Mechanical properties and microstructure of additively manufactured stainless steel with laser welded joints

•Microstructural analysis reveals narrow weld regions and HAZ generated by employed laser welding.•Anisotropy of additively manufactured base material and effects of energy input of laser welding are examined.•Local and global stress-strain relationships are determined using non-contact digital image correlation method.•Results of tensile tests on additively manufactured stainless steel coupons with laser welded joints are presented.•Variations in the mechanical properties are correlated with differences in internal microstructure.
