Parent Material Grouping
Base material grouping is a classification of materials based on their metallurgical properties to simplify the required testing.
Physico-Chemical Mechanism of Action
Base material grouping is based on the chemical compositions and the microscopic structure of metals. These properties determine how the material behaves at different temperatures and stresses.
Metallurgical Relevance & Welding Risks
Incorrect assignment to a material group can lead to inappropriate welding processes. This can cause deterioration of mechanical properties, increased stress failure, and reduced component life.
Workshop Practice & Action Instructions
Before choosing a welding process, it is crucial to identify the exact material and correctly assign it to the corresponding base material group. This is done through material testing such as chemical analysis or microscopic examination of the structure.
