Question

Two plates are welded as shown. As per NSCP specifications, the effective area of fillet welds shall be taken as the effective length times the effective throat thickness and the maximum size of fillet welds that is permitted along the edges of connected parts shall be:

* Material less than 6 mm thick, not greater than the thickness of material
* Material 6 mm or more in thickness, not greater than the thickness of material minus 1.6 mm.

The plates are 12 mm thick and 350 mm wide. Nominal tensile strength (Fu) of weld is 550 MPa. Allowable shear stress is 0.30Fu.

1. Which of the following most nearly gives the maximum size of fillet weld, in mm?
