Intensity of Restraint of Weld Joints Restrained by Shearing Force Through Fillet Welds (Part 1)

Measurements of the reaction stress and the intensity of restraint were undertaken and the results were compared with the analytical results in Part 1.Experiments were made for two types of specimens, H-type and T-type (see Figs. 14 (a) (b) ), in which bending moment by reaction forces may or may not be neglected respectively.Some analyses showed good agreement between test results and calculations (see Figs. 17 (a) (b)). It was found that the occurrence of weld joints might be estimated by comparison of the Kcr-value with the K-value. The necessary value of uncompleted fillet-weld length 2Δ to prevent weld cracking may be obtained from equation (14) for given values of joint geometry, size of fillet and welding heat input.
