Welding time (rotoweld)
0 likes510 views
This document compares welding times for different pipe diameters, thicknesses, and welding machines. It provides a table showing the welding time in minutes for various standard, heavy, and extra heavy wall pipes using the Rotoweld 2000 and Rotoweld 2500 machines. It also includes a formula to calculate the welding time for the Rotoweld 2500 based on pipe thickness, diameter, and deposition rate.
