Laser welding of additively manufactured AlSi10Mg and conventionally manufactured Al6061 alloy
In the present study, laser welding of additively manufactured AlSi10Mg was undertaken with AlSi10Mg (similar) and Al6061 (dissimilar) alloy. The aim was to understand the laser weldability of selective laser melting (SLM)-printed AlSi10Mg alloy without filler material. The similar and dissimilar type of butt joints were prepared, and it is found that dissimilar weldments had better mechanical properties than similar weldments. The heat treatment on these welded plates also improved their mechanical properties. The precipitation of Mg2Si particles was evident from the XRD and TEM analysis. The as-built cellular structure was broken due to heat treatment and also near the weld zone in the as-welded plate. It was observed that microhardness increased with increase in Mg2Si content after the heat treatment process. The strength of welded samples was less than that of the base metals. The heat treatment results in ~ 20% increase in the tensile strength of the welded samples with significant increase in elongation.
