ABSTRACT:
Welding apparatus is provided for moving a welding tool in a controlled path at a controlled speed relative to a workpiece to produce a uniform weld bead. The apparatus includes a base carrying a workpiece support and a drive and control housing located behind the workpiece support. A welding tool mounting member is located under the drive and control housing and extends toward and over the workpiece support. A driven member in the drive and control housing is connected through a slot therein with the welding tool mounting member. The mounting member is guided by the driven member for movement in a linear path toward and away from the workpiece support to move a welding tool carried thereby back and forth over the workpiece support. Drive means moves the driven member and causes the mounting member to travel at a controlled, constant rate of movement toward said housing and away from the workpiece support. The mounting member has a handle to enable an operator to move the mounting member away from the housing back to a starting point over the workpiece support.
