A cable-type welding wire provided in the present application, includes a central welding wire and n peripheral welding wires arranged so as to be spirally wound on the central welding wire, with each of the peripheral welding wires having a diameter of d.sub.peripheral, and adjacent peripheral welding wires being arranged to be tangential to each other, wherein, the peripheral welding wires have a lay length of T, which satisfies the equation of T=m?(d.sub.peripheral+d.sub.central)/2, where m is a multiple of the lay length, d.sub.peripheral is a diameter of the peripheral welding wire, d.sub.central is a diameter of the central welding wire, and 3.2?m<20. This application can obtain a smaller penetration depth when the welding parameters remain constant due to a small multiple of the lay length of the cable-type welding wire, and can further reduce welding arcing current.

The disclosed technology generally relates to welding, and more particularly to a consumable welding wire for metal arc welding, and a method and a system for metal arc welding using the consumable welding wire. In one aspect, a method of arc welding includes providing a welding wire comprising one or more alkaline earth metal elements. The method additionally includes applying power to the welding wire to generate a plasma arc sufficient to melt the welding wire. The method further includes depositing molten droplets formed by melting the welding wire onto a workpiece at a high deposition rate while regulating to maintain a substantially constant power delivered to the plasma arc.

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.

A kind of stainless steel auger braid welding material and its manufacturing method are disclosed in the invention, involving the field of welding technique. The stainless steel auger braid welding material consists of core wires and several steel tendons, wherein the said welding wire is of a round-bar shape; the said steel tendons are wrapped on the external surface of the said core wire along the axial line and stranded around the circumference of the said core wire, and each steel tendon shall be stranded by winding several fine wires. For the stainless steel auger braid welding material adopted in the invention, its melting rate is fast.

Laser cladding systems include a metal-filled wire comprising a metal shell surrounding a metal-filled core, wherein the metal-filled core comprises at least one of a powder metal or a fine wire metal, and, a laser that produces a laser beam directed onto at least a portion of a tip of the metal-filled wire to melt the metal shell and metal-filled core to produce a molten pool for depositing on a substrate.

A method of forming a metal workpiece is disclosed herein. The method includes applying a concentrated energy to a core wire to form melted material, and forming a metallic component from the melted material based on the concentrated energy. The core wire comprises at least two internal compartments. A first internal compartment of the at least two internal compartments comprises a first powdered material. A second internal compartment of the at least two internal compartments comprises a second powdered material. The electric current heats the core wire, the first powdered material, and the second powdered material to generate the melted material.
