Productivity in Welding—Our Experience in Welding of Pressure Parts

"An important factor contributing to high productivity in welding is "Operator Factor" or "The Arc Time". This represents the percentage of the work day spent in actual welding. The average figure for "arc time" in moderately heavy and large works is approximately 50%. This can go up to 75%, where excellent handling facilities exist and the welders are operating under favourable conditions. Firms in U.S.A., U.K., and West Germany are extremely conscious of the importance of the "Operator Factor" in bringing down the welding costs.
