Laser welding (LW) is a promising method for joining the additive manufactured (AM) laser powder bed fusion manufactured (LPBF) 316L parts and increases the use cases for the technique by overcoming some of its limitations. The fatigue properties of LW LPBF 316L parts have not been previously studied, but it is an important factor in wide range of products, where the weight and lifetime should be optimized. The LW joints are analyzed by optical microscopy, tensile testing and bending fatigue testing, and the results show that this type of joints can be successfully used to manufacture products from LPBF parts. The achieved strength (over 627 MPa) and fatigue limit of over 200 MPa with the welds were comparable to the base material.
