Textbook Question
Chapter 30, Problem 48QTP
A welding operation takes place on an aluminum-alloy plate. A pipe 2.5 in. in diameter, with a 0.20 in. wall thickness and a 2 in. length, is butt welded onto an angle iron 6 in. × 6 in. × 0.25 in. thick. The angle iron is of an L cross-section and has a length of 1 ft. If the weld zone in a gas tungsten arc welding process is approximately 0.5 in. wide, what would be the temperature increase of the entire structure due to the heat input from welding only? What if the process were an electron-beam welding operation, with a bead width of 0.08 in.? Assume that the electrode requires 1500 J and the aluminum alloy requires 1200 J to melt one gram.
