摘要： 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.

摘要： A dual-wire hybrid welding system includes a hybrid welding apparatus having laser, electric arc welder and second wire feeding device. Electric arc welder includes first wire feeding device for feeding first wire. Second wire feeding device is arranged and disposed to feed a second wire to electric arc welder. Laser and electric arc welder are arranged and disposed to direct energy toward at least two adjacent components along a joint and first wire is a consumable electrode fed into joint to establish molten pool generated by both laser and arc welder with first wire. Second wire is fed to molten pool to form a common molten pool. Common molten pool is operable to provide a full penetration weld with less total heat input to join the at least two adjacent components without cracking the components at a high constant weld speed.

摘要： The invention relates to a method of gas metal arc welding in which an electric arc burns in a shield gas environment during welding for production of a weld along a welding path between at least one workpiece to be welded and a melting wire electrode (1) that is in particular continuously fed to the at least one workpiece. At the starting end of the weld to be produced, chronologically before ignition of the electric arc between the at least one workpiece and the wire electrode (1), a nonconsumable electrode (2) is moved toward the at least one workpiece. Between the at least one workpiece and the nonconsumable electrode (2), in a shield gas environment an electric arc is ignited that locally preheats the at least one workpiece at the starting ending end of the weld to be produced. After the preheating the nonconsumable electrode (2) is removed from the at least one workpiece and after removal of the nonconsumable electrode (2) the electric arc is ignited between the at least one workpiece and the wire electrode. The invention further relates to a torch head for carrying out the method.

摘要： A welding device has a central unit and a welding torch unit, which can be connected to the central unit. The central unit includes at least one welding current source for providing electric current needed to operate the welding torch unit and includes a control unit. The welding torch unit includes at least a first welding torch with a first welding wire and a second welding torch with a second welding wire. The control unit is configured to carry out a starting process in such a way that firstly a first arc ignition takes place at one of the two welding torches and after a waiting time since the first arc ignition has passed, a second arc ignition takes place at the other of the two welding torches, which until then was not ignited.

摘要： A tandem arc welding device in which the welding conditions and a program describing contents of operation are treated as independent to each other. It handles the welding conditions altogether simply as those parameters for the fore-going welding and those parameters for the hind-going welding. By so doing, a program can be produced without taking which of the two welders will become fore-going into consideration. Furthermore, a program and welding conditions thus provided offer superior re-usability and reproducibility to the tandem arc welding.

The first power supply provides the first welding current via a torch to a first wire to create an arc between the first wire and the workpiece. The system also includes a first wire feeder that feeds the first wire to the torch, and a second wire feeder that feeds a second wire to a contact tube. The system further includes a second power supply that outputs a heating current during a first mode of operation and a second welding current during a second mode of operation. The system also includes a controller that switches the second power supply from the first mode of operation to the second mode of operation to create a second (trailing) arc.
