IPG’s In-line weld monitoring system uses In-line Coherent Imaging (ICI) to confirm the quality of welded parts with real-time measurements. An IR laser beam fired through the same optics as the welding laser records the welding parameters during the process. Paired with IPG’s OmniWELD Scanning software, the LDD-700 offers five monitoring modes: keyhole depth, seam profile, workpiece height, finished weld surface height and bead profile—all from a single instrument. Active steering of the ICI beam allows OmniWELD to seek out defects immediately before, during and after the welding process. These capabilities are available in a single presentation of the part with little to no additional cycle time or fixturing required. The optimal combination of measurement types, locations, and PASS/FAIL criteria for each weld process can be configured in software, simplifying replication on multiple systems. The LDD-700 is compatible with IPG’s fixed welding heads and 2-D high power scanner.
