A welded pipe tee is a reducing tee fitting that uses both socket and welded connections. Its usage steps are as follows:
1. First, cut the pipes at both ends to the required lengths using a cutting machine and grind them smooth.
2. Insert one end of the socket-type fitting into the end of one pipe, and the other end into the end of the other pipe.
3. Use a welding machine to weld the fitting together, ensuring a tight connection and a seal.
