Node imperfection

Nodular irregularity is a geometric flaw in the overlap of multiple welds, usually caused by poor heat treatment. Requires careful visual inspection.

Physical-Chemical Mechanism

Nodular irregularity occurs when several welds do not overlap correctly or heat treatment is uneven. This leads to uneven stresses and distortion in the material.

Metallurgical Relevance & Welding Risks

This irregularity can cause cracks, fractures, or reduced mechanical properties of the weld. It compromises the strength and service life of the component.

Workshop Practice & Procedures

To avoid nodular irregularities, ensure uniform heat treatment and inspect the weld using visual inspection techniques. Use specialized tools like microscopes for detailed examination when needed.
