Influence Of Non-Conventional Beam Profile On Edge Effects In Laser Forming Of AISI 304 Stainless Steel Plate

Laser forming is an innovative technique that uses a defocused laser beam to form sheet metal by thermal stresses rather than external forces. This offers excellent and promising potential applications in rapid prototyping, straightening, aligning, and adjusting of macro/micrometallic components. Ho...
