Abstract
In order to study the welding process of 5052 aluminum alloy,5052 aluminum alloy plates in 1.5mm thick were welded with pulsed and continuous laser respectively,then the process parameters were improved.After comparing their microstructures,tensile strength and micro hardness,it can be seen that pulsed laser welding is more ideal for control the porosity of welding joint,its welding quality is more excellent,and that the tensile strength of the welding joint is increased by 10%.The results show that both pulsed laser welding and continuous laser welding can make welded samples obtain ideal welds morphology and high tensile strength.
