<p>LAMP-BASED SWET WELDING APPARATUS A welding apparatus (20) for welding a workpiece (22) includes a welding-containment box (24) of sufficient size to contain the workpiece (22) at a welding position (26), and a welder disposed within the welding-containment box (24) to he operable on the workpiece (22) at the welding position (26). A heating apparatus (50) includes four heaters (52) disposed within the welding-containment box (24). Each heater (52) has a lamp (54) aimed at the welding position (26), and a heater support (80) upon which the lamp (54) is mounted. The heater support (80) includes a slide (82) that controllably moves the lamp (54) toward and away from the welding position (26). Each lamp (54) preferably includes a light source (56) having a light output (58), and a reflector (60) having a reflecting surface disposed to reflect an incident portion of the light output (58) of the light source (56) toward the welding position (26). The reflector (60) preferably has an aluminum-alloy substrate (64), and a chromium reflecting surface contacting the substrate (64) and disposed to reflect an incident portion of the light output (58) of the light source (56) toward the welding position (26).</p> |
