The utility model discloses an overhead transmission line precast concrete tubular pile anticorrosion welded joint device, including the upper and lower tubular pile that is equipped with welded jointrespectively, its characterized in that welded joint's end plate is cyclic annular toper so that the outer fringe of two adapter plates that are connected forms the triangle -shaped mouth, performs full weld surface coating resistance to corrosion material in the triangle -shaped mouth. The utility model discloses a to connect the end plate makes the toper to the outer fringe of two adapter plates that the messenger is connected forms the triangle -shaped mouth and performs the full weld, when making the tubular pile pile sinking welding seam and domatic not with the soil friction, and at welding seam surface coating resistance to corrosion material, thereby has completely cut off naked adapter plate and corrosive medium's contact, thereby has reached the anti -corrosion purpose.
