Non-Destructive Weld Stress Tester for Dissimilar Metal Welds
Product Summary
The PMA-1010 Non-Destructive Weld Stress Tester specializes in evaluating interface stress in dissimilar metal welds, such as aluminum-steel and titanium-steel combinations. It measures stress distribution on each material side, providing critical data for assessing weld quality and integrity in demanding applications.
Key Features
Dissimilar Metal Weld Evaluation: Evaluates interface stress in dissimilar metal welds (e.g., aluminum-steel, titanium-steel).
Per-Side Stress Measurement: Measures stress distribution on each material side of dissimilar metal welds.
Surface Preparation Not Required: Insensitive to weld reinforcement or undercuts, requiring no complex surface preparation.
Non-Destructive and Safe: Creates indentations of only a few microns, not affecting subsequent NDT, and poses no ionizing radiation risk.
High Accuracy: Data acquisition rate of 100 Hz ensures precise stress data.
