The exposed metal tip of the strike end of an SMAW welding electrode is covered with a protective coating formed from a binder and metal particles. Because metal particles rather than graphite particles are used to provide electrical conductivity to this protective coating, flare-up of the arc when initially struck is eliminated substantially completely. In addition, the potential for weld porosity problems is also eliminated, because the metal particles of the inventive electrode do not produce COas a reaction by-product which can ultimately lead to improper welding technique.

Stick electrode

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.

Electric arc welding wire

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.

Welding flux

A method and apparatus of comparing two or more welding flux systems to determine which flux system results in the smallest incidence of undercut about a weld bead in an inner diameter of a pipe.
