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 bag pack comprises a plurality of easy open handle bags. The bags are easy to open because the exterior surfaces of the bags are cold-welded together so that when one bag is pulled from the pack, the adjacent next bag is at least partly open. The external surfaces of the bags are not welded to the internal surfaces of the bags during the pressure welding process, because the material that forms the external surface of the bag is treated with a corona discharge, which renders the external surface more susceptible to cold weldings. Optionally a static charge is induced on the bags so that each bag is at a different voltage than the adjacent bags so the bags attract each other, and the panels of each individual bag repel each other, to contribute to the easy open feature.
