WebElectron beam welding (EBW) is a metal welding technique which takes place in a vacuum chamber using a beam of high energy electrons to heat the metal. This melts the material, creating a ‘keyhole’ which then solidifies as it fuses with another component. EBW is known for its precision, making it a popular choice for the Aerospace, Defence, Medical … WebKeyhole laser welding is capable of producing high aspect ratio welds (narrow weld width: large weld depth), resulting in narrow heat-affected zones. Laser beam welding can be used with crack sensitive materials, such as the 6000 series of aluminum alloys when combined with an appropriate filler material such as 4032 or 4047 aluminum alloys.
