Q6. An engineer is performing shielded metal-arc welding using stainless steel electrode to form a butt weld on 15 mm thick stainless steel plate. The weld geometry has a shape almost similar to trapezoid as shown in Figure 6. The top and bottom dimensions of the trapezoid are 20 mm and 15 mm, respectively with a height of 15 mm. 15 mm 20 mm 15 mm Figure 6: Schematic weld cross section The engineer applies similar condition of shielded metal-arc welding to form butt weld on each AISI 304 stainless steel plate and AISI 1010 steel plate. Evaluate the mechanical properties in terms of strength, hardness and ductility at the weld joint for each type of steel plate after the welding process. Assume that he uses electrode material which is compatible for each type of steel plate during the welding. (Word limit: ~100) (10 marks) Q6.
