Abstract:
An electric arc welding wire having an outer cylindrical surface and an electrically conductive layer on the surface wherein the layer comprises an alloy of copper with the copper content being about 60% to about 90% by weight of said alloy. Furthermore, the layer can be made thin with a thickness of less than about 0.50 microns while using essentially pure copper.
Abstract:
A burner assembly comprising a burner element (8) at which gas is combusted. A valve (2) allows selective release of gas from a source into an expandable space (4) when the valve is opened. The space is expanadable up to a fixed volume (3) against the action of a restoring means. The space is arranged to contract under the action of the restoring means to force gas out of the space and to the burner element.
Abstract:
A granular flux formulated to reduce copper cracking in a weld bead. The granular flux forms a slag during a welding process that inhibits or prevents migration of molten copper migration through the slag.
Abstract:
Disclosed are electrode compositions that produce high strength and/or high impact toughness weld deposits that exhibit reduced potential for hydrogen cracking. Also disclosed are the compositions of various high strength and/or high impact toughness weld deposits that exhibit reduced potentials for hydrogen cracking. Related methods of arc welding the noted electrodes are also disclosed.
Abstract:
Large diameter weld wire and methods for forming a large diameter weld wire are provided, in which weld wire is formed and a sinusoidal shape memory is imparted on the wire to enhance feedability and ease of withdrawal from a storage spool or container.
Abstract:
Disclosed is a composition consisting of beta-glucan (1,3), (1,4) β-D Glucan), plant sterols and a hydrocolloid. A natural way to help lower blood serum cholesterol levels to a consumer and or patient with the effective amount of disclosed composition. For use in foods, beverages, dietary supplement products and medical foods.
Abstract:
A welding flux formulated for pipe welding or one-side welding applications including a gas releasing agent, a high melting compound and a low melting compound. The welding flux is particularly formulated for limited pass welding applications which exhibit high impact strength, good slag detachability, low weld metal hydrogen and nitrogen absorption, and facilitates in the formation of smooth and consistent weld beads.
