When a fillet welding symbol does not include the weld size, it is typically assumed that the weld size should be equal to the leg length of the fillet. In this case, if you have 1/4"x4"x10' square tubing steel studs welded to a 1/2"x8"x8" anchored plates, the leg length of the fillet weld should be 1/4 inch.
