Control method of a welding device having an upper tool, lower tool, control unit and welding device positioning arrangement for a drive system having no or little mechanical losses. In the method, the lower and upper tools are moved relative to each other, the drive system of the positioning arrangement presses first and second components against each other and, during the actuating of the drive system, a force is measured at a static first section (and/or a position of a movable second section of the positioning arrangement relative to the static first section). The measured force and/or position is compared with a predetermined force and/or position, and actuating is stopped after the predetermined force and/or position has been reached. Subsequently, the first and second components are welded to each other, the drive system is actuated, and the lower and upper tools are moved relative to each other.

A system for welding together tips of different wires arranged about a motor stator. A scanner control module is configured to operate a three-dimensional scanner to scan the tips of the different wires and measure alignment of the tips in X, Y, and Z directions of a coordinate plane. A system control module is configured to compare the measured alignment of the tips to a predetermined alignment range, and configured to identify a weld schedule for each of the tips that fall within the predetermined alignment range. A laser welder control module is configured to operate a laser welder to weld together only the tips aligned within the predetermined alignment range in accordance with the weld schedule identified by the system control module.

An apparatus (10) for joining a predetermined geometrical profile shape from a sheet material (SM) includes a positioning assembly (12) including a base member (14) and a frame (16) that is operable to receive the sheet material (SM), to configure the sheet material in a predetermined orientation and to linearly translate the sheet material along a process direction (20). A Z-bar (22) is configured to guide a first longitudinal edge (FE) and second longitudinal edge (SE) of the sheet material (SM) into adjacent alignment along the process direction (20). A welding and forging assembly (60) welds and then forges a seam between the first longitudinal edge (FE) and the second longitudinal edge (SE) of the associated sheet material (SM).

Soldering system includesa first soldering device having a control apparatus that has a central microcontroller and/or microprocessor and is designed for controlling at least one operating parameter of the soldering device, wherein a radio module is provided which includes a communication module designed for setting up a wireless data connection,and at least a second soldering device having a control apparatus that has a central microcontroller and/or microprocessor and is designed for controlling at least one operating parameter of the soldering device, wherein a radio module is provided which comprises a communication module designed for setting up a wireless data connection.

The present disclosure teaches systems and methods for robotic welding of studs onto the surface of I-beams. These systems and methods will find industrial applicability in, for example, the steel erection industry.

Systems and methods are provided for engine idling without battery in welding-type setups. An engine-driven welding-type power supply system may comprise an engine; a generator configured to convert mechanical power from the engine to electric power; a power conditioning circuit for converting output power from the generator to welding-type output power for use in welding-type operations; a controller configured to control operations of the engine; and a power supply component configured to provide power to the controller. Controlling operations of the engine may comprise automatically transitioning the engine to and/or from an idle mode (in which the engine idles); and the power supply component may be configured to provide power to the controller during at least the idle mode, and without use of a starting battery. The transitioning to and/or from idle mode may be done automatically.

Provided is a welding robot mechanism that has: a welding robot having a touch sensing function; a welding power source for supplying welding power to the welding robot; and a control unit for controlling the welding robot, wherein the welding power source has a welding power source communication unit that receives detection signals with regard to control of the welding robot and the touch sensing, and transmits the detection signals outward. The control unit is linked to the welding power source communication unit via a serial bus communication wire. The detection signals comprise a mass of data including a detection data group designated as a first group and a detection data group designated as a second group, and is configured to read the detection data group designated as the first group in a shorter cycle than that for the detection data group designated as the second group. The detection data group designated as the first group includes a detection signal obtained by the touch sensing.

A system and method for cutting a workpiece utilizing a plasma cutting tool of fixed cut width into at least two parts having prescribed shapes from a metal plate comprising the steps of: identifying each of the parts by one or more contour lines; cutting a workpiece along one of the identifying contour lines into one of the parts using a tool of fixed cutting width; utilizing this cut contour of fixed width as part of the contour on an adjacent part fully overlapping the cut width. The process is repeated until all the required parts are cut.

A support ring supports a welding ring to guide welding bugs around a coated pipe section. The support ring has a tubular body to support the welding ring, the body having substantially circular curvature around a longitudinal axis. At least one grounding extension connected to the body is offset longitudinally and radially outwardly with respect to the body and the longitudinal axis. This allows the grounding extension to lie radially outboard of a parent coating of the pipe section while the body encircles a cut-back end zone where the parent coating has been cut back. Pipe sections abutting end-to-end for welding can each be fitted with these support rings. This enables welding rings to encircle both of the cut-back end zones and allows effective grounding connections to be made without enlarging the cut-back end zones.

In some examples, an autonomous robotic welding system comprises a workspace including a part having a seam, a sensor configured to capture multiple images within the workspace, a robot configured to lay weld along the seam, and a controller. The controller is configured to identify the seam on the part in the workspace based on the multiple images, plan a path for the robot to follow when welding the seam, the path including multiple different configurations of the robot, and instruct the robot to weld the seam according to the planned path.
