Portable Non-Destructive Weld Stress Tester for Pipe Girth Welds On-Site
Product Summary
The PMA-1010 Non-Destructive Weld Stress Tester is specifically designed for on-site measurement of axial and hoop residual stresses in pipe girth welds. Its portable and one-person operable design makes it ideal for complex welding sites, including high-altitude or remote areas. Using the indentation method, it provides rapid and accurate stress data without causing any damage to the pipe surface.
Key Features
Rapid On-Site Measurement: Simultaneously measures axial and hoop residual stresses in pipe girth welds, providing complete weld stress field evaluation in minutes.
Portable and One-Person Operable: Lightweight design allows easy handling in complex welding sites like high-altitude or remote areas.
Non-Destructive: Creates indentations of only a few microns, not affecting subsequent NDT and completely safe for operators and the environment with no ionizing radiation risk.
Insensitive to Surface Conditions: Insensitive to weld reinforcement or undercuts, requiring no complex surface preparation.
High Data Acquisition Rate: 100 Hz data acquisition rate ensures accurate capture of stress variations.
