Welding equipment capable of rapidly making up defects

The invention relates to the field of welding equipment, in particular to welding equipment capable of rapidly making up defects. The welding equipment capable of rapidly compensating the defects comprises a driving motor, a high-speed rotating shaft and the like; the driving motor is connected with the high-speed rotating shaft. After the high-speed rotating shaft drives the stirring head to drill into and penetrate through a profile, the lower shaft shoulder is installed on the elastic connecting assembly between the high-speed rotating shaft and the upper shaft shoulder by moving the clamping assembly, and when the high-speed rotating shaft drives the stirring head to rotate at a high speed to melt the profile into a molten soft state, the upper shaft shoulder and the lower shaft shoulder jointly extrude a molten soft area of the profile; and under the condition that the upper shaft shoulder and the lower shaft shoulder jointly clamp and flatten the melting softening area of the profile, the welding defect
