A method of forming a unitary metal piece includes providing first and second generally planar metallic portions. Each portion has generally parallel first and second sides opposite each other. Each portion has an end edge extending between the first and second sides. The first and second ends are proximate one another. The end edges are resistance welded together to form a weld joint and produce weld flash on at least one of the first and second sides of the portions. The weld flash on at least one of the first and second sides is ground, and a fluid is applied to the weld joint during the grinding of the weld flash.

Some examples include welding a first workpiece to a second workpiece. For instance, the first workpiece may be secured adjacent to the second workpiece. At least one of the first workpiece or the second workpiece includes a channel or a portion of a channel in a respective surface such that a complete channel is presented when the first workpiece and the second workpiece are secured adjacent to each other. A rotating tip of a welding tool is inserted into the complete channel for welding the first workpiece to the second workpiece. A surface burr resulting from the welding is located within the complete channel.

A processing device is configured for use within a storage container with an interior surface. The processing device can include a chassis with one or more support assemblies. The chassis can support one or more motive assemblies, which can be configured to engage the interior surface for movement of the chassis relative to the interior surface. The one or more support assemblies can be configured to support one or more tools, with the one or more tools being configured to execute one or more processes on the interior surface when the processing device is within the storage container.

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.

Shaping systems and methods suitable for cutting a material, and deburring devices for performing a deburring operation on an edge of the material. Such deburring devices include a manifold having at least first, second, and third nozzles having first, second, and third axes on different first, second, and third planes, respectively. The first, second, and third nozzles are adapted to project first, second, and third gas streams therefrom in the first, second, and third planes axes. A mechanism is provided for orienting the manifold to project the first, second, and third gas streams at the edge of the material.

A welding tool has a handle with a base end and an exit end. A bottom plate is affixed to the base end and preferably encloses the base end of the handle. A washer is affixed to the exit end of the handle. The washer defines an orifice and provides a surface for preventing a user's hand from slipping during use of the welding tool. A plurality of rods extends outwardly from the handle through the orifice. The rods are preferably affixed to the bottom plate at a base end and have a surface contacting end. The rods are sized to permit limited flexure, but to still be substantially rigid to effectively remove slag from a weld.

A flexible screen frame processor including a loading position that presents loading screen frame supports at which a partially formed flexible screen frame is supportable by an upper perimeter of the partially formed flexible screen frame and an end stripping position including at least one polymer coating stripper. A following welding position includes a welder and screen frame supports that support ends of the screen frame coaxially aligned. A post welding cleaning position includes weld spatter and flash cleaners. An unloading position includes unloading screen frame supports at which a welded and post-weld cleaned flexible screen frame is supportable by an upper perimeter of the welded flexible screen frame.
