ANGLE MEASURING APPARATUS FOR WELDING

摘要

PURPOSE: An angle measuring device for welding is provided to enable to adjust angles of the first and second arms, thereby easily measuring a dihedral angle of each circular pipe when welding the circular pipes where dihedral angles are continuously changed. CONSTITUTION: An angle measuring device(100) for welding comprises a base plate(110), a first arm(120) and a second arm(130). One side edge portion of the base plate is formed on an acute angle. The first arm is welded onto the base plate to be slide-moved in a longitudinal direction. One end portion of the second arm is welded so that the edge portion of the one side edge portion of the base plate is hinged and one end portion of the first arm is slide-moved in a longitudinal direction. A fixture(111) is arranged on the base plate. A first sliding hole(121) welded to the fixture along a longitudinal direction is formed in the first arm.
