PhD Researcher: Computational Weld Mechanics

LUT University; Lappeenranta; On-site; EUR 31,000 - 38,000; Full time

Job summary

LUT University seeks a doctoral researcher to join its Welding Technology Unit and the Steel Structures Unit in Lappeenranta, Finland. The role focuses on computational weld mechanics to analyse heat-affected zones in welded high‑strength steels and to develop predictive models for design of welded structures.

Starts December 2026 with a flexible schedule and on-site work. The position is funded for an initial term of one year and may be extended up to four years based on progress.

Qualifications

• Master’s degree in a relevant field (mechanical/materials/welding/computational mechanics) and ability to complete doctoral studies.
• Solid background in numerical modelling, materials science, solid mechanics, finite element methods, programming, and/or welding technology.
• Proficiency in English, written and spoken.
• Willingness to travel within Finland and to international conferences.

Responsibilities

• Analyze local heat-affected zone (HAZ) behaviour in welded high-strength steels using computational weld mechanics and phase-transformation modelling.
• Develop and validate predictive models for performance-driven design of welded structures.
• Conduct experimental characterisation of welded joints using microstructural, thermal and mechanical measurements.
• Collaborate with international research partners and communicate findings.
• Travel within Finland and to international conferences as required.
