In the case of strengthening of existing structures by welding under loading, compressive members may buckle during welding because welding heat input decreases Young's modulus and yield strength. Even though buckling does not occur during strengthening works, load carrying capacity of the members may decrease less than that of members welded without loading, as welding under compressive load causes larger deformation and introduces additional residual stress in the members. In this paper, pipes were welded under axial compressive loading to study the stability during welding. Next, load carrying capacity of those pipes which were stable during welding were examined.
