An alignment level tool aligns and holds metal plate edges in alignment for welding. The tool includes an L-shaped member and a series of work adaptor members. One arm of the L-shaped member has working screw threaded therein and the other arm has a mounting plate. The adaptor members include an L-shaped adaptor bracket, and a special V-shaped adaptor bracket. The L-shaped bracket has a short leg and a relatively long leg with each leg having an opening for bolting to the mounting plate of the L-shaped member. The bracket legs provide a two point support on a curved work plate or an offset planar support for an angulated plate. The adaptor bracket is temporarily welded to one work plate. The screw is aligned with the second work plate and is actuated to positively force the work plates into alignment for welding. The tool is then removed by bending with respect to the bracket weld to break the weld. A pair of opposed end-to-end pipe members or similar circular members are aligned by attaching a bracket having a mounting plate for attachment to the arm mounting plate and a V-shaped member attached to the bracket plate. The outer edges of the V-shaped member engage the pipe and one side is temporarily welded to the pipe. The L-shaped member aligns the screw in overlying alignment with the other pipe. The multiple part level tool including separate specially shaped adaptor and the common L-shaped member having the common mounting provides a versatile tool for aligning work pieces.
