16. Experimental and numerical study of deformations and stresses in butt-welded plates
Sammanfattning : Deformations and stresses in butt-welding of plates are studied. Temperatures, strains, residual stresses and change in gap width in front of the heat source are calculated and measured. In particular, the change in gap width in front of the heat source during welding and residual stresses after welding are studied. LÄS MER
17. Stress fields induced by moving heat sources in butt welding of plates
Sammanfattning : .... LÄS MER
18. Inductive measurement of narrow gaps for high precision welding of square butt joints
Sammanfattning : A recent method in aero engine production is to fabricate components from smaller pieces, rather than machining them from large castings. This has made laser beam welding popular, offering high precision with low heat input and distortion, but also high productivity. LÄS MER
19. Continuous Welded Railway Rails: Residual Stress Analyses, Fatigue Assessments and Experiments
Sammanfattning : Railway rails are today often continuously welded. This type of joint generally requires less maintenance than is needed for the bolted joints. It has also reduced wheel damage and made the ride more comfortable. However, these joints are subject to damage. LÄS MER
20. Deformations and stresses in welded pipes : numerical and experimental investigation
Sammanfattning : In this dissertation, deformations and stresses in welded pipes have been studied both numerically and experimentally. The aim of this work has been to investigate and verify finite element models for simulation of the fabrications of two types of pipe joints. LÄS MER
