What is the maximum reinforcement value for groove weld root and cover passes as given in CSA W59?

• A. 1/8 in
• B. 1/4 in
• C. 3/16 in
• D. 1/2 in

Answer: (A)

Reinforcement is the amount of weld metal that sticks above the surface of the base metal after welding. For groove welds in CSA W59, the limit on how much weld can protrude applies to both the root pass and the cover passes, and it is set at 1/8 inch. This keeps the weld profile predictable, helps avoid excessive distortion, and ensures proper penetration and inspection. Measure perpendicular to the joint surface at the weld; if a pass would exceed 1/8 inch, the weld should be dressed or otherwise adjusted to meet the limit. Larger values, like 1/4 inch, 3/16 inch, or 1/2 inch, are not permitted for groove weld root and cover passes under this standard.
