KTH Royal Institute of Technology is looking for a doctoral student to join the WELD-AID project, a Vinnova-funded initiative focused on improving quality assurance in welded structures through AI and digitalization.

In collaboration with industry partners, the project aims to enhance Sweden’s position in welded product design and manufacturing by integrating machine learning (ML) methods to detect weld imperfections and optimize welding processes.

As a doctoral student, you will focus on developing hybrid AI models, including:

• Convolutional Neural Networks (CNNs) for weld localization
• Physics-Informed Neural Networks (PINNs) for weld quality assessment and service life prediction

This position is well-suited for candidates interested in applying AI to industrial challenges and advancing welding technology.

Supervision: Professor Joakim Jaldén (Division of Information Science and Engineering) will be the main doctoral supervisor, with support from Professor Zuheir Barsoum (Division of Material and Structural Mechanics) as co-supervisor.

What we offer

• The possibility to study in a dynamic and international research environment in collaboration with industries and prominent universities from all over the world.
• A workplace with many employee benefits and monthly salary according to KTH’s Doctoral student salary agreement.
• A postgraduate education at an institution that is active and supportive in matters pertaining to working conditions, gender equality and diversity as well as study environment.
• Help to relocate and be settled in Sweden and at KTH.

Admission requirements

To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

• passed a second cycle degree (for example a master’s degree), or
• completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
• acquired, in some other way within or outside the country, substantially equivalent knowledge

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6.

Selection

In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

• independently pursue his or her work
• collaborate with others,
• have a professional approach and
• analyse and work with complex issues.

A successful candidate should have documented good practical and theoretical knowledge of state-of-the-art machine learning methods including deep neural networks and be a proficient programmer, particularly in Python whereas knowledge of lower-level programming languages (C/C++, CUDA) will be considered meritorious.

Knowledge of structural mechanics or materials science is not required (for this particular doctoral position) but will also be considered a merit.

It is advantageous if the candidate can express him- or herself well in Swedish in speech and writing, as this facilitates in the daily work and most of all during cooperation with the Swedish industry. 

After the qualification requirements, great emphasis will be placed on personal skills.

Target degree: Doctoral degree

Information regarding admission and employment

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ‘ time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
