The method for removing a weld bead includes (a) the steps of preparing a scraper having a higher melting point than the melting points of the base metal and the welding rod; (b) heating the base metal and the welding rod to a temperature lower than the melting points of the scrapers to form a molten pool in which the base metal and the welding rod are fused together; (d) moving the at least part along a second surface of the scraper opposite to the first surface facing the base material, thereby discharging the at least part backward, opposite to the forward movement direction of the scraper in step (c).

A wire billet butt-welding apparatus and a wire billet butt-welding method, the method including: 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.

Embodiments relate generally to systems and methods for preventing arcing within a snap action switch, particularly by removing a portion of a contact carrier attached to a stationary contact. A method of forming a contact for use in a snap action switch may comprise welding a contact onto a contact carrier; trimming at least one edge of the contact carrier proximate to the contact; and installing the contact carrier into a snap action switch housing. Trimming the at least one edge of the contact carrier may also comprise removing flash formed during the welding of the contact to the contact carrier.

Systems and methods suitable for cutting a material and deburring devices for performing a deburring operation on an edge of the material. Such a system includes a frame and table systems supported by the frame. Each table system includes a table for supporting the material and each table system is independently movable relative to the frame in lateral directions. A first carriage unit and second carriage units are supported by the frame and independently operable to travel in a travel direction transverse to the lateral directions. The first carriage unit includes multiple cutting devices, and the second carriage units includes multiple deburring devices. Each cutting device operates in conjunction with a corresponding one of the deburring devices, and the cutting and deburring devices are independently operable to cause the cutting devices and the deburring devices to simultaneously travel in the travel direction.

Disclosed herein is an electrolytic brush assembly comprising a handle assembly; a shroud extending from the handle assembly, the shroud having an aperture at a distal end thereof; a brush connecting assembly for releasably connecting a brush to the handle assembly whereby the brush extends through the aperture of the shroud and a fluid delivery assembly. The handle assembly comprises an adjustment sub-assembly for selectively moving the brush connecting assembly and a brush connected thereto relative to the handle assembly and the aperture of the shroud. The fluid delivery assembly delivers electrolytic fluid to the proximity of the brush, optionally under closed loop control.

A laser cutting assembly with a laser cutter, a worktable including a plurality of slats, and a slug removal assembly. The slug removal assembly includes a movable support, at least one scraper plate, and a resilience system linking the at least one scraper plate to the movable support. The at least one scraper plate is configured to contact a corresponding one of the plurality of slats. The movable support is configured to move across the worktable such that the at least one scraper plate contacts a corresponding one of the plurality of slats.

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.
