A submerged arc welding operation takes place on 10 mm thick stainless steel plate, producing a butt weld as shown in Fig. 12.20c. The weld geometry can be approximated as a trapezoid with 15 mm and 10 mm as the top and bottom dimensions, respectively. If the voltage applied is 40 V at 400 A, estimate the welding speed if a stainless steel filler wire is used?
