Abstract
In comparison with other additive methods, the wire additive manufacturing has some advantages, chief among: high deposition rate and low price for consumables. Otherwise there are some disadvantages such as a high level of internal defects (hot, cold cracks, pores). Adding laser radiation to a WAAM process can significantly reduce data flaws. In this paper outlined research results on the effect of laser radiation (pulsed and permanent) on structure and internal defects of deposit layers to create three-component structures from AlMg6 alloy. Reported samples was made by using hybrid laser-arc method and by applying a single laser. Presented photos of macrosections of obtained samples. Spectral analysis was performed to identify the nature of changes of grains in different processes. Were made the measurements of internal defects and chemical analysis of the obtained walls.
