An ignition device for welding equipment includes a capacitor, a transformer, a high voltage output circuit connected to a secondary winding of the transformer, a discharging switch enabling discharge of the capacitor to a primary winding of the transformer, a charger and an operation control circuit that controls the charger and the discharging switch.

A welding apparatus has a guide rail arrangement with at least one guide rail attachable to a welding target. A carriage has a carriage housing and a rail follower assembly that is movably mountable to the guide rail arrangement for relative movement along the at least one guide rail. A feedstock source is disposed within the carriage housing and configured to deposit a feedstock material on a target surface of the welding target. An ultrasonic weld head is partially disposed within the carriage housing and has a sonotrode that extends toward the target surface so as to engage the deposited feedstock material and apply a normal welding force to the deposited feedstock material and the target surface. The sonotrode is operable to conduct ultrasonic vibrations into the deposited feedstock material and the target surface to weld the feedstock material to the target surface.

A method for processing a mortise of a small-size superalloy turbine disk using laser shock peening A laser shock peening (LSP) parameter of a laser shock peening (LSP) robot is designed. A spatial data of a motion trajectory of the LSP robot for a laser shock peening area of mortise teeth of the first mortise is found and recorded using a robot simulation system software to generate a trajectory program of the robot for the first mortise. Then a rotation program of an end of an arm of the LSP robot is written according to an included angle between two adjacent mortises to generate a trajectory program of the robot for all mortises of the turbine disk. Finally, the turbine disk is processed by laser shock peening.

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.

A plasma-torch cutting machine gantry moves in a first axis and the torch mounted through a pantograph to a drive box moves along the gantry in a second axis. The drive box rotates the torch about a third axis, and tilts the torch about a fourth axis. The drive box moves vertically in a fifth axis. The torch is mountable with tip at pantograph focal point or in an extended position. A controller firmware computes and apply offsets in the first, second and fifth axis to maintain the plasma torch tip in desired position despite the torch being mounted in extended position, rotation and tilt of the torch. In embodiments the torch is rotatable −/+90 degrees from vertical; and a laser scanner maps surfaces and edges of beams to determine movements and rotations for cutting beams.

An electrical connector can be provided for connecting a power source to an insertable conductor, including an igniter for exothermic weld material. One or more conductors can be disposed within a housing that is configured to receive the insertable conductor. An actuator can be engaged from outside the housing to move at least one of the conductors within the housing between resting and actuated orientations.

Soldering system includes a 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.

An automatic and manual welding apparatus includes an operation changeover switch which is provided to be capable of switching a manual input mode for switching off power supplied to an infeed motor to and from an automatic input mode for applying power supplied to the infeed motor, so as to switch the rotation of the infeed motor automatically and manually. A control unit controls the infeed motor such that the power supplied to the forward and backward transfer motor is switched off when the input of the operation changeover switch is in a manual input mode and the power to the infeed motor is applied when the input of the operation changeover switch is in an automatic input mode.

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.
