- Welding is a process that is used to attach pieces of metal to one another. In a certain welding process, small pieces of Al (s) and CuO (s) are placed in a crucible and ignited, causing the following highly exothermic reaction to occur. 2 Al+ 3 Cuo - 3 Cu + Al,O3 The copper and aluminum oxide melt. The molten aluminum oxide floats to the top of the crucible. When the steel disk below the crucible melts, the molten copper flows into the weld cavity and welds the pieces of metal together as it cools and solidifies. The setup is represented in the following diagram.

- The strength in the weld zone of an age-hardening aluminium alloy is often higher than in the heat affect zone (HAZ). Which of the following is NOT a reason for this? O The maximum temperature is higher in the weld pushing more of the hardening phase into solution. O Particles that don't dissolve might transform into equilibrium phases instead. This is more likely in the HAZ. O The greater dissolution of particles in the weld leads to greater solid solution strengthening. O The increase in solute in the matrix allows more subsequent natural aging to occur in the weld zone. O Particles in the HAZ tend to dissolve, while those in the weld coarsen. The increase in particle size and spacing reduces the strength of HAZ.arrow_forwardQuestion 1 1.1 Identify the weld defect shown in Figure 1 below. Provide reasons for your selection.
