Abstract: A tooling fixture is adapted to preserve the dimensional accuracy of critical dimension locating components associated with the fixture. The tooling fixture has a plurality of component locators having a body with at least one surface for accurately constraining at least one component part within the tooling fixture. The surfaces of the component locators are exposed to weld spatter. A spatter resistant coating is applied to the surfaces of the component locators to protect their surfaces from accumulating weld spatter thereby preserving the dimensional repeatability of the tooling fixture and decreasing rework or scrap quantities resulting from the component parts being out of specification.

Abstract: A bi-directional compliant precision linear slide apparatus having a base that supports two side bearing blocks, side rails and an internal air cylinder. The bearing blocks allow for a set of side rails to be moved in a first direction via the introduction or expelling of air to and from the air cylinder. A top rail allows for a top mounting bracket to be moved back and forth in a second direction, and a set of spring loaded plungers facilitate the precise positioning of the top mounting bracket within the top rails prior to bracket engagement to tube. The top mounting bracket is connected to a first component that is to be welded to a second component. Thus, by controlling the precise position of the top mounting bracket, the gap between the two components is controlled thereby affecting the type and quality of weld needed, reducing the amount of the weld time, and reducing the amount of heat introduced into the two components during the welding process.
