Consider Penetration When Determining Fillet Weld Size

Practical Ideas for the Design Professional by Duane K. Miller, Sc.D., P.E. Design File Introduction A flat-faced, equal-legged fillet weld in a 90° T-joint has a theoretical throat dimension of 0.707 ω, where ωis the leg size (Figure 1). This assumes fusion is achieved to the root of the joint, but not necessarily beyond that point.
