Internal and external welding integrated equipment for metal pipeline of fitness equipment

The invention belongs to the technical field of fitness equipment welding, and particularly relates to fitness equipment metal pipeline inside and outside welding integrated equipment which comprises a to-be-machined pipeline and a bracket used for supporting the pipeline and further comprises a welding ring arranged outside the pipeline and a welding disc arranged inside the pipeline. Walking devices which are uniformly distributed in an annular array are arranged on the inner side surface of the welding ring and the outer surface of the welding disc. According to the internal and external welding integrated equipment for the metal pipeline of the fitness equipment, the welding device is arranged, circumferential welding is conducted on the pipeline through rotation of a welding ring and a welding disc, a transmission motor controls a rotating handle and a grinding roller to rotate through transmission between a driving belt wheel and a transmission belt wheel, and then the rotating handle is driven to rotat
