Compact Through-The-Torch Vision System

Abstract

Changes in gas/tungsten-arc welding torch equipped with through-the-torch vision system make it smaller and more resistant to welding environment. Vision subsystem produces image of higher quality, flow of gas enhanced, and parts replaced quicker and easier. Coaxial series of lenses and optical components provides overhead view of joint and weld puddle real-time control. Designed around miniature high-resolution video camera. Smaller size enables torch to weld joints formerly inaccessible.
