Laser Welded Corrugated Thin Metal Sheets

日益严重的环境问题正鼓励航空航天、船舶和汽车等行业通过使用轻质材料来改善其组装重量。在欧洲，到2025年，OEM销售的所有车辆的平均排放量需要从140克/公里降至75克/公里以下（麦肯锡公司）。波纹材料已被证明可以生产重量轻、强度高的结构。然而，适用于波纹的金属片很薄，远低于1毫米，因此在焊接到基板上时容易发生破坏性熔化和翘曲。ALT将利用薄箔焊接钢的原理，通过处理连续激光焊接来消除这些问题。这将导致激光焊接波纹薄金属板的生产，可以形成轻质、高强度的金属板来代替较重的板钢板

Rising environmental concerns are encouraging industries such as aerospace, marine andautomotive to improve their assembly weights by using lightweight materials. In Europe, theaverage emissions of all vehicles sold by an OEM in one year need to decrease from 140g/kmto less than 75g/km by 2025 (McKinsey & Co). Corrugation has proven to producelightweight, high strength structures. However metal sheets that are suitable for corrugationare thin, well below 1mm, and therefore vulnerable to destructive melting and warping whenwelded to a substrate. ALT will utilise the principles of thin foil welding of steel to eliminatethese problems by processing a continuous laser weld. This will lead to the production of laserwelded corrugated thin metal sheets that can form lightweight, high strength metal sheets toreplace, heavier, plate steel sheeting
