Electron beams reshape metal surfaces to promote joining.(Welding/Joining)

A joining technology in which electron beams precisely reshape metal surfaces by growing protrusions that rise from the surface of the material has been developed by TWI, Cambridge, England. Called Surfi-Sculpt, the protrusions and intrusions can be created in controlled arrays and with physical parameters that can be modified with extreme precision. These are created by precise application of a high-intensity electron beam controlled by a programmable system. As the electron beam is moved across the surface of a material, usually metal, it creates a small pool of molten metal in a ...
