The flash removal unit presented herein is suitable for a friction stir welding (FSW) head and includes a blade and an annular body. The blade removes flash created by a FSW tool during FSW operations. The an annular body defines a flash capture area around the blade and is configured to at least temporarily retain the flash removed by the blade within the flash capture area. The flash removal unit may also define a flow path along which the flash can be suctioned away from the flash removal unit.

Provided is a spatter scattering prevention apparatus that eliminates the necessity to, for example, remove scattered spatters and thus makes it possible to facilitate maintenance work, and also provided is a flash butt welder including the spatter scattering prevention apparatus.

The spatter scattering prevention apparatus 1 according to the present invention is characterized by being configured to form a water screen in midair in the vicinity of a welding spot, at which welding is performed, wherein the water screen is for preventing spatters, generated during the welding, from scattering.

The spatter scattering prevention apparatus is also characterized by being configured to form the water screen on one side in a lateral direction of the welding spot and form the water screen on the other side, laterally opposite to the one side, of the welding spot.

An airborne component extraction system includes a source of a positive pressure air stream and a source of a negative pressure air stream. The air streams are directed through conduits to a hood that distributes the positive pressure air stream into a work area, and that draws the negative pressure air stream from the work area to remove airborne components within the work area. Aspects of the hood offer greatly enhanced performance in creating a controlled region for component removal and for drawing and removing the components for the work area.

The present invention relates to a welding device which includes a welding power source provided with a power supply circuit; a wire feeder connected to the welding power supply to supply wire; a torch which pulls the wire supplied from the wire feeder and supplies the wire to a welding part; an IR thermal camera which captures the welding part; a vision module having built-in program which receives and processes a captured image of a IR thermal camera; and a slag removal device which removes slag detected in the welding part in real time in conjunction with the vision module. The welding device has an effect in which slag generated during welding can be removed before the slag is fixed on the molten pool.

To solve the problems of conventional wire billet butt-welding such as high labor intensity, potential safety hazards, and low production efficiency, the disclosure provides a wire billet butt-welding apparatus and a wire billet butt-welding method. The wire billet butt-welding method comprises: S1: preparing a stock, S2: rotating a butt-welding stock receiver to a stock receiving position, and feeding a first coil of wire billet to a stock receiving rod of the butt-welding stock receiver; S3: welding the first coil of wire billet and the second coil of wire billet on a rotary plate at the butt-welding position end-to-head; S4: rotating the butt-welding stock receiver and the second coil of wire billet to the stock receiving position; S5: rotating the stock receiving rod to rotate to tighten the wire billet between the first coil of wire billet and the second coil of wire billet; and S6: repeating steps S3 to S5 to complete butt-welding operations on the 3.sup.rd to n.sup.th coils of wire billet sequentially. The solution implements semi-automated butt-welding operation; with provision of the rotary plate and the butt-welding stock receiver, enables automatic loading, automatic flipping, and automatic discharging, which reduces the manual workload, lowers the safety hazards, and improves the production efficiency.
