The drill pipe has 5 inch (12.5 cm) outside diameter and riser has an outside diameter of 13 (33 cm). A submerged buoy supports riser weight. Riser tension is set to about...

... ABSTRACT Two configurations of welded joints of low carbon steel to Ni-based alloy 625 were studied: Lap joints with the processing performed through the low carbon steel plate. In the case, the welds were performed using three different rotational speeds (300, 350 and 400 rpm) at a constant...
