How to Reduce Thermal Distortion in FSW of Aluminum
Why Thermal Distortion is Critical in Aluminum Friction Stir Welding When you invest in friction stir welding machines for aluminum components, thermal distortion is one of the most critical challenges you need to address. Excessive heat generated during the welding process can cause warping, dimensional inaccuracies, and residual stresses in the welded parts. For your operations, this translates directly into higher rework rates, increased scrap, and potential delays in delivery schedules. These factors inflate production costs and can affect the reliability and performance of your final products, which is especially important if you supply to aerospace, automotive, shipbuilding, or renewable energy sectors. Aluminum’s high thermal conductivity and low melting point make it particularly sensitive to heat-induced distortion during friction stir welding. Small deviations in temperature control or welding speed can result in misalignment and affect the structural integr...
