Abstract
A housing for an underwater processing device, for example, welding, includes a welding head movable laterally relative to the housing and the direction of the weld. At opposite ends, gates are provided having arcuate convex surfaces forming edge seals for engaging in the groove of the work surface. In one form, the gates are linearly slidable and biased in a direction away from the housing. In another form, the gates are pivotally mounted for engaging in the grooves. In both cases, the compliant seal about the margin of the housing, together with the arcuate seal of the gates, maintains a substantially water-free area within the housing to enable processing.
