IPG Photonics Corp. released its LightWeld handheld laser welding system. Compared with traditional MIG and TIG welders, LightWeld enables faster welding, is easier to learn and operate, and provides consistent, high-quality results across a range of materials and thicknesses with low heat input and aesthetic finishes with minimal or no filler wire.  Simple controls, including 74 stored preset and user-defined process parameters, allow novice welders to be trained in hours. Experienced welders benefit from the rapid and flexible processing capabilities, which weld thick, thin and reflective metals with minimal distortion, deformation, undercut or burnthrough.
