On Comparison with Fillet Welded Joints

Abstract

By experiments on the test specimens of 7 kinds of butt welded joints connected by lateral, frontal and oblique (45°) fillets respectively or combinatively which have equal throat sectional areas, the author measured the deformation resulting from tensile static load, strength of the joint and inclination of the breaking surface of fillet.
From these measured results, the author made comparative studies in regard to the following items.
Strength of the joint, the max. shearing stress in fillet at the elastic and ultimate loads, inclination of the breaking surface of fillet, deformations of the joint and apparent modulus of elasticity of the joint.
