An adapter for a plasma arc torch comprising a torch body is provided. The adapter includes a body defining a longitudinal axis between a proximal end and a distal end and at least one protruding portion extending from the proximal end of the body. The at least one protruding portion is configured to be inserted into a cavity of the torch body to physically engage a switch inside of the cavity. The engagement of the switch is adapted to indicate installation of a consumable component in the plasma arc torch.

An example welding-type system includes: processing circuitry; and a machine readable storage medium comprising a machine readable instruction, when executed by the processing circuitry, cause the processing circuitry to: control a first switch to disconnect a motor circuit from a motor power source, the motor circuit comprising a wire feed motor and a second switch; control the second switch to permit current to flow while the first switch disconnects the motor circuit from the motor power source during a test period; and in response to feedback indicative of a current through the motor circuit while the first switch is open and the second switch is closed, detecting a fault condition associated with the motor circuit.

A method of providing a tool with a conformal cooling passage includes rough machining a cavity generally corresponding to a manufactured part shape using CAD data. Conformal cooling slots are cut in the cavity using the CAD data. The conformal cooling slots are welded shut using the CAD data to provide conformal cooling passages. A class A surface is machined over the conformal cooling passage and corresponds to a finished manufactured part shape using the CAD data.

The invention relates to a method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned between at least two metallic layers. At least one of the metal layers is shaped into a three dimensional layer, and the metal layers are in direct mechanical contact to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions in a subsequent manufacturing process.

The invention relates to a wear-resistant roller (1) for crushing of particulate material, such as crude ore for use in the cement or minerals industry comprising a roller body (2), a wear surface (3) on the roller body (2) having an axial extension in an axial direction of the roller and a radial extension in a radial direction of the roller, the wear surface (3) comprising a primary fraction of matrix material and a secondary fraction of hard phase material suspended in the matrix material, wherein the secondary fraction of hard phase material in a central portion of the wear surface is higher than the secondary fraction of hard phase material in a peripheral portion of the wear surface seen in the axial direction of the roller. Also the invention relates to a method of forming such a wear surface on a roller body.

An arc welding apparatus and corresponding method includes a torch, a non-consumable electrode and a consumable electrode both disposed within the torch, a wire feeder configured to feed the consumable electrode in a vicinity of the non-consumable electrode, a first power source and a second power source that provide independent current, respectively, to the non-consumable electrode and the consumable electrode, and a weld process controller to control outputs of the first power source and the second power source such that a concentrated arc is formed, as a heat source, between the non-consumable electrode and a workpiece, and an inter-electrode arc is formed between the consumable electrode and the non-consumable electrode to melt the consumable electrode. The approach is characterized by low heat input, low distortion, low spatter, and the relative high speed or high deposition of laser and laser-MIG hybrid and other forms of multi-wire/multi-electrode welding, cladding, and additive manufacturing.
