A portable device for precision plasma and oxy-fuel torch cutting is provided. Versions of an example portable cutting torch tool guide the gun of a cutting torch to make precision linear cuts or curved cuts in a metal workpiece. In an implementation, the device is a gun for a cutting torch, with an integrated rail follower and adjustable vertical and horizontal offsets from a workpiece. The cutting torch tool may use various kinds of rails for stable cuts, with optional movement damping, motorized drive, servos for vertical and horizontal offset, and remote control with user interface.

A movement support includes a base. An air inlet is formed in the base. A drainage plate is installed on the base. A first heat dissipating flow channel communicated with the air inlet is formed in the base on one side of the drainage plate. A second heat dissipating flow channel communicated with the air inlet is formed in the base on the other side of the drainage plate. The first heat dissipating flow channel and the second heat dissipating flow channel between the drainage plate and the air inlet are communicated with each other.

An ultrasonic welding apparatus joins metal pieces, such as wires, which are placed in a weldment zone where the metal pieces are subjected to pressure through a compressive height anvil and an adjustable width anvil, and intimate contact is made with a sonotrode of an ultrasonic stack. A first electric motor actuates movement of the height anvil to develop a compressive force for ultrasonic welding of the metal pieces. A second electric motor can position the width anvil before and during welding. A sensor, such as a load cell, measures the compressive force developed. The sensor directly can measure the load on the height anvil independent of the ultrasonic stack. A software algorithm can compensate for deflection of the load cell sensor and lost motion in the first electric motor actuating movement.

An example robotic welding system, includes: a robotic manipulator configured to manipulate a welding torch; and a robotic controller, comprising: a processor; and a machine readable storage medium comprising machine readable instructions which, when executed by the processor, cause the processor to, in response to initiation of a robotic welding procedure involving the robotic manipulator: prior to starting the robotic welding procedure, output at least one of a visual notification or an audible notification proximate to the robotic manipulator; and after satisfying at least one weld-ready condition, control the robotic manipulator to perform the robotic welding procedure using the welding torch.

In certain embodiments, a portable metal working robot system includes a metal working tool configured to perform a metal working process on one or more metal parts. In addition, the portable metal working robot system includes communication circuitry configured to receive control signals from a control system located remotely from the portable metal working robot system. The portable metal working robot system also includes control circuitry configured to control operational parameters of the portable metal working robot system in accordance with the received control signals.

Methods for forming pierce holes in a metal workpiece are disclosed. According to one implementation, upon a plasma torch be energized, the cutting axis of the torch is rotated repeatedly between first and second angular positions to produce successively deeper pierces in a workpiece until a pierce hole is produced through a thickness of the workpiece. According to other implementations pierce holes are produced by rotating the cutting axis of the plasma torch tip around a designated central axis of the pierce hole in a diametrically reducing manner so that the produced pierce hole has a tapered profile with a cross-sectional area of the pierce hole at a top surface of the workpiece being greater than a cross-sectional area of the pierced hole at a bottom surface of the workpiece.
