Grinding the weld toe is the most popular method for improving the fatigue strength of fillet welded joints. Tool for grinding can be divided into two types; they are burr type grinder and disc type grinder. The disc type grinder is apt to make notches on the weld, and difficult to be applied to finish the weld toe due to its shape. However, disc type grinder is sometimes adopted in the actual treatments because it is easy to handle. This study is aiming at malting clear the influence of the grinding method on the fatigue strength of out-of-plane gusset welded joints through the fatigue tests and stress analyses.
