Abstract:
A process, for locating a welding energy director, for effective welding together of multiple workpieces at an area of the director. The director includes positioning a workpiece arrangement in preparation to make approaches, for locating the director, wherein the workpiece arrangement includes a proximate workpiece of the multiple workpieces, a distal workpiece, and the welding director positioned therebetween. The process also includes performing a sub-routine comprising moving a locating implement toward the proximate workpiece. The routine also includes determining whether a push-back force, being received at the locating implement from the workpiece, indicates that the locating implement has been lowered to a local terminal point. The routine includes relocating, in response to a negative result, the implement for repeating until a positive result, and determining, in response to the positive results in the location determination, that the director is located directly beneath an area corresponding to the positive result.
