Button attachment method for saw torque sensor

摘要

A method for joining dissimilar materials of sensor button for measuring torque is illustrated. The dissimilar materials can be welded together by laser welding. The parts can be cleaned and held together firmly by a fixture and welded with established machine parameters. The method of micro-crack free weld joint can give a robust joint for the life time of the automotive which mandate for the function of torque sensor to facilitate the positive strain transfer from the parent material.
