A method and system to weld or join workpieces employing a high intensity energy source to create a weld puddle and at least one resistive filler wire which is heated to at or near its melting temperature and deposited into the weld puddle.

Method and system to start and use combination filler wire feed and high intensity energy source for welding

A welding electrode hybrid laser arc welding is provided which is either a solid or metal core electrode. The electrode contains at least carbon, manganese, silicon, sulfur and phosphorus. The electrode has is no more than 0.02% carbon, manganese in the range of 0.6 to 1.2%, silicon in the range of 0.3 to 0.6%, no more than 0.01% sulfur, and no more than 0.01% phosphorus in % by weight of the electrode.

Electrode for GMAW hybrid laser arc welding

A metal core electrode used to form weld deposits having improved slag forming properties with respect to reduced accumulation of slag in toes of the weld bead. The metal cored electrode includes a metal rod and a fill composition. The electrode includes a slag-modifying additive that contains metallic indium and/or one or more indium compounds.

The method of optimizing performance of a weld includes determining a set of specified mechanical properties, such as hardness or toughness for the weld, selecting a base metal material, selecting a welding process and welding process conditions, and selecting a weld metal material. The weld metal material and/or the base metal material may be selected by determining a characterization of the weld or base metal material, the characterization including performing a thermal-mechanical simulation of the metal materials and determining the properties of the metals produced by the thermal-mechanical simulation, and subsequently correlating the characterization of the metal materials with the set of specified mechanical properties and the welding process conditions. The method may also include producing said weld having said set of mechanical properties.

Method for optimizing weld performance

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 feeding lubricant for use on a welding electrode comprises about 10 to 40 wt. % of at least one soap-based lubricant, about 40 to 90 wt. % of at least one solid particulate lubricant selected from MoS, WS, ZnO, graphite and PTFE and up to 20 wt. % of at least one optional additional particulate lubricant ingredient.

Feeding lubricant for cored welding electrode

A wire containment structure includes a container and a bag. The container includes a sidewall that at least partially defines a container receptacle. The sidewall defines a first handle aperture and a second handle aperture. The bag is configured to entirely support a wire stack. The bag is disposed at least partially within the container receptacle and comprises a body, a first handle, and a second handle. The body defines a wire receptacle. The first handle is coupled with the body and is routed through the first handle aperture. The second handle is coupled with the body and is routed through the second handle aperture.
