“…The main challenges of the oil and gas industry are related to the exploration of deep and ultra-deep wells, which present an aggressive environment with salt and gasses, like H 2 S and CO 2 . In this context, the usage of carbon steel pipes clad with a Corrosion Resistant Alloy (CRA) has proven to be a suitable option to meet design requirements at low manufacturing costs [1]- [3]. However, pipeline welding processes currently used by the oil and gas industry, such as fusion-based welding, often involve high temperatures and can cause metallurgical issues owing to dissimilar joints (e.g.…”

In this work, orbital friction stir welding (Orbital FSW) has been now developed in clad pipes, which is certainly of interest to the oil and gas industry. In this context, a system capable of performing sound joints in one pass with full tool penetration was developed. Therefore, orbital FSW was executed in clad pipes of 6 mm thick API X65 PSL2 steel and a 3 mm thick Inconel 625 with a polycrystalline cubic boron nitride (pcBN) tool. Furthermore, the metallurgical properties of the welded joints were investigated and discussed. Sound joints with axial forces of 45–50 kN, rotational speed of 400–500 rpm and welding speed of 2 mm/s were obtained, proving that the developed system can perform joints by orbital FSW without volumetric defects.
