Thermographic Analysis for Non-destructive Testing of Joints

Dear Colleagues,

Infrared thermography (IRT) is an advanced technology used in various fields to detect defects and anomalies in products and materials. Active thermography involves the intentional heating of a component by external sources to generate thermal changes, and the detection of these changes based on the infrared radiation emitted by the object enables the identification of internal problems or defects in materials.

Active thermography is an emerging technology with the potential for the joint inspections of industrial components. Its cost-effectiveness and versatility make it a promising choice for improving the joint quality with minimal cost and waste.

In the field of welding inspection, where it is critical to ensure the quality and integrity of welded connections, the conventional technologies used to assess joint quality involve destructive testing techniques that are expensive and time-consuming. As a result, alternative non-destructive testing (NDT) approaches, like eddy current testing, magnetic particle testing, radiographic testing, and ultrasonic testing, have been standardized and implemented. On the other hand, there are no specific standards for the application of NDT-based thermography testing. This Special Issue aims to collect the most recent results in the non-destructive testing based on thermographic analysis.

Contributions can include the following:

• Case study applications to demonstrate the relevance of technology based on active thermography in the industrial field and to assess its cost and sustainability benefits;
• Methods of analyzing heat maps obtained using thermographic analysis for identifying defects/anomalies in jointed components for quality testing;
• Applications of active thermography for the inspection of joints of different materials, shapes, and sizes;
• Comparative studies of active thermography with other non-destructive techniques already applied at the industrial level.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Manufacturing and Materials Processing is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
