Measurement of Quantity of Heat in Friction Welding

Abstract

In order to measure the heat input (quantity of heat) generated during friction welding, a new type calorimeter of acryl resin was developed, and applied to friction welding of a stainless steel. The heat input measured during friction welding was in good agreement with the values calculated from the measured values of friction torque, burn-off length, rotation speed and pressure. Being classified into friction and deformation heat inputs, the friction heat input was much greater than the deformation heat input through the friction and upset stages.
