Parent Metal Group
Base material groups are categories of materials with similar properties and compositions. They simplify the selection of welding procedures and testing methods.
Physico-Chemical Mechanism of Action
Base material groups classify metals according to their chemical compositions and metallurgical properties. These categories help predict the behavior of materials under welding processes.
Metallurgical Relevance & Welding Risks
Assigning a material to a base material group is crucial for the correct selection of welding methods and parameters. Wrong assignments can lead to insufficient strength, porosity, or hot cracking.
Workshop Practice & Action Instructions
When welding, it is important to use the material that belongs to the correct base material group. Check the chemical composition and properties of the material before starting the welding process. Use appropriate welding procedures and testing methods to ensure the quality of the weld is guaranteed.
