Product Details

Multi-Layer Depth Profiling Indentation Tester PMT-1000

Stress Gradient Analysis for Thick-Section Welds

Product Summary

The Non-Destructive Weld Stress Indentation Tester (Model PMT-1000) is engineered for stress gradient analysis in thick-section welds. Using multi-layer indentation along depth, it provides detailed stress profiles essential for life assessment and failure analysis in pressure vessels, pipelines, and heavy equipment.

Key Features

Depth Profiling: Obtains stress gradients through multi-layer indentation, revealing how stress varies through the weld thickness.
Optimized PWHT: Measures stress changes before and after post-weld heat treatment to optimize PWHT parameters.
Direct Stress Calculation: Directly calculates welding residual stress from indentation curves without calibration.
High Data Rate: 100 Hz data acquisition captures rapid stress variations accurately.
Material Flexibility: Suitable for stainless steel, duplex, and nickel alloys, including difficult-to-weld materials.
