Abstract
A portable multi-axis load confirmation tool having a rotating ball on the end thereof follows a three-dimensional weld program path therewith. The ball reacts to an internal load cell for verifying weld program path dynamics before an actual program is run with friction stir welding tools. The load cell is connected to instrumentation electronics converting a load cell signal to a digital readout and comparing the load cell signal to weld program load requirements. The tool integrates into a tool holder loaded on a friction stir welding spindle for simulating an actual friction stir welding tool.
