Abstract
A welding apparatus is provided for carrying a welding gun across or past a surface for making welds. The apparatus may include one or more rolling components, such as wheels for example, that do not substantially plastically deform as a result of contacting or being in close proximity to recently completed welds or preheated joints and provide adequate traction to move the apparatus across or past the surface. A portion of the contact surface of the rolling component may be configured with a given surface roughness to provide sufficient traction.
Claims12
An apparatus for moving a weld gun across a workpiece to be welded, comprising:
- a housing;
- a welding gun supported by the housing;
- and at least one driven rotatable component rotatably mounted to the housing and having a workpiece contacting outer face that does not include rubber but that includes an abrasive material for providing rolling movement of the apparatus across the workpiece;
- wherein the outer face of the at least one rotatable component does not plastically deform as a result of being exposed to a temperature of at least 500 degrees Fahrenheit and provides traction to move the apparatus across the workpiece during a welding operation.
