WORKING PARAMETERS — NOT AN OFFICIAL COPY OF THE STANDARD
This tool is an auxiliary worksheet based on DVS 2207-1:2015-08 and equipment manufacturer guidance. It is not an official reproduction of the standard. Before field use, confirm the pipe material, fusion machine, wall thickness, ambient temperature, and project welding procedure.

Rules and field notes

t1 is controlled by the minimum bead height; it is not a fixed timer.
t3/t4 are maximum values; t5 is the minimum cooling time.
Heat-soak time is rounded up to 1 s; t3/t4 are rounded down to 0.1 s; cooling is rounded up to 0.1 min.
Do not confuse the 0.15 ± 0.01 N/mm² interface pressure with hydraulic gauge pressure.
Heat-soak interface pressure ≤ 0.01 N/mm²; heater temperature 220 ± 10°C.
Cooling time must not be extrapolated above 40°C.
