Welding robot

The utility model relates to the technical field of welding equipment, and particularly discloses a welding robot which comprises a moving trolley and a welding gun connected with the moving trolley through a rotation driving assembly. The moving trolley is driven to drive the rotation driving assembly and the welding gun to move, and the rotation driving assembly drives the welding gun to rotate relative to the moving trolley on the plane perpendicular to the moving direction of the moving trolley. The welding robot can enter a long and narrow pipeline to weld an annular connecting seam in the pipeline, and the connection strength of the welding seam can be enhanced. 本申请涉及焊接设备技术领域，具体公开了一种焊接机器人，包括移动小车以及通过转动驱动组件与所述移动小车连接的焊枪；所述移动小车受驱带动所述转动驱动组件和所述焊枪运动，所述转动驱动组件带动所述焊枪相对于所述移动小车在垂直于所述移动小车的运动方向的平面转动。本申请提供的焊接机器人，能够进入狭长管道内部，对管道内部的环状连接缝实施焊接，有利于增强焊缝的连接强度。
