Systems and methods are disclosed relating to welding-type power supplies. In some examples, the power supplies may have no vents, which may help prevent environmental contaminants from entering the power supplies. Instead, the power supplies include one or more thermal interfaces configured to conduct heat generated by internal circuitry of the power supply from the interior of the power supply to an exterior of the power supply. Additionally, the thermal interface(s) may be configured for attachment to one or more exterior heat dissipating devices.

A irradiation welding apparatus including an irradiation welding generator having at least one irradiation welding head configured to apply an irradiation treatment to end contact surfaces of a first profile and a second profile to join the first profile and the second profile, where the at least one irradiation welding head forms a planar cross-sectional shape in an x-y directional plane relative to the irradiation welding generator.

A screw conveyor comprises a shaft, a screw flight arranged to extend helically around, and connected to the shaft at the outer circumference of the shaft, and extending in axial direction along at least a portion of the shaft, wherein the screw flight has an outer edge at the outer circumference of the screw flight, and at least one recess for receiving fibrous material is arranged in the outer edge of the screw flight. The screw flight has a cross-sectional profile with a width in the region of the outer circumference of the screw flight greater than the width in the region of the inner circumference of the screw flight. Furthermore, the invention relates to a separator device for dewatering moist masses, including liquid manure residues and/or digestates, as well as a method for additively manufacturing a screw conveyor and a use of a screw conveyor.

A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.

A lap fillet weld joint and a lap fillet weld joint manufacturing method are provided. On a side of a first edge, a first metal plate is provided with a bulging portion that has an internal space of a prescribed size, and a second metal plate has a protruding portion that faces to the bulging portion and can be inserted into the bulging portion. In a state in which the protruding portion has been inserted into the bulging portion, the first metal plate and a second edge of the second metal plate are welded, and a first weld bead is formed.

A method for using a plasma torch includes delivering a plasma gas through a plasma gas flow channel of a plasma torch while ionizing the plasma gas to produce a plasma arc that extends between the electrode and the workpiece. Additionally, shield fluid is delivered through a shield flow channel at a first pressure. A piercing operation to produce a pierce hole in the workpiece using the plasma arc is initiated while the shield fluid is delivered through the shield flow channel at the first pressure. After conducting the piercing operation for an amount of time, the shield fluid is delivered to the shield flow channel at a second pressure that is higher than the first pressure. Subsequent to the piercing operation, performing a cutting operation that forms a cut in the workpiece that originates at and extends away from a boundary of the pierce hole.
