Validation of a Model of Linear Friction Welding of Ti6Al4V by Considering Welds of Different Sizes

A model for the linear friction welding of the alloy Ti6Al4V was tested experimentally. Instrumented welds were carried out on rectilinear geometries of various dimensions, and the thermal profiles, upset rates, in-plane forces and subsequent micro hardness were measured for comparison.

Description
Summary:A model for the linear friction welding of the alloy Ti6Al4V was tested experimentally. Instrumented welds were carried out on rectilinear geometries of various dimensions, and the thermal profiles, upset rates, in-plane forces and subsequent micro hardness were measured for comparison. In particular the effects of weld size perpendicular and parallel to the oscillation were investigated, including a case in which the two sides of the weld had different sizes. The predictions of the model were found to be in good agreement with the experimental results, which provides confirmation that the model is useful for the purposes of design.
