Abstract: A filter element for the filtration of fluids can be manufactured from powdered metal using a laser manufacturing process. The powdered metal is deposited in a layer on fabrication platform and a laser beam is directed toward the layer of material so that the powdered metal granules fuse together to form a first component of the filter element. Successive layers of powdered metal can be deposited over the first component and also fused with the laser beam to form additional components. During the manufacturing process, the power or scan rate of the laser beam many be changed so that the formed layers of the filter element may have different porosity characteristics, for example, with certain portions being fluid permeable and other portions being fluid impermeable.

Abstract: A welding apparatus for applying consecutive welding beads during a welding operation includes a welding unit including a torch head and a power circuit. The welding apparatus further includes a first pyrometer and a second pyrometer positioned respectively at a first and second pre-determined distance from a tip portion of the torch head, the first and second pyrometers are configured to respectively generate a first temperature signal and a second temperature signal indicative of temperatures of a portion of successive welds. The welding apparatus further includes a controller configured to receive the first temperature signal and the second temperature signal, determine a difference between the first and second temperature signals, set a predetermined threshold based, at least in part, on the determined difference, and adjust a welding parameter of the power circuit, wherein the adjusted welding parameter is lesser than the predetermined threshold.
