A Study on Bead on Plate Welding of AA7075 By Low Power Fiber Laser

AA7075 aluminium alloy has many advantages due to its light weight, low density, high corrosion resistance, and high strength metal. In order to have a strong weld joint, the weld penetration should be maximized, as well as the heat affected zone (HAZ) and weld width should be minimized. Laser weld...
