What is the welding joint coefficient φ
A coefficient used to measure the proportion by which the strength of the welded joint is reduced compared to that of the base material.
The weld joint coefficient refers to the ratio of the strength of a butt weld joint to the strength of the base material. It is used to reflect the degree to which the strength of a welded joint is reduced due to factors such as welding materials, welding defects, and welding residual stresses, and it represents a comprehensive indication of the mechanical properties of the welded joint.
