The invention relates to the technical field of welding equipment, and discloses a pipe welding machine convenient to move. The pipe welding machine convenient to move comprises a base, fixing columnsare fixedly connected to the two sides of the base, a fixing plate is fixedly connected to the top of each fixing column, and a hydraulic telescopic rod is fixedly connected to the side, far away from the corresponding fixing column, of the bottom of each fixing plate; a circular-ring-shaped column is fixedly connected to an inner cavity of each fixing plate, and a movable column is movably sleeved with each circular-ring-shaped column; and a fixing block is fixedly connected to the top of each fixing plate, a limiting groove is formed in the side, close to the corresponding movable column, of each fixing block, a clamping block is movably sleeved with each limiting groove, and a clamping groove is formed in the side, close to the corresponding fixing block, of each movable column. According to the pipe welding machine convenient to move, through cooperation of the hydraulic telescopic rods, the movable columns, the fixing blocks, the limiting grooves, the clamping blocks and the clamping grooves, each pipe welding machine can be moved only through one person, manpower and time which are consumed when the pipe welding machine is moved are reduced, and the pipe welding machine moving efficiency of workers is improved.
