    • Abstract
  • The cable-type welding wire (CWW) was used as filler for submerged arc welding (SAW)process, which is comprised of seven wires with a diameter of 2.4 mm. One wire is in the center, while others uniformly distribute around it. The finite element numerical analysis model was established for the residual stress of CWW-SAW joint, based on thermal elastoplastic theory. The residual stress was simulated through ANSYS software. The experimental results obtained by the hole drilling method agreed well with the simulated results on the top surface, verifying the exactness of the model. The results show that the stress distribution and amplitude of the CWW-SAW joint are basically corresponding with that of the single-wire SAW joint. The longitudinal stress presented tensile effect in the weld seam and at the region near fusion line, while the peak stress was 363 MPa. The transverse stress was a bit small, presenting tensile effect on upper and the lower parts while compressed effect appeared in middle part.
