    Sammanfattning : Manufacturing of aero engine components requires attention to residual stress and final shape of the product in order to meet high quality product standards.This sets very high demands on involved manufacturing steps to meet design requirements. LÄS MER

  5. 4. Simulation of robot paths and heat effects in welding

    Författare :Mikael Ericsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsteknik; Welding; Automation; robotics; Off-line programming; Robotics; Automatiska system; Production technology; control engineering; Finite Element Analysis; reglerteknik; robotteknik;

    Sammanfattning : The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. LÄS MER

  7. 5. The Influence of Composition and Hot Processes on Heat Affected Zone and Weld Metal Behavior and Mechnacal Properties of Ti Grade 5 and Stainless Steel

    Författare :Esa Kivineva; KTH; []
    Nyckelord :Stainless steel; Duplex stainless steel; Titanium Grade 5; Ti-6Al-4V; Microstructure; Mecjhanical properties; Welding; Welding simulation;

    Sammanfattning : This thesis discusses on results of experiments carried outwith austenitic, duplex and super duplex stainless steels andTi-6Al-4V. In these it has been seen that the heat cycle duringwelding or weld simulation has a great effect on the propertiesof thematerials. LÄS MER
