摘要： Provided is a welding method of welding a cylindrical stiffening member to an outer circumference of a superconducting accelerator tube body using a laser beam in a process of manufacturing a superconducting accelerator tube. The laser beam is configured such that a distribution profile of energy density on an irradiated face to which the laser beam is irradiated is a Gaussian distribution profile having a peak section, and the energy density of the peak section is 5.8×10 5 W/cm 2 or more.
