摘要： A method of laser spot welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12, 14, 150) is disclosed. The method includes directing a plurality of laser beams (24, 24′, 24″) at the top surface (20) of the workpiece stack-up to create a molten steel weld pool (92) that penetrates into the stack-up. The molten steel weld pool is then grown to penetrate further into the stack-up by increasing an overall combined irradiance of the laser beams while reducing the total projected sectional area (88) of the laser beams at a plane of the top surface of the workpiece stack-up. Increasing the overall combined irradiance of the laser beams may be accomplished by moving the focal points (66, 66′, 66″) of the laser beams closer to the top surface or by reducing the mean angle of incidence (86) of the laser beams so as to reduce the eccentricity of the individual projected sectional areas of the laser beams.

摘要： A method for manufacturing parts and molds by: 1) slicing a three-dimensional CAD model of a part or mold; 2) planning a modeling path according to slicing data of the three-dimensional CAD model, whereby generating numerical control codes for modeling processing; and 3) performing fused deposition modeling of powders or wire material of metal, intermetallic compounds, ceramic and composite functional gradient materials by layer using a welding gun on a substrate layer via a numerical control gas shielded welding beam or laser beam according to a track specified by the numerical control code for each layer. A micro-roller or a micro-extrusion unit is installed at a contact area between melted and softened areas. The micro-roller or the micro-extrusion unit synchronously moves along with fused deposition area, which results in compressing and processing of the fused deposition area during the fused deposition modeling.
