A study on bead-on-plate welding of AA7075 using low power fiber laser
Journal of Mechanical Engineering and Sciences, 2016 Laser welding promises the best method to produce higher strength of aluminium joints compared to conventional arc welding process. Arc welding usually produces a large heat affected zone (HAZ), which leads to lower joint strength on aluminium alloys ...
