摘要： A clad welding method, which can prevent the occurrence of incomplete fusion, and can cover the surface of a base material over a wide range with a weld metal, while suppressing the dilution of the weld metal, by use of a relatively simple technique, is provided. For this purpose, a welding heat input is increased at a location where one end (10a) of a preceding weld bead (10) and the other end (20b) of a succeeding weld bead (20) overlap, as compared with a welding heat input at a location where the preceding weld bead (10) and the succeeding weld bead (20) do not overlap, to produce a deep penetration portion (12a) involving locally deep penetration (12).

摘要： An object is to provide a method and a system for improving a residual stress in a tube body, with which the residual stress can reliably be improved without heating excessively. From an irradiation start angle θs to a first predetermined angle θ1 on the tube body, an intensity of a laser beam is gradually increased from 0.5 to the steady output of 1.0 output ratio; from the first predetermined angle θ1 to a second predetermined angle θ2, the intensity of the laser beam is set at 1.0 output ratio; from the second predetermined angle θ2 to an irradiation end angle θe, the intensity of the laser beam is gradually decreased from the 1.0 output ratio to 0.5; and at the irradiation end angle θe, the intensity of the laser beam is set to 0. All these steps are performed at one turn of rotation in the method and the system for improving residual stress in the tube body.
