Distributed imperfection
Scattered irregularity refers to acceptable individual irregularities distributed throughout the weld metal, whose cumulative frequency must meet standard limits. These irregularities can appear as discontinuities or deviations.
Physical-Chemical Mechanism
Scattered irregularities refer to the allowable individual irregularities distributed across the weld metal. These can occur as defects or deviations and are limited by specific standards.
Metallurgical Relevance & Welding Risks
These irregularities can lead to deformations or weak points in the weld metal if they exceed allowable limits. It is important that the cumulative frequency of irregularities stays within standard values to ensure the overall weld integrity.
Workshop Practice & Actions
To control scattered irregularities, welding parameters must be precisely maintained. This includes correct temperature management and adherence to specified standards for allowable frequency of defects or deviations. If these standards are violated, measures should be taken to improve the welding process.
