Abstract
A method for manufacturing a trailer wall includes welding wall members together on a work surface while pressing the wall members with a rotatable roller toward the work surface and cooling the wall members adjacent points of welding there between to reduce bowing of the wall members related to heat created in the wall members by the welding. A related apparatus includes a movable welding unit having a welding tip for welding a pair of wall members together at a plurality of locations while on a work surface. A rotatable roller is pivotally mounted on the welding unit for applying pressure to the wall members toward the work surface adjacent the welding tip while rolling along the wall members. A cooling unit moves liquid or gas coolant to provide the cooling effect. Preferably, the wall members are hollow shiplap panels and the coolant passes through the hollow panels.
