Radial groove concentricity
Radial joint concentricity describes the concentration of stresses in the weld around the cylinder axis. High values lead to increased hardness and risk of cracking.
Physical-Chemical Mechanism of Action
Radial joint concentricity is a measure of stress distribution in the weld, especially in cylindrical components. It describes how strongly stresses concentrate around the cylinder axis.
Metallurgical Relevance & Welding Risks
High radial joint concentricity leads to increased hardness and susceptibility to cracking in the weld. This can cause hot cracks or material failures, especially if cooling is too fast.
Workshop Practice & Action Guidelines
To minimize radial joint concentricity, ensure a uniform heat treatment concept. Use controlled cooling and avoid rapid cooling. For cylindrical parts, it is especially important that the weld is symmetrical around the axis to create uniform stresses.
