An ultrasonic machine tool comprises a stand that can be attached to a base plate. The machine furthermore has a vibration generator by means of which a working member can be driven, wherein the vibration generator is borne by a slide displaceably guided in the longitudinal direction of the stand. The slide is in turn borne by a linear drive attached to the stand. The vibration generator is located in the alignment of the adjustment path of the linear drive.

A welding system for applying a weld to a workpiece, the welding system including a frame, a welding torch mounted on the frame, the welding torch including an electrode; a wire guide adapted to direct a wire toward the electrode; a wire alignment assembly including a fixture frame having a wire guide holder mounted thereon, the wire guide being supported on the wire guide holder, wherein the wire alignment assembly includes multiple degrees of freedom for adjusting the position of the wire guide as needed for a given welding operation.

In various examples, a computer-implemented method of generating instructions for a welding robot. The computer-implemented method comprises identifying an expected position of a candidate seam on a part to be welded based on a Computer Aided Design (CAD) model of the part, scanning a workspace containing the part to produce a representation of the part, identifying the candidate seam on the part based on the representation of the part and the expected position of the candidate seam, determining an actual position of the candidate seam, and generating welding instructions for the welding robot based at least in part on the actual position of the candidate seam.

Provided are a welding apparatus and a method, including a welding torch, a wire nozzle, a support stand that supports the welding torch and the wire nozzle with a predetermined distance therebetween, and a first support mechanism that supports the support stand so that the support stand is rotatable around a first support axis that is along a direction in which the welding torch and the wire nozzle are arranged.

An identifier management method is executed by a welding system. The identifier management method includes: acquiring information on identifiers of a plurality of original workpieces; selecting, according to a predetermined rule, any one of the identifiers of the plurality of original workpieces to be adopted based on completion of execution of a welding process using the plurality of original workpieces by the welding system; and setting the any one of identifiers of the plurality of original workpieces, which has been selected, as an identifier of the welded workpiece generated in the welding process.

A welding system configured to weld a workpiece by using a welding device and a positioner includes a control device configured to control the welding device and the positioner. The positioner includes a workpiece position setting mechanism having reference position information, and at least one holding mechanism configured to hold the workpiece. The control device includes a positioner position calculation means for calculating a position of the holding mechanism when holding the workpiece based on the reference position information provided from the workpiece position setting mechanism and workpiece information inputted into the control device in advance.

This method for acquiring weld pass information pertaining to execution conditions for a weld pass for welding two workpieces, which are to be welded by the welding robot, includes: a step in which a weld pass for welding the two workpieces is extracted from 3D CAD data; a step in which a wall determination model having a predetermined 3D shape is prepared; a step in which the wall determination model is positioned in the direction extending towards the outside of the weld pass, the end of welding which is the starting point or ending point of the weld pass serving as a reference; and a step in which, for the positioned wall determination model, a determination is made as to whether there is interference from a wall surface demarcated by another member different from the two workpieces.

An example diagnosis system determines a state of a target device that includes a work apparatus. The diagnosis system includes circuitry that is configured to acquire first data generated in response to operating the work apparatus at a first pressure, configured to acquire second data generated in response to operating the work apparatus at a second pressure, configured to calculate a feature quantity indicating a relation between the first data and the second data, and configured to determine the state of the target device based on the feature quantity.
