The plurality of welding heads are each removably, mechanically coupleable to the support structure. The controller is configured to control welding operations of the automated welding system based on an identity of a particular welding head of the plurality of welding heads that is mechanically coupled to the support structure and operably coupled to the controller.

A laser processor includes a machining head and a cartridge configured to be inserted in the machining head. The machining head includes an optical path of a laser beam, a pressing member, and a stopper surface. The cartridge is configured to be pressed along the optical path toward the stopper surface by the pressing member when the cartridge is in the machining head. The cartridge includes an optical component configured to be positioned in the optical path when the cartridge is in the machining head. The optical component has a first surface and a second surface opposite to the first surface along the optical path, a first member configured to contact the first surface of the optical component and the pressing member, and a second member configured to contact the second surface of the optical component and the stopper surface.

A rotating are sensor is provided. The rotating arc sensor includes a motor, a connecting rod for driving a welding gun to perform an annular movement, a sliding assembly for supporting a weight of the connecting rod and supporting a free movement of a first end of the connecting rod, and an eccentric oscillating member for driving a second end of the connecting rod to perform the annular movement, wherein a center of a rotating shaft of the motor is provided with a hollow cavity capable of communicating with both ends of the motor, the sliding assembly is disposed at a top end of the motor, and the first end of the connecting rod protrudes out of the top end of the motor through the hollow cavity and is connected with the sliding assembly. The eccentric oscillating member includes a first flange and a second flange.

A fastener welding apparatus having a frame assembly, a welding assembly, a coupling assembly and a locating assembly. The welding assembly has a welder frame and a welding electrode assembly coupled thereto. The coupling assembly has a suspension frame, a frame axle and a welding axle. The frame axle is fixedly engaged to the frame assembly and the welding axle is fixedly engaged to the welding assembly. The suspension frame is pivotably coupled to each of the frame axle and the welding axle. The locating assembly is structurally configured to selectively allow the suspension frame to pivot relative to the frame axle and the welding axle.

A signal module and a signal relay device that can suppress the effect of noise are provided, and the signal module is a signal module of a tool changer including a first coupling member to be detachably attached to a body side of an industrial robot and a second coupling member to be detachably attached to a tool side, the signal module including a signal relay connector attached to the first coupling member or the second coupling member, and upon the first coupling member and the second coupling member being coupled, forming a signal path between the first coupling member side and the second coupling member side, wherein in the signal relay connector, a plurality of terminal pairs to be used for communication using differential signals are provided, and two terminals of each of the terminal pairs are arranged at mutually-adjacent positions.

This link actuation device includes: a proximal end side link hub; a distal end side link hub; and three or more link mechanisms which each couple the distal end side link hub to the proximal end side link hub. Each link mechanism includes: proximal side and distal side end link members, and an intermediate link member. The link mechanism is provided with an actuator which arbitrarily changes the posture of the distal end side link hub relative to the proximal end side link hub. A workpiece is disposed on the proximal end side link hub, and an end effector is disposed in the distal end side link hub so as to face inside of arrangement of the link hubs and perform work onto the workpiece.

A rotatable plasma torch is provided which can easily rotate when used in robotic or automatic cutting system while minimizing damage to internal connections of the torch. The torch is provided with a sleeve structure on the torch handle where there is no structure or component positioned between the sleeve and the exterior of the torch handle.

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.

Provided is an apparatus for coating a girth weld and a cutback region surrounding said girth weld, said apparatus having lateral travel at least equal to the length of the cutback region and circumferential rotational travel around the pipe. The apparatus can provide a multiple component coating accurately and safely, without the need for solvent flushing of the apparatus.
