Abstract
A fixture is a mechanism used in manufacturing to hold a work piece, position it correctly with respect to a machine tool, and support it during machining. Widely used in manufacturing, fixtures have a direct impact upon product quality, productivity and cost. Generally, the costs associated with fixture design and manufacture can account for 10%–20% of the total cost of a manufacturing system. Approximately 40% of rejected parts are due to dimensioning errors that are attributed to poor fixturing design. Fixture design work is also tedious and time-consuming. Since titanium has excellent corrosion resistance, high specific tensile strength and good workability, it is widely used for automotive parts, heat-exchanger plates, etc. However, as far as the weld ability of titanium is concerned, there are a number of problems that call for special attention. The reason for this is that when titanium is heated in the welding process, it easily combines with oxygen and nitrogen in the air and its mechanical properties deteriorate. Therefore, during arc welding of titanium in which the metal can be exposed to air, it is necessary to ensure that it is sufficiently shielded.
