Weld Joint Quality Process Wins Prize

Thomas Stenberg, a PhD student in the department of Aeronautical and Vehicle Engineering at KTH Royal Institute of Technology (Stockholm, Sweden) won the Swedish Steel Prize University Challenge 2015 with a quality assurance method for weld joints. “Good weld quality affects the fatigue strength of components, especially important for the use of high-strength steel. The winning application is a new method for assuring the high quality in the form of longer fatigue life of weld joints,” says Gregoire Parenty, the chairman of the jury and executive vice president and the head of market development SSAB (Svenskt Stål AB; Stockholm, Sweden).

Stenberg’s work will contribute to the development of software and measuring equipment for use in future industrial production lines. The Swedish Steel Prize University Challenge is an international prize aimed at inspiring students to learn about steel and how to design and manufacture in high-strength steel. It can be won by a team of students at any university who has come up with an idea for a product that includes high-strength steels, construction or wear-resistant steels, or a suggestion for a method that expands the field of application for these steels.

The prize is being awarded for the fourth consecutive year. The winner receives a diploma and a meeting with one SSAB specialist for a day.
