영문 초록

The purpose of this thesis was to investigate the welding characteristics and the residual stress behavior of SS41, commonly using power station, aircraft and ship. The experimented material was GMA welded in order to look over the residual stress distribution was measured under perfect restraint and nonrestraint welding conditions. From these test, we reached conclusion as followings ; The welding residual stress welded specimens was much higher in restraint condition than in nonrestraint. In case of restraint welding, the σx direction residual stress was measured the tensile residual stress. In case of nonrestraint welding, it was rapidly changed to compressive residual stress at about 15mm from welding bead center. In case of nonrestraint welding, the σy direction residual stress was measured the tensile residual stress. In case of restraint welding, it was changed to compressive residual stress at 40～45mm from welding bead center.
