ABSTRACT:
A relatively simple and inexpensive apparatus and method for providing high quality and aesthetically pleasing continuous resistance welded hollow metal articles at constant speed comprises an article workpiece conveying guide means for guiding the article workpiece through a welding means under controlled, stable, vibration free conditions in a predetermined path. The path has linear and non-linear portions. A sensor interactively connected to a programmable controller which functions to move the workpiece quickly and accurately through the welding means under stable conditions at a high uniform rate of speed. A first guide provides a weld edge reference guide, and a simple pivotal tracking system provides a weld path guide during non-linear travel of the workpiece. The tracking system exerts its force on the workpiece generally through the center of percussion of the article workpiece whereby no vibration is imparted by the force to the workpiece.
