<p>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.</p>
