Problems solved by technology

[0005] Welding to chrome-plated materials is often not as effective as expected, as the areas of the chrome-plated surface that are affected by the heat of the welding are often discolored or even damaged, giving the affected surface a poorer appearance and / or premature corrosion

Embodiment Construction

[0019] refer to Figure 1-5 , a tubular element 102 comprising a workpiece whose outer surface 106 is to be chrome-plated. In order to allow an internal component (not shown) to be welded to the tube 102 without damaging or damaging the chromed surface 106 , the heat sink element 104 is welded to the inner surface of the tube 102 before the outer surface 106 is chromed. The heat sink 104 preferably includes at least two separate layers of material 104a and 104b, which may be welded, bonded or fastened together in any manner so as to dissipate heat generated during the welding process at the surface 112 of the heat sink 104 Provides an extra material thickness to act as a heat sink.

[0020] Outlining the process used, the unplated tube 102 is first welded to the heat sink element 104 at the inner surface 108 of the tube 102 . Next, the surface 106 of the tube 102 is chrome plated. Subsequently, an internal component (not shown) may be welded to the tube 102 through the surf...

Abstract

A method and apparatus for welding a first workpiece to a second workpiece having a first surface to be chrome plated welds a heat sink liner to a second surface of the second workpiece opposite the first surface. The first surface of the second workpiece is them chrome plated. The first workpiece is then welded to the second workpiece at the heat sink, which absorbs a substantial amount of heat generated by the weld before that heat can reach the chrome-plated second surface.

Description

[0001] Cross-references to related applications [0002] This application claims priority to US Patent Application No. 11 / 850,990, filed September 6, 2007, and US Provisional Application No. 60 / 879,240, filed January 8, 2007, which are incorporated herein by reference. technical field [0003] This disclosure relates to welding processes, and more particularly, this disclosure relates to enabling welding to chrome-plated components without negatively affecting the chrome plating. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Welding to chrome-plated materials is often not as effective as expected, as the areas of the chrome-plated surface that are affected by the heat of the welding are often discolored or even damaged, giving the affected surface a poorer appearance and / or premature corrosion. [0006] In the field of welding, there is a need fo...
