Overview of PWC-Compass: Software Tool for Modeling and Prediction of Preferential Weld Corrosion

PWC-Compass is the only device and OS independent software tool on the market for the modeling and prediction of preferential weld corrosion (PWC). Design engineers, welding engineers, engineering consultants, maintenance and inspection personnel can quickly assess the impact of filler metal chemistry on the risk of preferential weld corrosion anytime, anywhere, on any device running any OS without the need to install or download anything (Figure 1).

Figure 1 PWC-Compass Models and Predicts the Risk of Preferential Weld Corrosion.

Outputs from PCW-Compass include the following:

1. The risk of preferential weld corrosion: no risk; low risk, moderate risk, high risk

2. The location of corrosion: weld metal; HAZ/parent metal

3. The anode

4. The type of corrosion expected: general corrosion; localized corrosion

5. Comments on reducing the risk of PWC

Figure 2 PWC-Compass Models and Predicts Preferential Weld Corrosion in Carbon Steels, Low Alloy Steels Stainless Steels, and Nickel Alloys.

The powerful applications of PWC-Compass are truly unlimited in engineering design, filler metal selection and optimization, materials compatibility assessment, trouble-shooting process-related issues and failure analysis of components and systems. If the risk of PWC is high, the corrosion rate of the weld or the parent metal in various service environments can be accurately predicted with the following specialized corrosion modeling and prediction software (click the title to view detailed features and application examples):
