Question 22

_________ is most likely found in hard weld and heat-affected zones and in high strength components.

    Correct Answer: B

    Sulphide Stress Cracking (SSC) is most likely found in hard weld and heat-affected zones and in high strength components. This is because SSC occurs due to the presence of hydrogen sulfide, which can cause embrittlement and cracking in high hardness and high-strength materials.

Discussion
ahmadmmOption: B

Hard welds and hard spots within otherwise soft welds can arise with SAW when an active flux is used along with high welding voltage. This high hardness can lead to SSC
