Application of Automatic Arc Welding Process with High Speed Rotating to the Welding at Overhead Position

説明

Non-scallop welding of beam-column connections is effective in improving plastic deformations performance in earthquakes. However, for site welding of a flange to the underside of a beam, weld quality of overhead position is an important issue. We conducted experiments to estabrish appropriate non-scallop methods for ovrehead welding. The arc welding with high speedrotating is already successful for flat narrow gap welding. We report here on its apprication to overhead welding of flanges to the underside of beams, obtaining stable weld penetration in the root section by dispersion of the arc force.
