Abstract: An apparatus for multi-bead welding of two rotating workpieces with a welding seam, which is deep relative to the maximum radius of the workpieces, includes a flat filler wire holder which can be inserted into the gap between the workpieces and which is periodically pivoted forth and back about an axis which at the beginning of the welding operation is located within the gap. The holder may be angled and comprise a first limb extending generally perpendicular to the axis of rotation of the workpieces and which holds the filler wire, and a second limb extending out of the gap in the direction of the pivot axis. A pipe for supplying welding powder or protective gas may be mounted on the holder parallel to the second limb thereof. At its inner end the pipe may carry a sensor which controls the outward movement of the holder during the welding operation.

Abstract: There is disclosed a machine for successively applying weld metal to the journals and crankpins of an automotive crankshaft, by rotating the crankshaft on its axis, and employing a means for causing a weld metal feeding torch to follow the crankpin around its circular or planetary path travel, depositing a bead of weld metal on the crankpin. The torch is also translated along the crankpin, and a bead or beads of molten metal is or are then wrapped around the crankpin, preferably in a succession of adjacent circles, and welds thereto. The layer of weld metal thus added is subsequently machined to its proper dimensions.

Abstract: An apparatus and method capable of applying weld material to metal parts on a generally automatic basis. The apparatus and method are uniquely adapted to apply weld material to the journals and crankpins and crank arms of an automotive type crankshaft on a generally automatic basis. The apparatus comprises a frame and a head stock and tail stock for rotatably supporting a crankshaft relative to the frame. A carriage is shiftable relative to the crankshaft and in a direction generally parallel to the central axis of the crankshaft. A welding torch is carried by the carriage and shiftable longitudinally and generally parallel to the central axis of said crankshaft. A torch positioning mechanism in said carriage includes a member simultaneously moveable in two mutually perpendicular directions by a drive mechanism which also causes rotation of the crankshaft. The movement of the member causes the welding torch to move in a generally true circular path so that the tip of the torch will closely follow to orbiting movement of the crank pins and the journals of the crankshaft.

Abstract: A crankshaft is formed with stub web portions for attachment of balance weights. The crankshaft bearing surfaces are ground and then the weights are electron beam welded to the web portions, which have a stepped configuration to enable indexing for sequential weight welding. After hardening trimmer plates are fastened to the weights axially of the crankshaft to complete the balancing. This provides an inexpensive, easily machined, accurately balanced crankshaft.

Abstract: L'installation d'usinage laser (2) pour graver des rainures (8, 9) dans une paroi d'une pièce mécanique (4), en particulier d'une bielle pour moteur à explosion, est équipée d'un dispositif laser à fibre optique (12) et agencée pour fournir des impulsions laser. Le dispositif laser à fibre optique est commandé de manière que les impulsions laser présentent une puissance de crête supérieure à 400 W et au moins deux fois supérieure à la puissance moyenne maximal du dispositif laser et de manière que la durée des impulsions laser est dans le domaine des nanosecondes (1 ns à 1000 ns) ou inférieure. Selon un premier mode de réalisation, le dispositif laser a fibre optique est commandé dans un mode « qcw » (quasi continuous wave). Selon un deuxième mode de réalisation préféré, le dispositif laser à fibre optique est commandé dans un mode déclenché (Q-Switch). Les modes de fonctionnement sélectionnés permettent d'augmenter l'efficacité d'usinage et d'obtenir une rainure avec un profil transversal optimal, notamment un faible rayon de courbure moyen au fond de la rainure permettant ensuite un fractionnement précis de la pièce mécanique avec une moindre force.

Abstract: A procedure is described for the repair of gas turbine engine turbine components which involves the repair of cracks and other defects and the replacement of worn or eroded material followed by the laser melting of a thin layer of metal on the surface of the component in those areas requiring reconfiguration to return to the original dimensions. The reconfiguration by laser melting is also useful for new articles which are out of tolerance, and generally for shaping objects from metal sheet or plate.

Abstract: Herein disclosed is a process for forming a dispersion alloy layer on a metallic base. The powder of an alloy system, which will separate into two or more multi-liquid phases at a temperature equal to or higher than its melting point and will solidify, when quenched, with its individual liquid phases being separate and in which the ratio of the minimum to the maximum specific weight its individual liquid phases is 0.3 or higher, such as the powder of any alloy system of Cu-Ni(15%)-Fe(8%)-Si(3%)-B(1.5%) is applied to a metallic base. The powder thus applied is then melting and agitated while being irradiated with a laser beam oscillated. The agitated melt of the powder is then quenched to solidify with the movement of the laser beam thereby to form on the metallic base the dispersion alloy layer in which the solid particles of at least one of those phase such as silicide particles are dispersed in the matrix of the remaining one of the phases.
