Abstract
A welding method of welding a cylindrical stiffening member to an outer circumference of a superconducting accelerator tube body uses 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 5.8×10W/cmor more.
