Product Details

Dissimilar Metal Weld Stress Tester PMT-1000

Stress Analysis for Bi-Metallic Welds

Product Summary

The Non-Destructive Weld Stress Indentation Tester (Model PMT-1000) is specialized for measuring stress distribution in dissimilar metal welds, such as those between stainless steel and carbon steel. It provides separate stress readings for each material side, enabling a clear understanding of the bi-metallic joint behavior.

Key Features

  • Per-Side Stress Measurement: Measures stress distribution on each material side of dissimilar metal welds.
  • Compatibility with Difficult Materials: Evaluates stress on stainless steel, duplex, and nickel alloys.
  • Extremely Small Indentations: Creates indentations of only a few microns, preserving surface integrity and not affecting subsequent NDT.
  • Non-Distorting: Performs non-distorting stress tests on sheet metal welds, such as auto body spot and seam welds.
  • No Calibration Needed: Directly calculates welding residual stress from indentation curves.

Models and Options

Model: PMT-1000. Special fixtures for dissimilar metal joints can be provided.

Materials and Structure

Works on cemented carbide, stainless steel, aluminum alloy, and addresses challenging materials like duplex and nickel alloys. The device can access both sides of a dissimilar weld for individual stress measurement.

Applications

Used in petrochemical, energy and power, aerospace, and pharmaceutical industries, particularly where bi-metallic welds are common, such as in pressure vessels, pipelines, and heat exchangers.

Customization

Customization options include specialized probes for curved surfaces or limited access areas.

Case Study

A chemical plant used the PMT-1000 for equipment testing, with results contributing to 10 years of stable operation.

Frequently Asked Questions

Q: Can it measure stress on each side of a dissimilar weld?

A: Yes, it provides stress distribution for each material side separately.

Q: What materials are supported?

A: Materials include stainless steel, duplex, nickel alloys, and more.

Q: Is the indentation visible?

A: Indentations are only a few microns, typically invisible to the naked eye.

Q: Does it affect subsequent NDT tests?

A: No, the micro-indentations do not interfere with non-destructive tests like RT or UT.

Q: Is it suitable for sheet metal welds?

A: Yes, it performs non-distorting tests on sheet metal welds, such as auto body spot and seam welds.

Q: How long is the warranty?

A: Warranty details are not specified; please contact us for information.

Q: Can it be used in confined spaces?

A: Yes, its portable design and flexible power options support confined space operation.
