1st part - literature survey
This part is a literature survey on
• Typical defects in laser welding of extruded aluminium and remedies believed to minimize risks for the defect formation. Specifically lack of fusion and cracks.
• Joint design suitable for laser welding (configuration, preparation and position). This part may include modelling and simulations.
• Principles to minimize deformation and residual stresses.
• How to do a productivity calculation.
2nd part - experimental work
This is an experimental part performed mainly at Swerea KIMAB
• Propose a simplified test object for welding instead of the full component.
• Design different joint configurations (including sensitive parameters or critical dimensional deviations) to evaluate the most suitable for laser welding (considering risk for deformation and defects).
• Perform/Participate in laser welding.
• Evaluate welds mainly with optical microscopy from polished and etched cross sections and measure deformation (preferably with 3D scanning technique).
• Perform/Participate in laser welding of a product made of aluminum extrusions. Asses the welding sequence and how this will affect the deformation.
• Perform leakage test of a product.
• Make a productivity calculation.
