- 1) The development of residual stresses in weld joint is due to? O Heat treatment operations OUnevenly distributed non-elastic strain ONon-uniform heating and cooling O All of the aboveSelect an appropriate electrode and flux of Submerged Arc Welding (SAW) process for nickel alloy steel.b) An I-beam made of 4140 steel is heat treated to form tempered martensite. It is then welded to a 4140 steel plate and cooled rapidly back to room temperature. During use, the I-beam and the plate experience an impact load, but it is the weld which breaks. What happened?
- Welding stainless steel is a complicated process because (uniform / intergranular / erosion) corrosion may happen, to avoid this issue post-weld-heat treatment is conducted to (precipitate / dissolve) carbide particles.8) The correct ways to control liquation cracking tendency in fusion weld joint are I. Use of filler metal that solidifies before the partially melted zone I. Use of single pass welding with higher net heat input instead of multipass welding III. Use of high energy density processes IV. Preheating the substrates V. Use of base metals with fine grain structure OI, II, and III II, and IV OII, IV, and V O II, III and IVQ1-A shielded metal arc welding operation is performed on steel at E = 30 volts and I = 225 amps. The heat transfer efficiency fi= 0.85 and melting efficiency f₂=0.75. The unit melting energy for steel Um = 10.2 J/mm3. Solve for: (a) the rate of heat generation at the weld and (b) the volume rate of metal welded
