A WELDING APPARATUS

摘要

The present invention relates to a welding apparatus comprising: a supporting part installed in a member to be welded; a drive part combined to the upper part of the supporting part, and which is rotated or moved along a welded part; and a torch part equipped in one side of the drive part for performing welding along the rotation or movement of the drive part. The torch part comprises: a protruding part which is equipped in the upper end, and which is protruding in the direction of the drive part; and a torch rotation axis which is formed on the protruding part, and which is inserted into the drive part. Since the torch part is rotated around the torch rotation axis, a torch tip is exposed in a lateral direction. The drive part comprises: a dent part equipped in one side for accommodating the protruding part; and a penetration part formed in the dent part for allowing the torch rotation axis to be inserted. According to the present invention, a worker can easily replace a torch tip since the torch tip of a torch part is exposed in a lateral direction by vertically rotating the torch part around the upper end. Therefore, a welding apparatus is capable of improving work efficiency.
