Method of providing consistent quality of target material removal by lasers having different output performance characteristics

Laser pulse energy adjustments are motivated by an understanding of the effect of laser pulse width variations among different lasers on satisfying a quality metric associated with a laser-processed target. In a preferred embodiment, the adjustments normalize this effect among different lasers drilling vias in a target specimen. The number of pulses delivered to the target specimen to form each via can be modified, based on the pulse energy applied to the via location, to control different via quality metrics.

A method and system to weld or join workpieces employing a high intensity energy source to create a weld puddle and at least one resistive filler wire which is heated to at or near its melting temperature and deposited into the weld puddle.

System and method for plasma cutting sheet metal in an automated coil-line machine

A fully automated plasma sheet metal cutter that can be integrated into a HVAC coil-line and which increases the precision of cutting, decreases the time it takes to cut a particular component sheet metal part, and offers flexibility in cutting different sized and shaped holes or openings. Further, since the system is fully automated, it eliminates the error or cost attributed to a portion of the cutting process that heretofore has been associated with a manual laborer.

Protection cover for a spray nozzle during a hardfacing process

A protection cover suitable for being placed between a spray nozzle and a metal part during a process of resurfacing the metal part, the protection cover including a side wall extending along a reference axis, the side wall including an inner surface and an outer surface, the side wall having a lower end and an upper end, the side wall being perforated by at least one lateral gas inlet port, the lower end of the side wall being perforated by a notch into which a portion of the metal part can be inserted, the upper end of the side wall being provided with an opening into which a portion of the spray nozzle can be inserted. The inner surface of the side wall includes at least one frustoconical portion.

Wear-resistant roller

The invention relates to a wear-resistant roller for crushing of particulate material, such as crude ore for use in the cement or minerals industry comprising a roller body, a wear surface on the roller body. The wear surface comprises welding beads comprising a primary fraction of carbide material and a secondary fraction of material selected from the group consisting of Nickel, Nickel alloys, mixtures of Nickel and Nickel alloys and mixtures of Nickel containing refractory hard materials, Cobalt, Cobalt alloys, mixtures of Cobalt and Cobalt alloys and mixtures of Cobalt containing refractory hard materials. Furthermore, the welding beads are welded to the roller body in an overlapping manner such that two neighbouring welding beads comprise an overlapping volume and a non-overlapping volume, the overlapping volume being an intersection volume between the two neighbouring overlapping welding beads, and the fraction of carbide material being higher in the overlapping volume than in the non-overlapping volume such that the overlapping volume has a higher wear resistance compared to the non-overlapping volume having a lower wear-resistance. Also the invention relates to a method of forming such a wear surface on a roller body.

Apparatus and method for laser cleaning of coated materials prior to welding

A system and method is provided where a coated work piece is welded at high speeds with minimal porosity and spatter. The coating on the work piece is removed or ablated by a high energy heat source prior to being welded in a welding operation, such that high welding speeds are attained. The high energy heat source is positioned upstream of the welding operation to vaporize any surface coatings on a work piece.
