Shops can easily weld metal tubes to solids, sheetmetal, and other tubes thanks to a new resistance-welding method developed at Delphi Corp., Troy, Mich. Annular-deformation-resistance welding (ADRW) ...

DRW also allows the use of dissimilar materials to optimise cost and performance. It can create leak-tight joints with uniform circumferential weld strength and can be applied to tubular structures ...

Furthermore, advanced finite element simulations have been applied to investigate the fracture response of 1422‑mm diameter pipelines featuring double‑V groove weld joints and circumferential ...

This then maintains the required pressure until the weld joint has solidified. ... Soniqtwist® however, produces small amplitudes of typically 30μm pp in a circumferential manner at the perimeter of ...
