A system and method of welding is provided where at least two welding electrodes are provided to and passed through a single orifice on a single contact tip and a welding waveform is provided to the electrodes through the contact tip to weld simultaneously with both electrodes.

Dual wire welding system and method

The invention described relates generally to a method and apparatus for improving existing bulk wire transfer methodologies and more particularly, to welding wire packages for use as an endless wire container such that the welding wire of multiple containers can be linked together to produce an uninterrupted flow of welding wire to a welding operation by employing a welding wire transfer guide, the guide having an outwardly-facing curvilinear groove, one end of said groove of said welding wire transfer guide positioned along a tangent line running between an outer diameter of the in-process coil of wire and an opposed end of said groove along a tangent line running between an inner diameter of the staged coil of welding wire. The apparatus further includes a magnetically positionable wire guide arm above at least two, preferably each bulk welding wire container.

Bulk wire delivery system

A metal cored electrode used to form a weld metal on a workpiece having improved yield strength, tensile strength and impact toughness by the combination of molybdenum, titanium and boron, the electrode containing at least about 0.001 weight percent boron, at least about 0.05 weight percent molybdenum, at least about 0.005 weight percent titanium and a majority of iron, the above metal alloy system having an average yield strength of at least about 70 ksi and an average tensile strength of at least about 90 ksi.

Metal cored wire

A wire payoff structure includes a plurality of arm members, a first ring, a second ring, and a third ring. The first ring is coupled with each of the arm members. The second ring is coupled with each of the arm members and is spaced radially outwardly from the first ring. The third ring is coupled with each of the arm members and is spaced radially outwardly from the second ring. A portion of each arm member passes beneath the third ring to facilitate contact with an underlying wire stack.

Wire dispensing system including wire payoff structure

A weld wire for storage on a spool of weld wire. The weld wire has a substantially linear cast in the form of an undulating curve that generally lies in a single plane. The undulating curve is a succession of generally semi-circular sections having a generally fixed radius of curvature. The linear cast is formed on the weld wire prior to the weld wire being wound on the spool of weld wire. The linear cast is at least partially retained on the weld wire after the weld wire is unwound from the spool and during the feeding of the weld wire through a welding machine.
