The system has a first pair of adjustable reference points on a left side of a mobile welding apparatus. The system has a second pair of adjustable reference points on the right side of the welding apparatus. The system has a first lifting mechanism positioned between the first pair of adjustable reference points and a second lifting mechanism positioned between the second pair of adjustable reference points. The welding line is positioned between the first and second pair of adjustable reference points and is the location of the weld. The system allows for comparatively shorter inserts than previously utilized.

A reciprocating welding device using a microcontroller to control a stepper motor to control a welding head for the stationary welding of a workpiece, the microcontroller allowing for adjustment of the welding head reciprocating stroke speed, the width of each stroke, and a pause from 0-1 second at the sides to control the wash of the welding edges, having a manipulator, the welding head and the oscillator contained in a single unit and provided on a multiple adjustment portable stand.

Systems and methods suitable for shaping and cutting materials. Such a system includes first and second carriage units that are independently operable to travel in a travel direction parallel to a longitudinal axis of a table supporting the material. The first and second carriage units have first and second arms, respectively. A cutting device coupled to the first arm forms a slit in the material, and a deburring device coupled to the second arm forcibly removes burrs from the slit. The deburring device is behind the cutting device relative to the travel direction and forcibly removes burrs in the travel direction toward a breakthrough point of the slit. The second carriage unit oscillates parallel to the travel direction so that the deburring device moves toward and away from the breakthrough point of the slit to remove burrs at the breakthrough point.

Provided are a robot system, a robot control device, a control method, and a program which make it possible to more simply teach a robot action. The robot system comprises: a feature point teaching unit which causes a storage unit to store the position of a feature point that has been taught using lead-through; an input accepting unit which accepts the input of an angle value of a tool with respect to a workpiece W; a posture determining unit which determines the posture of the tool on the basis of the angle value of the tool; and a program generating unit which generates a robot program for a robot on the basis of the position of the feature point and the posture.

A device for moving at least one cutting and welding arrangement able to cut, then weld a tail of a first metal strip to a head of a second metal strip, includes at least one first carriage holding at least one welding head. The first carriage is movable over a guide path following a first course across a transverse strip region. At least one second carriage is movable separately from the first carriage and holds a cutting head. The second carriage is movable on a guide path following a second course. The welding head is used exclusively for a welding mode, the second carriage is used exclusively for a cutting mode and the two carriages have parked positions on either side of the tail and head widths of the strips. A welding method which is associated with the device is also provided.

A robotic welding system comprises a supporting arm for attaching to a repositionable support structure, the supporting arm comprising a first mounting portion connectable to the repositionable support structure, and a second mounting portion rotatably coupled to the first mounting portion. A yaw rotary actuator rotates the second mounting portion about a yaw axis. A welding arm comprises a third mounting portion rotatably coupled to the second mounting portion of the supporting arm. A pitch rotary actuator rotates the third mounting portion about a pitch axis generally perpendicular to the yaw axis. A roll rotary actuator rotates a torch holder shaft about a roll axis generally perpendicular to the pitch axis. The shaft has a torch mounting portion for mounting a welding torch at an end thereof. A controller is operably coupled to the actuators to cause the welding torch to execute a welding pattern.

The present invention features a computer-implemented method of planning a processing path relative to a three-dimensional workpiece for a plasma arc cutting system coupled to a robotic arm. The method includes receiving input data from a user comprising (i) Computer-Aided Design (CAD) data for specifying a desired part to be processed from the three-dimensional workpiece, and (ii) one or more desired parameters for operating the plasma arc cutting system. A plurality of features of the desired part to be formed on the three-dimensional workpiece are identified based on the CAD data. The method also includes dynamically filtering a library of cut charts based on the plurality of features and the desired operating parameters to determine a recommended cut chart for processing the plurality of features. The method further includes generating the processing path based on the recommended cut chart and the plurality of features to be formed.

Cutting torch guide structures, systems, and kits include a base structure having a bottom surface and a channel formed in the base structure, a mechanically switched permanent magnet coupled to the base structure and configured to mechanically switch between two magnetic states, and a cutting torch guide structure configured to be releasably received in the channel and magnetically coupled to the base structure by magnetic attraction between a at least one permanent magnet fixed in at least one recess in the channel and a guide structure permanent magnet fixed to the cutting torch guide structure, where the cutting torch guide structure is configured with a first portion that is removable received in the channel of the base structure and a second portion that overhangs the base structure and includes an edge that defines a predefined shape and is configured to be in slidable contact with a cutting torch tip.

An interpolation parameter calculation unit calculates an interpolation parameter of a predetermined interpolation calculation formula based on a first plurality of coordinate values input by means of a coordinate input unit and constituting a coordinate pattern for determining a locus pattern of one cycle when a laser beam is vibrated. A locus pattern calculation unit calculates a second plurality of coordinate values constituting the locus pattern based on an interpolation parameter, respective amplitudes of the locus pattern in an x-axis direction that is a moving direction of a processing head and a y-axis direction that is a direction orthogonal to the x-axis direction, a frequency of the locus pattern, and a control cycle of a beam vibration mechanism for vibrating the laser beam.

A laser engraver comprises a generally rectangular housing with an open bottom adapted to rest on supports provided at the top plane of an open carriage. Thumb wheel screws operating in fixed nuts on the left and right sides of the laser housing and resting on supports at the top plane of the carriage allow the laser housing can be raised, lower and tilted. A plate can be removably and adjustably mountable within the housing directly under the laser for carrying smaller objects. A cart capable of carrying objects to be engraved can be moved into the space between the carriage side panels and is provided with height and level adjustments to support an object to be engraved by the laser when the removable plate is taken out of the laser housing.
