To reduce the possibility of cracking, which of the following maximum hardness levels is required for weldments in wet H2S service?

• A.HRC 32
• B.HRC 20
• C.HRC 25
• D.HRC 22

In magnetic particle examination, the yoke is placed parallel to the weld to detect cracks:

• A.Transverse to the weld.
• B.In the undercutting.
• C.Parallel to the weld.
• D.In the HAZ.

Prior to any welding, inspectors should review the:

• A.PQR to verify that the welder is qualified to perform the welding, given its position and process.
• B.WPS to verify that the welder is qualified to perform the welding, given its position and process.
• C.WPQ to verify that the specification in use is correct.
• D.WPQ to verify that the welder is qualified to perform the welding, given its position and process.

The simplest weldability tests are those that evaluate:

• A.Strength and ductility of the weld.
• B.Cracking and corrosion resistance of the weld.
• C.Ductility and hardness of the weld.
• D.Porosity and slag inclusions of the weld.

For design purposes, the maximum usefulness of a weldment under test is based upon the:

• A.Ultimate tensile strength.
• B.Yield strength.
• C.Hardness.
• D.Toughness.
