The vision and goals of the division of Welding technology
Our vision is to become the most distinguished research group on welding and associated technologies in the Nordic countries and well-known globally in our dedication.
Our goals are to fundamentally study and improve the knowledge on welding processes and its corresponding influence on the materials as well as to educate students.
Enabling welding of “hard-to-weld” materials to pave the way for a more sustainable society Offshore

Some examples of projects…
• Laser beam energy sourceImplement beam energy distribution varying in time and space -> study effect on melt, HAZ (Adopt)
Process physics – simulation (development & application)
• Laser/material interractionDevelop & implement laser metalinteraction model including wire-> study shadowing effect& effect of metal transfer on melt,
HAZ (T-SAMw)
• Melt pool thermal convection & surface derfomation
Metalwire
Improve model efficiency for tracking of surface deformation to reduce CPU, improve accuracy (ex. resolve pore entrapment for small enough pores)-> study melt, HAZ combining heat source,
metal transfer, melt flow, pore formation (T-SAMw)Provide process knowledge (ex. T-distribution)
- to link process & deposited material properties (T-SAMw)- as input to control the process (T-SAMw)

Synergy for Additive Manufacturing using laser beam heat source and wire - SAMw
Core question: how to tailor the performance (functionality and integrity) of high strength steel components through laser and arcadditive manufacturing?
TAiloring of high PERformance parts through laser and arc additive manufacturing TECHhnologies: TAPERTECH
Objective: To develop the knowledge needed for industrial application of the technologies embraced by DED-AM (Directed EnergyDeposition Additive Manufacturing), especially using LMDp (Laser Metal Deposition with Powder) and WAAM (Wire + Arc AdditiveManufacturing) processes, to tailor the performance of high strength steel components.
Duration: September 2019 to August 2022
Development strategy: based on the elements of the cluster “Process-Automation-Materials-Simulation-Mechanical Characterization”, 4subprojects are organized in an integrated and synergic way in order to understand the link between different material wire deposition,microstructure evolution along the thermal history and occurrence of imperfection to develop a robust process from a functionalcomponent point of view.Subproject AMMet-Tapertech (Additive Manufacturing Metallurgy of High Strength Steels)Subproject AMSim-Tapertech (Additive Manufacturing Modelling and SimulationSubproject AMProc-Tapertech (Additive Manufacturing Process Development and Control)Subproject AMPMech-Tapertech (Additive Manufacturing Mechanical Characterization)

Industrial partners:
• Need from Industry: Better understanding of mechanisms and welding recommendations for avoiding embrittlement in welds of highly alloyed duplex stainless steel. Cost effective methods for microstructure and property characterization and mapping.
• Research questions: How do spinodal decomposition resulting in embrittlement depend on composition and thermal cycles experienced during welding and/or heat treatment for duplex stainless steels and weld metals.
• Goal: Defining welding parameter window ensuring 475°C embrittlement is avoided. Production of TTT, CCT and property diagrams for base material and weld metal.
• Internal resources: Vahid Hosseini, Kjell Hurtig, Sten Wessman + ref. group Robert Pederson + Asun Valiente
Project name: Avoiding 475°C embrittlement in welded highly alloyed duplex stainless steels
