What metallurgical tests ensure the weldability of dissimilar metals in mixed-material animal sculptures?
Ensuring the weldability of dissimilar metals in mixed-material animal sculptures requires rigorous metallurgical testing. Key tests include:
1. Chemical Composition Analysis – Identifies elemental compatibility to prevent adverse reactions like galvanic corrosion.
2. Tensile and Shear Testing – Evaluates joint strength under mechanical stress.
3. Microstructural Examination – Assesses grain structure and potential intermetallic phases that could weaken welds.
4. Hardness Testing – Ensures uniform hardness distribution to avoid brittleness.
5. Non-Destructive Testing (NDT) – Uses X-ray or ultrasonic methods to detect internal flaws.
These tests ensure durable, artistically viable welds in complex sculptures blending metals like steel, bronze, or aluminum.
