Question

The maximum combined warpage and tilt of a flange permitted by CSA W59 is:

a) 1/10 x flange width, no maximum
b) 1/50 x flange width, no maximum
c) 6 mm
d) 1/100 x flange width, 6 mm maximum

Answer 1

The maximum permissible combined warpage and tilt for a flange according to CSA W59 is 1/100 x flange width with a 6 mm maximum limit. The flange warpage should not exceed the lesser of the calculated value or 6 mm.

Step-by-step explanation:

By the CSA W59 standards, which pertain to the welding and fabrication of steel structures, the acceptance criteria for flanges address the combined warpage and tilt tolerances. The maximum allowed warpage and tilt for a flange is defined as a proportion of the flange width or as an absolute measurement in millimeters.

The four options provided suggest varying limits based on a ratio of the flange width or a fixed millimeter criterion. More specifically, the correct answer is 1/100 x flange width with a maximum limit of 6 millimeters. This means that the combined warpage and tilt should not exceed the product of the flange width divided by 100 or 6 mm, whichever is less. So, if a flange is 200 mm wide, the maximum permissible warpage and tilt would be the lesser of 2 mm (1/100 of 200 mm) or 6 mm, which in this case would be 2 mm.
