6. Laser welding of ultra-high strength steel and a cast magnesium alloy for light-weight design
Sammanfattning : There is a strong industrial need for developing robust and flexible manufacturing methods for future light-weight design. Better performing, environmental friendly vehicles will gain competitive strength from using light weight structures. LÄS MER
7. Fatigue strength of welds in 800 MPa yield strength steels : Effects of weld toe geometry and residual stress
Sammanfattning : Nowadays there is a strong demand for lighter vehicles in order to increase the pay load. Through this the specific fuel consumption is decreased, the amount of greenhouse gases is lowered and the transport economy improved. One possibility to optimize the weight is to make the components from high strength steels and join them by welding. LÄS MER
8. Improving fatigue properties of welded high strength steels
Sammanfattning : In recent years a strong interest has been expressed to produce lighter structures.One possible solution to reduce the weight is to utilize high strength steels and use welding as the joining method. LÄS MER
9. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects
Sammanfattning : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).
