PIPE WELDING DEVICE HAVING OXIDATION PREVENT FUNCTION

摘要

PURPOSE: A pipe welding device having an oxidation prevent function is provided to prevent a welding section from being oxidized by shielding a rear surface of the welding section from an atmosphere. CONSTITUTION: A pipe welding device includes a base(1). A roller(39) for moving a pipe(61) is rotatably coupled to the base(1) by means of a bracket(37). A support block(2) is vertically installed adjacent to the base(1). The support block(2) is aligned lengthwise along the pipe(61) in such a manner that a main shaft(27) is rotated in vertical to the support block(2). A driven gear(30) is coupled to the other end of the main shaft(27). The driven gear(30) is engaged with a driving gear(29) driven by a driving motor(28) fixed to an upper surface of the support block(2). A shaft is inserted into the main shaft(27) by interposing a bearing.
