Abstract: A portable angle impact tool includes a housing, a motor, and a transmission mechanism. The transmission mechanism includes a transmission rod extending along an axis X, a spindle extending along an axis Y perpendicular to the axis X, an impact assembly for driving an output shaft and connected with the spindle, a first transmission element positioned on the transmission rod and engaging with a second transmission element positioned on the spindle, and a pinion positioned on of the transmission rod engaging with a gear on a motor shaft of the motor. In a direction of the axis Y, the impact assembly and the spindle are located on one side of the second transmission element and the longitudinal axis X of the transmission rod is located on the other side of the second transmission element to provide the impact tool with a more compact arrangement and higher output power from the output shaft.

Abstract: The magnesium-contained high-silicon aluminum alloys for use as structural materials, including profiles, bars, sheets, and forgings, are manufactured by a process including the steps of: casting an alloy ingot by direct chill casting, preheating the ingot to disperse eutectic Si phase particles, and thermal-plastic processing and heat-treating to obtain the product with a final shape and a modified microstructure. The aluminum alloys contain 0.2˜2.0 wt % of Mg and 8˜18 wt % of Si, and have homogeneous and fine microstructure, wherein the aluminum matrix is equiaxed with an average grain size less than 6 μm, and the silicon and second phase particles are dispersed with an average size less than 5 μm. Without adding any modifiers, they are low-costly produced by incorporating the direct chill casting with thermal-plastic processing and heat treatment, which give rise to good plasticity and relatively high strength.

Abstract: A method for beam welding a multi-sheet work stack includes providing a reduced thickness feature in a first sheet, positioning the first sheet adjacent to a second sheet to define a first welding interface, and positioning a third sheet adjacent to the second sheet to define a second welding interface. A laser or electron beam is directed through the first sheet at the feature to form a fusion weld at one of the welding interfaces. A second beam may be directed onto the other interface to form a second fusion weld. Providing a reduced thickness feature in the first sheet may include forming the feature with the beam and mechanically pre-forming the feature. One of the interfaces may be pre-heated using the beam, and the beam may be split using a beam splitter to form multiple beams. A welded assembly formed via the method is also disclosed.
