding position, the confirmation weld shall be made in that position. Where welding in more than one position is necessary, the confirmation weld shall be made in the position in production in which the majority of welding will be done or as directed by the Customer.

3.4.4 Examination Requirements. Each confirmation weld shall undergo visual inspection and fillet break testing, except that Class C welds require only visual examination. Macroetch testing shall not be required. The test plate may be cut into smaller sections by any convenient means (e.g., oxygen-acetylene) to facilitate breaking. However, cutting shall not interfere with evaluation of the root pass start and stop. Acceptance criteria shall be as specified in sections 7, 8, 9, or 10 for the class of weld.

3.5 Dimensional Tolerances

The sizes and lengths of welds shall not be smaller than those specified. Fillet weld sizes shall not exceed
