Portable Nondestructive Weld Stress Tester – PMA-1010 for Dissimilar Metal Welds
The PMA-1010 is a portable nondestructive indentation tester specifically designed to evaluate interface stress in dissimilar metal welds such as aluminum-steel and titanium-steel. It measures stress distribution on each material side, enabling complete weld stress field evaluation without cutting or damaging the component.
Product Summary
This device performs rapid, on-site residual stress measurements in dissimilar metal welds. It uses the indentation energy difference method to evaluate interface stress without causing structural damage. The instrument is insensitive to weld reinforcement and undercuts, simplifying surface preparation and ensuring accurate readings even on complex geometries.
Key Selling Points
- Dissimilar Metal Weld Capability: Evaluates interface stress and stress distribution on each material side of aluminum-steel and titanium-steel welds, facilitating quality control in critical joints.
