A method and system to manufacture workpieces employing a high intensity energy source to create a puddle and at least one resistively heated wire which is heated to at or near its melting temperature and deposited into the puddle as droplets.

Method and system for additive manufacturing using high energy source and hot-wire

A welding electrode suitable for underwater welding is manufactured from a welding rod with a flux layer thereon by forming a protective coating of a waterproofing material at least over this layer and subjecting it to a pressure at least as great as the pressure at a depth of water at which the welding electrode is intended to be used such that the waterproofing material is driven into pores and interstices of the flux to impregnate it Waterproofing materials which do not produce organic residues at welding are preferred, such as liquid sealant with metallic aluminum powder, polyurethane, resins and epoxy-based coatings

Method of manufacturing welding electrode for underwater welding

In the manufacture of hollow weld rods filled with particulate solids such as carbides, the rod ends are sealed with a solid material which has entered into the rod ends between the particles of filler and solidified into a film covering the rod end and filling the interstices of the filler material adjacent the end.

Method of producing tube rods and articles produced therefrom

This invention relates to improved coated filled-tubular hard-surfacing electrodes and methods for manufacturing same. In the manufacture of electrodes of this invention, the ends of electrodes are sealed by dip coating in a liquid or slurry, similar to the flux coating composition.
