there is an equation that has been developed with abregast et al for calculating temperature in FSW and FSP processes that travel speed of process is also kept in calculation. As the FSSW process do not have travel speed is ther any other equation for calculating peak temperature during FSSW?
Please suggest article.
Heat generation
Friction stir welding requires average heat input per unit area and time relation which is given by following formula
Where the time relation is given by
Where N= revolution per minute
now calculate sliding contact and sticking contact heat generation values and add them both to calculate total heat generation
Dear Barabi
Nice day.
I suggest you to read this thesis (Experimental and Numerical Study of High-Speed Friction Stir Spot Welding of Advanced High-Strength Steel by Utsab Bikram Karki ). Mr. Karki used thermocouples to study the temperature in the FSSW . His model predicted welding temperatures to within 4% of the experiments. The welding loads were significantly over predicted. Comparison with a 3D model of FSSW showed that frictional heating and the proportion of total heat generated by friction were similar. The position of the joint interface was reasonably well predicted compared to experiment. This thesis is available in research gate and I hope it will help you.
Best regards
