IPG Photonics launched LightWeld XR, the third product offering within its handheld laser welding product line. This model addresses more materials and thicknesses by producing a smaller spot size delivering more than six times the energy density. This increase in focused energy makes weld penetration of thicker materials easier, faster and deeper while minimizing the heat-affected zone and reducing distortion of the surrounding surface area. It extends the welding range of material thicknesses on steel and aluminum up to 0.250 in., titanium and nickel alloys up to 0.200 in., and copper up to 0.080 in.
