Coherent | Body-in-White: Crack Free Laser Welding of High-Strength Steel (Automotive Industry)

High strength steel (HSS) has increasingly been used in the automotive industry for structural component production. However, one challenge of welding HSS is its tendency to cold crack. This translates into costly reworking of parts. HighLight FL-ARM technology helps address this problem because: • Our Adjustable Ring Mode (ARM) fiber laser delivers crack-free welds at higher feed rates than standard solutions. • ARM technology permits the use of specialized laser power recipes at weld termination points, allowing you to control the dynamics of end crater formation, thus preventing cold cracks.
