Process energies. A bicycle maker manufactures frames from drawn low-carbon steel tubing by gas welding, followed by the application of a bakedon paint coating. One frame weighs 11 kg, the length of weld is 0.4 m, and the surface area of the frame is 0.6 m2 . Calculate the energy contributions of material and processing (use the data for “Deformation processing” for tube drawing) from the data sheet for mild steel in Chapter 15, and for welding and baked coating from Tables 6.5(c) and (d), and sum them to give a final energy total. Which contribution is the largest?
