Corrosion control methods

Corrosion may be defined as the method in which metals are attacked on their exteriors by gases existing in the atmosphere, converting them to their oxides, nitrides, sulfides, etc.

4) Which material cannot be weld using friction stir welding process? O Steel O Aluminum O Magnesium Gold

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.

3) In any structure, vicinity of weld zone which type of stress develops during the process of welding? Tensile residual stress Compressive residual stress Bending and tensile residual stress Bending and compressive residual stress
