Base Material Grouping
Base material grouping is a classification of metals into similar property groups to simplify welding processes.
Physico-chemical mechanism of action
Base material grouping classifies metals into categories based on their chemical compositions and metallurgical properties. These groups have similar welding behavior and requirements.
Metallurgical relevance & risks in welding
Proper selection of the base material group is crucial for the success of the welding operation. Wrong groups can lead to undesirable microstructures, hardness issues, or failures.
Workshop practice & action instructions
Before applying a welding process, the base material must be identified and classified into the appropriate group. This is done through chemical analysis or knowledge from the manufacturer. For each group, specific welding parameters such as temperature, voltage, and time must be followed.
