Weldolets are the most common of all branch connections, and are welded onto the outlet pipe. The ends are bevelled to facilitate this process, and therefore the weldolet is considered a butt-weld fitting. Weldolet’s are designed to minimize stress concentrations and provide integral reinforcement.

A pipe weldolet makes a 90° branch connection and – comes in full size or reducing for a straight piece of pipe. A weldolet is designated by the run length by the branch length. For example a 1-inch weldolet on a 1-inch pipe would be a 1×1 Weldolet. A weldolet is designed to minimize stress concentrations and provide integral reinforcement without the need for reinforcing the weld.
