PURPOSE: An automatic pipe welding device is provided to control the speed of the rotation of a welding machine, since the welding machine is rotated by gear engagement. CONSTITUTION: An automatic pipe welding device comprises a clamping member(10), a rotary shaft member(20), a rotation guide member(30), and a carriage(40). The clamping member is formed on the peripheral surface of the pipe member. The rotary shaft member is circumscribed to the outer surface of the clamping member and is rotated by external force. The rotation guide member guides the rotation of the rotary shaft member along the circumferential trajectory of the clamping member. The carriage moves with the rotary shaft member along the circumferential trajectory of the pipe member. A welding rod of the carriage is welded along the junction between the pipe member and an object.
