How much force should be applied to make a fusion joint?
After the pipe ends have been properly heated, the heater tool is removed and the molten pipe ends are brought together with sufficient force to properly mix the pipe materials and form a homogeneous joint. The pipe manufacturer’s instructions may specify either interface pressure or bead size of molten material as a guide for a proper joint. Always consult the pipe manufacturer’s recommended parameters and procedures. For pipe outside the United States, use the temperatures prescribed by applicable company, local, state, or federal standards.
