Abstract
The present invention includes a welding jig having a first support plate and a second support plate rotatably connected to the first support plate. The second support plate has a template-shaped perimeter including arcuately shaped segments shaped to support pipe fittings of different sizes. By selectively positioning a particular segment and securing locking the particular segment in place, a particular pipe fitting such as a particular 90.degree. pipe elbow can be supported with one end resting on the selected particular segment and the other end resting on the first support plate. By this arrangement, particular pipe fitting can be supported in a predetermined and square position relative to a pipe, thus facilitating welding the particular pipe elbow to the pipe. This allows substantially a one-person welding operation.
