Abstract
A seam welding apparatus is provided which automatically senses and adjusts the position of a welding torch in triaxial X, Y and Z directions and controls the position so as to maintain a predetermined position of the torch with respect to an irregularly shaped workpiece such as elliptical shapes. The apparatus also provides for continuously sensing and adjusting the surface speed of the workpiece so as to maintain a predetermined constant speed. A slope/speed sensor is also provided for sensing surface speed and slope of the workpiece. A method of continuously sensing triaxial position and surface speed of the workpiece adjacent the torch and adjusting the position of the torch and speed of the workpiece so as to maintain a desired position and speed is also provided.
Claims11
A slope/speed sensor for sensing slope and speed of an object comprising:
- a base,
- a mounting member,
- pivot means pivotally attaching said base to said mounting member, and
- slope sensing means on said base for contacting a workpiece and causing said base to be pivoted relative to said mounting member in proportion to the slope of the workpiece, and
- tachometer means for sensing and transforming surface speed of a workpiece into an electrical characteristic proportional to the surface speed.
